Users with learning disabilities may use assistive technology, including browser add-ons and extensions. All of your content should work with these tools, support a personalized interface, and allow for simplification. Users should also be able to control when content changes.
Besides following the best practices outlined in the WCAG standards, Davies shares several other "useful things to remember and easy gotchas."
"The easiest way to make tools more accessible is by using colours with enough contrast," she advisers. "Avoiding using red and green to highlight pass/fail, look at ways to other colours or find other ways to highlight this."
"Check your application works with a screen reader," adds Davies. "can people still learn and know what's going on without being able to see the page?"
