The Web Content Accessibility Guidelines
To further promote accessibility on the Web, W3C has introduced the Web Content Accessibility Guidelines ( WCAG ) Conformance Logos. Content providers can use these logos on their sites to indicate a claim of conformance to a specified conformance level of the Web Content Accessibility Guidelines 1.0 .
These guidelines explain how to make Web content accessible to people with disabilities. The guidelines are intended for all Web content developers (page authors and site designers) and for developers of authoring tools . The primary goal of these guidelines is to promote accessibility. However, following them will also make Web content more available to all users, whatever user agent they are using (e.g., desktop browser, voice browser, mobile phone, automobile-based personal computer, etc.) or constraints they may be operating under (e.g., noisy surroundings, under- or over-illuminated rooms, in a hands-free environment, etc.). Following these guidelines will also help people find information on the Web more quickly.
This guideline became a law in Germany in 2004, which means that every public website have to reach at least Level-A, described by the Guidelines. Public websites in this law means sites for example from public schools, universities or government offices.
What real consequences exist for the website developers, if they want to reach Level-A?
