Main differences in meta tag usage between HTML 4.01 and HTML 5:

In HTML 5, the scheme attribute is no longer supported.

In HTML 5, there is a new charset attribute that makes character set definition easier.

In HTML 4.01, you have to write:

XML/HTML CodeCopy content to clipboard
  1. <meta http-equiv="content-type " content="text/html; charset=ISO-8859-1">

In HTML 5, this is enough:

XML/HTML CodeCopy content to clipboard
  1. <meta charset="ISO-8859-1 "> 

Example

Define keywords for search engines:

XML/HTML CodeCopy content to clipboard
  1. <meta name="keywords" content="HTML, CSS, XML, XHTML, JavaScript" />

Define the description of the page:

XML/HTML CodeCopy content to clipboard
  1. <meta name="description" content="Free web technology tutorial." />

The latest version of the definition page:

XML/HTML CodeCopy content to clipboard
  1. <meta name="revised" content="David, 2008/8/8/" />

Refresh the page every 5 seconds:

XML/HTML CodeCopy content to clipboard
  1. <meta http-equiv="refresh" content="5" />
