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.
