Introducing Box Shadow Generator

Box Shadow Generator is now live on Tools.Town — a visual tool to design CSS box-shadow values with sliders for offset, blur, spread, color, and opacity, with a live preview element you can inspect in real time.

No more trial-and-error in DevTools. Build the shadow you want, then copy the CSS.

What Does It Do?

Outer Shadow

Classic drop shadow outside the element. Control X/Y offset, blur radius, spread, and color independently.

Inner Shadow

Inset shadow drawn inside the element boundary — great for pressed states, input fields, and depth effects.

Multi-Layer

Stack multiple shadows in one rule. Combine a soft ambient shadow with a sharper contact shadow for realism.

Shadows use rgba() colors so you control opacity separately from the color — the generated CSS reflects this exactly.

How It Works

Adjust sliders

Set X offset, Y offset, blur, and spread with range sliders. Positive Y offset casts the shadow downward.

→

Pick a color

Choose the shadow color and adjust opacity. Use a slightly tinted shadow (not pure black) for a natural look.

→

Add more layers

Click Add Shadow to stack multiple shadow layers for richer depth effects.

→

Copy the CSS

Click Copy and paste the complete box-shadow property into your stylesheet.

Why We Built It

Box shadow is one of those CSS properties where the numbers don’t map intuitively to what you see. Knowing that 0 4px 6px -1px rgba(0,0,0,0.1) is “a standard card shadow” requires experience. This tool makes the relationship between values and appearance visible, so designers and developers can explore and learn while building.

Frequently Asked Questions

Can I add multiple box shadows?

Yes. CSS allows comma-separated shadow layers. The generator lets you stack multiple shadows to build depth effects.

What's the difference between inset and outset shadows?

Outset shadows appear outside the element boundary. Inset shadows are cast inside the element, creating a pressed or embossed effect.

Does the output work in all modern browsers?

Yes. box-shadow is supported by all modern browsers with no vendor prefixes needed.
