  • Captioning for all audio and video content
  • Full keyboard accessibility
  • Use of ARIA-live regionsnew tab for screen readers

Screen Readers

All screen readers that support the above standards are compatible with Xello. To verify that we are meeting these standards, we test with the following screen readers:
