Box Shadow Generator
Design a CSS box-shadow visually with sliders, preview it on a card, and copy the generated CSS.
Tune shadows without guessing values
A good box-shadow is the difference between an interface that feels flat and one that feels tactile — but the five values that control it (horizontal and vertical offset, blur, spread, and color opacity) interact in ways that are hard to picture from numbers alone. This generator turns each into a slider and applies the result to a live card, so you're designing against the real thing instead of editing, saving, and refreshing.
The secret to shadows that look expensive is restraint: a large, soft blur with low opacity and a slightly negative
spread reads as a natural, floating elevation, while tight, dark shadows look heavy and dated. Nudge the sliders
until the depth feels right, then copy the ready-to-use box-shadow declaration into your stylesheet.
Copy-ready CSS
Everything is generated live in your browser — nothing is uploaded, and the CSS updates the instant you move a slider.
