<html> element must have a lang attribute
What is the problem?
The html-has-lang rule ensures that every HTML document has a lang attribute specifying the language of the content.
Impacted Groups
Why is this important?
The lang attribute helps screen readers and other assistive technologies to pronounce words correctly, especially in languages with different pronunciations or character sets. It also helps browsers select the appropriate language-specific fonts and styles.
How to solve this issue
To fix this, add a lang attribute to the <html> element and set it to the appropriate language code, such as en for English or fr for French. This will improve the accessibility and usability of your website for users who rely on assistive technologies.
