Creating interactive web elements that everyone can use is a fundamental skill for modern web developers. Dropdown menus are common, but they often present significant accessibility barriers for keyboard and screen reader users. This text-based course guides you through the step-by-step process of building a fully accessible, robust dropdown menu from scratch. You will transition from basic markup to a production-ready, interactive element that seamlessly handles keyboard events, focus management, and screen reader announcements.
