An international community develops open standards for the World Wide Web with the goal of promoting its evolution and interoperability. Founded in 1994 by Tim Berners-Lee, the inventor of the World Wide Web, the World Wide Web Consortium (W3C) is the main international standards organization for the World Wide Web. The W3C is made up of member organizations from around the world, including industry leaders, academic institutions, and government agencies. As of March 2026, W3C has 331 members.
Working Groups
The W3C’s work is divided into various working groups, each focused on a specific area of web technology, such as HTML, CSS, and accessibility.
- HTML: The HyperText Markup Language Working Group develops and maintains the HTML standard, which is the foundation of web content.
- CSS: The Cascading Style Sheets Working Group creates standards for CSS, which controls the presentation of web content.
- Accessibility: The Accessible Rich Internet Applications Working Group ensures that web technologies are accessible to people with disabilities.
Core Technologies
The W3C is responsible for developing many of the core technologies used on the web, including HTML, CSS, XML, and the Document Object Model (DOM). The W3C’s standards are widely used and respected throughout the web industry and are considered essential for creating interoperable, accessible, and reliable web content.
Resources and Tools
In addition to developing web standards, the W3C also provides a range of resources and tools for web developers, including documentation, code libraries, and testing tools. The W3C is a non-profit organization that is funded through membership fees and donations.
Leadership
The organization has been led by CEO Seth Dobbs since October 2023. W3C also engages in education and outreach, develops software, and serves as an open forum for discussion about the Web.
