Once triggered – do Pop-up windows capture focus and keep focus until user closes the pop-up window? Is there an option to close or escape the pop-up? Does the focus return to the last item/element to have focus on the main page before the pop-up window was triggered? Are they properly announced to assistive technology users? And are they themselves structured properly i.e., logical role, heading structure, if form, labels for inputs, and other components the create a logical flowing window for assistive technology users to navigate both within and exit out of.
- If using a link or button to open a new window or tab (either with TARGET attribute or with a script), make sure there is a label present indicating you are doing so, as those users (both screen reader and visual browsers) can be confused when they don’t realize a new window or tab is open and aren’t able to use the “back” button.
- Do not disable scrolling or resizing options – not only is it an ADA requirement but readers with low vision may need to resize content to accommodate larger text.
- When possible use a regular link as well as a pop-up link and avoid using other triggering methods – i.e., position on page, amount of time on page, etc.
