Need CSS for the account details "customer page"

Hello Team,
I need help, i use the ecommerce Quark; so need a CSS for enjoy the Account page of virtuemart component.
This page does not benefit from a CSS at the height of the whole template and that is responsive on mobile too.

Indeed, on this page, we can modify the information related to the customer, the delivery addresses, ect ... but the problem is that we can not clearly distinguish the links. Instead of the buttons, there are links without any cladding. This really is not clean.

Thank you for your help

Hi
