Timed refresh must not exist
Since users do not expect a page to refresh automatically, such refreshing can be disorienting. Refreshing also moves the programmatic focus back to the top of the page, away from where the user had it. Such resetting is frustrating for users.
Redirection and page refresh through the use of the
<meta> element is
problematic for users with disabilities in many ways. The primary reason why redirects and
refreshes are problematic is that the user has no control over when the redirect or refresh
occurs. If the purpose of the
<meta> element is to redirect the user to a
new location, server-side means should be employed instead of client-side. Content that
moves or auto-updates can be a barrier to anyone who has trouble reading the stationary text
as quickly as well as to anyone who has trouble tracking moving objects. It can also cause
problems for screen readers.
Fixing the problem
http-equiv="refresh" attribute from each
meta element in which it is present.
To modify this example and make it accessible, remove the
http-equiv="refresh" attribute from the
<meta http-equiv="refresh" content="10" url="http://www.yourdomain.com/index.html">
If the purpose of the
<meta> element is to refresh the page, this
to provide users the ability to pause the refresh, extend the time between refreshes, or
to turn the refresh off entirely.
