The CSS box-shadow property attaches one or more shadows to an element. Creating realistic, soft shadows often requires stacking multiple layers of shadows with different offsets, blurs, and opacities to mimic natural lighting.
How to use this tool:
- Use the sliders to adjust the horizontal (X) and vertical (Y) offsets, blur radius, spread radius, and shadow color.
- Enable the Inset checkbox to render the shadow inside the frame rather than outside.
- Add multiple shadow layers to build realistic, soft neumorphic or ambient shadows.
- Copy the complete CSS declaration instantly.
// frequently asked questions
Why should I stack multiple box-shadow layers?
Single-layered box shadows often look harsh and artificial. Stacking 2 to 5 layers of shadows with varying blur and opacity values creates a much softer, more natural gradient that mimics how light diffuses in the physical world.
What is the difference between blur and spread in box-shadow?
Blur radius controls how soft and fuzzy the edges of the shadow are (larger values mean softer shadows). Spread radius controls the size of the shadow source; positive values expand the shadow, while negative values contract it.
Can box-shadow be applied inside an element?
Yes. Adding the <code>inset</code> keyword to the CSS property changes the shadow from an outer shadow (drop shadow) to an inner shadow, making the element look like it is pressed down or recessed into the background.
