Accessibility with screen readers

Hi there,

I was wondering if anyone knew how to improve the user experience of Popup Builder for someone using a screen reader (JAWS, etc)? If the popup opens, a JAWS user won’t get a prompt to tab into the content of the popup, they will have to do that on their own accord. I was wondering if there’s a setting or a piece of Javascript or CSS that would help focus a screen reader to the content inside of the popup automatically? The popup I am testing just has a nested iframe of an email sign up list. Any insights are greatly appreciated! Thanks – R
