WCAG in Plain English

Blocks of text (like paragraphs) must have a line height of at least 1.5, not be justified, and stay within 80 characters (or 40 for CJK scripts). Allow users to adjust spacing and colors using custom styles.

Text must be actual text, not images of text (no exception, not even for design or aesthetic reasons).

Interactive controls (e.g. buttons, form fields, focus indicators) and graphics that convey meaning (e.g. icons, charts, graph lines) must have a contrast ratio of at least 3:1 against adjacent colors.

Text remains readable and usable when spacing is changed using custom styles to at least 1.5× line height, 2× spacing after paragraphs, 0.12× letter spacing, 0.16× word spacing, without content being hidden, cut off, or broken.

When additional content appears on hover or keyboard focus (including long press on touch), it must stay visible until dismissed or no longer valid, be dismissible (e.g. using the key), and remain visible when hovered or focused.

All functionality must be operable using a keyboard alone, unless the task requires freehand input (e.g. drawing).

It must always be possible to move focus into and out of any component using a keyboard alone (e.g. [tab], [shift] + [tab], [enter], [esc]), without getting stuck.

All functionality must be operable using a keyboard alone (no exception, not even for tasks involving gestures like drag-and-drop or pointer-based interaction).

Time limits must be avoided unless essential for the task (e.g. exams, auctions). If time limits are used, it must be possible to turn them off, adjust them to at least 10× the default, or extend them by at least 10×.

If content moves, scrolls, blinks, or updates automatically for more than 5 seconds, it must be possible to pause it, stop it, or hide it.
