Thanks.
1) How do I edit the shopping cart popup?
2) How do I change the text colors on the store page?
3) How can I change the text color and background color of the active menu item (screenshot No. 1), the color of menu items (screenshot No. 2), the text color and background color of the menu item on hover (screenshot No. 3) on the account page?
Thanks.
