is there a way to get thread prefixes like xenforo?

I was wondering how to add thread prefixes to threads like xenforo so with like the colored blocks infront of threads like this




but i want to add these kind of prefixes to mybb so the blocks anybody knows how to do that?

I managed to figure it out myself for those who wanna know how i did it. I made a new stylesheet in global.css then use span to show the style
