I saw an article in W3CPlus a few days ago, which mentioned using CSS to create horizontal and vertical centering. When testing the sixth point, I found some small problems:

Add A meaningless new tag

<div id="extra">

When setting the content width, the text wraps

For the first point, the solution is to use: before pseudo-element:

 1 <!doctype html> 2 <html> 3 <head> 4 <meta charset="utf-8"> 5 <title>水平垂直居中</title> 6 <style> 7 .wrapper { 8     width: 200px; 9     height: 200px;10     background: skyblue;11 }12 .wrapper:before {13     content: '.';14     display: inline-block;15     vertical-align: middle;16     height: 100%;17 }18 .content {19     display: inline-block;20     text-align: center;21 }22 </style>23 </head>24 25 <body>26 <div class="wrapper">27   <div class="content">多行文字居中 多行文字居中 多行文字居中 </div>28 </div>29 </body>30 </html>

Demo attached

But! Everyone has also noticed: the text is wrapped

This is the gap caused by the inline-block causing trouble

In order to solve this problem, you can try this hack:

1 .wrapper {2 font-size:03 }4 5 .content {6 font-size:16px7 }

Save and look again:

Done!
