licensing webtools in mozilla cvs

Hi,
I'm in the process of opening up the code and web-stuff that I created 
for l10n.
The stuff is in two parts, there is some python code which generates 
json data snippets. I put that code under triple license, I guess that 
fits well.
The other part is a webpage that actually displays this data, as in, 
html/css/js. Most of our websites are under cc by-sa now, is that a good 
license to use or would triple licensing webcontent make sense?

This stuff is hosted on the mozilla cvs repository, for all it matters.

Thanks

Axel
