Accessibility Guidelines Summary

This document provided by Kin + Carta Create will help you quickly get up to speed with the Web Content Accessibility Guidelines (WCAG) 2.1, and avoid common accessibility mistakes.

It only covers Level A and Level AA requirements, which are referenced in public sector procurement laws in the UK, US public sector procurement laws, EU public sector procurement laws and public sector procurement laws around the world.

These guidelines apply to both native apps and web-based apps, except for three which are labelled Web only.

This summary is a simplification. If you're not sure how a guideline applies, check the official WCAG 2.1.

1. Easy to perceive

Your website/app must present information in ways that people can recognise and use, no matter how they consume content (for example if they have low vision, or use assistive technologies like screen readers).
