Automatic redirect

Sometimes your webpage needs a automatic redirect.

For example, to redirect to example.com after 5 seconds:

<meta http-equiv="refresh" content="5;url=https://www.example.com/" />

This is line will send you to the designated website (in this case example.com after 5 seconds.

If you need to change the time delay before a redirect, simply changing the number right before
your ;url= will alter the time delay.
