We need to implement a item preview popup to display a summary of the article along with a bigger picture. this will allow the user to place the mouse over an article an get a quick preview of the article without having to add to the cart. once page loads, the item details should be stored in memory, so it will be fast to get the item details upon mouseOver. It will also have a button to add item to the cart. should have a modern look, with rounded corners, shadow, links should change colors..
