The practice of making sure that websites and digital tools are accessible for all users including those with disabilities is important, but developers new to thinking about accessibility may need a helping hand to get started. This free online course provided by Google on the Udacity platform offers just that. This course begins its six self-paced lessons by explaining "when and why users need accessibility" before digging into the three pillars of accessibility (focus, semantics, and style) and the how-tos of their implementation. For example, students will learn how to make it possible for site visitors to navigate a page using a keyboard rather than a mouse, how to add semantic HTML and ARIA markup to enable accessibility with a variety of assistive devices, and "styling techniques that help users with partial vision navigate your pages easily and reliably." An estimated two weeks in length, the course includes videos, exercises, interactive quizzes, and is instructed by professional developers Alice Boxhall, Rob Dodson, and Michael Wales. This is an advanced course, so learners should be familiar with HTML, CSS, and Javascript, and registration for a free Udacity account is required.
