Align add to cart and quantity

Hey @marknadsforingsbyran,
There are margins applied on both the buttons.
Add the below CSS code in Appearance->Customize->Additional CSS:

.single-product .quantity {
    margin-bottom: 0px !important;
}

.single-product .single_add_to_cart_button {
    margin-top: 0px !important;
}
