Is there a way of amending the account style and layout?

Hi,

I'm having difficulty getting the account section of Membership 2 to act in a responsive way with any theme I use. I've trialled about 5 different themes but everytime I view on mobile it just looks ugly and doesn't fit on the screen very well.

Can you show me where to get at the code so I can structure the layout to work on mobile in a better way please?

Thanks,

Ash
