Formule & Méthode de Calcul
box-shadow: [X-Offset] [Y-Offset] [Blur-Radius] [Spread-Radius] [Color] [Inset]
You can stack multiple shadows on a single element by separating them with commas, which is essential for creating hyper realistic, diffuse ambient lighting.
Bonnes Pratiques & Conseils
- Layer Multiple Subtle Shadows: A single harsh black shadow looks cheap and dated. Professional UI design uses a tight, dark shadow for immediate depth, combined with a large, highly transparent shadow for ambient light dispersion.
- Use RGBA for Transparency: Never use solid hex colors for shadows. Always use RGBA or HSLA with a very low alpha channel (e.g., 0.05 to 0.15) so the shadow realistically blends with whatever background color sits behind it.
- Match Real World Lighting: In the real world, light usually comes from above. Therefore, your Y Offset should almost always be positive (pushing the shadow down), while the X Offset remains close to zero.
