I've been reading and reading and readin and it's INFURIATING how little I can find on what I'm supposed to do to format infoboxes. I have fairly limited knowledge of coding, but once I get a basic idea of something specific, I can make a start towards something using that basic idea, and then organize it little by little as I learn more. Problem is, I can't figure out where to go from here. Nothing I look up has produced any results that I can apply.

I ask, "How do I give my infoboxes rounded edges?" and every result is either an extremely vacant post where the OP and commenters exchange technobabble that gets me nowhere, or post a very straight-forward "Put this code right here in your source editor." which would be fantastic if I had more info to go off of than just "in your source editor".

I apologise for ranting but I've been trying to do this for two days and have had zero luck.

What I am trying to accomplish is making character infoboxes for an RPG. I want the title at the top to be a pill shape, with all four corners rounded, and everything beneath the title to be contained within one rounded rectangle. Additionally, I'd like to be able to colourize the template on a per-character basis.

Now you can just tell me to do something with CSS, but the thing is, I haven't made one yet and I have no clue how to go about making one. I know what CSSs do, but the formatting needs to be explained to me in detail for me to be able to even begin knowing what to do with one. So please, if you can possibly help me out, give me a shout. I'm lost and as the game's de facto wiki worker, it's swiftly starting to become exhausting.
