The Web Content Accessibility Guidelines 2.0 (WCAG 2.0) document, written by W3C, defines how to make web content user-friendly for all, including people with disabilities, and focuses on the principles of accessibility. When content coordinators and web developers focus on principles rather than techniques, they think about web content conceptually. WCAG 2.0's four main guiding principles of accessibility are:

Perceivable

  • Users must be able to perceive presented information

Operable

  • Components and navigation must be functional

Understandable

  • Users must be able understand presented information, as well as the operation of the user interface

Robust

  • Users must be able to access content throughout technological advances

Tips to Utilize Accessibility Guiding Principles

Perceivable

  • Provide text alternatives for images or non-text content, such as captions for multimedia

  • Create content that will not lose meaning when presented in different ways, including assistive technologies

  • Make it easy for all users to see and hear content

Operable

  • Make all functionality available from a keyboard
  • Give users enough time to read and use content
  • Use content that does not cause seizures
  • Help users navigate and find content

Understandable

  • Create readable and understandable text

  • Make content appear and operate in predictable ways

  • Help users avoid and correct mistakes

Robust
