Frontend developers have to consider many things: browser compatibility, usability, performance, scalability, SEO, and other best practices. But the most fundamental aspect of creating websites is one that often falls short: accessibility. Accessibility is the cornerstone of any website, and if a website is inaccessible, users won't be able to interact with it, obtain information, sign up for services, or buy products. The Web Accessibility Cookbook provides you with dozens of recipes to help you avoid these failures. You'll learn how to build common components, such as main navigation, filters, and dialogs, in an accessible manner. Each recipe not only explains how to build things but also why. Author Manuel Matuzovic provides the knowledge you need to create your own accessible components and address your users' varying needs, abilities, and preferences. What makes accessibility technically interesting, besides its human nature, is its complexity, range, and interrelationship with other disciplines on the web. To make accessible websites, you need a core knowledge of user interaction (UI) design, user experience (UX), usability, performance, content strategy, search-engine optimization (SEO), and security. This book is for anyone who writes front-end code: front-end developers, UX engineers, full-stack and back-end developers. It doesn’t matter if you’re new to web development or have been writing HTML, CSS, and javascript for over a decade. You want to learn how to structure pages and components with HTML and how semantic elements affect user experience. You know CSS and want to learn how to style your websites in a way that serves your users. You are interested in ARIA and how to use it efficiently to improve the experience of interactive components written in javascript.
