When different browsers render the same page differently, the first step to take is ensuring that both your HTML and CSS are valid.

The W3C (World Wide Web Consortium) is the standards body for HTML and CSS, and they've provided free validators online.

HTML Validator [validator.w3.org]
CSS Validator [jigsaw.w3.org]

Once you know your mark-up is valid, then if rendering problems remain, we can help you untangle them. But otherwise, even if you fix the page's appearance in this or that browser, the core problems can always make for trouble in another browser/operating system.
