User blog:WhitePinoy/How to make Templates or edit HTML

So I an admin for the wikiLollipop Chainsaw. I am currently going under some refurnishments, and I wanted to know how to edit HTML's. Is there anywhere I can go to that will educate me on editing templates.

I was considering making new things for the wiki: There is probably more I would be interested in learning, but I can't really think of anymore.
 * Making Fancier Templates
 * A "Featured Character" Template
 * Modifing the shape of a slideshow panel
