Missing css, how to update css?

So I’ve built this theme and upgraded it through some updates.
Now I see that some css isn’t there for certain items like the callout. When I change the color, it doesn’t do anything. Also no selector can be found for it in the css.

So I’m thinking my css is outdated and I need to update these things:

  1. Code it myself
  2. Automatically update (possible?)
  3. Having the updated css file and copy pasting it into my theme

I think I’ll have to go with number 3, but even then I’m not sure how to get the latest css files for this.

Can someone point me in the right direction?

P.S. There’s a lot more than just the callout that is missing css, hence the question. Would take a long time for me to code it myself.

What theme is it? Where did you get it?

I created it myself,

I’m not sure I understand your question… I would pick a theme I like that is current for v5 complete already with all of the CSS, and then modify it.

CSS files in folder like “blog”, “general”, “misc”, etc…
AFAIK they do not get updated on a theme you created.
The developer needs to update this aka me.
So I was wondering if there was an easy way to get these.

I guess I’ll just reinstall the dev config so I get the casper theme and get it from there

Btw I’m not modifying an existing theme, my theme is compatible with v5 and took a really long time to create, I’m building upon it not restarting my work lol
