Accessibility ensures that people with disabilities can use Xello. This includes compatibility with assistive technologies like screen readers.

Xello has been designed and developed to be compatible with the following standards:

Core components of accessibility
A myriad of techniques have been implemented to make Xello accessible. Here are some of the main pillars of our accessibility strategy:

  • Color contrast and font sizes meet the standards described in WCAG 2.2 Level AA
  • 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:

  • VoiceOver in Safari on Mac and iOS
  • JAWS in Internet Explorer on Windows
  • ChromeVox
noteNote: Other screen readers will also work with Xello if they are compliant with the standards listed above.
