HTML <html> Tag

The <html> tag is a container for the entire page.

The exeption is <!DOCTYPE>, which must be the first line in a page.

This tag tells the browser that the current page is an HTML document.

Example

#

An <html> container with two child elements: <head> and <body>.

<!DOCTYPE html>
<html>
  <head>
    <!-- meta data -->
  </head>
  <body>
    <!-- page content -->
  </body>
</html>	

Notice that !DOCTYPE is outside the <html> container.


Using <html>

The <html> element serves as a container for all HTML elements -- except <!DOCTYPE>.

A page can only have one <html> tag.

More Examples

Nested inside are the <head> and <body> tags, which, in turn, have their own nested tags.

 </head>
