WCAG in Plain English

Images must have descriptive alternative text.

A text-based transcription of a video is offered, on top of closed captions and audio description.

Information or relationships between content that is visual is also conveyed through the code, via HTML or ARIA (for example the for attribute on a form label, or aria-describedby on an input that has hint text).

The visual presentation of the content matches what’s read out by a screen reader.

Nothing is referred to just by its color, size, position, shape, and so on.

Rotating a device from portrait to landscape doesn’t stop everything being perfectly readable and usable.

The purpose of form fields can be identified by the browser, so that auto-complete suggestions can be offered in a dropdown.

Landmark regions and personalization semantics are used, allowing browser tools to remove non-essential content or add identifying icons to specific elements on the page.

Color must not be the only thing used to convey meaning.

Text can be resized up to 200% without loss of content or functionality, except for captions and images of text.
