Forum:MediaWiki and colons

I've been trying to add backgrounds to certain pages of my wiki, and I have gotten help with it and tried to learn from it. My next attempt was to add background to pages that have an additional text after a colon. Only the MediaWiki takes the colon as a code and turns it green, so it doesn't reach the additional text. -- Bunai82 (talk) 15:28, October 25, 2011 (UTC)

 * That's because you can't have a colon in a class name or id. Instead, MediaWiki will encode it as an underscore. Keep in mind that the space is also an underscore, so the page  would be encoded as , not.
