DIV CSS 佈局教程網

1、單行垂直居中
 
文字在層中垂直居中vertical-align 屬性是做不到的.我們這裡有個比較巧妙的方法就是:設置height的高度與line-height的高度相同!
 

<div style="line-height:500px;height:500;"></div>
 

2、層水平居中
 
設置div的寬度小於父div的寬度，設置 margin:0 auto;，即可讓div居中。
 

#parentdiv
 {
 width: 500px;
 }
 #childdiv {
 width: 200px;
 margin:0 auto;
 }
 

3、層中的文字水平居中
 
在childdiv的css加上text-align:center;
 

#parentdiv
 {
 width: 500px;
 }
 #childdiv {
 width: 200px;
 margin:0 auto;
 text-align:center;
 }
 

4、div層垂直居中
 

<div style="width:275px;height:375px;border: solid red;">
 <div style=" background:green;height: 375px; width: 275px; position: relative; display: table-cell; vertical-align: middle;">
      <div style=" background:red;position:static;position:absolute\9; top: 50%;">
         <div style=" background:blue;position: relative; top: -50%;">
