HTML5 <meta> http-equiv Attribute
Example
Refresh document every 30 seconds:
<meta http-equiv="refresh" content="30" />
</head>
Try it yourself »
Browser Support
The http-equiv attribute is supported in all major browsers.
Definition and Usage
The http-equiv attribute provides an HTTP header for the information/value of the content attribute.
The http-equiv attribute can be used to simulate an HTTP response header.
Differences Between HTML 4.01 and HTML5
Using http-equiv is no longer the only way to specify the character set of an HTML document:
- HTML 4.01: <meta http-equiv="content-type" content="text/html; charset=UTF-8">
- HTML5: <meta charset="UTF-8">
Syntax
Attribute Values
| Value | Description |
|---|---|
| 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="id_of_link_element" /> |
| refresh | Defines a time interval for the document to refresh itself.
Example: <meta http-equiv="refresh" content="300" /> Note: The value "refresh" should be used carefully, as it takes the control of a page away from the user. Using "refresh" will cause a failure in W3C's Web Content Accessibility Guidelines. |
