Board Thread:Support Requests - Designing Your Wiki/@comment-3269579-20130404091346/@comment-4674838-20130404133521

Hey, so just to clarify, generally speaking CSS is used to design how content looks, but it doesn't create new content. CSS does have a background-image property you can use to set the background image of a container. The problem is that that container has to already exist on the page, e.g. in the wiki markup/HTML.

The normal approach I would recommend doing for a case like this is to create a template and add it to all the pages in the category. It sounds to me like you know how to do this, but the sheer volume of pages makes you want to find a more efficient way to do it.

If you're tech savvy, you may wish to look into installing and using your own bot program for automating certain tasks like this. See User blog:Randomtime for a couple good examples introductory posts to 2 of the most common bots used on wikis.

Alternatively, some users here on Community Central will accept bot requests where you explain precisely what you want them to do, and they perform the action with their bot. Feel free to use the forum or ask on chat if you have a bot request, I'm sure someone can help.

Edit: Alternatively, if you're not opposed to doing this manually (pasting a template onto 100 pages by hand isn't really that bad), I can give you tips that will make it go faster. But generally speaking, you'd want to automate these sorts of tedious tasks with a bot.
