How can I change the line-height setting on a MarketPress product?

Hi,

I have a client site that is just about to go live, and I'm working on some last minute tweaks requested by the client.

Can anyone tell me how I can change the line-spacing setting in CC for the product title on product pages?

Thanks in advance,
