PC/Mac compatability issues ><

Eugh, frustrating.
Mac:

1. I'm not worried about fonts and stuff just yet.
2. I know the top of the header is cut off in the PC pic - that was the screenshot, not an error.

What I need to know is:
Why is it that on my Mac (in FireFox and Safari), there is a nice line between the navigation and the content but on the PC (in both FireFox and IE) there isn't. Also, why is it that on my Mac (FireFox and Safari), the "useful links" box appears where it should, on the right, but on a PC (only in IE) it's underneath the services box. It can't (or shouldn't) be a resolution issue because when I make my Mac browser really small, it just scrolls across, none of the layout changes.

The only reason I can come up with is Mac > PC ^_^ but that doesn't solve my problem... can someone help me?

The index file is here:

The CSS file is here:

Thanks! =)

EDIT: And wow... just tested it in Opera and all I can say is... o_0

Those images won't work, they don't allow hotlinking.

Are the differences you're talking about differences between browsers rather than Mac and PC? If so you might want to edit the title. Browser differences are nothing to do with the OS, and I've never got a web page to look identical on every browser using CSS - it can't be done, more often than not because of bugs in Internet Explorer.

Ah thanks... that's stupid, they used to. Oh well. Fixed now.


Both screenshots were taken in FireFox.

EDIT: Holdon... let me edit the first post again. Ignore the thing I said above.

Then the problem is FireFox - the OS doesn't render web pages, Gecko (FF's rendering engine) does.

In that case... I would change the title if I could.

so... you're saying the same browser (same version and all) is rendering the website differently depending on the OS? :S that seems VERY unlikley
