Accessibility
RunTheMath.org is built to work with a keyboard, a screen reader, zoom and reduced-motion settings.
Current approach
The site uses clear headings, labelled controls, visible keyboard focus, strong color contrast, layouts that fit any screen and reduced-motion support. The question forms show one question at a time, with labelled choices and plain error messages.
Charts
Every chart has a table of the same numbers under See the numbers, and every mark shows its value on keyboard focus as well as on hover.
