None of my CSS styling is showing when I preview.

Here is my html file and CSS file. I can't figure out why my CSS isn't applying.

Hi Jozef,

A couple things.

Are all your style sheet links in inside <head></head>? Do you have a folder named "css" in your file directory? Are html tags included in your html file?
