newbie here starting with the basics of HTML and CSS. I really have a hard time centering a simple div (a square in my example). I've watched many tutorials as well as read many articles but still cannot really figure out the "best" way to do it. With so many different ways like align-items, align-content, justify-items, justify-content, I get overwhelmed at some point especially with how these behave with different displays (flex, grid, inline-block etc), not to mention the positions of parents and childs. Below is an example that I still can't quite easily manipulate/center. The HTML is only the boilerplate and a blank div with class square inside the body. Thank you all in advance for your tips!
html {
height: 100%;
}
body {
min-height: 100%;
background-color: #162944;
}
.square {
height: 10rem;
width: 10rem;
background-color: salmon;
display: flex;
align-items:center;
justify-items: center;
align-content: center;
justify-content:center;
place-content: center;
place-items: center;
}
The above example has been tried with all possible combinations and NOT only as you see it. Also with display:grid; and others. Is there really not a simple way to center an object on your page?
One way to center a div is to set the width of the element and then use the margin property to set the left and right margins to auto. This will horizontally center the element within its container.
For example:
.element {
width: 400px;
margin-left: auto;
margin-right: auto;
}
You can also by using the text-align property.
.shape {
text-align: center;
}
Also by using the margin property.
For example:
.shape {
margin: 0 auto;
}
Finally, you can center a div when it comes to shapes by using the transform property.
For example:
.shape {
transform: translate(50%, 50%);
}
Centering a div can be easy or hard based on your layout options and what you want to achieve.
The simplest way to horizontally center a div, add a width and margin: 0 auto.
Simplest way to horizontally and vertically center a div is using a flexbox, display: flex; justify-content:center; align-items:center. Also you can go with display:table and display:table-cell.
Last option is to use Positioning. You can take a div, style it with position:relative and add a height:300px,width:300px. Then inside the parent div, add a child div and style it with position:absolute; top:50%; left:50%; transform:translate(-50%,-50%); height:50px; width:50px

So I am trying to vertical align and horizontal a textbox span inside a parent div, the problem is it can valign or halign fine, not both. If it is a one line text it works fine, but if it is a long paragraph that takes multiple lines of the parent div, it does not vertical align.
.objprevicnt {
position: absolute;
margin: 0;
top: 50%;
left: 50%;
width:inherit;
height:50px;
transform: translate(-50%, -50%);
}
also I am changing the text dynamically
document.getElementById("myid").innerHTML = 'some text';
so it should recenter as appropriate.
You would think this would be a simple thing, vertical and horizontal centering of a box inside another box, should work regardless of the size of text inside the box.
I think these CSS properties will work. Please try this.
#parent_div{
display:flex;
align-items:center;
direction:column;
}
#child_element{
display:flex;
align-self: center;
}
The easiest way to center an element inside a parent element would probably be using flexbox:
.parent {
display: flex;
justify-content: center;
align-items: center;
}
.child {
display: block;
}
I have code to center my images (and eventually videos) like I want inside a div, but I am trying to get the images to stack vertically in a column.
It works if the space is confined enough, but I want it to work all the time. What can I do? Here is my codepen:
div{
margin: 0 auto;
height: 100vh;
text-align: center;
overflow: hidden;
max-width: 172vh;
}
img{
height: 50%;
}
https://codepen.io/thejaredmosley/pen/OJPVqBa
try below:
div {
....
display: flex;
flex-direction: column;
}
You can simply do it with the display:block CSS property.
https://www.w3schools.com/cssref/pr_class_display.asp
Give this CSS to your image and your image will get full-width space and will come in a stack.
So for Image, add this property:
img{
display:block;
}

Edit:

but i need the side div (side box) to be Vertical centered to the main div (center box)
the main pic size is not fixed (every media will have different size - so i cant use PX as position
Use CSS3 Flexbox for modern Browsers: Here's Browser support for it.
.center-both{
display: flex;
justify-content: center;
align-items: center;
height: 350px;
background: LightSeaGreen;
}
Fiddle
Read this article for more on flexbox: http://dipaksblogonline.blogspot.in/2014/05/css-flexbox-explained-with-examples.html
If you want to support old browsers like IE7/IE8 then use display: table-cell; property to place the content vertically center.
Change the css for Sidepanel class as below
.SidePanel {
width: 5%;
height: auto;
float: left;
background-color: green;
display: flex;
justify-content: center;
align-items: center;
}
Use This Code For Your Pic:
.pic{
position: absolute;
top: 50%;
margin-top: -(HEIGHT/2)
}
Which HEIGHT is Your Picture's height in Pixels.
Update 1
Your Container Should Have A Specific Height And Have A CSS Property: Position: (Relative|Absolute|Fixed)
If I'm going to center an element in the middle of the screen with flexbox, is the following approach the most elegant?
HTML
<div class='btn'></div>
CSS
body{
overflow: hidden;
position: absolute;
width: 100%;
height: 100%;
display: flex;
}
.btn{
width: 10rem;
height: 10rem;
background-color: #033649;
margin: auto;
}
It seems that I have to use position: absolute and height+weight 100% to achieve this.
You have to use position: absolute because the default for an element is position: relative, and in this case, there is nothing to be relative to because you have made the flex container the body.
Your code will work fine, but there is a command to center objects in the actual flex model itself like so:
body{
overflow: hidden;
position: absolute;
width: 100%;
height: 100%;
display: flex;
justify-content: center; /*centers items on the line (the x-axis by default)*/
align-items: center; /*centers items on the cross-axis (y by default)*/
}
If you do this you can remove the margin: auto from your .btn class to perhaps give some more wiggle room in your code.
Here is a good resource for all things flexbox.
You can position an element inside a container by using place-items without the need to add any CSS property to that element. In this case I'm using the body of document as the container.
Snippet
body{
margin:0;
height:100vh; /* use 100% of the height of the viewport */
display:grid;
place-items: center;
}
<body>
<button>I'm a lonely button :B</button>
</body>
About place-items
The CSS place-items shorthand property allows you to align items along
both the block and inline directions at once (i.e. the align-items and
justify-items properties) in a relevant layout system such as Grid or
Flexbox. If the second value is not set, the first value is also used
for it.

I want to center an object using CSS and no hacks, is this possible and how?
I have tried this, but than my p tag is gone.
.centered {
position: fixed;
top: 50%;
left: 50%;
}
There's several ways to center an element. But it depends on what your element is and how we choose to display it:
If you have {display:inline; }
This is simple. You can just use "text-align: center;" to center text, images and divs.
If you have {display:block;}
This is a bit more difficult. It depends on how your object is positioned. Your object could be relative, absolute, or fixed.
If it is relative; then you can use "margin:0 auto;", however you will require a width value.
If it is absolutely positioned, then you need to specify your "top:" and "left:" values. You'll also need a width. If you know the width of the element, the best way is to use {left:50%; margin-left:-X}, where X = 1/2 the width of the element.
HTML:
<div>Centered</div>
CSS:
div {
margin: 0 auto;
width: 200px;
}
Live example: http://jsfiddle.net/v3WL5/
Note that margin: 0 auto; will only have an effect if the div has a width.
Use margin: auto like this:
margin: 0px auto
Use this for general purposes. Even span or div which is inside whatever :
width:inherit; display:block;margin:0 auto;
Usage :
In-Line usage : Content goes
here....
CSS Code :
#text-align
{
text-align:center
}
HTML Code :
<div id="text-align">Content goes here....</div>

late into the game, but have you tried with display:flex on the parent ?
I have a useful class that is simple and works with all type of elements:
/* apply this on the parent */
.center {
display:flex;
align-items: center; /*vertical alignement*/
justify-content: center; /* horizontal alignement*/
}
This is relatively new but supported at ~98% of major browsers.
However I suggest that you learn a bit about flexBox, it may seem complicated at first but it is very powerful for all type layouts !
if you don't need to be position:fixed; you can just use
<center>
