Creating sticky-notes ( post-it )

Creating sticky-notes ( post-it )

I am designing a web page.
And i want to use sticky-notes (post-it) in my page. Where, each
sticky-note is added when we click an add button... Color of sticky notes
must change randomly, and it must be tilted and must have some hover
effect.
How can i do that ? Only CSS and HTML must be used.
I tried the code which i got from a website
http://net.tutsplus.com/tutorials/html-css-techniques/create-a-sticky-note-effect-in-5-easy-steps-with-css3-and-html5/
But, i had some part of my website as list..so when i used this code, it
also make the list items as sticky note.. i want to give property only to
a div
Thanks in advance..
