Help Center 2.0 — scheduled for release May 11, 2021 — does not support CSS customization. Instead, it features built-in customization tools.

Note: users who primarily use the language you’ve removed (and have their browser set to display content in those languages) will still see your FAQs that are set for that particular language.
