Users of the web live with a spectrum of abilities. We need to be abundantly cautious to not create barriers to information access such as in these cases:
- Truncating essential information that either requires more interactions to view, or leaves the user stranded.
- Using colour alone to convey information that is not interpretable by colour blind individuals.
- Providing feedback after an interaction is made, but not focusing on that feedback; which is invisible to users with a screen reader or screen magnifier.
- Providing keyboard shortcuts for elements that have built-in standard shortcuts without informing the user, potentially breaking their workflow or breaking their assistive technology.
