Adjust the visual controls — drag sliders for shadow offset, blur radius, spread, and color with opacity; click to add gradient color stops; visually adjust border radius corners. The CSS code updates in real time as you tweak each setting.
Copy the generated CSS and paste it directly into your stylesheet. The output is clean, well-formatted, and follows CSS best practices with vendor-prefixed fallbacks where needed.

Frequently Asked Questions

Is the CSS Generator free?

Yes, completely free. Generate unlimited CSS snippets for your projects — ideal for rapid prototyping and learning CSS visually.

Are my CSS designs uploaded anywhere?

No. All generation is done locally in your browser. Your design work stays on your device.

What CSS effects can I generate and what are best practices for each?

Box Shadow is the most versatile CSS effect — use small offsets (2px–4px) with low blur and low opacity (rgba with 0.1–0.2 alpha) for subtle "elevation" cards; use larger offsets (0px 8px 30px) for dramatic depth; layer multiple shadows with commas for complex effects (neumorphism, glowing borders). Linear Gradient creates smooth color transitions — use at least two stops, add intermediate stops for multi-color effects, and specify angles (to right, 45deg) for direction. Radial Gradient creates circular/elliptical transitions — good for spotlight effects, vignettes, and background accents. Border Radius rounds corners — use border-radius: 50% for perfect circles; use asymmetric values (e.g., 16px 4px 16px 4px) for organic shapes. Text Shadow adds depth to headings — keep blur small (1–3px) for readability; avoid heavy shadows on body text as they hurt legibility.
