Basically you may find the template in the /templates/revolution folder. The index.php contains the html code, and in the /templates/revolution/css/ folder you will find the css which controls the styles. There is one more thing. In the /templates/js/ folder you may find a javascript file called hover.js. This file controls the gradual hover effect of the left sideblock and of the YOUR BAG in the top.
Hope this helps.
