OasisRevived

When I install the skin, the contents are fucked up like this:

Any way I can fix this?

I am trying to install OasisRevived on my account. I got the CSS working, but I can't get the corresponding JavaScript to work. I turned on custom JS and entered the code as exactly as it's shown on the article. I even cleared my browser cache and cookies. No matter how I try, the script just won't turn on. What should I do?

How do I add OasisRevived to my computer?

I'm new to CSS in general. However, now with new Fandom design coming, I want to apply the OasisRevived as personal CSS.

I know where the code is and where it's supposed to go. My biggest question is: Can I just copy-paste the entire code, or do I need to do something else?

Can you tell me which code from" MediaWiki:OasisRevived.css "returns the gallery parameters (for example, "bordercolor")? I just don't know myself.
