1、单行垂直居中
文字在层中垂直居中vertical-align 属性是做不到的.我们这里有个比较巧妙的方法就是:设置height的高度与line-height的高度相同!
<div style="line-height:500px;height:500;"></div>
2、层水平居中
设置div的宽度小于父div的宽度,设置 margin:0 auto;,即可让div居中。
#parentdiv
{
width: 500px;
}
#childdiv {
width: 200px;
margin:0 auto;
}
3、层中的文字水平居中
在childdiv的css加上text-align:center;
#parentdiv
{
width: 500px;
}
#childdiv {
width: 200px;
margin:0 auto;
text-align:center;
}
4、div层垂直居中
<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%;">

      </div>
   </div>
</div>
5、div层垂直水平居中,英文超长换行
   <div style="float:left;width:275px;height:375px;border: solid red;">
<div style=" height: 375px; width: 275px; position: relative; display: table-cell; vertical-align: middle;">
          <div style="position:static;position:absolute\9; top: 50%;">
           <div style="position: relative; top: -50%; text-align: center;">
              <div style="width: 85px;WORD-WRAP: break-word;TABLE-LAYOUT: fixed;word-break:break-all;margin:0 auto;">
              </div>              
              </div>
          </div>
         </div>
</div>
6、div垂直滚动
<div style="width: 160px; height: 260px; overflow-y: scroll; border: 1px solid;">http://www.51xuedeiannao.com </div>
7、垂直居中和使用text-align水平居中
<div style="float:left;width:275px;height:375px;border: solid red;">
<div style=" height: 375px; width: 275px; position: relative; display: table-cell; vertical-align: middle;">
          <div style="position:static;position:absolute\9;top: 50%;">
           <div style="position: relative; top: -50%; text-align:center;">
            <div style="width: 275px;">
                      <div style="width: 160px;WORD-WRAP: break-word;TABLE-LAYOUT: fixed;word-break:break-all;text-align:left;">
              </div>
              </div>
              </div>
          </div>
         </div>
</div>
8、垂直居中和使用margin水平居中
    <div style="float:left;width:275px;height:375px;border: solid red;">
<div style=" height: 375px; width: 275px; position: relative; display: table-cell; vertical-align: middle;">
          <div style="position:static;position:absolute\9; top: 50%;">
           <div style="position: relative; top: -50%; ">
            
                      <div style="margin:0 auto;width: 160px;WORD-WRAP: break-word;TABLE-LAYOUT: fixed;word-break:break-all;">
              </div>
              </div>
          </div>
         </div>
</div>
