无意中看到一则关于div底部对齐的文章，延伸一下，修改成自适应高度，还没有真实应用，未知会否有其他问题

<style type="text/css">
        .aa{height:100%;width:100%;background:#ff0099;position:relative;font:12/24}
        .aa div{width:778px;}
        .bb{width:200px;background:ccc;height:100%;position: absolute;bottom:0;left:0px;}
        .cc{background:fdfdfd;height:100%;position: absolute;bottom:0;left:200px;}
</style>
<div class="aa">
        <div class="bb"><a href="####" target="_blank">left</a></div>
        <div class="cc">right</div>
</div>

height:100%这样的写法好像是不管用的哦……
