<h1>固定中栏宽度, 左右两栏宽度相等和自适应</h1>

<p><strong>表现:</strong>中间一栏居中与固定宽度，左右两栏宽度相等同时自适应宽度。</p>

<div id="middle">
<div id="innerMiddle" class="inner">
<p><strong>原理:</strong>利用margin的负值错别固定的宽度，因为要分两边，所以只要错开一中间的固定宽度就行</p>
</div>

<div id="right">
<div id="innerRight" class="inner">
<p><strong>问题:</strong>IE对宽度乘百分比的计算不大好，有必要牺牲一两px的显示，IE6也没最小宽度。</p>
