我正在使用网格 960 并且无法让 clearfix 工作，但是如果我clear:both在元素上使用，那么我可以获得所需的效果。我更喜欢使用 clearfix，因为我发现它更可靠（通常）。

在下面的代码中，标题部分有一个左侧徽标区域和一个右侧横幅区域，然后在其下方应该是导航栏。

这个导航栏是我遇到困难的元素。如果我添加style="clear:both;"到nav元素，它工作正常。但是，如果我在 header 元素中使用 clearfix，它就不起作用。

这是不起作用的页面（使用 clearfix）

这是有效的页面（使用 clear:both）

Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC.

如果你在你的 NAV 元素之前放置一个空的 DIV 并且上面有一个 clearfix 类，那么这应该可以工作。
