Several step form and links

[NZ_Kiwis]

I have a process which takes server all steps, some are links some are forms.

When I go through the process I want to show a loading icon then my page, for no other reason than a visual effect.

I know hot to create the overlay in CSS and display hide items in JavaScript but how to a slow my page down to do this?

Why do some sights have this? It can't all be for visual effect?

The reason for the loading icon is usually to make sure the user is aware that the client is waiting for the server to serve something. The client displays the icon when it makes the request, and removes it when it receives the response.

So for some reason like an Ajax request?

Can you post a form via Ajax and process through a process if everything is okay?

Again posting my form is instant, how can I slow it do to have a loading affect?
