How to define the language of the page?
Add a lang attribute to the html element with a valid language code.
For english this would be:
<html lang="en">
<!-- content -->
</html>
Valid language codes are either two-letter or three-letter language codes. You can find the list of valid language codes in the ISO 639-1 code list.
Why is this important?
The use cases for the <html lang> attribute are:
- Screen readers
- Translation such as Google Translate
- Spellchecking
- Localized date and time input
It is crucial to define a valid lang attribute on the html tag.
A screen reader uses the lang attribute to select the corresponding language to speak the text if that language is available.
