Hi,
There are basic tags that need to be in a html source when you write a webpage. They are <DOCTYPE>, <html></html>, <head></head>, <title></title>, <body></body>, and since you are using CSS you also need a <link rel="stylesheet" type="text/css" href="whateverfile.css" />
For starters you will find at the site I gave you a tutorial on how html works and the basics of what you need. You can look at the source of any website to see the basic parts too.
Here is what you are need for source for a basic website:
HTML Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<link rel="stylesheet" type="text/css" href="whatever_file.css" />
<title>
</title>
</head>
<body>
</body>
</html>
Take the above template and see if you can figure out where things go. I am not going to tell you all of it. But I have faith that you can figure some of it out.
Cheers!
