I found a thread discussion on changing the woocommerce cart to a two colum format using flex box. Works great! However, when update cart is pressed, the cart page goes back to its default format. All custom CSS to create the two column format is lost.
It seems that many people want the two column cart format, but I can’t find any threads that go to a complete solution.
Screen shots included (ignore the horrible colors, using those to make sure my selectors are correct)
