Create glow effects with colored box-shadow
Colored shadows transform ordinary elements into luminous focal points. They simulate a light source behind the element, creating a glow or halo effect. Perfect for action buttons, prices and elements to highlight. Compose colored CSS shadows (drop-shadow, box-shadow) with custom hue, blur, spread and opacity for modern depth and a controlled glow effect. Adjust hue, saturation, lightness and opacity with real-time preview, then copy clean CSS code (HEX, RGB, HSL) sRGB-compliant for your linear, radial gradients, colored shadows and modern filters.
Shadow matching background color
Shadow takes the element's hue with reduced opacity. This creates visual coherence and a natural luminosity effect.
Intense neon effect
Stack multiple shadows with increasing blur (2px, 10px, 20px, 40px) for realistic neon effect. Use vivid saturated colors.
Colored shadows for buttons and CTAs
Buttons with colored shadow naturally attract the eye. Shadow reinforces button color and creates a floating effect. Ideal for signup, purchase and main action buttons.
Shadow animations on hover
Animate shadow on hover for engaging visual feedback. Increase spread and opacity for "lift" effect, or create subtle pulsation with keyframes.
Multiple box-shadow for complex effects
Combine multiple box-shadows in one property for sophisticated effects: drop shadow + glow + reflection. Our generator lets you easily create and stack these shadows.
Compatibility and performance
Box-shadows are supported by all browsers. For performance, avoid animating shadows on many elements simultaneously. Prefer will-change to prepare GPU.
Colored shadows: adding depth
A colored shadow (for example blue under a blue button) creates a natural glow that guides the eye. Use 30-50% opacity and 20-40px blur for a professional, non-aggressive look.
