HTML is a language full of diverse elements, and one such element is the <html> tag. This tag, standing for ‘HyperText Markup Language’, is used to define the root of an HTML or XHTML document. It serves as the main container for all other HTML elements, excluding the <!DOCTYPE> declaration.

Understanding the <html> Tag

The <html> tag acts as the main container for all HTML elements, framing the entire web content structure. It follows the <!DOCTYPE> declaration and requires both opening and closing tags.

Syntax:

<html> HTML Contents... </html>

Default CSS

The following default values are mostly displayed by the current browsers:

html {
  display: block;
visibility: visible
}

Attribute Value:

The <html> tag includes the xmlns attribute. This attribute defines the namespace for attributes, ensuring proper interpretation and compatibility of XHTML elements.

Note: The <html> tag supports the Global Attributes in HTML.

HTML html Tag Examples

Example 1:  This example illustrates the <html> element in HTML.

<body>

Example 2: In this example, we will be using the xmlns attribute inside the <html> tag.
