The CSS Playground provides an interactive visual workbench for testing and generating modern CSS layout and styling properties.

Instead of guessing syntax values in code editors, developers and designers can tweak visual sliders and immediately inspect rendered layout behavior.

### Four Integrated Design Studios 1. Flexbox Studio: Test flex-direction (row, row-reverse, column, column-reverse), justify-content (center, space-between, space-around, space-evenly), align-items, flex gap, and item counts. 2. Grid Studio: Configure grid column tracks (1 to 6) and gap spacing with live cell rendering. 3. Box Shadow Studio: Build elevation effects by adjusting horizontal offset, vertical offset, blur radius, spread, and opacity sliders. 4. Glassmorphism Studio: Design frosted-glass cards with backdrop-blur filters, semi-transparent background fills, and subtle border highlights.

### Concrete Styling Example Switch to the "Shadow" tab. Set vertical offset to 15px, blur radius to 30px, and opacity to 0.25. The preview card displays soft elevation depth and generates: `box-shadow: 0px 15px 30px rgba(0, 0, 0, 0.25);` ready to copy directly into your stylesheet rules.

### Processing and Privacy All styling controls and CSS code generation execute client-side in your web browser. No design tokens or style definitions leave your computer.
