Frames and scrolling divs

Frames and scrolling divs

Requirements

• Scrolling content does not cause keyboard “trapping”.
• All scrolling content can be accessed by the keyboard alone.
• All frames must be clearly labelled.

Full explanation

Developers should avoid the use of frames as they can make navigation unnecessarily difficult for keyboard and switch access users. The purpose of frames should always be described.

If scrolling Divs or frames are used then it must be possible to access all of the content using keyboard-only control. The same rule applies to any content found in multimedia applications.
