Definition and usage

The meta element provides meta-information about the page, such as descriptions and keywords for search engines and update frequency.

The meta tag is located at the head of the document and does not contain any content. The attributes of the meta tag define the name/value pairs associated with the document.

Differences 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 had to write:

<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1">

In HTML 5, this is enough:

<meta charset="ISO-8859-1">
