A resource to help faculty create accessible digital course content, learn about digital accessibility, and meet the diverse needs of their learners.

Brief Overview of Web Accessibility

Web Accessibility: The inclusive practice of removing barriers that prevent interaction with, or access to, websites by people with disabilities (

  • This means that websites, tools, and technologies are designed for people with disabilities to use them.
  • Users should have equal access to information and functionality.
    • ADA and Sections 504 and 508 of the Rehabilitation Act prohibit discrimination of individuals based on their disability.
  • Web Accessibility addresses the needs for users in the major disability categories
    • Visual (think about screen readers)
    • Hearing (think about closed-captioning)
    • Motor (think about keyboard or alternate inputs)
    • Cognitive (think about alternate/flexible formats)

W3C: World Wide Web Consortium develops international standards for the web.

  • Accessibility is based off of the programming languages (HTML, CSS, Javascript, etc.) used to create content for the web.
  • Users of assistive technologies cannot access web content equitably if the content is not accessible.

WCAG: Web Content Accessibility Guidelines

  • WCAG 2.0 Success criteria
    • Four principles (POUR); 12 guidelines
      • Perceivable- Content must be made available to users in a format they can perceive with their senses
      • Operable- Content must be presented in a way users can interact with or operate on it with either standard or adaptive devices
      • Understandable- Content must be presented in a way users can understand or comprehend
      • Robust- Content must be presented using technologies and interfaces robust enough to allow for disability access, whether natively or in alternative technologies and interfaces
    • Conformance levels: A, AA, AAA
    • Section 508 compliance adopted WCAG 2.0 standards at the AA conformance level. This means that the most common barriers to web accessibility are removed.
    • WCAG 2.1 includes guidelines for mobile accessibility added in June 2018.
