我正在使用网格960，无法使clearfix正常工作，但是，如果在元素上使用clear:both，则可以得到所需的效果。我宁愿使用clearfix，因为我发现它更可靠（通常）。
在下面的代码中，标题部分具有左侧徽标区域和右侧横幅区域，然后在其下方是导航栏。
这个导航栏是我遇到的困难。如果将style="clear:both;"添加到nav元素，则可以正常工作。但是，如果我在header元素中使用clearfix，则它不起作用。

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.
