<html> Root Element
The container for the entire document.
1The Root
The <html> tag wraps every other element. Always set the lang attribute so screen readers and search engines know the language.
Example Code
css
<!DOCTYPE html>
<html lang="en">
<head>...</head>
<body>...</body>
</html>2Put the element in context
The root html element contains the document’s head and body. Its language attribute helps assistive technology and other tools interpret the main text. A fragment copied into a component does not need another root html element, but a standalone downloaded page does.
3Practice with a small page
Build a full standalone page with a suitable lang value. Inspect the document tree and locate the head and body. Mark a phrase in another language separately rather than changing the entire page language for a single sentence.
