CSS Help

I run a site, where the CSS looks fine on most clients except Macintosh IE 5.2. I read somewhere that my CSS is wrong, that Mac IE uses the most correct CSS code. I had one of those online tests test my CSS and it said it was fine. All I want to do is fix my CSS so it works good in MAC IE. The problems are that when I hover over a menu item, the text in the main body (separate table cell) moves all over the place. If you are good at CSS and would like to check out the page to help me, let me know.

i'll take a look go ahead and post the link or the actual CSS code you're using..

This was my post.. but somehow I wasn't online.. thanks Notepad, I hope you find some error in my coding.

your code looks pretty basic and straight forward to me.. i see three possible things that might be causing it to shift onMouseOver and have labeled them below. try removing the marked items to see which one is causing it

.PhorumBodyArea
{
font-family: Verdana, Arial, Clean, Helvetica, sans-serif;
font-size: 12px;
width: 500px; <<---REMOVE THIS
}

A.menu:hover
{
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size: 12px;
font-weight: normal;
text-decoration: underline;
color:#FFFFFF;
margin: 0px; <<---REMOVE THIS
border: none; <<---REMOVE THIS
}

I'm at home on my win98 machine, but when I get back to work tomorrow morning, I'll test it out. Thanks for your help, it's very important to me that the site loads and displays well on most if not all browsers.

Thanks Notepad! As you can probably see I am not the CSS expert, and I actually copied most of that from another page. I fixed the A:hover but not the Phorum tags, because I never have a problem with those. Thank you very much, it seems to have fixed the problem! Awesome! Among the suggestions I got : tell the users to download a new browser, yeah right! Just wanted to fix it! If there's anything I can do for you Notepad, please don't hesitate to let me know.
