I am very new to SharePoint and .NET in general. I know the basics, like creating masterpages and registering controls and some things like that, but beyond that...not so much.

I have a client who needs some SharePoint templates. I told my clients development team that I would be creating these templates to work in IE6, 7 FireFox and all Safari and the site would be table-less. They told me that I can't use DIV tags because SharePoint + FireFox and DIV tags don't work well together. Is that true?? Are DIV tags an issue when creating SharePoint templates?

Thanks in advance!
