EU Directive on the accessibility of public sector bodies' websites•Organizations whose websites would be subject to
the new rules would have one year from the introduction of the new laws to ensure that new content added to their sites complies with the new rules;•They would have three years within which to adapt

Web accessibility is nicely standardized

WCAG 2.0•Web Content Accessibility Guidelines ─ guidelines
and techniques for making websites and web applications accessible to people with disabilities;
•WCAG consist of 4 principles and 12 guidelines and many success criteria
6
Principles•At the top are four principles (POUR) that provide
the foundation for Web accessibility: • Perceivable;
• Operable;
• Understandable;
• Robust
7
Guidelines•Guidelines are under the principles; •The 12 guidelines provide the basic goals that
authors should work toward in order to make content more accessible to users with different disabilities
9
Success Criteria•For each guideline, testable success criteria are
provided to allow WCAG 2.0 to be used;• In order to meet the needs of different groups and
different situations, three levels of conformance are defined: •A (lowest), •AA, and •AAA (highest).
