复杂的CSS定位

标签： css html css-position

我想用CSS实现这个定位：

enter image description here

但经过几天尝试后我获得的最好成绩是：

enter image description here

考虑到这一点，你能帮我实现这个定位吗？

  • “try”图片中的红色注释（参见下面的JSFiddle）表明了一些主要的约束
  • 定位应该适用于IE8 +，FF10 +，Chrome，Opera，Safari（使用CSSPie和selectivizr兼容IE8）

以下是 JSFiddle 和代码：

HTML 

<body>body (all divs may have some padding, some margin and some border. All divs adjust their height to their content.)
<div id="globalcontainer"><span class="important">#globalcontainer (fixed width, not really centered into body : see center)</span>
  <div id="header">#header (100%)</div>
<div id="middle">#middle (100%)
  <div id="left">
    <span class="important">#left (on the left of content, with a fixed min-width.<br>
     <br>
 Width adjusted to content if content &gt; min-width. <br>
<br>
      If left+right+center min-width &gt; global container width, then still adjusts its size to its content and goes outside globalcontainer limits.<br>
<br>
      Inner divs have variable (and unknown) width, sticked to the right)</span>

      <br>
      Stays centered on the screen whatever the left or right size are<br>
      &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; --&gt; if left or right divs are not present in the HTML (or present with display:none), center div stays on the center of the screen)</span>

使用边框框模型是正确的方法。

这是我经常使用的结构：demo

它使用一些包含position: relative;和自定义填充的包装div，其中包含height: 100%;和overflow :auto;的绝对定位元素。

需要调整，但你会得到要点。

对于如此复杂的布局，以及border-box，您还需要仔细调整所需外观的尺寸。
