## Premium CSS Box Shadows
Sleek shadows add visual depth (elevation) to cards and containers. However, harsh dark shadows look unpolished.
### Tips for Sleek Shadows
- **Use layered shadows**: Combine a sharp inner shadow and a soft outer shadow for realistic ambient occlusion.
- **Low Opacity**: Use very low opacity levels (`0.03` to `0.08`) using `rgba` or `hsla` formats.
- **Increase Blur**: Use larger blur values (e.g. `20px` to `40px`) for a soft, premium appearance.
