Re: making a custom 404 page not found pageIf you are on an Apache service and your host permits you to add or edit the .htaccess file, add this line there:
ErrorDocument 404 /error.htm
Then, create any html page you want to be named as "error.htm" or whatever other filename you prefer.
I think it's a good idea for your visitors to make sure you include (1) full navigation links and (2) a site search function on the error page. See
http://www.psychlinks.ca/error.htm for an example and feel free to swipe what you want from that page.
You make them like any other page.
You need however to check with your provider if you can have customized error pages and if so what they should be named and where to place them.
