WebGlossary.info is a glossary for web development that extends to many related fields. It is based on the living book The Web Development Glossary by Jens Oliver Meiert (Frontend Dogma).
It currently includes 3,787 entries, some of which have several meanings. (The latest version of the book—1.1.171—may include more. Both book and website are irregularly updated. Availability and mechanics of book updates depend on where you’re buying it.)
Scope and Sources
As per the official description, “the glossary covers the major standards and concepts of the Web, beginning with HTML, CSS, JavaScript, accessibility, security, performance, code quality and testing, internationalization, localization, frameworks and editors and tooling. It then includes other disciplines of interest and relevance to the modern developer, like computer science, design, typography, usability and user experience, information and project management and more. It goes beyond web development to feed curiosity, about the Web and the technologies and processes used to build it.”
As it has been neither necessary nor desirable to provide a new explanation for every term, about 60% of the definitions are based on Wikipedia, and about 5% on MDN Web Docs. In accordance with the respective licenses, sources are attributed. All explanations are licensed under CC BY–SA 4.0. (For further information, review the legal notice.)
