This has to do with how each browser implements the different web standards.  There is a tool that I would suggest you might look into call Expression Web SuperPreview.  This is a tool we've built to help web designers/developers see how their sites are going to look in different browsers while designing/developing.  You can get the tool and read more about it at:
