Neumorphism (also called Soft UI) is a design trend that uses dual-layered box shadows—one light and one dark—to create elements that appear to extrude from or sink into the background. It mimics physical objects on a soft, matte surface, giving interfaces a tactile, modern feel. Unlike flat design, neumorphism emphasizes depth through subtle highlight and shadow combinations.

Simply adjust the background color, card color, shadow intensity, blur radius, distance, and border radius using the sliders. Choose between Raised (element pops out), Inset (element sinks in), or Flat (no shadow). Pick a light direction to control where the highlight falls. The preview updates in real time.

Neumorphism uses standard CSS box-shadow and border-radius properties, which are supported by all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. For the inset shadow variant, support is equally universal. No vendor prefixes are needed. The generated CSS works on both desktop and mobile browsers with 99%+ global coverage.

Yes, but with care. Neumorphism works best for card components, buttons, form inputs, and dashboard widgets. However, ensure sufficient color contrast for accessibility—the subtle shadows can make it harder for visually impaired users to distinguish interactive elements. We recommend pairing neumorphic styling with clear typography, adequate spacing, and distinct hover/active states for interactive elements.

The key is to use low-saturation, mid-tone colors for both the background and the card. Pastel grays, soft beiges, muted blues, and light lavenders work exceptionally well. The background and card colors are often identical or very close—this makes the shadows blend naturally. Avoid pure white or pure black backgrounds, as they reduce the visible shadow contrast. Use our preset color schemes as a starting point.

Raised (convex) elements appear to push outward from the surface—the light shadow sits on the light-source side and the dark shadow on the opposite side. This is ideal for cards, buttons, and elevated containers. Inset (concave) elements appear pressed into the surface—the dark shadow sits on the light-source side and the light shadow on the opposite side, using the inset keyword. Inset is perfect for input fields, pressed buttons, and recessed areas.

Light direction determines where the highlight and shadow fall on the element. The traditional neumorphic look uses top-left lighting (light from upper-left, shadow to lower-right), which mimics natural overhead lighting. Changing the direction to top-right, bottom-left, or bottom-right shifts the highlight accordingly. Consistent light direction across all elements creates a cohesive, realistic look in your interface.
