If you are just using this to learn to develop WSGI applications, I would  
recommend implementing a method to distinguish requests for static files,  
and handle them separately. A very naive implementation handling .css  
files might look like:

	from wsgiref import util
	import os

	def do_get(environ, start_response):
		REQUEST_URI = util.request_uri(environ)
		if (REQUEST_URI.endswith('.css')):
			return do_css(REQUEST_URI, start_response)
		# your regular code here

	def do_css(request_uri, start_response):
		full_path = os.path.abspath(os.path.join(MY_HTTP_DIRECTORY, request_uri))
		if os.path.exists(full_path):
			file_obj = open(full_path, 'r')
			response_lines = file_obj.readlines()
			start_response('200 OK', [('Content-Type', 'text/css')])
			return response_lines
			start_response('404 Not Found', [])
			return []

However, this method is fragile and very inefficient. If you want to  
eventually deploy this application somewhere, I would suggest starting  
with a different method.

Hope that helps,
