Frequently asked questions
What do the four box-shadow lengths mean?
In order they are the horizontal offset, the vertical offset, the blur radius and the spread radius. Positive offsets move the shadow right and down; spread grows or shrinks the shadow before blurring.
How do I make a shadow look more natural?
Combine two or more layers: a small, sharper shadow close to the element and a larger, very transparent, blurred shadow further away. Keep opacity low (5–20%).
What is an inset shadow?
An inset shadow is drawn inside the element's border instead of outside, which makes the element look pressed in. It is commonly used for input fields and neumorphic designs.
