Is it true that to make a <canvas> element keyboard focusable, you should use tabindex="1" on the <canvas> element?

The correct answer is that it is false to claim that setting tabindex="1" on a <canvas> element is the appropriate way to make it focusable. When creating accessible web content, tabindex values should be used carefully.

If you want to make an element keyboard focusable, you could use tabindex="0", which includes the element in the natural tab order of the page. Using tabindex="1" does allow the element to gain focus, but is considered a practice that can lead to unexpected tab stop ordering, disrupting the natural flow of keyboard navigation. It's important to ensure that focusable elements are in a logical order for the best user experience.

Therefore, while tabindex can be used to manage focus, simply setting it to "1" on the <canvas> element does not follow accessibility best practices and doesn't effectively enhance usability for keyboard users.
