hi! there is a small black line around half the buttons of ‘add to bag’ and ‘checkout’ (when there is a product in your bag). I want these lines to be removed, it only dissapears when i hold my cursor on the buttons now…

add this CSS code and it will fix your issue:

.button:after {
    box-shadow: none !important;
}

where exactly?
