HTML 2 - Frequently Made Mistakes (FMM)
In the last class a student recommended that I develop a page I could direct students to when they can't solve a problem with their work. Students would have a resource to consult on their own - to see if their problem was a FMM, and I could save myself a lot of work answering the same question again and again.
Here are a couple of FMMs from the HTML 1 class, and I will add more as we learn new techniques in this class.
- Question: When I click on the XHTML validation button, why am I getting the message "Sorry! This document can not be checked." in the orange bar and "No Referer header found!" just below it?
Answer: You are trying to validate a file that llives on your computer. The only files that validate immediately are the files that live on the student server. You can continue the validation process, however, by clicking on the link that says "Validator Home Page". Then you have a choice to Validate by File Upload or Validate by Direct Input (copy and paste.)

Question: When I click on the CSS validation button, why am I getting the message "Some Headers, mandatory for this resource, are missing. Referer"?
Answer: Same as Question #1. With the CSS validator, however, there is no link that allows you to push through to validate anyway. You can, however, open up the CSS validator separately, http://jigsaw.w3.org/css-validator/, and validate by File Upload or Direct Input.

Question: Why can't I delete that folder on the student server?
Answer: A folder cannot be deleted on the student server unless it is empty. Some of you, Mac users in particular, will have hidden files in your folders that must be displayed and deleted. The Fugu command for displaying hidden files is found in the SFTP menu, and the SSH command is found in the View menu.
Note: Never, ever mess with the public_html folder - rename it, delete it, whatever. It's not a normal folder and you will have to have system administrator assistance to restore your workspace.

Question: Why can't I see my assignment from the Class Gallery?
Answer: There are two primary reasons for this problem:
- did you name the file EXACTLY according to the assignment requirements?
- did you place your file in the proper folder?
