Readers who develop, administer, or create content for websites may want to check out this Google Developers resource on the fundamentals of web accessibility. Here, readers will find the first page of a set of web documents comprising a "concise treatment of [web] accessibility principles and practices." This page serves as an introduction to the concept of web accessibility and its importance, as well as an overview of the rest of this guide, which is "intended to help you understand how you can make your websites accessible and usable for everyone." The pages that follow introduce readers to building content that can be navigated via keyboard rather than a mouse, writing semantics into web pages so that they are compatible with assistive technologies, and styling visual elements so that they are flexible and usable for everyone. This introductory guide is conversational in tone and is accompanied by illustrative images and helpful links to further information. This resource was written by Google Tech Writers Meggin Kearney and Dave Gash with contributions from Alice Boxhall and Rob Dodson.
