出于某种原因，我遇到了一个奇怪的重叠下拉菜单故障。当我用 Firefox 打开它时它工作正常，但是当我将 HTML 发布到 Blogger.com 网站时，它会重叠。
我正在将其更新到的网站是http://clubpenguinspin.com/，如您所见，当您将鼠标悬停在“聊天”上时，它有很多选择和奇怪的重叠菜单。这是它的图片：
看看我的 HTML：

<!-- REPLACE each "placeholder.html" URL below with the specific page you want the user
to go to when the given menu title is clicked. For example, the first link below
is for the "Home" menu title, so you'd probably replace the first URL with index.html. -->

/* We just specify a fixed width for each menu title. Then, down below we specify
a fixed left position for the corresponding submenus (e.g. #products_submenu, etc.)
Using these fixed values isn't as elegant as just letting the text of each
menu title determine the width of the menu titles and position of the submenus,
but we found this hardwired approach resulted in fewer cross-browser/cross-OS
formatting glitches -- and it's pretty easy to adjust these title widths and the
corresponding submenu 'left' positions below, just by eyeballing them whenever
we need to change the navbar menu titles (which isn't often). */

padding: 0; margin: 0;

If you adjust menu title text, you might want to adjust these too. */

/* Note, each submenu is hidden when the page loads - then made visible when
the mouse goes over the menu title. Using the 'visibility' property instead
of using the 'display' property avoided a bug in some versions of Safari.
(The bug is pretty where esoteric: The browser ignored the 'hover' property
on 'li' objects inside an object whose display property was set to 'none'
when the page loaded...) Using the 'visibility' property instead of 'display'
would normaly take up extra room on the page, but that's avoided here by putting
the submenu on a second layer: see 'position: absolute' and 'z-index: 2'
in .submenu definition, higher up this page. */

请帮我！这对我的网站浏览者和其他人来说非常烦人。
