How can I add an intro like this website?

Site URL: https://www.justinbordeaux.com/

Well, the title speaks for itself. TIA :)

Nice Site built on Rackspace. The opening is a simple animated text and auto trasition to main page, this is the closet thing to it that I could come up with:

This would go into the advanced header of the home page and the url of the  page it trasitions to would go where  "http://www.link-to-main-page.com/" is. 

<meta http-equiv="refresh" content="3;url=http://www.link-to-main-page.com/"
 transform  :fade

transition :2.0s />
