W3C HTML5 Validator enhanced with language detection functionality
The W3C HTML5 Validator has been enhanced with functionality that detects the overall language of a page. The validator can currently detect a little over 50 languages, but more will be added over time.
This makes it possible to compare the language of the content in a page with language declarations, and issue warnings if the lang
attribute does not match the language of content, if no lang
attribute is given at all, or if a language using a right-to-left script is detected but a dir
attribute is missing from the html
tag.
For more information on the lang
attribute, see the Why use the language attribute? article, or Declaring the overall language of a page in the technique index.
