Shift+Tab

Navigate the web the way millions of people do every day. Then fix it.

Friday Community Night is coming, and the Commons website isn't ready. Seven community members who use a keyboard, a screen reader, switch access or a head pointer have filed issues: they can't sign up, register, RSVP or donate.

You're a first-time open source contributor. For each issue:

1. Reproduce it with the same input the reporter uses: keyboard only, a screen reader view, or mouse and touch.
2. Fix it by choosing a suggested code change. Careful: some wrong fixes pass the automated checks and still don't help real people.
3. Merge it when the accessibility checks pass, and hear back from the person who reported it.

You'll practice 13 WCAG 2.2 success criteria, including focus visible, accessible names, keyboard traps, form errors, target size and time limits.

Accessible by design. Playable with only a keyboard, with a screen reader, or on touch. Respects reduced motion, with no flashing and no timed failure. Every update is tested automatically with axe-core and a full keyboard-only playthrough.

This game doesn't simulate disability. It teaches how assistive technology works and what developers need to build.

Made for #GitHubGameOff 2026, theme SHIFT: Shift+Tab is the key that moves focus backward, and the game is about shifting perspective.
