G'day stevieb,

"I'm thinking JS, CSS and other ..."

There's already a page for CSS: "PerlMonks CSS Examples". This appears to have fallen into disuse. It was started in 2002; had quite a few entries over the next two years; nothing for the next six years; and lastly, one (by me) in 2010.

The top of that page shows "#145860=sourcecode"; however, following the link to sourcecode gives me a "Permission Denied" page. From the messages on that page, it looks like you need to be in the SiteDocClan cabal to access it.

There may be similar "sourcecode" pages for JavaScript (and other customising code): I'm only guessing.

So, perhaps there's a way to promote these types of pages. Maybe, given the restricted access, there could also be some sort of mechanism to suggest new content of this type: I'm thinking along the lines of "RFC:" meditations for prospective tutorials.
