css div设置margin:0 auto不能水平居中

Jun 01, 2016 am 09:53 AM
css margin center Center horizontally

站长在这里跟大家分析一下margin:0 auto不能水平居中的原因:

  1. margin:0 auto居中的前提是我们为div设置了宽度,如果没有设置宽度,就算使用了改css属性,也不会取作用。因此,首先要检查一下是否设置宽度。
  2. 检查一下div是否使用了float:left或float:right,如果使用了float:left或float:right,margin:0 auto也不会取作用。

实例:

<code class="html"> 
 
 
<title>css 解决div设置margin:0 auto不能水平居中的方法</title> 

 
 
<div style="margin:0 auto;">码农教程</div>
<!--如果不设置宽度,div无法居中。-->
<div style="margin:0 auto;width:300px;">码农教程</div>
<!--这样设置即可居中-->
