Help with Frontpage 2003

I'm trying to design my first site using frontpage. Everything
is going ok except for the fact that Firefox won't display the pages correctly when IE does. Any ideas?

 

IE and Firefox render differently. There are quite a few things that you have to "hack" to get to work right in both. Often times, people implement two different styles, one for IE and one for Mozilla. So that's what's causing it.

 

So how do I go about making both browsers work?

 

Depending on the formatting method you are using you will probably need to start by understanding the differences between how IE and Mozilla render elements when formatted with CSS. You will probably quickly find that Front page is not that ideal when building web pages.
