Question about layouts

Hello all, I am kinda new to Dolphin so bare with me please.I have a site setup using dolphin 6.1 I have a theme already setup but I want to add to the look and navigation. What I am looking at is reducing the length of the page so the use would not have to scroll as much. The idea I cam up with is doing a sliding div within each column. The Something of tabs at the top of the column that when the user clicks a tab the specified content would slide into that column then if the user clicks a new tab the previous closes and the new one slides into place. Kind of like this example http://nettuts.s3.amazonaws.com/042_jQueryUITabs/demo/index.html. Would this be possible? If so, what files would need to be edited in a template to add this?

Send him an e-mail, he has the modifications to do this for you.  It's called a Page Composer and will work wonders for what you want. 

Though be advised, google likes to ding for hidden content which is what you will have if you do this to every single page and have them all collapsed as the bot comes through.
