This seems to be a change not related to :hover

changes cannot be made directly to vocabulary.css in downstream projects, and should instead be made as override styles within the local style.css file.

Hi! and thanks for this contribution! The color choices here do not satisfy appropriate Usability or Accessibility standards.

Changes to the buttons in the content area make sense here in this project, but adding hover behavior to the header would be better within the main Vocabulary repository so that it could affect downstream projects more consistently.

Hi, and thank you for doing this work. After further review the Issue in question here as moved to 🚧 status: blocked Blocked & therefore, not ready for work so I'm closing this PR for now.
