- Interface Structure:
- Left Sidebar: Control panel for individual shadow layers (Add/Delete/Reorder buttons).
- Center Preview: A large responsive canvas containing a 'Sample Element' that updates dynamically.
- Right Panel: Read-only code output block with a 'Copy to Clipboard' function.
Interactive Features
- Layer Management: Users can add unlimited shadow layers. Each layer contains sliders for: X-offset, Y-offset, Blur radius, Spread radius, and RGBA Color Picker.

Frequently Asked Questions
Everything you need to know about using this application.
What is a multi-layer CSS box-shadow?
A multi-layer box-shadow involves stacking multiple shadow declarations separated by commas in CSS to create complex depths, softer gradients, or realistic lighting effects on UI elements.
Why use multiple shadows instead of one?
Single shadows often look artificial. By layering multiple shadows with varying offsets, blur radii, and opacities, you can mimic natural light falloff and create a more professional, sophisticated depth.
Is this shadow generator compatible with all browsers?
Yes, standard CSS box-shadow properties are supported by all modern web browsers. The code generated is clean, semantic CSS that adheres to current W3C standards.
