Desperately need help for webpage to view in all browsers

[clandest]

Ok, So I just coded a webpage and I am on a mac, so I use safari and it looks good. Just how I want it to look. But when I viewed in IE and FF it looked like crap..

Can anyone help me please get my webpage to look like it should in those browsers?
