Fix styling to properly center a cover flow carousel

I have modified a cover flow demo from codepen into a Polymer element for use in a library kiosk application but can't get the centering right. Original codepen: [login to view URL] My results: [login to view URL] in [login to view URL] Notice all the covers in the screenshot are shifted right of center. The book in focus needs to be centered within the parent, and the books to either side need to be symmetric with respect to the center. Note, some intentional changes were made to fit the desired application and are OK: - no reflection or rotation - only shows 5 covers You don't really need to know about Polymer, but should be able to understand the CSS and JS in the provided github. The README has instructions for cloning and running the demo. This ABSOLUTELY needs to work in latest stable Chrome, but should work in latest stable modern desktop browsers. Please confirm you can run the demo as described in the README before bidding. Looking for a non-nonsense quick turnaround by Monday evening EDT. Possibility of other work in the near term or down the road as I need assistance.
