How can I center text (horizontally and vertically) inside a div block?
Using flexbox/CSS:
<div class="box">
<p>അ</p>
</div>
The CSS:
.box{
display: flex;
justify-content: center;
align-items: center;
}
Taken from Quick Tip: The Simplest Way To Center Elements Vertically And Horizontally
Common techniques as of 2014:
Approach 1 -
transform
translateX
/translateY
:Example Here / Full Screen Example
In supported browsers (most of them), you can use
top: 50%
/left: 50%
in combination withtranslateX(-50%) translateY(-50%)
to dynamically vertically/horizontally center the element..container { position: absolute; top: 50%; left: 50%; transform: translateX(-50%) translateY(-50%); }
Approach 2 - Flexbox method:
Example Here / Full Screen Example
In supported browsers, set the
display
of the targeted element toflex
and usealign-items: center
for vertical centering andjustify-content: center
for horizontal centering. Just don't forget to add vendor prefixes for additional browser support (see example).html, body, .container { height: 100%; } .container { display: flex; align-items: center; justify-content: center; }
Approach 3 -
table-cell
/vertical-align: middle
:Example Here / Full Screen Example
In some cases, you will need to ensure that the
html
/body
element's height is set to100%
.For vertical alignment, set the parent element's
width
/height
to100%
and adddisplay: table
. Then for the child element, change thedisplay
totable-cell
and addvertical-align: middle
.For horizontal centering, you could either add
text-align: center
to center the text and any otherinline
children elements. Alternatively, you could usemargin: 0 auto
assuming the element isblock
level.html, body { height: 100%; } .parent { width: 100%; height: 100%; display: table; text-align: center; } .parent > .child { display: table-cell; vertical-align: middle; }
Approach 4 - Absolutely positioned
50%
from the top with displacement:Example Here / Full Screen Example
This approach assumes that the text has a known height - in this instance,
18px
. Just absolutely position the element50%
from the top, relative to the parent element. Use a negativemargin-top
value that is half of the element's known height, in this case --9px
.html, body, .container { height: 100%; } .container { position: relative; text-align: center; } .container > p { position: absolute; top: 50%; left: 0; right: 0; margin-top: -9px; }
Approach 5 - The
line-height
method (Least flexible - not suggested):Example Here
In some cases, the parent element will have a fixed height. For vertical centering, all you have to do is set a
line-height
value on the child element equal to the fixed height of the parent element.Though this solution will work in some cases, it's worth noting that it won't work when there are multiple lines of text - like this.
.parent { height: 200px; width: 400px; text-align: center; } .parent > .child { line-height: 200px; }
Methods 4 and 5 aren't the most reliable. Go with one of the first 3.
Add the line display: table-cell;
to your CSS content for that div.
Only table cells support the vertical-align: middle;
, but you can give that [table-cell] definition to the div...
A live example is here: http://jsfiddle.net/tH2cc/
div{
height: 90px;
width: 90px;
text-align: center;
border: 1px solid silver;
display: table-cell; // This says treat this element like a table cell
vertical-align:middle; // Now we can center vertically like in a TD
}
If it is one line of text and/or image, then it is easy to do. Just use:
text-align: center;
vertical-align: middle;
line-height: 90px; /* The same as your div height */
That's it. If it can be multiple lines, then it is somewhat more complicated. But there are solutions on http://pmob.co.uk/. Look for "vertical align".
Since they tend to be hacks or adding complicated divs... I usually use a table with a single cell to do it... to make it as simple as possible.
Update for 2020:
Unless you need make it work on earlier browsers such as Internet Explorer 10, you can use flexbox. It is widely supported by all current major browsers. Basically, the container needs to be specified as a flex container, together with centering along its main and cross axis:
#container {
display: flex;
justify-content: center;
align-items: center;
}
To specify a fixed width for the child, which is called a "flex item":
#content {
flex: 0 0 120px;
}
Example: http://jsfiddle.net/2woqsef1/1/
To shrink-wrap the content, it is even simpler: just remove the flex: ...
line from the flex item, and it is automatically shrink-wrapped.
Example: http://jsfiddle.net/2woqsef1/2/
The examples above have been tested on major browsers including MS Edge and Internet Explorer 11.
One technical note if you need to customize it: inside of the flex item, since this flex item is not a flex container itself, the old non-flexbox way of CSS works as expected. However, if you add an additional flex item to the current flex container, the two flex items will be horizontally placed. To make them vertically placed, add the flex-direction: column;
to the flex container. This is how it works between a flex container and its immediate child elements.
There is an alternative method of doing the centering: by not specifying center
for the distribution on the main and cross axis for the flex container, but instead specify margin: auto
on the flex item to take up all extra space in all four directions, and the evenly distributed margins will make the flex item centered in all directions. This works except when there are multiple flex items. Also, this technique works on MS Edge but not on Internet Explorer 11.
Update for 2016 / 2017:
It can be more commonly done with transform
, and it works well even in older browsers such as Internet Explorer 10 and Internet Explorer 11. It can support multiple lines of text:
position: relative;
top: 50%;
transform: translateY(-50%);
Example: https://jsfiddle.net/wb8u02kL/1/
To shrink-wrap the width:
The solution above used a fixed width for the content area. To use a shrink-wrapped width, use
position: relative;
float: left;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
Example: https://jsfiddle.net/wb8u02kL/2/
If the support for Internet Explorer 10 is needed, then flexbox won't work and the method above and the line-height
method would work. Otherwise, flexbox would do the job.
