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: http://expression.microsoft.com/en-us/dd565874.aspx
