How can I vertically center a div element for all browsers using CSS?
Below is the best all-around solution I could build to vertically and horizontally center a fixed-width, flexible height content box. It was tested and worked for recent versions of Firefox, Opera, Chrome, and Safari.
.outer {
display: table;
position: absolute;
top: 0;
left: 0;
height: 100%;
width: 100%;
}
.middle {
display: table-cell;
vertical-align: middle;
}
.inner {
margin-left: auto;
margin-right: auto;
width: 400px;
/* Whatever width you want */
}
<div class="outer">
<div class="middle">
<div class="inner">
<h1>The Content</h1>
<p>Once upon a midnight dreary...</p>
</div>
</div>
</div>
Css vertically center explained
position: absolute
takes an element out of the document flow and lets you position it in relation to the next higher ancestor which has position: relative
, usually (and intentionally) overlapping other elements (for example text over an image).
top: 50%
moves the top of the absolutely positioned element 50% down, i.e. half of the parent's height. That way the top border of the child element will be at the exact center of the parent.
transform: translateY(-50%);
moves the absolutely positioned element 50% up, but this time 50% of its own height, above the vertical center of the parent element, resulting in exact vertical centering inside the parent.
All this only works if the parent has position: relative
, so it can serve as a position anchor for the absolutely positioned child.
The same goes for horizontal centering, using left: 50%
and transform: translateX(-50%);
Combined (i.e. horizontally and vertically) that would be top: 50%; left: 50%
and transform: translate(-50%, -50%);
CSS center and vertical alignment
You will need to add height: 100%
to all the parent elements for the vertical alignment inside the entire page. Currently the row only occupies the content height and is vertically aligned according to the content height.
html, body, .row {
height: 100%;
}
.row {
display:flex;
justify-content: center;
align-items: center;
}

How to vertically align an image inside a div
The only (and the best cross-browser) way as I know is to use an inline-block
helper with height: 100%
and vertical-align: middle
on both elements.
So there is a solution: http://jsfiddle.net/kizu/4RPFa/4570/
.frame { height: 25px; /* Equals maximum image height */ width: 160px; border: 1px solid red; white-space: nowrap; /* This is required unless you put the helper span closely near the img */
text-align: center; margin: 1em 0;}
.helper { display: inline-block; height: 100%; vertical-align: middle;}
img { background: #3A6F9A; vertical-align: middle; max-height: 25px; max-width: 160px;}
<div class="frame"> <span class="helper"></span><img src="http://jsfiddle.net/img/logo.png" height=250px /></div><div class="frame"> <span class="helper"></span><img src="http://jsfiddle.net/img/logo.png" height=25px /></div><div class="frame"> <span class="helper"></span><img src="http://jsfiddle.net/img/logo.png" height=23px /></div><div class="frame"> <span class="helper"></span><img src="http://jsfiddle.net/img/logo.png" height=21px /></div><div class="frame"> <span class="helper"></span><img src="http://jsfiddle.net/img/logo.png" height=19px /></div><div class="frame"> <span class="helper"></span> <img src="http://jsfiddle.net/img/logo.png" height=17px /></div><div class="frame"> <span class="helper"></span> <img src="http://jsfiddle.net/img/logo.png" height=15px /></div><div class="frame"> <span class="helper"></span> <img src="http://jsfiddle.net/img/logo.png" height=13px /></div><div class="frame"> <span class="helper"></span> <img src="http://jsfiddle.net/img/logo.png" height=11px /></div><div class="frame"> <span class="helper"></span> <img src="http://jsfiddle.net/img/logo.png" height=9px /></div><div class="frame"> <span class="helper"></span> <img src="http://jsfiddle.net/img/logo.png" height=7px /></div><div class="frame"> <span class="helper"></span> <img src="http://jsfiddle.net/img/logo.png" height=5px /></div><div class="frame"> <span class="helper"></span> <img src="http://jsfiddle.net/img/logo.png" height=3px /></div>
How can I vertically align elements in a 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 itsheight
,margin-top
andtop
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.
- If the inner element can have a fixed height, you can make its position
Vertical Align Center in Bootstrap 4
Important! Vertical center is relative to the height of the parent
If the parent of the element you're trying to center has no defined
height, none of the vertical centering solutions will work!
Now, onto vertical centering...
Bootstrap 5 (Updated 2021)
Bootstrap 5 is still flexbox based so vertical centering works the same way as Bootstrap 4. For example, align-items-center
, justify-content-center
or auto margins can used on the flexbox parent (row
or d-flex
).
- use
align-items-center
on a flexbox row parent (row
ord-flex
) - use
justify-content-center
on a flexbox column parent (d-flex flex-column
) - use
my-auto
on a flexbox parent
Vertical Center in Bootstrap 5
Bootstrap 4
You can use the new flexbox & size utilities to make the container
full-height and display: flex
. These options don't require extra CSS (except that the height of the container (ie:html,body) must be 100%).
Option 1 align-self-center
on flexbox child
<div class="container d-flex h-100">
<div class="row justify-content-center align-self-center">
I'm vertically centered
</div>
</div>
https://codeply.com/go/fFqaDe5Oey
Option 2 align-items-center
on flexbox parent (.row
is display:flex; flex-direction:row
)
<div class="container h-100">
<div class="row align-items-center h-100">
<div class="col-6 mx-auto">
<div class="jumbotron">
I'm vertically centered
</div>
</div>
</div>
</div>

Option 3 justify-content-center
on flexbox parent (.card
is display:flex;flex-direction:column
)
<div class="container h-100">
<div class="row align-items-center h-100">
<div class="col-6 mx-auto">
<div class="card h-100 border-primary justify-content-center">

More on Bootstrap 4 Vertical Centering
Now that Bootstrap 4 offers flexbox and other utilities, there are many approaches to vertical
alignment. http://www.codeply.com/go/WG15ZWC4lf
1 - Vertical Center Using Auto Margins:
Another way to vertically center is to use my-auto
. This will center the element within it's container. For example, h-100
makes the row full height, and my-auto
will vertically center the col-sm-12
column.
<div class="row h-100">
<div class="col-sm-12 my-auto">
<div class="card card-block w-25">Card</div>
</div>
</div>
Vertical Center Using Auto Margins Demo
my-auto
represents margins on the vertical y-axis and is equivalent to:
margin-top: auto;
margin-bottom: auto;
2 - Vertical Center with Flexbox:
Since Bootstrap 4 .row
is now display:flex
you can simply use align-self-center
on any column to vertically center it...
<div class="row">
<div class="col-6 align-self-center">
<div class="card card-block">
Center
</div>
</div>
<div class="col-6">
<div class="card card-inverse card-danger">
Taller
</div>
</div>
</div>
or, use align-items-center
on the entire .row
to vertically center align all col-*
in the row...
<div class="row align-items-center">
<div class="col-6">
<div class="card card-block">
Center
</div>
</div>
<div class="col-6">
<div class="card card-inverse card-danger">
Taller
</div>
</div>
</div>

3 - Vertical Center Using Display Utils:
Bootstrap 4 has display utils that can be used for display:table
, display:table-cell
, display:inline
, etc.. These can be used with the vertical alignment utils to align inline, inline-block or table cell elements.
<div class="row h-50">
<div class="col-sm-12 h-100 d-table">
<div class="card card-block d-table-cell align-middle">
I am centered vertically
</div>
</div>
</div>

Important! Did I mention height?
Remember vertical centering is relative to the height of the parent element. If you want to center on the entire page, in most cases, this should be your CSS...
body,html {
height: 100%;
}
Or use min-height: 100vh
(min-vh-100
in Bootstrap 4.1+) on the parent/container. If you want to center a child element inside the parent. The parent must have a defined height.

Vertical center when using flex
Simply add .thing { display: flex; flex-direction: column; justif-content: center; }
to the CSS. flex-direction: column;
will make sure that the normal block-level element behavior is maintained. justify-content: center;
aligns the items at the cenetr of the main-axis (in this case the vertical axis).
.container {
height: 100vh;
width: 100vw;
display: flex;
flex-wrap: wrap;
}
.thing {
background: red;
color: white;
margin: 5px;
text-align: center;
flex: 1 0 30%;
display: flex;
flex-direction: column;
justify-content: center;
}
