Home page animation violates WCAG 2.0 A 2.2.2 Pause, stop, hide

[CharlesBelov]

The GitHub home page animation for not-logged-in users lasts longer than 5 seconds. Under WCAG 2.0 A 2.2.2 Pause, stop, hide, a visible pause button is required.

@CharlesBelov i assume this is the same/similar issue documented in #17230. Is that correct?

[CharlesBelov]

It's related. #17230 (respecting prefers-reduced-motion to automatically not serve any animation) is polite behavior which is not mandated by WCAG. #17228 (allow pausing any animation longer than 5 seconds) is mandated by WCAG 2.0 at the A level. They are complementary rather than duplicate or mutually exclusive.

I suppose I could have filed them as a single issue. I tend to treat technically different issues discrete from one another. That said, one could choose to consider them together.

Hello @CharlesBelov - thank you for being a part of our community and taking the time to submit feedback. I'm happy to report that a pause/play button has been added to the globe animation for the logged-out GitHub homepage experience.

I am including two screenshots, the first image shows the default state with a red arrow pointing to the "pause" button. The second image shows the toggled state with a red arrow pointing to the "play" button. You will see this button when your OS prefers-reduced-motion option is not set to true/toggled on.

Note: there is work still being done on the other issue you created called GitHub home page does not respect prefers-reduced-motion. We hope to have an update for that issue soon.
