This doesn't seem to be loading properly on e.g. https://deploy-preview-6485--knative.netlify.app/docs/ if you search for "auto".

(Part of it may be needing to remove the overrides/assets path.)

I'm also wondering if this should simply go into extra.css, as home.css is specific styling for the homepage, which has custom-written HTML.

[codeEvolveZenith345]

ok I will look into it and make an implementation as instructed !
