Re: Trapping focus in an alert

I invariably advise our clients that they should use a modal dialog i.e. trap the focus as you describe. It's particularly good for people using keyboard navigation or screen readers because it prevents them from accidentally navigating back into the page and then finding it difficult to locate the buttons again.

I suppose it's possible that there are some applications where it is critical that users do not get interrupted during a process (other than hearing or seeing the alert) but I can't think of any.

Subject: [WebAIM] Trapping focus in an alert

We have an alert that tells the user they have so many minutes remaining in their session. The alert also contains two buttons, one to continue and one to sign out. The container has a role of alert, and focus is shifted to the container when the alert is displayed. My question is whether or not to trap focus in the alert so the user cannot navigate away until they have activated one of the buttons.
