added some links and a question
Mentioned my real name, link to JavaScript
I should check for the presence of the CSS cookie.
The code posted previously is incorrect for version 24.3, and it contains a double post of the wrong code.  At least one other user had the same issue with the previous code posted here not working, and the correct solution was posted in a Google Group forum.
A second edit just trying to indent properly so that the code appears correctly.
This is another attempt to differentiate the correct code from the incorrect code -- semi-colons do not permit indentation of code.
Sorry for so many edits.  I'm having difficulty figuring out how to indent properly and distinguish the correct code, while at the same time leaving the code by the previous author.
