You can now see where you are when you tab through a form

If you use a keyboard rather than a mouse to move through the site, you need to be able to see which control you are on. On our checkboxes and radio buttons, you could not.

The reason was a detail of how they are built. The real checkbox is hidden and a styled box is drawn in its place, and the only thing that changed when you tabbed to one was that box going from white to a very slightly greyer white — the same thing it already did when you simply hovered over it. In practice that meant tabbing through the job filters, your notification settings, the get-started questions or any of our submission forms with no reliable way to tell where you were.

Now every one of them draws a clear blue ring when the keyboard reaches it, matching the other controls on the site. It appears for keyboard use only, so clicking with a mouse does not leave a ring behind.

This is part of our ongoing work against WCAG 2.2 AA, and it is now checked automatically: a browser walks twelve of our busiest pages, presses Tab through more than a thousand stops, and fails the build if focus ever lands somewhere you could not see.
