toggle slide: from hide to show and not from show to hide how to?

toggle slide: from hide to show and not from show to hide how to?

Hello all. I've take a look to the example at this url about toggle slide effect:
the example, when page has been loaded, show the div and so you click button to hide the div.
I would like instead, that when the page has been loaded, the div is hide, and when i click, the div shown.
So i've try many stupid things, but nothing work. Thank you.
