Change text size on message in cart

Hi, I am new user of this plugin. I would like to change the size of message text in cart (I know how to change the text size in progess bar). But when you stand on cart, I would like to be able to change textsize or make it bold. On my page it is small and not easy to see. If it is not a possibility today, perhaps it can be a feature. See

Otherwise I look forward using this plugin.
