For the web to be truly accessible to people with disabilities, multiple components of web development and interaction must work together seamlessly. This includes content, user agents (like browsers), assistive technologies, developers, and authoring tools.

The Web Content Accessibility Guidelines (WCAG) are developed through the W3C process in collaboration with individuals and organizations worldwide. The goal is to establish a single, shared standard for web content accessibility that meets the needs of individuals, organizations, and governments across the globe.
