Common questions
Why does the shadow look different in my app?
Background colour, border radius and stacking context all affect perception. Always check on the real component.
Can I layer multiple shadows?
Yes. Comma-separated shadows are drawn front to back and are the usual way to get realistic depth.
Are shadows expensive to render?
Large blurred shadows can cost paint time, especially during animation. Animate transform or opacity instead.
