我知道通常如何做一个简单的向左浮动和向右浮动页脚以使我可以轻松获得信息的区域。但基本上我使用了 HTML5 样板，我相信当我尝试拆分页脚时，由于应用了以前的样式，它不起作用。现在我不是 CSS 专家，所以我可以做一些帮助，告诉我如何将这个基本功能放入我的页脚。其拆分 2cols，左对齐和右对齐。

下面的 HTML 和 CSS。提前谢谢各位！

Brains911 所说的会有所帮助，但我也建议在其中包含一个clearfix<footer class="wrapper">。

所以你的代码看起来像这样：

<footer class="wrapper clearfix">
...
</footer>

让我知道这是否没有意义。

h3.left { float: left; } h3.right { float: right;}看起来他们应该做这份工作。您可以尝试添加width:50%到它们中的每一个。

您可以使用 firebug 来关闭影响 h3 元素的其他样式，看看这是否确实是问题所在？
