CSS左右分割页脚

时间：2012-07-07 23:00:46

标签： css

我知道如何通常做一个简单的浮动左侧和右侧浮动来制作我可以轻松获取信息的区域。但基本上我使用HTML5 Boilerplate，我相信当我试图分割我的页脚而不是什么时候，由于之前应用的样式，它不起作用。现在我不是CSS专家所以我可以做一些小帮助，告诉我如何将这个基本功能放到我的页脚中。它的分裂2cols，左对齐和右对齐。

下面的HTML和CSS。先谢谢你们！

2 个答案:

答案 0 :(得分：3)

brains911所说的内容会有所帮助，但我也建议在<footer class="wrapper">中添加clearfix。

所以你的代码看起来像这样：

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

如果这没有意义，请告诉我。

答案 1 :(得分：1)

h3.left { float: left; }和 h3.right { float: right;}看起来应该在做这项工作。您可以尝试为每个人添加width:50%。

您是否可以使用firebug来关闭影响h3元素的其他样式，看看是否确实存在问题？
