The HTML returned by pretty_file doesn't contain any CSS. To properly apply the style to a page, ask to generate the style sheet by activating the line 74 of the code and save it in a file in the folder css/geshi.

EXAMPLE

To add the CSS for the Python language, call pretty_file with as first argument a file hello.py and 'python' as second argument. Copy from the output, before the code in HTML, the CSS for the class .python, and save all the lines in the file css/geshi/python.css at the root of website.
