Soft shadow

A soft shadow has a gradual edge that fades into the background, like the one in the example. It comes from diffused light, such as an overcast sky or a room lit by a large window.

Soft shadows feel natural and quiet, which is why most interfaces use them for cards, menus and buttons.

Pro tip: a soft shadow usually needs less darkness than you think. A gentle, wide shadow often looks more polished than a strong one.
