Language of Page
Success Criterion 3.1.1 (Level A)


Is the language of each page properly identified in the code for your website/application?

Why is this important

Specifying the main language for the content enables user agents to present the characters accurately and assistive technologies to load the appropriate pronunciation values. This allows users of all abilities to better understand the material presented.

Whom does it benefit?

Example 1:

As a blind or low-vision user,
I want my screen reader to load the appropriate pronunciation values for the language of the content
so that I can comprehend the material presented.

Example 2:

As a person who relies on captions for synchronized media,
I want the characters in the captions to be consistent with the language of the media
so that I can understand the media content.

Example 3:

As a person with cognitive, language, or learning disabilities,
I want my Text to Speech software to pronounce the content accurately
so that I can understand the material presented.

Example 4:

As a person with reading difficulties,
I want the content presented accurately
so that I can understand the characters and symbols.

What should you do?

Ensure that each page of an application has a language (e.g. Arabic, Chinese, English) assigned to it.

How do you do it?

Look up an appropriate language code for the main language used in the application page. If an application page is in US English, the default human language should be identified as US English (en-us) by the lang attribute on the html element.
