This visual CSS utility designs realistic box-shadow elevation effects using interactive offset, blur, spread, and color controls. Web developers, UI engineers, and design system creators can craft subtle surface drop shadows, floating modal card elevations, and inset effects without hand-typing CSS parameter strings.

### Shadow Geometry and Property Parameters The generator provides fine-grained controls for each CSS `box-shadow` component:

- **Horizontal Offset ($X$):** Moves the shadow horizontally (range: $-50\text{px}$ to $+50\text{px}$). Positive values cast rightward; negative values cast leftward. - **Vertical Offset ($Y$):** Moves the shadow vertically (range: $-50\text{px}$ to $+50\text{px}$). Positive values cast downward. - **Blur Radius:** Softens the shadow feathering (range: $0\text{px}$ to $100\text{px}$). Higher values simulate greater distance from the light source. - **Spread Radius:** Expands or contracts the shadow footprint (range: $-50\text{px}$ to $+50\text{px}$). - **Color & Alpha Channel:** Custom hex/rgba color picker for realistic ambient shading (defaults to `#00000033`, corresponding to 20% black).

### Practical Elevation Example Suppose a developer creates a floating card hover elevation: - **X Offset:** 0px - **Y Offset:** 8px - **Blur Radius:** 24px - **Spread Radius:** -4px - **Shadow Color:** `#00000026` (15% ambient opacity)

**Generated CSS Property:** ```css box-shadow: 0px 8px 24px -4px #00000026; ```

### In-Browser DOM Rendering All shadow rendering updates in real time on a live card preview using native browser rendering. No styling code or design tokens leave your device.
