Center text in div? | 易学教程

问题

I have a div 30px high and 500px wide. This div can contain two lines of text one under the other, and is styled (padded) accordingly. But sometimes it only contains one line, and I want it to be centered. Is this possible?

回答1:

To center horizontally, use text-align:center.

To center vertically, one can only use vertical-align:middle if there is another element in the same row that it is being aligned to.
See it working here.

We use an empty span with a height of 100%, and then put the content in the next element with a vertical-align:middle.

There are other techniques such as using table-cell or putting the content in an absolutely positioned element with top, bottom, left, and right all set to zero, but they all suffer from cross browser compatibility issues.

回答2:

I believe you want the text to be vertically centered inside your div, not (only) horizontally. The only reliable way I know of doing this is using:

display: table-cell;
vertical-align: middle;

on your div, and it works with any number of lines. You can see a test here: http://jsfiddle.net/qMtZV/1/

Be sure to check browser support of this property, as it is not supported — for example — in IE7 or earlier.

UPDATE 02/10/2016

Five years later this technique is still valid, but I believe there are better and more solid solutions to this problem. Since Flexbox support is good nowadays, you might want to do something along these lines: http://codepen.io/michelegera/pen/gPZpqE.

HTML

<div class="outside">
  <div class="inside">
      <p>Centered Text</p>
  </div>
</div>

CSS

.outside { 
  position: absolute; 
  display: table; 
}

.inside {
  display: table-cell; 
  vertical-align: middle; 
  text-align: center; 
}

If you have text inside a <div>:

text-align: center;
vertical-align: middle;
display: table-cell;

回答5:

For the parent div,use following CSS:

style="display: flex;align-items: center;"

回答6:

div {
    height: 256px;
    width: 256px;
    display: table-cell;
    text-align: center;
    line-height: 256px;
}

The trick is to set the line-height equal to the height of the div.

回答7:

Adding line height helps too.

text-align: center;
line-height: 18px; /* for example. */

回答8:

I may be missing something here, but have you tried:

text-align:center;

回答9:

You may try to use in your CSS the property vertical-align in order to center it verticaly

div {  
    vertical-align:middle;  
}

if it's a size problem, please notice that 2 text lines and a padding style have great chance to have a height superior to 30px.

For example, if your font size is 12 px and your div padding is 5 px, a one text line div height will be 5px (padding-top) + 12px + 5 px (padding-bottom) = 22px < 30px so no problem,

With a 2 text lines div, it will be 5px +12px *2 (2 lines) + 5px = 34px > 30px and your div height will be automatically changed.

Try either to increase your div height (maybe 40px) or to reduce your padding.

Hope it will help

Will this work for you?

div { text-align: center; }

回答11:

I've looked around and the

display: table-cell;
vertical-align: middle;

seems to be the most popular solution

回答12:

display: block;
text-align: center;

回答13:

Add to the selector containing the text

margin:auto;
