Help with CSS to add some titles above the fields on Cart

Hi, I need some help to add some Title fields on the Cart page screenshot - http://www.tiikoni.com/tis/view/?id=bf4515d

So above the product e.g. Portfolio add "Product" / above individual product price add "Price per print" and in the last one which is the total add "Total" Is it also possible to make sure that these are centered within their corresponding fields even on mobile devices when screen size is different ?

Please dont post any brand related information/ screenshots or domain links as i have had issues with google caching this information and linking it to their google searches of my site ... very bad for brand... please use temporary image upload / tiny url / pastebin etc to mask this information.

Thanks

Tom
