HTML Language Attribute Checker

Check if your webpage uses the correct lang attribute in the HTML tag.

What Is the HTML Language Attribute?

The lang attribute inside the <html> tag defines the language of your web page. For example:

<html lang="en">

📌 Use ISO 639-1 codes (e.g., en for English, fr for French, es for Spanish)
📌 For regional variants, use values like en-US or en-GB
📌 Always declare it on the <html> tag

Ensure every page on your website has the correct lang attribute to improve accessibility, usability, and global reach.
