HTML Attributes(3)
The lang Attribute
You should always include the lang attribute inside the <html> tag, to declare the language of the Web page. This is meant to assist search engines and browsers.
The following example specifies English as the language:
<!DOCTYPE html>
<html lang="en">
<body>
...
</body>
</html>Country codes can also be added to the language code in the lang attribute. So, the first two characters define the language of the HTML page, and the last two characters define the country.

<p title="This is my website">Lorem ipsum dolor sit amet consectetur adipisicing elit. Ut voluptas voluptatum ea tempora nisi iusto, facilis laudantium odit aspernatur sunt doloribus delectus aliquid dolorum sequi vel assumenda neque officiis explicabo.</p>
