填充浮动嵌套div的高度

Question

我正在制作一个基本的评论系统.当评论很短时,这是完美的,但是当用户写了很多时,评论并不像它应该的那样花哨......我试图用高度填充空间:100%; 但它没有像我预期的那样工作.我希望作者信息填写评论的高度.

到目前为止我尝试过的:http://jsfiddle.net/anWVC/3/

HTML:

<div class='comment'>
    <div class="f-left">
        <small style="font-size: .8em;">23:44 - 10/12/2011</small>
        <img src='http://comenzarjuego.com/wp-content/uploads/2010/02/pikchu.jpg' width='96' alt='Avatar' />

CSS:

    text-align:center;
    background: #ccc;
    width: 128px;
    margin-right: 16px;
    height: 100%;
}
.comment{
     background: #aaa;   
}

谢谢!

如果你想让漂浮的左侧面板一直拉伸,你可以用填充和边距做一个很好的技巧:见这里:http://jsfiddle.net/anWVC/19/

诀窍看起来像:

.f-left{
     float: left;
     text-align:center;
     background: #ccc;
    width: 128px;
    margin-right: 16px;
    height: 100%;
    padding-bottom:100%; 
    margin-bottom:-100%;
}

请注意,由于此技巧会将面板拉伸到容器之外,因此您需要将容器设置overflow为hidden:

.comment{
     background: #aaa;   
    overflow:hidden; 
}
