[FIX] website_sale: 40px for mobile/list view/desc

When activating the list view of product and description, if the
description was too big things were overflowing over their box and
became unreadable.

The issue is that the height limit on description was of 200px for
tablet device and there was no lower limit. Thus the limit of an product
line being 200px: the description + picture could break out of the box.

With this change, the description at lowest width devices is limited to
40px as is the case for the grid view (which is very similar on low size
devices).
