I am learning HTML and CSS … I slice and code my layouts in Photoshop, I make my rollover image code in DW that I learned from this page “http://www.webdesign.org/html-and-css/tutorials/how-to-make-rollover-buttons-using-dreamweaver-in-less-than-5-minutes.8332.html”

I can not figure out how to get that rollover code into my actual sliced layout code … Does anyone know any tutorials or how to do this ?
I can not figure out how to get the actual css code into the sliced layout code …

When I try and take the normal link and image out of the code and exchange it for the css code it makes the layout go all over the place or it just puts it above the normal button.
