๐ฏ Tips
- โธFor natural-looking shadows, set blur 2-3x larger than spread and use semi-transparent colors instead of solid black.
- โธLayer multiple shadows: use a small blur for the close shadow and a larger blur for the distant shadow to simulate realistic lighting.
- โธCombine an inset shadow with a regular shadow to create pressed-button or Neumorphism effects.
- โธUse a darkened version of the background color rather than pure black (#000) for more natural shadow tones.
- โธSet the Y offset larger than X offset for card elements to create a natural bottom shadow that mimics overhead lighting.
โ FAQ
Q. What is Inset?
A. Inset displays the shadow inside the box. Useful for creating pressed button effects.
Q. How do I use multiple shadows?
A. Click Add Shadow to layer multiple shadows for a 3D effect.
Q. What is the difference between box-shadow and drop-shadow filter?
A. box-shadow applies to the rectangular box model of an element, while filter: drop-shadow() follows the actual shape of the element including transparent areas. Use drop-shadow for irregular shapes like PNG images.
Q. Does box-shadow affect element layout?
A. No, box-shadow does not affect the element's layout dimensions. However, it can be clipped by parent elements with overflow: hidden, so plan accordingly.
Q. How can I optimize box-shadow performance?
A. Large blur values increase rendering cost. On mobile, reduce the number of shadow layers and add will-change: transform to leverage GPU acceleration for smoother performance.
Q. How do I create a Neumorphism effect?
A. Apply two shadows simultaneously: a light shadow (top-left) and a dark shadow (bottom-right), both using colors similar to the background. Use moderate blur and small spread values for a soft Neumorphism look.
