css - float 嵌套 div 的填充高度

Question

我正在制作一个基本的评论系统。当评论很短时它是完美的，但是当用户写了很多时，评论就没有它应该的那么花哨了......我试图用height: 100%;来填充空间但是它不像我预期的那样工作。我想让作者信息填写评论的高度。

到目前为止我已经尝试过: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%;

谢谢!

如果您希望 float 的左侧面板一直延伸，您可以使用填充和边距来实现一个不错的技巧:参见此处:http://jsfiddle.net/anWVC/19/

这个技巧看起来像这样:

.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，由于此技巧将面板延伸到容器之外，因此您需要将容器的 overflow 设置为 hidden:

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