A friend of mine (who shall remain nameless) IMed me late last night to say she was having a problem with the web page she was designing not displaying any of the CSS styling. Also, none of the links on the navigation were working right. She asked If I could take a look at it since she had been trying to figure out the problem for an hour and a half with no luck. She gave me the URL and off I went to take a look at the source code.
It didn't take long to spot the problem: She had uploaded all the files to the server, but in her XHTML code, all of the links (including the link to the CSS file) were still pointing to files stored locally on her computer.
