Box Shadow

What is the Box Shadow?

The box shadow works like this: it tunes layered CSS box-shadows with live preview and outputs the full rule including color and blur. Everything happens on your device - the input never leaves your tab unless the tool clearly states it performs a server-side lookup.

Frequently asked questions

How do I make shadows look realistic?

Large blur + small offset + low opacity beats hard dark shadows. Stacked layers (tight shadow + wide soft one) create depth.

Why generate layered shadows instead of one?

Multiple stacked shadows with increasing blur and decreasing opacity look far more natural than a single hard shadow - realistic depth is a composite, not one rule.

What does the generated CSS include?

The full box-shadow property: offsets, blur, spread, and an rgba() colour with your chosen opacity, ready to paste into any stylesheet.
