HTML <html> Tag
The <html> tag is a root element of an HTML document. It contains all HTML elements, which inform the browser that this is an HTML document. Before the <html> tag we must put only the <!DOCTYPE> declaration, which inform about HTML version used in the document.
The child elements of the <html> tag are:
- The <head> tag contains technical information for browsers enclosed in <title>, <script>, <link> and other tags).
- The <body> tag defines the content of HTML document (text, images, links, etc.).
We recommend using the <html> tag with the lang attribute, which defines the language of the document. It simplifies the indexing of a web page by search engines, helps browsers to correctly display national characters and devices that read from the screen, to correctly determine the pronunciation.
The <html> tag comes in pairs, the closing tag (</html>) is required.
