出于某种原因，我得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，但当我将HTML发布到Blogger.com网站时，它重叠。
我的网站我将其更新为http://clubpenguinspin.com/，正如您所看到的，当您将鼠标悬停在“聊天”时，它有很多选择和奇怪的重叠菜单。下面是它的照片：
看看我的HTML：

<!-- Note how the the closing angle bracket of each </a> tag runs up against the next <a> tag,
to avoid leaving a gap between each menu title and the next one. -->
<!-- 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. -->

这是我的CSS：

border-bottom: #003cff solid 3px;
border-left: #003cff solid 3px;
border-right: #003cff solid 3px;
}
a.navbartitle {
display: block;
float: left;

text-shadow: 1px 1px 3px #000;

text-align: center;
text-decoration:none;
}
a.navbartitle:hover {
background-color: #0241AD;
}
/* menu title widths */
#t1 { width: 104px; }
#t2 { width: 100px; }
#t3 { width: 102px; }
#t4 { width: 102px; }
#t5 { width: 120px; }
#t5 { width: 110px; }
#t6 { width: 120px; }
/* 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). */
.submenu {
position:absolute;
z-index: 2;
top: 23px; /* corresponds to line-height of a.navbartitle above */
padding: 0; margin: 0;
width:166px; /* If adjust this, then adjust width of .submenu below a too */

/* End */
/* position of each sub menu */
/* We just eyeball the position of each submenu here -- can move left or right as needed.
If you adjust menu title text, you might want to adjust these too. */
#products_submenu { left: 0px; visibility: hidden; }
#services_submenu { left: 104px; visibility: hidden; }
#funstuff_submenu { left: 204px; visibility: hidden; }

#contact_submenu { left: 408px; visibility: hidden; }
#contact2_submenu { left: 408px; visibility: hidden; }
#yeaman_submenu { left: 517px; visibility: hidden; }
/* 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. */
.submenu a
{
display: block;

background-color: #005EFF;

请帮帮我！这对我的网站观众和其他人来说非常烦人。

您必须在“即将推出”之后添加结束</a>以及其他链接：

onmouseover="ShowItem('products_submenu');"

幸运的是，问题很简单。在“即将推出”链接的末尾添加</a>：
<a class="navbartitle" id="t6" href="#"
onmouseout="HideItem('yeaman_submenu');"
onmouseover="ShowItem('yeaman_submenu');"
>Coming Soon
我会通过一个细齿梳理，并确保您的HTML设置正确。另外，考虑在可能的情况下从HTML文件中取出JS并制作单独的JS文件？你以后会感谢你自己。
