Is there an add-on that allows users to apply their own css formatting to their posts, using pre-made custom tags (like bbcode) that the users define?
If there isnt an add-on to do what I mentioned first, then would it be possible to make one? I am interested in making it, because I think it would be invaluable.
I and I dont really care about the 'feature' being exploited by users adding their own css to seriously screw with the page, because its only for devolpment and testing etc
Is it necessary for all users to have the ability to add tags? It's pretty easy for the admin to manually add custom tags into one of the existing parsers. For example, I've added custom tags into Forced BBCode by simply following the format used it's parser file (BBCodeParser.php).
Otherwise, it's certainly possible to write such an extension.
