The company that designed the web site is

They have gone to great lengths to create a tutorial that builds a web site from scratch…AND, they are cool enough to put it in a PDF file so you can download it. You can also view the site they are talking about and I believe it will cover the transitions you are wondering about.

Good Luck!

Thanks, however there was no information on what I was looking for…although the other stuff was cool… I still need help:-\

I know someone can help me :q:
