如何解决IE6/IE7不识别display:inline-block属性

如何解决IE6/IE7不识别display:inline-block属性
ie6,ie7的haslayout属性是个让人头疼的问题。在做导航条的时候,一般会用到ul li结构,大多数时候我们是把li设置为浮动,让其并排显示在同一行。还有一种方法就是设置li为display:inline;这样可以达到同样的效果,但是问题是inline元素的特性:默认无法设置宽度,高度,以及上下margin,(关于padding,情况有点特殊,在ie6,7中 inline元素是无法设置上下padding的,但是在标准浏览器里面是可以设置上下padding的)。

鉴于inline元素的这种特性,如果我们不浮动并且想让li显示在一行,而且可以设置高度,宽度以及上下margin,上下padding等属性,应该怎么办呢?你一定会想到一个属性display:inline-block;对!inline- block就是干这个事的,让一个元素既不换行又具有block元素的特性。不过有点小问题.

在IE6、IE7中不识别display:inline-block属性,加不加display:inline-block;对于它们完全没有任何影响。那么让我们来想办法解决这个问题,这就涉及到ie6,7中的haslayout属性了。ie6,7中的inline元素有个特殊的情况,就是触发了ie的hasLayout属性以后就拥有了layout。此时inline元素的表现和标准浏览器里面的inline-block元素基本相同。

看下面这个例子,我们用ie的私有属性zoom来触发hasLayout,然后看看inline元素的表现。

复制代码代码如下:
html xmlns=http://imgbuyun.weixiu-service.com/up79/202210/d3fkcucd0rg head meta http-equiv=Content-Type content=text/html; charset=utf-8 /
titledisplay-block/title
style
span {
width:200px;
height:50px;
margin:10px;
padding:20px;
background:#ccc;
zoom:1;
/style
/head
body
spanspan style="font-family:宋体,微软雅黑,Verdana,Helvetica"span/span /span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"/body /span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"/html/span

可以看到在ie6,7中inline元素span已经表现得和一个display:inline-block元素一摸一样了,但是在标准浏览器中span仍然是行内元素(宽高以及上下margin都无效)。
如果声明了不正确DTD,导致ie6在quirks 模式下解析,那么ie6会自动触发inline元素的haslayout,不过这里只讨论正常情况下的解析,所以加了个zoom:1来触发haslayout;zoom的值设置为除了auto外的任何值都会触发haslayout,之所以经常用zoom:1;是因为zoom这个属性本身是ie的缩放属性,设置为其他值会导致元素在ie下变形,设置为1既是保持原形不缩放。
了解了上面的情况,我们就可以来解决之前那个问题了。可以改原先的css代码如下:

复制代码代码如下:
li span style="font-family:宋体,微软雅黑,Verdana,Helvetica"{/span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"display:inline-block; /* firefox等标准浏览器识别*/ /span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"*display:inline; /* 只有ie6和ie7识别*/zoom:1; /* 触发ie6和ie7下的haslayout */ /span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"width:80px; /span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"height:20px; /span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"margin:10px; /span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"padding:10px; /span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"text-align:center; /span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"background:#cfc; /span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"}/span
span style="font-family:宋体,微软雅黑,Verdana,Helvetica"span style="color:rgb(17,17,17); font-family:宋体,微软雅黑,Verdana,Helvetica; font-size:14px; line-height:25px" 让标准浏览器识别display:inline-block;让ie6,7识别display:inline;来覆盖上面的display:inline-block;(我为什么要说覆盖?)。然后通过zoom:1;来触发haslayout让inline元素在ie中表现得和inline-block元素一样。/span
