有两个div:


  

  



div1的大小是动态的,我想让div2在div1中垂直居中,
用css怎么写?

回复讨论(解决方案)

line-height和 height的值设置成相同的即可

line-height和 height的值设置成相同的即可
设置div1的line-height?

#div1{ display:table-cell;vertical-align:middle;}

 #div1 {            border-top:1px solid;            border-bottom:1px solid;            color:transparent;            /**/            background-color:#eee;                                       }        #div2 {            background-color:#ccc;            color:#000;            margin-top:10px;            margin-bottom:10px;        }


模拟单元格也是好办法。

动态的,必须用js,单纯的css实现不了

#div1{ display:table-cell;vertical-align:middle;}


这个可行,但是用了display:table-cell之后
margin不起作用了 靠左
请教怎么解决


#div1{ display:table-cell;vertical-align:middle;}

试过用固定定位 absolute 
可是display:table-cell效果就没有了

还是用js吧


#div1{ display:table-cell;vertical-align:middle;}

外层在套一个DIV来控制间隔
<style>      #div1{ display:table-cell;vertical-align:middle;}      .inner{ margin:10px;}</style><div class="inner"><div id="div1">  <div id="div2">  </div></div></div>



#div1{ display:table-cell;vertical-align:middle;}

效果出来了
另外还想探讨下
为了做出这种效果用了多个div
是否会繁琐

如果单纯只是这样的话,直接对div加一个padding不就可以了?

设置div2的css
 #div2 {
       width:***px;
       margin:0 auto;
}
就可以了

学习下.学这个头大

额,我是新手,没太看懂,为什么不用

呢?

 html5中已经去掉了

单纯用CSS控制垂直居中挺难的,我试过写,但是效果不好,要做到多浏览器兼容的垂直居中效果,还是建议用JS写

CSS未知高度div 垂直居中的问题
这个问题我碰过。可以用上面的方法解决。

呢?

貌似只有IE内核浏览器支持,火狐就不支持这种写法。

其实我一直用chrome做测试,center是ok的,不过刚刚查了html5手册,果然是要删,只好另寻办法了。。。

div1中加入 vertical-align:middle

Boolean attributes are special attributes in HTML that are activated without a value. 1.

The basic usage is to directly add attributes, and the advanced usage can be dynamically controlled through JavaScript. 4. Common mistakes are mistakenly thinking that values ​​need to be set, and the correct writing method should be concise. 5. The best practice is to keep the code concise and use Boolean properties reasonably to optimize web page performance and user experience.
