Advanced Accessibility Training


We're excited you're continuing your learning about digital accessibility. Making accessible content means equal access to education and employment, the services we provide, and above all, the Western experience. We can do our part by factoring accessibility into each step of creating digital content—from planning to publishing.

This training will cover:

  • What the document object model (DOM) is and how it relates to the accessibility tree
  • Advanced accessibility features and tips for HTML, CSS, and JavaScript
  • Accessibility-specific technologies like Accessible Rich Internet Applications (ARIA) and manual testing techniques.
