Creating and maintaining accessible websites, applications and digital assets requires collaboration between designers, developers and content providers. In order to ensure equal access to information for all people, digital content creators should be familiar with web accessibility standards and principles. For more detailed information, view the Web Content Accessibility Guidelines (WCAG) 2.0 website.
