Setting the language of your site allows assistive technology to interact with your content correctly. Assistive technology will read foreign languages, but it needs to know the main language of the page and when the content’s language differs from the page’s default.


  1. Open the inspector panel.
  2. Locate the main html tag.
    • If the lang attribute isn’t set to the correct language, this is a failure.
  3. Identify any content that differs from the default language, make sure the content has its own lang attribute set with that language.
    • Any alternate language content not set constitutes a failure.
