Web accessibility (often shortened to A11y) isn't just a buzzword; it's a fundamental pillar of modern web development. As frontend developers, we hold the key to building digital experiences that are inclusive and usable by everyone, regardless of their abilities or the tools they use to access the web. This means designing and developing with considerations for people with visual, auditory, motor, or cognitive disabilities, as well as those using assistive technologies like screen readers, keyboard navigation, or voice commands.
Adhering to standards like the Web Content Accessibility Guidelines (WCAG) is crucial. WCAG provides a comprehensive set of guidelines for making web content more accessible. While the official W3C documentation is invaluable, sometimes you need practical, developer-focused resources, handy tools, and active communities to truly embed accessibility into your daily workflow.
This article compiles a curated list of over 15 must-have resources that go beyond the basics, offering deep insights, powerful tools, and practical guidance for frontend developers striving to build truly inclusive web applications.
