Accessibility Patterns for the Web
Last Updated: June 13th 2018
This book will assist frontend developers in building accessible e-commerce websites and components.
This book is not a visual design system or a CSS framework (à la Bootstrap) - it is instead intended to complement those systems & tools.
This book is a living, work-in-progress document. Some patterns are complete, but gaps in the documentation still remain. We are addressing these gaps as quickly as we can.
These patterns will assist developers with accessibility, but are not considered to be final, production ready code!
There are 4 main groups of patterns:
These groups spell out the MIND acronym. If you ever wonder what group does a pattern fall into - then use your MIND!
Every pattern includes:
- Working examples
- Best practices
- Interaction design
- Developer guide
- ARIA Reference
There are 4 guiding principles of accessibility, collectively know as POUR:
- Perceivable: People experience content in different ways (sight, hearing, and touch). Content needs to be transferable into recognizable (or perceivable) formats.
- Operable: Content needs to be navigable (or operable) by multiple methods—not just a mouse
- Understandable: Web content needs to be understandable. Language should be simple and concise; functionality should be consistent and intuitive.
- Robust: Create web content that works for all (or most!) technologies. This includes operating systems, browsers, and mobile devices.
From a developer perspective, Operable and Robust are the most important principles!
