⚡ How to Create Custom Elevation Shadows

💡 Modern UI Best Practices for Box Shadows
- Use Low Opacity Shadows: Keep opacity settings below 15-20% to achieve smooth, premium UI depth rather than harsh black borders.
- Match Accent Colors: Instead of pure black (`#000000`), tint shadow colors with your primary brand color for cohesive aesthetics.
- Layer Elevation Rules: Use higher blur radii on interactive elements like hovered buttons and modal popups to convey physical height.
❓ Frequently Asked Questions (FAQ)
Is CSS box-shadow supported on all web browsers?
Yes, standard `box-shadow` properties are 100% natively supported across modern browsers including Chrome, Safari, Edge, Firefox, and mobile engines.
What is the difference between blur radius and spread radius?
Blur radius softens and hazes the shadow edges, while spread radius physically increases or decreases the size of the shadow shape before blurring.
