Explainer
None.
Spec
The HTML spec lists scrollable regions as [potential] focusable areas but doesn't enforce a default tabIndex value (confirmed at GitHub).
Summary
Make scroll containers focusable using sequential focus navigation by changing their default tabIndex value from -1 to 0.
Motivation
Today,
the tab key doesn't focus scrollers unless they explicitly got tabIndex >= 0. By giving scrollers a default tabIndex of 0, users who can't (or doesn't want to) use a mouse will be able to focus and read clipped content by using a keyboard's tab and arrow keys.
Link to “Intent to Implement” blink-dev discussion
None. Already implemented. The code change is small.
Link to Origin Trial feedback summary
None.Is this feature supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?
Yes.
Demo link
See the CL's test.
Interoperability
Edge: No signals
Firefox: Shipped (a long time ago)
Safari: No signals
Web developers: Positive signals
Compatibility
Affects the tab order of documents that have overflow: scroll|auto-elements that contain clipped content.
Ergonomics
Web pages developed with [keyboard] accessibility in mind already work around this difference to Firefox by manually overriding Chrome's default (tabIndex=-1) with tabIndex=0 on scrollers.
Activation
Web pages not developed with [keyboard] accessibility in mind will immediately become more accessible to users who cannot, or doesn't want to, use a mouse.
Is this feature fully tested by web-platform-tests?
The CL has wtp-like tests that we can upstream once testharness.js gets a browser-independent way to trigger sequential navigation.
