content-type Specifies the character encoding for the document.

Example:

<meta http-equiv="content-type" content="text/html; charset=UTF-8">

default-style Specified the preferred style sheet to use.

Example:

<meta http-equiv="default-style" content="the document's preferred stylesheet">

Note: The value of the content attribute above must match the value of the title attribute on a link element in the same document, or it must match the value of the title attribute on a style element in the same document.

refresh Defines a time interval for the document to refresh itself.
