To display the formatted code in a html page, the web page must refer to a stylesheet that defines the formatting for the different CSS classes generated by code formatter: .codeformat, pre, .rem, .kwrd, .str, .op, .preproc, .alt, .lnum.

Note that if you have multi-line comments in your source code (like /* ... */), the "line numbers" or "alternate line background" options will generate code that is not strictly HTML 4.01 compliant. The code will still look good with most modern browsers
