For an excellent discussion of modals and how to make them more accessible, see https://www.tpgi.com/the-current-state-of-modal-dialog-accessibility/ Sent from my iPhone On Jun 11, 2021, at 5:14 AM, rasmussen.bryan@gmail.com wrote: (imagine a screen reader user who can't actually see where the modal starts/ends ... they'll just navigate through it and, without knowing it, navigate out and close it). I'm imagining it functioning the way a lot of modals do when you click on the modal overlay ('outside' the modal) and the modal closes, I would expect of course to have track the navigation to know the user had left the modal and be able to give them information the modal they were in was now closed.

That seems sort of weird to me since I would normally just think I allow you to tab out and when you do I close the modal and give your the focus outside the modal to wherever you are at (same applies popup) - at first I thought well ok that's the way the ADA wants it but the more I thought about it the more it seems just wrong to me. So is the way I would normally do it correct or was the article actually correct that the ADA would require you to prevent the user from tabbing out of such a container? If so, can you clarify the reasoning for me? The ADA itself doesn't go into such deep technical detail, so it's best to avoid statements like "the ADA rules require...", and more specifically referencing WCAG or Section 508 or similar that actually touch on technicalities... Generally, for modal dialogs, there is ideally an expectation that focus will be contained inside the modal until the user explicitly closes it. See https://www.w3.org/TR/wai-aria-practices-1.1/#dialog_modal If the modal auto-closes if you tab out of its bounds...not 100% sure it would be a hard failure of WCAG (e.g. under 2.4.3 Focus Order https://www.w3.org/TR/WCAG22/#focus-order), but it's certainly unexpected and likely not good usability (imagine a screen reader user who can't actually see where the modal starts/ends ... they'll just navigate through it and, without knowing it, navigate out and close it). Popups/tooltips are slightly more controversial. Some people see them as tiny modal dialogs, while others look at them more like disclosure widgets or similar where focus should not be contained. It often depends on the amount of information/controls and type of popup. P -- Patrick H.
