I have a div with two images and an h1. All of them need to be vertically aligned within the div, next to each other. One of the images needs to be absolute positioned within the div.
What is the CSS needed for this to work on all common browsers?
<div id="header">
<img src=".." ></img>
<h1>testing...</h1>
<img src="..."></img>
</div>
Wow, this problem is popular. It's based on a misunderstanding in the vertical-align property. This excellent article explains it:
Understanding vertical-align, or "How (Not) To Vertically Center Content" by Gavin Kistner.
“How to center in CSS” is a great web tool which helps to find the necessary CSS centering attributes for different situations.
In a nutshell (and to prevent link rot):
Inline elements (and only inline elements) can be vertically aligned in their context via vertical-align: middle. However, the “context” isn’t the whole parent container height, it’s the height of the text line they’re in. jsfiddle example
For block elements, vertical alignment is harder and strongly depends on the specific situation:
If the inner element can have a fixed height, you can make its position absolute and specify its height, margin-top and top position. jsfiddle example
If the centered element consists of a single line and its parent height is fixed you can simply set the container’s line-height to fill its height. This method is quite versatile in my experience. jsfiddle example
… there are more such special cases.
Now that Flexbox support is increasing, this CSS applied to the containing element would vertically center all contained items (except for those items that specify the alignment themselves, e.g. align-self:start)
.container {
display: flex;
align-items: center;
}
Use the prefixed version if you also need to target Internet Explorer 10, and older (< 4.4 (KitKat)) Android browsers:
.container {
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-ms-flex-align: center;
-webkit-align-items: center;
-webkit-box-align: center;
align-items: center;
}
I used this very simple code:
div.ext-box { display: table; width:100%;}
div.int-box { display: table-cell; vertical-align: middle; }
<div class="ext-box">
<div class="int-box">
<h2>Some txt</h2>
<p>bla bla bla</p>
</div>
</div>
Obviously, whether you use a .class or an #id, the result won't change.
.outer {
display: flex;
align-items: center;
justify-content: center;
}
It worked for me:
.vcontainer {
min-height: 10em;
display: table-cell;
vertical-align: middle;
}
Vertically and horizontally align element
Use either of these. The result would be the same:
Bootstrap 4
CSS3
1. Bootstrap 4.3+
For vertical alignment: d-flex align-items-center
For horizontal alignment: d-flex justify-content-center
For vertical and horizontal alignment: d-flex align-items-center justify-content-center
.container {
height: 180px;
width:100%;
background-color: blueviolet;
}
.container > div {
background-color: white;
padding: 1rem;
}
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css"
rel="stylesheet"/>
<div class="d-flex align-items-center justify-content-center container">
<div>I am in Center</div>
</div>
2. CSS 3
.container {
height: 180px;
width:100%;
background-color: blueviolet;
}
.container > div {
background-color: white;
padding: 1rem;
}
.center {
display: flex;
align-items: center;
justify-content: center;
}
<div class="container center">
<div>I am in Center</div>
</div>
A technique from a friend of mine:
div:before {content:" "; display:inline-block; height:100%; vertical-align:middle;}
div p {display:inline-block;}
<div style="height:100px; border:1px solid;">
<p style="border:1px dotted;">I'm vertically centered.</p>
</div>
Demo here.
To position block elements to the center (works in Internet Explorer 9 and above), it needs a wrapper div:
.vcontainer {
position: relative;
top: 50%;
transform: translateY(-50%);
-webkit-transform: translateY(-50%);
}
Use this formula, and it will work always without cracks:
#outer {height: 400px; overflow: hidden; position: relative;}
#outer[id] {display: table; position: static;}
#middle {position: absolute; top: 50%;} /* For explorer only*/
#middle[id] {display: table-cell; vertical-align: middle; width: 100%;}
#inner {position: relative; top: -50%} /* For explorer only */
/* Optional: #inner[id] {position: static;} */
<div id="outer">
<div id="middle">
<div id="inner">
any text
any height
any content, for example generated from DB
everything is vertically centered
</div>
</div>
</div>
All of them need to be vertically aligned within the div
Aligned how? Tops of the images aligned with the top of the text?
One of the images needs to be absolute positioned within the div.
Absolutely positioned relative to the DIV? Perhaps you could sketch out what you're looking for...?
fd has described the steps for absolute positioning, as well as adjusting the display of the H1 element such that images will appear inline with it. To that, i'll add that you can align the images by use of the vertical-align style:
#header h1 { display: inline; }
#header img { vertical-align: middle; }
...this would put the header and images together, with top edges aligned. Other alignment options exist; see the documentation. You might also find it beneficial to drop the DIV and move the images inside the H1 element - this provides semantic value to the container, and removes the need to adjust the display of the H1:
<h1 id=header">
<img src=".." ></img>
testing...
<img src="..."></img>
</h1>
Almost all methods needs to specify the height, but often we don't have any heights.
So here is a CSS 3 three-line trick that doesn't require to know the height.
.element {
position: relative;
top: 50%;
transform: translateY(-50%);
}
It's supported even in IE9.
with its vendor prefixes:
.element {
position: relative;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
}

My trick is to put a table inside the div with one row and one column, set 100% of width and height, and the property vertical-align:middle:
<div>
<table style="width:100%; height:100%;">
<tr>
<td style="vertical-align:middle;">
BUTTON TEXT
</td>
</tr>
</table>
</div>

Using display flex, first you need to wrap the container of the item that you want to align:
<div class="outdiv">
<div class="indiv">
<span>test1</span>
<span>test2</span>
</div>
</div>
Then apply the following CSS content to wrap div or outdiv in my example:
.outdiv {
display: flex;
justify-content: center;
align-items: center;
}
Using CSS to vertical center, you can let the outer containers act like a table, and the content as a table cell. In this format your objects will stay centered. :)
I nested multiple objects in JSFiddle for an example, but the core idea is like this:
HTML
<div class="circle">
<div class="content">
Some text
</div>
</div>
CSS
.circle {
/* Act as a table so we can center vertically its child */
display: table;
/* Set dimensions */
height: 200px;
width: 200px;
/* Horizontal center text */
text-align: center;
/* Create a red circle */
border-radius: 100%;
background: red;
}
.content {
/* Act as a table cell */
display: table-cell;
/* And now we can vertically center! */
vertical-align: middle;
/* Some basic markup */
font-size: 30px;
font-weight: bold;
color: white;
}
The multiple objects example:
HTML
<div class="container">
<div class="content">
<div class="centerhoriz">
<div class="circle">
<div class="content">
Some text
</div><!-- content -->
</div><!-- circle -->
<div class="square">
<div class="content">
<div id="smallcircle"></div>
</div><!-- content -->
</div><!-- square -->
</div><!-- center-horiz -->
</div><!-- content -->
</div><!-- container -->
CSS
.container {
display: table;
height: 500px;
width: 300px;
text-align: center;
background: lightblue;
}
.centerhoriz {
display: inline-block;
}
.circle {
display: table;
height: 200px;
width: 200px;
text-align: center;
background: red;
border-radius: 100%;
margin: 10px;
}
.square {
display: table;

I have found a new workaround to vertically align multiple text-lines in a div using CSS 3 (and I am also using bootstrap v3 grid system to beautify the UI), which is as below:
.immediate-parent-of-text-containing-div {
height: 50px; /* Or any fixed height that suits you. */
}
.text-containing-div {
display: inline-grid;
align-items: center;
text-align: center;
height: 100%;
}
As per my understanding, the immediate parent of text containing element must have some height.
We may use a CSS function calculation to calculate the size of the element and then position the child element accordingly.
Example HTML:
<div class="box">
<span>Some Text</span>
</div>
And CSS:
.box {
display: block;
background: #60D3E8;
position: relative;
width: 300px;
height: 200px;
text-align: center;
}
.box span {
font: bold 20px/20px 'source code pro', sans-serif;
position: absolute;
left: 0;
right: 0;
top: calc(50% - 10px);
}
a {
color: white;
text-decoration: none;
}
Demo created here: https://jsfiddle.net/xnjq1t22/
This solution works well with responsive div height and width as well.
Note: The calc function is not tested for compatiblity with old browsers.
Using only a Bootstrap class:
div: class="container d-flex"
element inside div: class="m-auto"
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.5.3/css/bootstrap.min.css" crossorigin="anonymous">
<div class="container d-flex mt-5" style="height:110px; background-color: #333;">
<h2 class="m-auto">H➲VER➾M⇡ND</h2>
</div>
By default h1 is a block element and will render on the line after the first img, and will cause the second img to appear on the line following the block.
To stop this from occurring you can set the h1 to have inline flow behaviour:
#header > h1 { display: inline; }
As for absolutely positioning the img inside the div, you need to set the containing div to have a "known size" before this will work properly. In my experience, you also need to change the position attribute away from the default - position: relative works for me:
#header { position: relative; width: 20em; height: 20em; }
#img-for-abs-positioning { position: absolute; top: 0; left: 0; }
If you can get that to work, you might want to try progressively removing the height, width, position attributes from div.header to get the minimal required attributes to get the effect you want.
UPDATE:
Here is a complete example that works on Firefox 3:

My new favorite way to do it is with a CSS grid:

}
img {

height: 120px;
}
<div class="wrapper">

Just use a one-cell table inside the div! Just set the cell and table height and with to 100% and you can use the vertical-align.
A one-cell table inside the div handles the vertical-align and is backward compatible back to the Stone Age!
For me, it worked this way:
<div style="width:70px; height:68px; float:right; display: table-cell; line-height: 68px">
Login
</div>
The "a" element converted to a button, using Bootstrap classes, and it is now vertically centered inside an outer "div".
I have been using the following solution (with no positioning and no line height) since over a year, it works with Internet Explorer 7 and Internet Explorer 8 as well.
<style>
.outer {
font-size: 0;
width: 400px;
height: 400px;
background: orange;
text-align: center;
display: inline-block;
}
.outer .emptyDiv {
height: 100%;
background: orange;
visibility: collapse;
}
.outer .inner {
padding: 10px;
background: red;
font: bold 12px Arial;
}
.verticalCenter {
display: inline-block;
*display: inline;
zoom: 1;
vertical-align: middle;
}
</style>
<div class="outer">
<div class="emptyDiv verticalCenter"></div>
<div class="inner verticalCenter">
<p>Line 1</p>
<p>Line 2</p>
</div>
</div>
This is my personal solution for an i element inside a div.

How can I center align (horizontally) an image inside its container div?
Here's the HTML and CSS. I have also included the CSS for the other elements of the thumbnail. It runs in descending order so the highest element is the container of everything and the lowest is inside everything.
#thumbnailwrapper {
color: #2A2A2A;
margin-right: 5px;
border-radius: 0.2em;
margin-bottom: 5px;
background-color: #E9F7FE;
padding: 5px;
border: thin solid #DADADA;
font-size: 15px
}
#artiststhumbnail {
width: 120px;
height: 108px;
overflow: hidden;
border: thin solid #DADADA;
background-color: white;
}
#artiststhumbnail:hover {
left: 50px
}
<!--link here-->
<a href="NotByDesign">
<div id="thumbnailwrapper">
<a href="NotByDesign">
<!--name here-->
<b>Not By Design</b>
<br>
<div id="artiststhumbnail">
<a href="NotByDesign">
<!--image here-->
<img src="../files/noprofile.jpg" height="100%" alt="Not By Design" border="1" />
</a>
</div>
<div id="genre">Punk</div>
</div>
Okay, I have added the markup without the PHP in so should be easier to see. Neither solution seems to work in practice. The text at top and bottom cannot be centered and the image should be centered within its container div. The container has overflow hidden so I want to see the center of the image as that's normally where the focus is.
#artiststhumbnail a img {
display:block;
margin:auto;
}
Here's my solution in: http://jsfiddle.net/marvo/3k3CC/2/
CSS flexbox can do it with justify-content: center on the image parent element. To preserve the aspect ratio of the image, add align-self: flex-start; to it.
HTML
<div class="image-container">
<img src="http://placehold.it/100x100" />
</div>
CSS
.image-container {
display: flex;
justify-content: center;
}
Output:
body {
background: lightgray;
}
.image-container {
width: 200px;
display: flex;
justify-content: center;
margin: 10px;
padding: 10px;
/* Material design properties */
background: #fff;
box-shadow: 0 2px 2px 0 rgba(0, 0, 0, 0.14), 0 3px 1px -2px rgba(0, 0, 0, 0.2), 0 1px 5px 0 rgba(0, 0, 0, 0.12);
}
.image-2 {
width: 500px;
align-self: flex-start; /* to preserve image aspect ratio */
}
.image-3 {
width: 300px;
align-self: flex-start; /* to preserve image aspect ratio */
}
<div class="image-container">
<img src="http://placehold.it/100x100" />
</div>
<div class="image-container image-2">
<img src="http://placehold.it/100x100/333" />
</div>
<div class="image-container image-3">
<img src="http://placehold.it/100x100/666" />
</div>
I just found this solution below on the W3 CSS page and it answered my problem.
img {
display: block;
margin-left: auto;
margin-right: auto;
}
Source: http://www.w3.org/Style/Examples/007/center.en.html
This also would do it
#imagewrapper {
text-align:center;
}
#imagewrapper img {
display:inline-block;
margin:0 5px;
}
The best thing I have found (that seems to work in all browsers) for centering an image, or any element, horizontally is to create a CSS class and include the following parameters:
CSS
.center {
position: relative; /* where the next element will be automatically positioned */
display: inline-block; /* causes element width to shrink to fit content */
left: 50%; /* moves left side of image/element to center of parent element */
transform: translate(-50%); /* centers image/element on "left: 50%" position */
}
You can then apply the CSS class you created to your tag as follows:
HTML
<img class="center" src="image.jpg" />
You can also inline the CSS in your element(s) by doing the following:
<img style="position: relative; display: inline-block; left: 50%; transform: translate(-50%);" src ="image.jpg" />
...but I wouldn't recommend writing CSS inline because then you have to make multiple changes in all your tags using your centering CSS code if you ever want to change the style.
This is what I ended up doing:
<div style="height: 600px">
<img src="assets/zzzzz.png" alt="Error" style="max-width: 100%;
max-height: 100%; display:block; margin:auto;" />
</div>
Which will limit the image height to 600px and will horizontally-center (or resize down if the parent width is smaller) to the parent container, maintaining proportions.
I am going to go out on a limb and say that the following is what you are after.
Note, the following I believe was accidentally omitted in the question (see comment):
<div id="thumbnailwrapper"> <!-- <<< This opening element -->
<div id="artiststhumbnail">
...
So what you need is:
#artiststhumbnail {
width:120px;
height:108px;
margin: 0 auto; /* <<< This line here. */
...
}
http://jsfiddle.net/userdude/XStjX/3/
yeah, the code like this work fine
<div>
<img/>
</div>
but just to remind u, the style for image
object-fit : *depend on u*
so the final code be like Example
div {
display: flex;
justify-content: center;
align-items: center;
}
div img {
object-fit: contain;
}
<div style="border: 1px solid red;">
<img src="https://img.joomcdn.net/9dd32cbfa0cdd7f48ca094972ca47727cd3cd82c_original.jpeg" alt="" srcset="" style="
border-radius: 50%;
height: 7.5rem;
width: 7.5rem;
object-fit: contain;" />
</div>
Add this to your CSS:
#artiststhumbnail a img {
display: block;
margin-left: auto;
margin-right: auto;
}
Just referencing a child element which in that case is the image.
To center an image horizontally, this works:
<p style="text-align:center"><img src=""></p>
Put the picture inside a newDiv.
Make the width of the containing div the same as the image.
Apply margin: 0 auto; to the newDiv.
That should center the div within the container.
Use positioning. The following worked for me... (Horizontally and Vertically Centered)
With zoom to the center of the image (image fills the div):
div{
display:block;
overflow:hidden;
width: 70px;
height: 70px;
position: relative;
}
div img{
min-width: 70px;
min-height: 70px;
max-width: 250%;
max-height: 250%;
top: -50%;
left: -50%;
bottom: -50%;
right: -50%;
position: absolute;
}
Without zoom to the center of the image (image does not fill the div):
div{
display:block;
overflow:hidden;
width: 100px;
height: 100px;
position: relative;
}
div img{
width: 70px;
height: 70px;
top: 50%;
left: 50%;
bottom: 50%;
right: 50%;
position: absolute;
}
Center a image in a div
/* standar */
div, .flexbox-div {
position: relative;
width: 100%;
height: 100px;
margin: 10px;
background-color: grey;
}
img {
border: 3px solid red;
width: 75px;
height: 75px;
}
/* || standar */
/* transform */
.transform {

I have tried a few ways. But this way works perfectly for me
<img src="~/images/btn.png" class="img-responsive" id="hide" style="display: block; margin-left: auto; margin-right: auto;" />
Put an equal pixel padding for left and right:
<div id="artiststhumbnail" style="padding-left:ypx;padding-right:ypx">
A responsive way to center an image can be like this:
.center {
display: block;
margin: auto;
max-width: 100%;
max-height: 100%;
}
you can align your content using flex box with minimum code

If you have to do this inline (such as when using an input box),
here is a quick hack that worked for me: surround your (image link in this case)
in a div with style="text-align:center"
<div style="text-align:center">

To center a image use this css. You have to give width at first of the image.
img{
width: 300px;
position: fixed;
left0;
right:0;
}
I have a div with two images and an h1. All of them need to be vertically aligned within the div, next to each other. One of the images needs to be absolute positioned within the div.
What is the CSS needed for this to work on all common browsers?

Wow, this problem is popular. It's based on a misunderstanding in the vertical-align property. This excellent article explains it:
Understanding vertical-align, or "How (Not) To Vertically Center Content" by Gavin Kistner.
“How to center in CSS” is a great web tool which helps to find the necessary CSS centering attributes for different situations.
In a nutshell (and to prevent link rot):
Inline elements (and only inline elements) can be vertically aligned in their context via vertical-align: middle. However, the “context” isn’t the whole parent container height, it’s the height of the text line they’re in. jsfiddle example
For block elements, vertical alignment is harder and strongly depends on the specific situation:
If the inner element can have a fixed height, you can make its position absolute and specify its height, margin-top and top position. jsfiddle example
If the centered element consists of a single line and its parent height is fixed you can simply set the container’s line-height to fill its height. This method is quite versatile in my experience. jsfiddle example
… there are more such special cases.
Now that Flexbox support is increasing, this CSS applied to the containing element would vertically center all contained items (except for those items that specify the alignment themselves, e.g. align-self:start)
.container {
display: flex;
align-items: center;
}
Use the prefixed version if you also need to target Internet Explorer 10, and older (< 4.4 (KitKat)) Android browsers:
.container {
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-ms-flex-align: center;
-webkit-align-items: center;
-webkit-box-align: center;
align-items: center;
}
I used this very simple code:
div.ext-box { display: table; width:100%;}
div.int-box { display: table-cell; vertical-align: middle; }
<div class="ext-box">
<div class="int-box">
<h2>Some txt</h2>
<p>bla bla bla</p>
</div>
</div>
Obviously, whether you use a .class or an #id, the result won't change.
.outer {
display: flex;
align-items: center;
justify-content: center;
}
It worked for me:
.vcontainer {
min-height: 10em;
display: table-cell;
vertical-align: middle;
}
Vertically and horizontally align element
Use either of these. The result would be the same:
Bootstrap 4

1. Bootstrap 4.3+
For vertical alignment: d-flex align-items-center
For horizontal alignment: d-flex justify-content-center
For vertical and horizontal alignment: d-flex align-items-center justify-content-center

width:100%;

}

.container {

width:100%;
background-color: blueviolet;
}
.container > div {
background-color: white;
padding: 1rem;

.center {
display: flex;
align-items: center;
justify-content: center;
}
<div class="container center">
<div>I am in Center</div>
</div>
A technique from a friend of mine:
div:before {content:" "; display:inline-block; height:100%; vertical-align:middle;}
div p {display:inline-block;}
<div style="height:100px; border:1px solid;">
<p style="border:1px dotted;">I'm vertically centered.</p>
</div>
Demo here.
To position block elements to the center (works in Internet Explorer 9 and above), it needs a wrapper div:
.vcontainer {
position: relative;
top: 50%;
transform: translateY(-50%);
-webkit-transform: translateY(-50%);
}
Use this formula, and it will work always without cracks:
#outer {height: 400px; overflow: hidden; position: relative;}
#outer[id] {display: table; position: static;}
#middle {position: absolute; top: 50%;} /* For explorer only*/
#middle[id] {display: table-cell; vertical-align: middle; width: 100%;}
#inner {position: relative; top: -50%} /* For explorer only */
/* Optional: #inner[id] {position: static;} */
<div id="outer">
<div id="middle">
<div id="inner">
any text
any height
any content, for example generated from DB
everything is vertically centered
</div>
</div>
</div>
All of them need to be vertically aligned within the div
Aligned how? Tops of the images aligned with the top of the text?
One of the images needs to be absolute positioned within the div.
Absolutely positioned relative to the DIV? Perhaps you could sketch out what you're looking for...?
fd has described the steps for absolute positioning, as well as adjusting the display of the H1 element such that images will appear inline with it. To that, i'll add that you can align the images by use of the vertical-align style:
#header h1 { display: inline; }
#header img { vertical-align: middle; }
...this would put the header and images together, with top edges aligned. Other alignment options exist; see the documentation. You might also find it beneficial to drop the DIV and move the images inside the H1 element - this provides semantic value to the container, and removes the need to adjust the display of the H1:
<h1 id=header">
<img src=".." ></img>
testing...
<img src="..."></img>
</h1>
Almost all methods needs to specify the height, but often we don't have any heights.
So here is a CSS 3 three-line trick that doesn't require to know the height.
.element {
position: relative;
top: 50%;
transform: translateY(-50%);
}
It's supported even in IE9.
with its vendor prefixes:
.element {
position: relative;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
}

My trick is to put a table inside the div with one row and one column, set 100% of width and height, and the property vertical-align:middle:
<div>
<table style="width:100%; height:100%;">
<tr>
<td style="vertical-align:middle;">
BUTTON TEXT
</td>
</tr>
</table>
</div>
Fiddle:
http://jsfiddle.net/joan16v/sbqjnn9q/
Using display flex, first you need to wrap the container of the item that you want to align:
<div class="outdiv">
<div class="indiv">
<span>test1</span>
<span>test2</span>
</div>
</div>
Then apply the following CSS content to wrap div or outdiv in my example:
.outdiv {
display: flex;
justify-content: center;
align-items: center;
}
Using CSS to vertical center, you can let the outer containers act like a table, and the content as a table cell. In this format your objects will stay centered. :)
I nested multiple objects in JSFiddle for an example, but the core idea is like this:
HTML
<div class="circle">
<div class="content">
Some text
</div>
</div>
CSS
.circle {
/* Act as a table so we can center vertically its child */
display: table;
/* Set dimensions */
height: 200px;
width: 200px;
/* Horizontal center text */
text-align: center;
/* Create a red circle */
border-radius: 100%;
background: red;
}
.content {
/* Act as a table cell */
display: table-cell;
/* And now we can vertically center! */
vertical-align: middle;
/* Some basic markup */
font-size: 30px;
font-weight: bold;
color: white;
}
The multiple objects example:
HTML
<div class="container">
<div class="content">
<div class="centerhoriz">
<div class="circle">
<div class="content">
Some text
</div><!-- content -->
</div><!-- circle -->
<div class="square">
<div class="content">
<div id="smallcircle"></div>
</div><!-- content -->
</div><!-- square -->
</div><!-- center-horiz -->
</div><!-- content -->
</div><!-- container -->
CSS
.container {
display: table;
height: 500px;
width: 300px;
text-align: center;
background: lightblue;
}
.centerhoriz {
display: inline-block;
}
.circle {
display: table;
height: 200px;
width: 200px;
text-align: center;
background: red;
border-radius: 100%;

I have found a new workaround to vertically align multiple text-lines in a div using CSS 3 (and I am also using bootstrap v3 grid system to beautify the UI), which is as below:
.immediate-parent-of-text-containing-div {
height: 50px; /* Or any fixed height that suits you. */
}
.text-containing-div {
display: inline-grid;
align-items: center;
text-align: center;
height: 100%;
}
As per my understanding, the immediate parent of text containing element must have some height.
We may use a CSS function calculation to calculate the size of the element and then position the child element accordingly.
Example HTML:
<div class="box">
<span>Some Text</span>
</div>
And CSS:
.box {
display: block;
background: #60D3E8;
position: relative;
width: 300px;
height: 200px;
text-align: center;
}
.box span {
font: bold 20px/20px 'source code pro', sans-serif;
position: absolute;
left: 0;
right: 0;
top: calc(50% - 10px);
}
a {
color: white;
text-decoration: none;
}
Demo created here: https://jsfiddle.net/xnjq1t22/
This solution works well with responsive div height and width as well.
Note: The calc function is not tested for compatiblity with old browsers.
Using only a Bootstrap class:
div: class="container d-flex"
element inside div: class="m-auto"
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.5.3/css/bootstrap.min.css" crossorigin="anonymous">
<div class="container d-flex mt-5" style="height:110px; background-color: #333;">
<h2 class="m-auto">H➲VER➾M⇡ND</h2>
</div>
By default h1 is a block element and will render on the line after the first img, and will cause the second img to appear on the line following the block.
To stop this from occurring you can set the h1 to have inline flow behaviour:
#header > h1 { display: inline; }
As for absolutely positioning the img inside the div, you need to set the containing div to have a "known size" before this will work properly. In my experience, you also need to change the position attribute away from the default - position: relative works for me:
#header { position: relative; width: 20em; height: 20em; }
#img-for-abs-positioning { position: absolute; top: 0; left: 0; }
If you can get that to work, you might want to try progressively removing the height, width, position attributes from div.header to get the minimal required attributes to get the effect you want.
UPDATE:
Here is a complete example that works on Firefox 3:

Just use a one-cell table inside the div! Just set the cell and table height and with to 100% and you can use the vertical-align.
A one-cell table inside the div handles the vertical-align and is backward compatible back to the Stone Age!
For me, it worked this way:
<div style="width:70px; height:68px; float:right; display: table-cell; line-height: 68px">
Login
</div>
The "a" element converted to a button, using Bootstrap classes, and it is now vertically centered inside an outer "div".
I have been using the following solution (with no positioning and no line height) since over a year, it works with Internet Explorer 7 and Internet Explorer 8 as well.
<style>
.outer {
font-size: 0;
width: 400px;
height: 400px;
background: orange;
text-align: center;
display: inline-block;
}
.outer .emptyDiv {
height: 100%;
background: orange;
visibility: collapse;
}
.outer .inner {
padding: 10px;
background: red;
font: bold 12px Arial;
}
.verticalCenter {
display: inline-block;
*display: inline;
zoom: 1;
vertical-align: middle;
}
</style>
<div class="outer">
<div class="emptyDiv verticalCenter"></div>
<div class="inner verticalCenter">
<p>Line 1</p>
<p>Line 2</p>
</div>
</div>
This is my personal solution for an i element inside a div.

A technique from a friend of mine:
div:before {content:" "; display:inline-block; height:100%; vertical-align:middle;}
div p {display:inline-block;}
<div style="height:100px; border:1px solid;">
<p style="border:1px dotted;">I'm vertically centered.</p>
</div>
Demo here.
To position block elements to the center (works in Internet Explorer 9 and above), it needs a wrapper div:
.vcontainer {
position: relative;
top: 50%;
transform: translateY(-50%);
-webkit-transform: translateY(-50%);
}
Use this formula, and it will work always without cracks:
#outer {height: 400px; overflow: hidden; position: relative;}
#outer[id] {display: table; position: static;}
#middle {position: absolute; top: 50%;} /* For explorer only*/
#middle[id] {display: table-cell; vertical-align: middle; width: 100%;}
#inner {position: relative; top: -50%} /* For explorer only */
/* Optional: #inner[id] {position: static;} */
<div id="outer">
<div id="middle">
<div id="inner">
any text
any height
any content, for example generated from DB
everything is vertically centered
</div>
</div>
</div>
All of them need to be vertically aligned within the div
Aligned how? Tops of the images aligned with the top of the text?
One of the images needs to be absolute positioned within the div.
Absolutely positioned relative to the DIV? Perhaps you could sketch out what you're looking for...?
fd has described the steps for absolute positioning, as well as adjusting the display of the H1 element such that images will appear inline with it. To that, i'll add that you can align the images by use of the vertical-align style:
#header h1 { display: inline; }
#header img { vertical-align: middle; }
...this would put the header and images together, with top edges aligned. Other alignment options exist; see the documentation. You might also find it beneficial to drop the DIV and move the images inside the H1 element - this provides semantic value to the container, and removes the need to adjust the display of the H1:
<h1 id=header">
<img src=".." ></img>

Almost all methods needs to specify the height, but often we don't have any heights.

Using display flex, first you need to wrap the container of the item that you want to align:
<div class="outdiv">
<div class="indiv">
<span>test1</span>
<span>test2</span>
</div>
</div>
Then apply the following CSS content to wrap div or outdiv in my example:
.outdiv {
display: flex;
justify-content: center;
align-items: center;
}
Using CSS to vertical center, you can let the outer containers act like a table, and the content as a table cell. In this format your objects will stay centered. :)
I nested multiple objects in JSFiddle for an example, but the core idea is like this:
HTML
<div class="circle">

.circle {
/* Act as a table so we can center vertically its child */
display: table;
/* Set dimensions */
height: 200px;
width: 200px;
/* Horizontal center text */
text-align: center;
/* Create a red circle */
border-radius: 100%;
background: red;
}
.content {
/* Act as a table cell */
display: table-cell;
/* And now we can vertically center! */
vertical-align: middle;
/* Some basic markup */
font-size: 30px;

I have found a new workaround to vertically align multiple text-lines in a div using CSS 3 (and I am also using bootstrap v3 grid system to beautify the UI), which is as below:
.immediate-parent-of-text-containing-div {
height: 50px; /* Or any fixed height that suits you. */
}
.text-containing-div {
display: inline-grid;
align-items: center;
text-align: center;
height: 100%;
}
As per my understanding, the immediate parent of text containing element must have some height.
We may use a CSS function calculation to calculate the size of the element and then position the child element accordingly.
Example HTML:
<div class="box">
<span>Some Text</span>
</div>
And CSS:
.box {
display: block;
background: #60D3E8;
position: relative;
width: 300px;
height: 200px;
text-align: center;
}
.box span {
font: bold 20px/20px 'source code pro', sans-serif;
position: absolute;
left: 0;
right: 0;
top: calc(50% - 10px);
}
a {
color: white;
text-decoration: none;
}
Demo created here: https://jsfiddle.net/xnjq1t22/
This solution works well with responsive div height and width as well.
Note: The calc function is not tested for compatiblity with old browsers.
Using only a Bootstrap class:
div: class="container d-flex"
element inside div: class="m-auto"
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.5.3/css/bootstrap.min.css" crossorigin="anonymous">
<div class="container d-flex mt-5" style="height:110px; background-color: #333;">
<h2 class="m-auto">H➲VER➾M⇡ND</h2>
</div>
By default h1 is a block element and will render on the line after the first img, and will cause the second img to appear on the line following the block.
To stop this from occurring you can set the h1 to have inline flow behaviour:
#header > h1 { display: inline; }
As for absolutely positioning the img inside the div, you need to set the containing div to have a "known size" before this will work properly. In my experience, you also need to change the position attribute away from the default - position: relative works for me:
#header { position: relative; width: 20em; height: 20em; }
#img-for-abs-positioning { position: absolute; top: 0; left: 0; }
If you can get that to work, you might want to try progressively removing the height, width, position attributes from div.header to get the minimal required attributes to get the effect you want.
UPDATE:
Here is a complete example that works on Firefox 3:

Just use a one-cell table inside the div! Just set the cell and table height and with to 100% and you can use the vertical-align.
A one-cell table inside the div handles the vertical-align and is backward compatible back to the Stone Age!
For me, it worked this way:
<div style="width:70px; height:68px; float:right; display: table-cell; line-height: 68px">
Login
</div>
The "a" element converted to a button, using Bootstrap classes, and it is now vertically centered inside an outer "div".
I have been using the following solution (with no positioning and no line height) since over a year, it works with Internet Explorer 7 and Internet Explorer 8 as well.
<style>
.outer {
font-size: 0;
width: 400px;
height: 400px;
background: orange;
text-align: center;
display: inline-block;
}
.outer .emptyDiv {
height: 100%;
background: orange;
visibility: collapse;
}
.outer .inner {
padding: 10px;
background: red;
font: bold 12px Arial;
}
.verticalCenter {
display: inline-block;
*display: inline;
zoom: 1;
vertical-align: middle;
}
</style>
<div class="outer">
<div class="emptyDiv verticalCenter"></div>
<div class="inner verticalCenter">
<p>Line 1</p>
<p>Line 2</p>
</div>
</div>
This is my personal solution for an i element inside a div.

Browser Coverage
I have a div with two images and an h1. All of them need to be vertically aligned within the div, next to each other. One of the images needs to be absolute positioned within the div.
What is the CSS needed for this to work on all common browsers?
<div id="header">
<img src=".." ></img>
<h1>testing...</h1>
<img src="..."></img>
</div>
Wow, this problem is popular. It's based on a misunderstanding in the vertical-align property. This excellent article explains it:
Understanding vertical-align, or "How (Not) To Vertically Center Content" by Gavin Kistner.
“How to center in CSS” is a great web tool which helps to find the necessary CSS centering attributes for different situations.
In a nutshell (and to prevent link rot):
Inline elements (and only inline elements) can be vertically aligned in their context via vertical-align: middle. However, the “context” isn’t the whole parent container height, it’s the height of the text line they’re in. jsfiddle example
For block elements, vertical alignment is harder and strongly depends on the specific situation:
If the inner element can have a fixed height, you can make its position absolute and specify its height, margin-top and top position. jsfiddle example
If the centered element consists of a single line and its parent height is fixed you can simply set the container’s line-height to fill its height. This method is quite versatile in my experience. jsfiddle example
… there are more such special cases.
Now that Flexbox support is increasing, this CSS applied to the containing element would vertically center all contained items (except for those items that specify the alignment themselves, e.g. align-self:start)
.container {
display: flex;
align-items: center;
}
Use the prefixed version if you also need to target Internet Explorer 10, and older (< 4.4 (KitKat)) Android browsers:
.container {
display: -ms-flexbox;
display: -webkit-flex;
display: flex;
-ms-flex-align: center;
-webkit-align-items: center;
-webkit-box-align: center;
align-items: center;
}
I used this very simple code:
div.ext-box { display: table; width:100%;}
div.int-box { display: table-cell; vertical-align: middle; }
<div class="ext-box">
<div class="int-box">
<h2>Some txt</h2>
<p>bla bla bla</p>
</div>
</div>
Obviously, whether you use a .class or an #id, the result won't change.
.outer {
display: flex;
align-items: center;
justify-content: center;
}
It worked for me:
.vcontainer {
min-height: 10em;
display: table-cell;
vertical-align: middle;
}
Vertically and horizontally align element
Use either of these. The result would be the same:
Bootstrap 4
CSS3
1. Bootstrap 4.3+
For vertical alignment: d-flex align-items-center
For horizontal alignment: d-flex justify-content-center
For vertical and horizontal alignment: d-flex align-items-center justify-content-center

We may use a CSS function calculation to calculate the size of the element and then position the child element accordingly.
Example HTML:
<div class="box">
<span>Some Text</span>
</div>
And CSS:
.box {
display: block;
background: #60D3E8;
position: relative;
width: 300px;
height: 200px;
text-align: center;
}
.box span {
font: bold 20px/20px 'source code pro', sans-serif;
position: absolute;
left: 0;
right: 0;
top: calc(50% - 10px);
}
a {
color: white;
text-decoration: none;
}

This solution works well with responsive div height and width as well.
Note: The calc function is not tested for compatiblity with old browsers.
Using only a Bootstrap class:
div: class="container d-flex"
element inside div: class="m-auto"
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.5.3/css/bootstrap.min.css" crossorigin="anonymous">
<div class="container d-flex mt-5" style="height:110px; background-color: #333;">
<h2 class="m-auto">H➲VER➾M⇡ND</h2>
</div>
By default h1 is a block element and will render on the line after the first img, and will cause the second img to appear on the line following the block.
To stop this from occurring you can set the h1 to have inline flow behaviour:
#header > h1 { display: inline; }
As for absolutely positioning the img inside the div, you need to set the containing div to have a "known size" before this will work properly. In my experience, you also need to change the position attribute away from the default - position: relative works for me:
#header { position: relative; width: 20em; height: 20em; }
#img-for-abs-positioning { position: absolute; top: 0; left: 0; }
If you can get that to work, you might want to try progressively removing the height, width, position attributes from div.header to get the minimal required attributes to get the effect you want.
UPDATE:
Here is a complete example that works on Firefox 3:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
<title>Example of vertical positioning inside a div</title>
<style type="text/css">
#header > h1 { display: inline; }
#header { border: solid 1px red;
position: relative; }
#img-for-abs-positioning { position: absolute;
bottom: -1em; right: 2em; }
</style>
</head>
<body>
<div id="header">
<img src="#" alt="Image 1" width="40" height="40" />
<h1>Header</h1>
<img src="#" alt="Image 2" width="40" height="40"
id="img-for-abs-positioning" />
</div>
</body>
</html>
My new favorite way to do it is with a CSS grid:
/* technique */
.wrapper {
display: inline-grid;
grid-auto-flow: column;
align-items: center;
justify-content: center;
}
/* visual emphasis */
.wrapper {
border: 1px solid red;
height: 180px;
width: 400px;
}
img {
width: 100px;
height: 80px;
background: #fafafa;
}
img:nth-child(2) {
height: 120px;
}
<div class="wrapper">
<img src="https://source.unsplash.com/random/100x80/?bear">
<img src="https://source.unsplash.com/random/100x120/?lion">

</div>
Just use a one-cell table inside the div! Just set the cell and table height and with to 100% and you can use the vertical-align.
A one-cell table inside the div handles the vertical-align and is backward compatible back to the Stone Age!
For me, it worked this way:
<div style="width:70px; height:68px; float:right; display: table-cell; line-height: 68px">
Login
</div>
The "a" element converted to a button, using Bootstrap classes, and it is now vertically centered inside an outer "div".
I have been using the following solution (with no positioning and no line height) since over a year, it works with Internet Explorer 7 and Internet Explorer 8 as well.
<style>
.outer {
font-size: 0;
width: 400px;
height: 400px;
background: orange;
text-align: center;
display: inline-block;
}
.outer .emptyDiv {
height: 100%;
background: orange;
visibility: collapse;
}
.outer .inner {
padding: 10px;
background: red;
font: bold 12px Arial;
}
.verticalCenter {
display: inline-block;
*display: inline;
zoom: 1;
vertical-align: middle;
}
</style>
<div class="outer">
<div class="emptyDiv verticalCenter"></div>
<div class="inner verticalCenter">
<p>Line 1</p>
<p>Line 2</p>
</div>
</div>
This is my personal solution for an i element inside a div.
JSFiddle Example
HTML
<div class="circle">
<i class="fa fa-plus icon">
</i></div>
CSS
.circle {
border-radius: 50%;
color: blue;
background-color: red;
height:100px;
width:100px;
text-align: center;
line-height: 100px;
}
.icon {
font-size: 50px;
vertical-align: middle;
}
Just this:
<div>
<table style="width: 100%; height: 100%">
<tr>
<td style="width: 100%; height: 100%; vertical-align: middle;">
What ever you want vertically-aligned
</td>
</tr>
</table>
</div>
A one-cell table inside the div handles the vertical-align and is backward compatible back to the Stone Age!
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
<head>
<style type="text/css">
#style_center { position:relative; top:50%; left:50%; }
#style_center_absolute { position:absolute; top:50px; left:50px; }
<!--#style_center { position:relative; top:50%; left:50%; height:50px; margin-top:-25px; }-->
</style>
</head>
<body>
<div style="height:200px; width:200px; background:#00FF00">
<div id="style_center">+</div>
</div>
</body>
</html>
Here is just another (responsive) approach:
html,
body {
height: 100%;
}
body {
margin: 0;
}
.table {
display: table;
width: auto;
table-layout:auto;
height: 100%;
}
.table:nth-child(even) {
background: #a9edc3;
}
.table:nth-child(odd) {
background: #eda9ce;
}
.tr {
display: table-row;
}
.td {
display: table-cell;
width: 50%;
vertical-align: middle;
}
http://jsfiddle.net/herrfischerhamburg/JcVxz/
<div id="header" style="display: table-cell; vertical-align:middle;">
...
or CSS
.someClass
{
display: table-cell;
vertical-align:middle;
}
