Advanced Shadow Generator Studio
Build layered CSS shadows visually, tune every layer precisely, compare light and dark surfaces, and export clean production-ready code.
Create more convincing depth than a single basic shadow. Stack multiple shadow layers, tune each one visually, test different surfaces and copy clean CSS when the result feels right.
About This Tool
Advanced Shadow Generator Studio is a visual workspace for building layered CSS box shadows. Each shadow layer has independent horizontal and vertical offsets, blur, spread, color, opacity, inset mode and visibility. Combine subtle ambient shadows with tighter contact shadows, duplicate layers to iterate quickly, or start from practical presets such as Soft, Floating, Material, Dramatic, Neon, Inner, Card and Crisp. The live preview supports card, button, circle and image-style objects on both light and dark backgrounds. When the shadow system is ready, copy the box-shadow declaration, a CSS custom property, a complete CSS rule, the selected layer or structured JSON data.
How to Use
- Choose a preview object and a light or dark background.
- Select a shadow layer, then adjust its X and Y offsets, blur, spread, color and opacity.
- Enable Inset when you want an inner shadow, or disable a layer temporarily without deleting it.
- Add or duplicate layers to build more natural depth, or apply a preset as a starting point.
- Review the live CSS output and copy the format you need.
Example
Start with the Card preset, keep the soft ambient layer, reduce the second layer to 8px blur and 10% opacity, then compare the result on light and dark backgrounds before copying the final box-shadow declaration.
Frequently Asked Questions
Why use multiple shadow layers?
Different layers can represent different parts of perceived depth, such as a broad ambient shadow and a tighter contact shadow. Layering gives you more control than one large blur.
Can I create inset shadows?
Yes. Every layer has its own Inset option, so outer and inner shadows can be combined in the same stack.
How many shadow layers can I add?
The studio supports up to eight layers, which is enough for complex effects while keeping the workspace manageable.
Can I temporarily hide a layer?
Yes. Toggle an individual layer off without deleting it, or use Disable All to compare the object with and without shadows.
What export formats are available?
You can copy a box-shadow declaration, CSS custom property, complete CSS rule, selected layer value or JSON representation of the layer stack.
Does the tool send my design data anywhere?
No. Shadow editing and code generation happen entirely in your browser.
