MDN Web Docs

MDN Web Docs provides reference and learning material for web technologies such as HTML, CSS, JavaScript, and browser APIs. Its website combines explanations, examples, guides, and compatibility information.

Developers can use the documentation to understand a feature and check its reported browser support. Standards, implementations, and compatibility data change, so the actual browser and version still need appropriate verification. Documentation examples are starting points that must be adapted to the needs of a project.
