HTML Meta Information Automatic Refresh
Example
To refresh the page every five seconds, add this meta element in the head element:
<meta http-equiv="refresh" content="5">
CAUTION! While this is a valid command, it is recommended that you do not use it because of its negative effects on user experience. Refreshing the page too often can cause it to become unresponsive, and often scrolls to the top of the page. If some information on the page needs to be updated continuously, there are much better ways to do that by only refreshing a portion of a page.
