The World Wide Web Consortium (W3C), the global organization that sets standards for accessible content, has announced a new standard that will help Web designers and developers create sites that better meet the needs of users with disabilities and older users. Known as Web Content Accessibility Guidelines 2.0, it allows for websites, text, images, audio and video to be more precisely tested for accessibility while giving Web developers more flexibility.
WCAG 2.0 addresses barriers to accessing the Web experienced by people with visual, auditory, physical, cognitive and neurological disabilities, and by older Web users with accessibility needs. WCAG 2.0 advises how developers should make their content easier to use, such as by adding text alternatives for images, captions for audio and color contrast. The guidelines also suggest addressing keyboard access and avoiding too-quick movements, such as those that are Flash-based, which can cause seizures.
