This book will assist frontend developers in building accessible e-commerce websites and components.

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!

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!
Accessibility testing is performed with latest versions of:
Edge & Narrator
Internet Explorer & JAWS
Safari & VoiceOver
