I want to place a div (with position:absolute;) element in the center of the window. But I'm having problems doing so, because the width is unknown.
I tried the following CSS code, but it needs to be adjusted because the width is responsive.
.center {
left: 50%;
bottom: 5px;
}
How can I achieve this?
This works for me:
#content {
position: absolute;
left: 0;
right: 0;
margin-left: auto;
margin-right: auto;
width: 100px; /* Need a specific value to work */
}
<body>
<div>
<div id="content">
I'm the content
</div>
</div>
</body>
<body>
<div style="position: absolute; left: 50%;">
<div style="position: relative; left: -50%; border: dotted red 1px;">
I am some centered shrink-to-fit content! <br />
tum te tum
</div>
</div>
</body>
Responsive Solution
Here is a good solution for responsive design or unknown dimensions in general if you don't need to support IE8 and lower.
.centered-axis-x {
position: absolute;
left: 50%;
transform: translate(-50%, 0);
}
.outer {
position: relative; /* or absolute */
/* unnecessary styling properties */
margin: 5%;
width: 80%;
height: 500px;
border: 1px solid red;
}
.inner {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
/* unnecessary styling properties */
max-width: 50%;
text-align: center;
border: 1px solid blue;
}
<div class="outer">
<div class="inner">I'm always centered<br/>doesn't matter how much text, height or width i have.<br/>The dimensions or my parent are irrelevant as well</div>
</div>
Here is a JS Fiddle
The clue is, that left: 50% is relative to the parent while the translate transform is relative to the elements width/height.
This way you have a perfectly centered element, with a flexible width on both child and parent. Bonus: this works even if the child is bigger than the parent.
You can also center it vertically with this (and again, width and height of parent and child can be totally flexible (and/or unknown)):
.centered-axis-xy {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%,-50%);
}
Keep in mind that you might need transform vendor prefixed as well. For example -webkit-transform: translate(-50%,-50%);
<div style='position:absolute; left:50%; top:50%; transform: translate(-50%, -50%)'>
This text is centered.
</div>
This will center all the objects inside div with position type static or relative.
I just wanted to add if someone wants to do it with a single div tag then here is the way out:
Taking width as 900px.
#styleName {
position: absolute;
left: 50%;
width: 900px;
margin-left: -450px;
}
In this case one should know the width beforehand.
Responsive solution
Assuming the element in the div, is another div...
This solution works fine:
<div class="container">
<div class="center"></div>
</div>
The container can be any size (must be position relative):
.container {
position: relative; /* Important */
width: 200px; /* Any width */
height: 200px; /* Any height */
background: red;
}
The element (div) can also be any size (must be smaller than the container):
.center {
position: absolute; /* Important */
top: 50%; /* Position Y halfway in */
left: 50%; /* Position X halfway in */
transform: translate(-50%,-50%); /* Move it halfway back(x,y) */
width: 100px; /* Any width */
height: 100px; /* Any height */
background: blue;
}
The result will look like this. Run the code snippet:
.container {
position: relative;
width: 200px;
height: 200px;
background: red;
}
.center {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
width: 100px;
height: 100px;
background: blue;
}
<div class="container">
<div class="center"></div>
</div>
I found it very helpful.
Absolute Centre
HTML:
<div class="parent">
<div class="child">
<!-- content -->
</div>
</div>
CSS:
.parent {
position: relative;
}
.child {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
margin: auto;
}
Demo:
http://jsbin.com/rexuk/2/
It was tested in Google Chrome, Firefox, and Internet Explorer 8.
This works for vertical and horizontal:
#myContent{
position: absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
margin: auto;
}
And if you want make an element center of the parent, set the position of the parent relative:
#parentElement{
position: relative
}
For vertical center align, set the height to your element. Thanks to Raul.
If you want make an element center of the parent, set the position of the parent to relative
If you need to center horizontally and vertically too:
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
Searching for a solution, I got the previous answers and could make content centered with Matthias Weiler's answer, but using text-align:
#content{
position: absolute;
left: 0;
right: 0;
text-align: center;
}
It worked with Google Chrome and Firefox.
I understand this question already has a few answers, but I've never found a solution that would work in almost all classes that also makes sense and is elegant, so here's my take after tweaking a bunch:
.container {
position: relative;
}
.container .cat-link {
position: absolute;
left: 50%;
top: 50%;
transform: translate3d(-50%,-50%,0);
z-index: 100;
text-transform: uppercase; /* Forces CSS to treat this as text, not a texture, so no more blurry bugs */
background-color: white;
}
.color-block {
height: 250px;
width: 100%;
background-color: green;
}
<div class="container">
<a class="cat-link" href="">Category</a>
<div class="color-block"></div>
</div>
It is saying give me a top: 50% and a left: 50%, then transform (create space) on both the X/Y axis to the -50% value, in a sense "create a mirror space".
As such, this creates an equal space on all the four points of a div, which is always a box (has four sides).
This will:
Work without having to know the parent's height / width.
Work on responsive.
Work on either X or Y axis. Or both, as in my example.
I can't come up with a situation where it doesn't work.
Flexbox can be used to center an absolute positioned div.
display: flex;
align-items: center;
justify-content: center;
.relative {
width: 275px;
height: 200px;
background: royalblue;
color: white;
margin: auto;
position: relative;
}
.absolute-block {
position: absolute;
height: 36px;
background: orange;
padding: 0px 10px;
bottom: -5%;
border: 1px solid black;
}
.center-text {
display: flex;
justify-content: center;
align-items: center;
box-shadow: 1px 2px 10px 2px rgba(0, 0, 0, 0.3);
}
<div class="relative center-text">
Relative Block
<div class="absolute-block center-text">Absolute Block</div>
</div>
This is a mix of other answers, which worked for us:
.el {
position: absolute;
top: 50%;
margin: auto;
transform: translate(-50%, -50%);
}
This works on any random unknown width of the absolute positioned element you want to have in the centre of your container element:
Demo
<div class="container">
<div class="box">
<img src="https://picsum.photos/200/300/?random" alt="">
</div>
</div>
.container {
position: relative;
width: 100%;
}
.box {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
display: flex;
justify-content: center;
align-items: center;
}
It's possible to center an element that has aspect-ratio:1 with position absolute by using calc()
In the following example I'm using a circle because it's easier to explain and understand, but the same concept can be applied to any shape with aspect-ratio:1 meaning that the width and height are equal. (about aspect-ratio)
:root{
--diameter: 80px;
}
div{
position:absolute;
top: calc(50% - var(--diameter)/2);
right:calc(50% - var(--diameter)/2);
aspect-ratio:1;
width:var(--diameter);
border-radius:100%;
background:blue;
}
<div/>
Explanation
As far as I know, this is impossible to achieve for an unknown width.
You could - if that works in your scenario - absolutely position an invisible element with 100% width and height, and have the element centered in there using margin: auto and possibly vertical-align. Otherwise, you'll need JavaScript to do that.
I'd like to add on to bobince's answer:
<body>
<div style="position: absolute; left: 50%;">
<div style="position: relative; left: -50%; border: dotted red 1px;">
I am some centered shrink-to-fit content! <br />
tum te tum
</div>
</div>
</body>
Improved: /// This makes the horizontal scrollbar not appear with large elements in the centered div.
<body>
<div style="width:100%; position: absolute; overflow:hidden;">
<div style="position:fixed; left: 50%;">
<div style="position: relative; left: -50%; border: dotted red 1px;">
I am some centered shrink-to-fit content! <br />
tum te tum
</div>
</div>
</div>
</body>
Just wrap your content with a new div and use display flex and then use align-items: center; and justify-content: center; take a look...
<div class="firstPageContainer">
<div class="firstPageContainer__center"></div>
</div>
.firstPageContainer{
display: flex;
width: 1000px;
height: 1000px;
justify-content: center;
align-items: center;
background-color: #FF8527;
}
.firstPageContainer__center{
position:absolute;
width: 50px;
height: 50px;
background-color: #3A4147;
}
Sass/Compass version of a previous responsive solution:
#content {
position: absolute;
left: 50%;
top: 50%;
#include vendor(transform, translate(-50%, -50%));
}
This worked for me:
<div class="container><p>My text</p></div>
.container{
position: absolute;
left: 0;
right: 0;
margin-left: auto;
margin-right: auto;
}
My preferred centering method:
position: absolute;
margin: auto;
width: x%
absolute block element positioning
margin auto
same left/right, top/bottom
A JSFiddle is here.
Here's a useful jQuery plugin to do this. I found it here. I don't think it's possible purely with CSS.
/**
* #author: Suissa
* #name: Absolute Center
* #date: 2007-10-09
*/
jQuery.fn.center = function() {
return this.each(function(){
var el = $(this);
var h = el.height();
var w = el.width();
var w_box = $(window).width();
var h_box = $(window).height();
var w_total = (w_box - w)/2; //400
var h_total = (h_box - h)/2;
var css = {"position": 'absolute', "left": w_total + "px", "top":
h_total + "px"};
el.css(css)
});
};
#container
{
position: relative;
width: 100%;
float: left
}
#container .item
{
width: 50%;
position: absolute;
margin: auto;
left: 0;
right: 0;
}
HTML:
<div id='parent'>
<div id='child'></div>
</div>
CSS:
#parent {
display: table;
}
#child {
display: table-cell;
vertical-align: middle;
}
I know I already provided an answer, and my previous answer, along with others given, work just fine. But I have used this in the past and it works better on certain browsers and in certain situations. So I thought I'd give this answer as well. I did not "Edit" my previous answer and add it because I feel this is an entirely separate answer and the two I have provided are not related.
The accepted solution of this question didn't work for my case...

This solution works if the element has width and height
.wrapper {
width: 300px;
height: 200px;
background-color: tomato;
position: relative;
}
.content {
width: 100px;
height: 100px;
background-color: deepskyblue;
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
margin: auto;
}
<div class="wrapper">
<div class="content"></div>
</div>
.center {
position: absolute
left: 50%;
bottom: 5px;
}
.center:before {
content: '';
display: inline-block;
margin-left: -50%;
}
This is a trick I figured out for getting a DIV to float exactly in the center of a page. It is really ugly of course, but it works in all browsers.

This and more examples here.
My layout consists of 3 DIVs
The first DIVis a wrapper.
The second DIV is centered and uses max-width:980px; Otherwise it defaults to 100% width.
The third DIV is 200px wide and uses absolute position. right:-200pxand top:0px position it next to the first DIV
This layout works perfect but only because the last DIVhas a width of 200px. If that DIV had a variable width I couldn't use right:-200px and it wouldn't place correctly.
So my question is what would I do if the DIV with absolute position had a variable width? How would I place it next to the main DIV?
Here is my code.
<div class="outer_container">
<div class="internal_alignment">
<div class="main_container"></div>
<div class="column_outside"></div>
</div>
</div>
CSS
.outer_container {
overflow: hidden;
position: relative;
}
.internal_alignment {
position: relative;
max-width: 980px;
margin: 0px auto;
}
.main_container {
height: 500px;
background-color: bisque;
}
.column_outside {
position: absolute;
top: 0px;
right: -200px;
height: 500px;
width: 200px;
background-color: black;
}
FYI: the outer_container DIV allows column_outside to sit outside the screen if the browser is smaller than 980px wide.
Make it a child of the main and give it left: 100%;
.outer_container {
overflow: hidden;
position: relative;
}
.internal_alignment {
position: relative;
max-width: 980px;
margin: 0px auto;
}
.main_container {
height: 500px;
background-color: bisque;
}
.column_outside {
position: absolute;
top: 0px;
left: 100%;
height: 500px;
width: 200px;
background-color: black;
}
<div class="outer_container">
<div class="internal_alignment">
<div class="main_container">
<div class="column_outside"></div>
</div>
</div>
</div>
After a second thought, simply use left: 100% instead of right: -200px;
.outer_container {
overflow: hidden;
position: relative;
}
.internal_alignment {
position: relative;
max-width: 980px;
margin: 0px auto;
}
.main_container {
height: 500px;
background-color: bisque;
}
.column_outside {
position: absolute;
top: 0px;
left: 100%;
height: 500px;
width: 200px;
background-color: black;
}
<div class="outer_container">
<div class="internal_alignment">
<div class="main_container"></div>
<div class="column_outside"></div>
</div>
</div>
Very simple:
.column_outside {
right: 0px;
-webkit-transform: translateX(100%);
-moz-transform: translateX(100%);
transform: translateX(100%);
}
Demo https://jsfiddle.net/n4nq6Lxt/
No need to change your HTML structure.
You can use transform: translateX(100%); what it does is to move the element to the right of the amount of the width of the element itself.
right: 0;
transform: translateX(100%);
As you can see from this fiddle:

I'm through a problem that I've never been before. I'm working with Drupal CMS and it generates a lot of the markup you need to style.
Given the use case, I have a MODAL box that are wrapped into a lot of divs and, like all MODALS, it need to be FIXED positioned. But, when I do this, the behavior is very much like absolute positioning. It get stuck in place and inherit all the .wrap div dimensions.
Thanks for the help.
Edit
The code:
HTML
<header class="sticky">log and menu</header>
<main>
<section class="test">
<div class="wrap">
<div class="myEl">
<!--HERE BE SOME SCROLLABLE ELEMENTS-->
<div.class="iWannaBeScrollable">i'm scrollable</div>
<!--HERE BE THE FIXED ONE-->
<div class="modal">as you can see, this should be FIXED, but appears to be stuck into the parent.</div>
</div>

}
}
}
}
Why is there
transform: translateX(-50%);
on the .wrap element?
I think thats causing your problem...
IIRC: In my Drupal days, anytime you needed to fix an element, you wanted to call the top most parent.
So in this case, you would want to apply postioned:fixed it to .wrap.
.wrap{
position:fixed;
}
Here's why:
You are styling Modal with the fixed, so it is staying fixed within it's parent. You're parent/grandparent is styled as position:relative. Which makes .wrap and .myEl scrollable, while the modal is fixed within the scrollable div.
This makes it appear as if it is position:absolute;

A couple of problems with your code:
You do not have a width and height specified on your html and body, without which any of descendent elements wouldn't have a reference to set their positions and/or dimensions in percent units.
You do not have dimensions (width/height) specified on your #div_parent, without which you cannot position its absolutely positioned child (which is relative to it) to the vertical center. Moreover, as you want to position your .div_child to the center of the page, why do you have a parent wrapped around it anyway.
Apart from fixing the above, a trick which is usually used to align elements both horizontally and vertically is to use transform: translate to shift it back by 50%.
Like this:
.div_child {
position: absolute; left: 50%; top: 50%;
transform: translate(-50%, -50%);
...
}

Hope it works for you.
I need an image to be resized to fit in inside a div. This div must, necessarely, no matter what, be an position: absolute; div. Apart from the image have 100% from its greatest dimension, it should be centered in the other way.
I could resize to fit it, but can't center. I tried to make it inline and use vertical-align, but it didn't work.
Since code worth more than words, check my fiddle example.
This is the code from the jsfiddle:

.absolute {
background-image: url(http://upload.wikimedia.org/wikipedia/commons/1/15/Cat_August_2010-4.jpg);
background-repeat: no-repeat;
background-position: center;
background-size: contain;
}
however, if you can set a fixed height for the div, you can use this:
.absolute { line-height:360px; }
.absolute img { vertical-align:middle; }
Only for semi-new browsers:
img {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}
Absolutely position all the things!
transform still needs browser prefixes I hear. -webkit- works for me.

Maybe I did not understand the question…
.absolute {
position: absolute;
top: 20px;
bottom: 20px;
left: 20px;
right: 20px;
background-color: red;
line-height:350px; //new
}
img {
position:relative;
display:inline-block; // new
vertical-align:middle; // new
max-width: 100%;
max-height: 100%;
width: auto;
height: auto;
}
