HTML <meta> tag
Definition and Usage
The <meta> element provides meta-information about your page, such as
descriptions and keywords for search engines and refresh rates.
Differences Between HTML and XHTML
In HTML the <meta> tag has no end tag.
In XHTML the <meta> tag must be properly closed.
Tips and Notes
Note: The <meta> tag always goes inside the head
element.
Note: Metadata is always passed as name/value pairs.
Examples
Define keywords for search engines:
<meta name="keywords" content="HTML, DHTML, CSS, XML,
XHTML, JavaScript, VBScript" /> |
Define a description of your web page:
<meta name="description" content="Free Web tutorials
on HTML, CSS, XML, and XHTML" /> |
Define the last revision of your page:
<meta name="revised" content="Hege Refsnes,
6/10/99" /> |
Refresh page every 5 seconds:
<meta http-equiv="refresh" content="5" /> |
