包含内容CSS的可扩展div

标签： html css html5 css3

我使用margin: 0 auto;将主要内容和导航栏置于屏幕中心，我无法让内容<div>在其中的内容完成时垂直调整大小，我已尝试将{ {1}}对于包含display:inline-block;并且展开但随后它不再居中，div使其居中但不再展开。如果您查看代码，您可能会得到更好的理解，抱歉，如果这没有意义，很难解释。我可以使用任何一个解决方案，非常感谢！ PS。确保运行代码段！

这是代码

答案 1 :(得分：1)

#recent_activity float: right; main_content使vertical-align: top;表现得像#most_frequent。您需要删除浮动广告，并将new ODatabaseDocumentTx("plocal:...").create() 应用于new OrientGraph("plocal:...")

这将解决您的问题。

答案 2 :(得分：0)

您是否尝试为要垂直重新调整大小的div设置宽度？ IE： - 将div设置为500 px宽度 - 任何宽度超过500像素的内容（例如一大段文本）应该只显示在多行上，从而重新调整高度。

你也可以通过将div设置为auto来尝试摆弄div的height属性。
