What do you mean by "the banner of the new page header"?

I use this code to generate the Sandbox tab: I originally copied it from SML Wiki, and then I made some changes to the code. Anyways, it still doesn't work correctly in certain situations. I'm sure you can find a better working code on some wiki.
