Module 7: Checkpoint 7—Browser support

Conformance: Mandatory


Agencies must provide video formats that support all browsers on the full browser support list.

Benefits of conformance

  • Cross-browser testing ensures videos remain usable on the majority of browsers used.
  • Agencies can focus resources on testing common browsers, not all browsers.

Risks of non-conformance

  • Videos may not remain usable on different browsers or devices, negatively affecting the user experience and accessibility of the web resource.
