Design a CSS box shadow visually with sliders for horizontal and vertical offset, blur radius, spread and color, plus an inset toggle, and watch a live preview update as you tweak each value. Getting a shadow to look just right by editing numbers blindly is frustrating, so seeing the effect immediately saves a lot of guessing. When you like the look, the tool gives you the exact box-shadow declaration ready to copy into your stylesheet. You can dial in anything from a subtle card lift to a bold neon glow, and the shadow color includes an adjustable opacity so it blends naturally. Everything runs entirely in your browser with no external requests, so it is fast, works offline, and your design experiments stay completely private.
You control the horizontal and vertical offset, blur radius, spread, color and the inset option, matching the CSS box-shadow syntax.
Inset draws the shadow inside the element instead of outside it, creating a pressed or inner shadow look.
Yes. Sliders update a preview element in real time so you can dial in the effect before copying the rule.
