Introducing the eBay MIND Patterns
This book will assist frontend developers in building accessible e-commerce websites and components.
This book is a living, work-in-progress document.
Each pattern follows a progressive enhancement strategy (where applicable), aims to conform to WCAG 2.1 Level AA, and for the most part builds on from the excellent guidance set out in the WCAG Authoring Practices.
There are four main groups of component-related patterns:
These groups spell out the MIND acronym. If you ever wonder what group does a pattern fall into - then use your MIND!
Three other important groups complement the above patterns:
We have not yet incorporated these three groups into any kind of clever or witty acronym (which is disappointing, I know).
Every completed pattern will include:
- Working examples
- Best practices
- Interaction design
- Developer guide
- ARIA Reference
The book also contains an appendix section with a list of ARIA Essentials, References, Utilities and FAQ.
There are 4 guiding principles of accessibility, collectively know as POUR:
- 1.Perceivable: People experience content in different ways (sight, hearing, and touch). Content needs to be transferable into recognizable (or perceivable) formats.
- 2.Operable: Content needs to be navigable (or operable) by multiple methods—not just a mouse
- 3.Understandable: Web content needs to be understandable. Language should be simple and concise; functionality should be consistent and intuitive.
- 4.Robust: Create web content that works for all (or most!) technologies. This includes operating systems, browsers, and mobile devices.
Accessibility testing is performed with latest versions of:
- Chrome & JAWS
- Firefox & NVDA
- Safari & VoiceOver
