The <html> tag is a root element of an HTML document. It contains all HTML elements that inform the browser that this is an HTML document. Before the <html> tag we must put only the <!DOCTYPE> declaration, which informs about the HTML version used in the document.
The child elements of the <html> tag are:
- The <head> tag which contains technical information for browsers enclosed in <title>, <script>, <link> and other tags).
- The <body> tag which defines the content of an HTML document (text, images, links, etc.).
The <html> tag comes in pairs. The content is written between the opening (<html>) and closing (</html>) tags.
Example of the HTML <html> tag:
<html lang="en"> <head> <title>Title of the document</title> </head> <body> The content of the page </body> </html>
