I'm in the process of building a webpage and I have opera, Firefox and IE7 on my PC (and use Windows XP SP2). I was wondering if I should be checking the design with any other browsers and/or operating systems?

I'd still check IE6 since most people still have it for now and many will probably be using it for quite some time too.

You might also want to look at Safari. If you don't have a Mac you can check the site by going to:

http://www.browsrcamp.com/

I think that should cover you pretty good. There are plenty more browsers you can check, but you'll probably be covered for over 99% with those.

I mainly use safari more than any other browser. I use it because it loads sites faster than firefox. Safari is also really good with code. I have found a couple of issues with Javascript though. In which they worked for everyother browswer except Safari. But that's it. I would still try to have your site checked with Sarfari.

vangogh had the right idea, but there is a better site out there.

www.browsercam.com . You get a 24-hour free trial of it, which should be all you need to get the major bugs out if nothing else.

The one browser I would add to your list off the top is IE6. Even though IE7 is newer, it's not anywhere near as common...yet. That, and it only works with XP.

Nice link Adam. I have a few similar ones, but that's one I missed.
