Adjust the cart page (responsive)

Hi,

I can’t for the life of it figure some css stuff out.

Firstly on a small screen I get horizontal scrolling because of the product table or the buttons in it. How can I change that? I can’t even change the width of the coupon input field.

Secondly, how can I position the cart total tabel? I see the corresponding divs and all but I can’t move the tabel freely in it. I managed to shift it over to the half of the page but that’s not what I want.

Here is the page: Shop Cart

Would really appriciate some help here.
