The changes to adapt the color to the theme look good to me. I liked the shadow cat beforehand as well, but this is nicer :D

The last time, you were able to undo the formatting, to keep the original one, can you do the same for this PR?

Some context for the formatting: I don't have anything against this formatting or another one. It's more the fact that everyone might have different settings, and the next PR might then reformat everything again.

For Rust we have rustfmt which enforces the same format everywhere, but we have nothing like that for HTML. We could potentially add one to the CI, but I don't really think it's worth it.

[hamirmahal]

Absolutely! That all makes sense. I just updated the commits.

[xFrednet]

Perfection, like last time. Thank you very much :D
