使用上面和下面未知高度div的CSS将div设置为剩余高度

Question

是否有可能使包装器填充窗口高度(没有滚动)和中心div可滚动而不会弄乱像素和JavaScript？

<div id="wrapper">
  <h1>Header</h1>
  <div id="center">
    <div style="height:1000px">high content</div>
  </div>
  <div id="footer">Footer</div>
</div>

基本上我希望标题在顶部可见,页脚始终在底部可见,并且在中心有一个可滚动的内容,占据了重新生成的高度.
页眉,页脚和中心div的高度都是未知的(没有设置px或%,即可变字体大小或填充).纯CSS可以吗？

2014更新:解决此布局问题的现代方法是使用flexboxCSS模型.它受到所有主流浏览器和IE11 +的支持.

2012:单独使用CSS的正确方法是使用display: table和display: table-row.从IE8开始,所有主流浏览器都支持这些浏览器.这不是使用表格显示.你将使用div:

html, body {
    height: 100%;
    margin: 0;
}
.wrapper {
    display: table;
    height: 100%;
    width: 100%;
    background: yellow;  /* just to make sure nothing bleeds */
}
.header {
    display: table-row;
    background: gray;
}
.content {
    display: table-row;  /* height is dynamic, and will expand... */
    height: 100%;        /* ...as content is added (won't scroll) */
    background: turquoise;
}
.footer {
    display: table-row;
    background: lightgray;
}

<div class="wrapper">
    <div class="header">
        <h1>Header</h1>
        <p>Header of variable height</p>
    </div>
    <div class="content">
        <h2>Content that expands in height dynamically to adjust for new content</h2>
        Content height will initially be the remaining
        height in its container (<code>.wrapper</code>).
        <!-- p style="font-size: 4000%">Tall content</p -->
    </div>
    <div class="footer">
        <h3>Sticky footer</h3>
        <p>Footer of variable height</p>
    </div>
</div>

而已.div正如你所期望的那样包裹起来.
