The DOCTYPE Declaration in your document was not recognized. This probably means that the Formal Public Identifier contains a spelling error, or that the Declaration is not using correct syntax. Validation has been performed using a default "fallback" Document Type Definition that closely resembles HTML 4.01 Transitional, but the document will not be Valid until you have corrected the problem with the DOCTYPE Declaration.
This page is not Valid HTML 4.01 Transitional!
Below are the results of attempting to parse this document with an SGML parser.
1. Line 1, column 0: no document type declaration; implying "<!DOCTYPE HTML SYSTEM>"
<HTML> <head> <title>C.S 1102 project home</title> </head>
The checked page did not contain a document type ("DOCTYPE") declaration. The Validator has tried to validate with the HTML 4.01 Transitional DTD, but this is quite likely to be incorrect and will generate a large number of incorrect error messages. It is highly recommended that you insert the proper DOCTYPE declaration in your document -- instructions for doing this are given above -- and it is necessary to have this declaration before the page can be declared to be valid.
You should place a DOCTYPE declaration as the very first thing in your HTML document. For example, for a typical XHTML 1.0 document:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<title>Title</title>
</head>
<body>
<!-- ... body of document ... -->
</body>
</html>
