Your daily frequent11y newsletter, brought to you by @ChrisBAshton:

What is ARIA even for? (video, ~8 mins)

• A quirky, almost NSFW video by Heydon Pickering, explaining when and why to add ARIA roles and attributes to your HTML. It is best used when there is no good native HTML solution to your problem. For example, a ‘toggle button’ could be achieved with checkboxes, but is difficult to style and would be announced as input to the screen reader: better to use <button aria-pressed="false">Toggle</button> and use JavaScript to change the aria-pressed value. And <button> already has an implicit role="button", so there is no need to add it here.
