Use interim accessibility solutions so that assistive technologies and older browsers will operate correctly. Older browsers do not allow users to navigate to empty boxes. Older screen readers read lists of links as a single link. And changing the current window or popping up new windows can disorient users who cannot see that this happened.
Checkpoints:
10.1 – Do not cause pop ups or other windows to appear without notifying the user
10.2 - Support explicit associations between labels and form controls, for all form controls with implicitly associated labels; ensure that the label is properly positioned
10.3 - Render side-by-side text correctly. Be sure to provide a linear text alternative on a current page or in some other form for all tables that lay out text in parallel, word-wrapped columns.
10.4 - Handle empty controls correctly, include default, place-holding characters in edit boxes and text areas
10.5 - Create adjacent links distinctly, include non-link, printable characters that are surrounded by spaces between adjacent links
The document stated how these checkpoints may not be necessary in the near future. But for right now they are considered to be an important part of the accessibility standards. So I’m not sure if I would put too much effort into any of these except maybe having windows pop up that the user is unaware of. For more details or to visit the information source site click here.
