Hello, hello,

 

Little bit stuck with some drop down menus:

 

In Chrome - my main browser - they behave exactly as expected.  The menus are the same size as the Subject links and the X at the end of each link under subject one (which I added for no other reason than to see if I could) Appears neatly.

 

In Mozilla Firefox - The dropdown menus are the right size, the same as their parent Subjects but in the first menu the X appears to be off the bottom of each link area and the bottom of the menu has a think Cyan strip.

 

In IE - It's a complete mess, the menus are larger than their parent and the first menu, although it behaves correctly has a thin Cyan strip down the side and a thick one at the bottom. (Comparison with the other browsers leads me to believe that it's not actually the menus that are larger but rather the Subject headers that are smaller than the 140px they are supposed to be set to).

 

I'm posting this here because I figured it's a CSS problem to do with different browser behaviours, I just don't know how to correct it or what I should be looking for.

 

Here's a link to the page so you can see it: http://90.221.181.204/ (I've temporarily enabled forwarding of port 80 through my firewall to be sent to my Apache server)

 

Here's the actual page code:

It's just a small experiment page so I haven't bothered separating the JS and the CSS into different files.

<html>
<head>
<style type="text/css">
<!--
#dropDownMenu {
margin: 0;
padding: 0;
/*z-index: 30*/
}
#dropDownMenu li {
margin: 0;
padding: 0;
list-style: none;
float: left;
font-family:Arial, Helvetica, sans-serif;
font-weight:bold;
font-size:11px;
}
#dropDownMenu li a {
display: block;
margin: 0 1px 0 0;
padding: 4px 10px;
width: 120px;
background-color:#6666CC;
color: #FFFFFF;
text-align: center;
text-decoration: none;
}
#dropDownMenu li a:hover {
background-color:#6699FF
}
#dropDownMenu div {
    width:138px;
position:absolute;
visibility: hidden;
margin: 0;
padding: 0;
background-color:#00FFCC;
border: 1px solid #6666CC
}
#dropDownMenu div span {
    visibility:hidden;
float:right;
}
#dropDownMenu div a {
position: relative;
display: block;
margin: 0;
padding: 5px 10px;
width: auto;
white-space: nowrap;
text-align: left;
text-decoration: none;

I knew I hadn't finished that post -

 

I realise that the cyan areas are being caused by the <span> tag being shown differently in different browsers.  Could someone explain the what and why of that?

 

Also could someone explain the why of the Subject headers being smaller in IE than in Firefox and Chrome?

Well, I'm going to mark this one solved.

 

Re-inventing the wheel using the suckerfish menus as a guide has taught me a bit and the problems I was having with the previous version have vanished.

 

My server is still running on the same IP for the moment so if people want to have a look at my current version then they're welcome.

 

I'm marking this as solved now.
