Overview
On certain mobile devices, users might be able to scroll the UpCart horizontally, exposing an unintended white space on the right. This usually occurs when a child element within the cart exceeds the viewport width or disrupts the layout’s natural constraints, resulting in horizontal overflow.
CSS Solution
To prevent this behavior and keep the cart constrained to the viewport width, simply copy the code below and add it to the following directory:
Cart Editor > Settings > CSS
.upcart-cart-body
{
overflow-x: hidden !important;
}
