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).

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.

Content must not include time limits for reading or interaction, unless it’s part of a live event or time-based activity (e.g. auctions, broadcasts).

Interruptions (like pop-ups, alerts, or notifications) must be able to be delayed or suppressed, and controlled, except in emergencies (e.g. critical system warnings).

When (re-)authentication is required (e.g. after session timeout), all previously entered data must be preserved so the task can continue without starting over.
