[转载]关于横向菜单导航。兼容IE6,7,8,Firefox,Chrome。 – nyth – 博客园.
公司人少，所以有时候前台就也做一点。最近一个网站需要做一个横向菜单导航，以前也做过一些小例子想着没啥，网站做完后直接上传，第二天老板可说咋在我这显示不对呀，我过去一看。
突然想起来，IE6没试。我就回来开始调，也没调好，网上也有很多，但是一直也没找个合适的。最后还是google出来了一个外国的网页，一看这个不错。确实很好（它的主要特点是那个JS）。我在网上也搜了不少例子，可是一改就乱，就是这个原因换了好些也没见个合适的。记着，用时查看。。。。。
就这了。有空时，把css给注释下。方便改写。（在调css样式做自己样式的时候，用firbug改着调着很方便）
