How to Use The Science of CSS Shadows
- 1Use the 'Horizontal' and 'Vertical' sliders to position the shadow relative to the element.
- 2Increase the 'Blur Radius' to soften the shadow and make the element appear higher.
- 3Adjust 'Spread Radius' to expand or shrink the shadow size globally.
- 4Pick a 'Color' and adjust 'Opacity' to create realistic, subtle depth.
- 5Enable 'Inset' to move the shadow inside the element for a 'carved' look.
- 6Copy the generated CSS declaration and paste it into your project's stylesheet.
