Hi @Tomomi-K1 ! In review:

• The pull request done with the correct branch
• There is a linked issue: #7764

Issue instruction: Do not use a tab to indent github-handle. YAML doesn't allow tabs; it requires spaces.

• Syntax correct according to YAML standards and specifications of the linked issue

Issue instruction: Using docker, confirm that the appearance of the project webpage is unchanged at all screen sizes.

• No visual changes from PR changes
• Other websites pages tested and working fine

Nice Job! The changes are applicable, don't break anything on desktop or mobile from my testing, and are clean + consistent.

Approved.
