Invalid language attribute on html tag for languages such as en_wp and de_kids

XMLWordPrintable

    • WP Sprint 2023-I4.2 (Clones)

      This issue was detected during accessibility audit on learner-facing pages in Workplace performed in August-September 2023 by AbleDocs.

      Invalid Language attribute

      The LANG attribute "en-wp" is not valid as "wp" is not a valid ISO country code

      By setting the appropriate language attribute it allows screen readers to pronounce words correctly

      Recommendation from AbleDocs:
      Set to a valid English subtype, en-AU or en-CA for example. If this website may be used in multiple countries either set the LANG to just "en" or have it determine the country code per organization

      List of valid languages: https://www.w3docs.com/learn-html/html-language-codes.html
