如何解决IE6/IE7不识别display:inline-block属性
(编辑：jimmy 日期: 2024/11/26 浏览：3 次 )
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://www.w3.org/1999/xhtml”> <head> <meta http-equiv=”Content-Type” content=”text/html; charset=utf-8″ />
<title>display-block</title>
<style>
span {
width:200px;
height:50px;
margin:10px;
padding:20px;
background:#ccc;
zoom:1;
</style>
</head>
<body>
<span><span 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>
