There is hella difference between IE MAC and IE windows.
IE MAC is way more W3C standard compliant( still far behind NS6+) as compare to IE windows.The code written for IE5 is usually the problem.just revisit your code and write proper CSS.This should fix most of the problems...
I've been messing around with IE5/Mac and XHTML. It's frustrating sometimes because there are some annoying bugs, but they've got workarounds. I fought with the same issues you are dealing with in the post below:
Yes you'r right regarding the ID name, but what about the CSS
Do you eant to say that any bug in the HTML coding will affect the functionality of CSS. ( missing cotation here or an attribut there will kill the CSS ?)
Did you try closing the quotes to see if it works?
Hey, whats that <font class="2"> doing in there? Why do you need to use <font> tag? Use <span class="2"> instead.
First step: get rid of all errors
Second step: improve the code by getting rid of deprecated elements where not required (eg. you may leave border for img, etc, but replce font class= with span class=)
Third step: Look for workarounds
I am quite sure its not IE5/Mac thing, its sloppy coding. Improper HTML will affect how the text looks. If your browser doesn't read <font class=" part of <font class="2">, how is it going to render the CSS?
