基于以下答案的大规模编辑
原帖在这里http://webmasters.stackexchange.com在miration之前。
我终于在所有浏览器（所有主要浏览器；Chrome、Opera、Safari、Firefox）上进行了页面布局，除了 IE 9 和可能的旧版本。目前，链接在第二个链接（具有下拉菜单）之后停止显示在“导航”栏中。链接对于下拉菜单都是水平安全的，直到第三个链接出现，它们都显示在“导航”栏下方并作为垂直列表显示。我确信这个问题需要一个单独的 IE 样式表，但问题是主样式表还是菜单样式表，目的是什么？
这是布局的图片：

/* ~~ These are the columns for the layout. ~~
1) Padding is only placed on the top and/or bottom of the block elements. The elements within these blocks have padding on their sides. This saves you from any "box model math". Keep in mind, if you add any side padding or border to the block itself, it will be added to the width you define to create the *total* width. You may also choose to remove the padding on the element in the block element and place a second block element within it with no width and the padding necessary for your design.
2) No margin has been given to the columns since they are all floated. If you must add margin, avoid placing it on the side you're floating toward (for example: a right margin on a block set to float right). Many times, padding can be used instead. For blocks where this rule must be broken, you should add a "display:inline" declaration to the block element's rule to tame a bug where some versions of Internet Explorer double the margin.
3) Since classes can be used multiple times in a document (and an element can also have multiple classes applied), the columns have been assigned class names instead of IDs. For example, two sidebar blocks could be stacked if necessary. These can very easily be changed to IDs if that's your preference, as long as you'll only be using them once per document.
4) If you prefer your nav on the left instead of the right, simply float these columns the opposite direction (all left instead of all right) and they'll render in reverse order. There's no need to move the blocks around in the HTML source.
