3.1. Provide the primary language of the page with the lang
attribute on the <html>
tag
In order to ensure good rendering of text content, the primary language must be declared on each page.
Use the lang
attribute on the <html>
tag.
For example, for an English page use:
<html lang="en">
Tip
To populate the lang
attribute, a two-letter language code (or, if it is not available, three-letter code) must be used.
Some common codes are:
en
for English.fr
for French.es
for Spanish.de
for German.it
for Italian.
The others are available here: exhaustive list of authorized language codes.
