How this tool helps you
The CSS Box-Shadow Generator removes the guess-work from styling shadows. Instead of tweaking numbers in your editor and refreshing the browser, you get an instant visual feedback loop that works on phones, tablets, and desktops alike.
Speed: All calculations run locally in your browser, so there’s zero server delay. The page weighs under 30 kB after gzip, so it loads in milliseconds even on 3G.
Precision: Each slider snaps to whole pixels, and the color input supports alpha transparency. Need multiple layered shadows for neumorphism or glow effects? Switch the “Multiple Shadows” dropdown and watch the code update.
Workflow: Once you’re happy with the look, click “Copy CSS” to place the rule in your clipboard, or “Download CSS File” to save a ready-to-drop-in stylesheet. No frameworks, no build step—just pure, production-ready CSS.
Stop hand-coding shadows and start designing them.
