Frequently Asked Questions

Quick answers to common questions

What is the CSS box-shadow syntax?+

box-shadow: offset-x offset-y blur-radius spread-radius color; Example: box-shadow: 4px 4px 10px 0px rgba(0,0,0,0.25); Add "inset" for inner shadows.

How do I create a neumorphism shadow effect?+

Neumorphism requires two shadows — one light, one dark — on a same-colour background: box-shadow: 8px 8px 16px #b8b9be, -8px -8px 16px #ffffff;

Do CSS box shadows affect layout and performance?+

Box shadows do not affect layout. Multiple large shadows can impact paint performance on scroll, especially on mobile. Animate opacity instead of box-shadow for better performance.
