CSS Neumorphism Generator

Build soft, extruded “neumorphic” UI elements without hand-tuning two opposing box-shadows. Pick a base color, choose a shape (flat, concave, convex, or pressed), drag the sliders for distance, intensity, blur, and light angle, then copy the generated CSS straight into your project.

Como usar

Pick a background color. The same color is used for the element and the surrounding canvas — that is what makes neumorphism work.
Choose a shape: Plano, Concave (subtle dip in), Convex (subtle pop out), or Recorte Interno (pressed in).
Ajuste Distância e Light Angle to set the shadow direction.
Tune Intensidade e Blur until the surface feels right.
Copy the CSS, or toggle Mostrar HTML + CSS for a paste-ready snippet.

Características

Pré-visualização em tempo real — every slider change updates the rendered element instantly.
Five built-in presets — Soft Light, Strong Light, Soft Dark, Strong Dark, and Pressed.
Auto-derived shadow colors — light and dark shadows are mathematically lightened/darkened from your base color so the effect always matches.
Concave and convex gradients — the tool generates a matching linear gradient for the element’s surface in those modes.
Inset (pressed) mode — for buttons that look “pushed in” on click.
Light angle control — rotate the virtual light source from 0° to 360°.
Copy-ready CSS — clean output with both the box-shadow declaration and the surface background.

 Perguntas frequentes

What is neumorphism?

Neumorphism (also called soft UI) is a visual style where elements appear to extrude from or sink into the background. It is achieved with two box-shadows of equal blur — one lighter shadow on the side facing the light and one darker shadow on the opposite side — both rendered against a background of the same color as the element itself.
Why does the element have to share the background color?

Neumorphism relies on the illusion that the shape is part of the same surface as the background. If the element uses a different color it stops looking like an extrusion and instead reads as a flat tile with two random shadows, which breaks the effect.
Are neumorphic interfaces accessible?

They have well-known accessibility trade-offs. Because all elements share the background color, contrast against text and other UI is often very low, which can fail WCAG contrast requirements and confuse screen-magnifier users. Use neumorphism for decorative surfaces and keep critical interactive elements high-contrast.
How is the light angle related to the shadow offsets?

The two shadow offsets are derived from the light angle using basic trigonometry: offsetX = cos(angle) × distance, offsetY = sin(angle) × distance. The opposite shadow is placed at the negated offsets so the light and dark sides always sit on opposite edges, matching where a real light source would cast them.
