How does the "Weegeepedia" have a lot of their "Mediawiki" customized?

Like above

And no, I don't want to make the other Language versions of my wiki

(Continued from title) on your wiki like General or Off-topic?

Achievements

This isn't the first time I'm asking for help with Badges, 4th time! And I am kind of getting tired, I sent 3 requests to the admins and they're still not added! Are they that busy? I want a solution for this problem, quick, or I will have to live without Badges

Languages

How do you switch between Languages on the wikis? Do you hire a translator, or another thing is required? Please let me know down the comments below

I recently noticed this in the Theme Designer, I added an image, but honestly I have no idea what that means.

Im currently using this feature to add multiple images to the infobox

But the problem is, that the text colors blend right with the color of the infobox (on the left of "Animated" theres text saying "Static). How can i change that?

Plus its currently not centered, how could i fix that too?

Heres the link to the template and page

I've created a recent edits activity box here https://doodle-world.fandom.com/wiki/Template:Home-Activity-Feed and I was wondering if I could make something similar for images and/or discussion feeds? Any help would be much appreciated

Hello, so I've been working on my wiki and I made a template about some metro maps...

Edit: So there are two boxes here, one orange one blue. What can I do if I need to merge them together into one big box?

How can I make an announcement on a post?

How exactly DO I edit CSS? my anxiety has been attacking me with this for a little bit now, I'm trying to get this on the Splatoon Wiki, I've read the Custom Wiki about it but I can't grasp onto it, where do I even put the code?

The Amphibia wiki has this really cool glowy green design. I've been trying to figure out how to get that effect for the wiki I'm working on. As well as other equally cool styles.

Basically, I tried doing those tabs images to a infobox just like this picture

I’m using the portable infobox, is it possible to do it?

Its at the coner and it is a box thing, i cant find an example, but it is a little box at the corner of the screen when you go to a wiki

This wiki called "floppapedia" has stat display more than that of my own wiki, how do i show how much activity has been going?

Yes, I wanna make the custom table like this wiki

Because yeah

What is the thing above called? And how do I add one to another wiki? I am trying to design my wiki and I can't figure out what it is. I don't know what it is called or I would have tried to find it in Help.
