Allowing these users to adjust fonts, letter spacing, line height, and background color can be helpful. The user’s preference should also override any tilted or rotated text. Browser preferences do not have enough options to support this group, so we need to provide on-screen controls as part of a user’s individual preferences. text/html 2023-07-10T21:01:25+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.evergreen-ils.org/doku.php?id=accessibility:common_issues:disruptions&rev=1689022885&do=diff Sensory Disruptions: Flashing Lights, Animation, and Sounds Some people with photosensitivity disorders may experience headaches or seizures when viewing content that flashes or has rapidly changing colors.

Content that disappears, like toasts, should have an option to persist. (Using a standard alert message with a close or dismiss button is probably a better choice.) Content that refreshes should include a way to pause or delay the refresh.
