IE7 Dropdown Menu Issue_问答_开发者_运维开发者技术经验分享

I've got a dropdown menu setup. Works fine in Firefox / IE8 etc. But not in IE7, Ideally I would like to get this to work. The menu dissapears when I hover over it in IE7. I've tried playing about with the height but had no joy.

My code is as follows...

CSS..

#topNav ul {
    list-style:none outside none;
    margin:0;
    padding:0;
}
#topNav ul, topnav ul ul {
    display:block;
    margin:0;
    padding:0;
}
#topNav ul li {
    display:inline;
    float:left;
    padding:35px 24px;
    list-style:none outside none;
    position:relative;
}
#topNav ul li ul {
    color:#000000;
    display:block;
    position:absolute;
    top: 68px;
    visibility:hidden;
    width:180px;
    z-index:1000;
    height: 200px;
}
#topNav ul .home a, #topNav ul .coffeetable a, #topNav .coffeetable a, #topNav .audio a, #topNav .graphic a {
    color:#ff9966;
}

#topNav ul .photography a, #topNav ul .video  a, #topNav ul .web a, #topNav ul .contact a {
    color: #fff;
}

#topNav ul li ul li {
    color:#FF7E00;
    display:block;
    margin:0 0 5px;
    padding:15px;
    width: 240px;
}

#topNav ul li ul li a {
    color:#000000;
    display:block;
    margin:0;
    padding:5px;
}

#topNav ul li.submenu:hover ul {
    left:0;
    visibility:visible;
}

#topNav ul li.submenu:hover ul li {
    background-color: #000;
    margin:0;
    padding: 10px 10px;
}

How can I fix this so that the hover doesnt break? Thanks in advance guys.

If that's the case...All I can suggest is to double check to make sure your browser & document modes are definitely in IE7 mode, read up about IE7 Z-index approaches. trial and error css position types, I believe there's some glitches with IE7 to do with css display types (hidden).

clean up your CSS, I know everyone will be like "what" but sometimes you find nice fixes when you remove errors as some browsers are more sensitive & strict to things like spaces around selectors, commas etc.

If all of that doesn't work and you scale the web looking for a solution, and you find nothing. Just make an IE7 redirect (you can do this without JS), IE7 is not worth the stress unless your client & clients clients are frequent users of IE7 such as tight ass corporations who don't want to upgrade.

Hope that helps

(sorry I only looked at your code for 2 seconds)
