If you select the Color and Size of the bed on the right, and then click "Add to cart", the background will darken, a window for entering the phone number will appear and scroll page disappears.
Tell me, please, how at this moment to make sure that the scrolling of the page does not stop working?

.modal open {
overflow: hidden;
}
Delete, but this is a setting for all popups on your site
