Interfaces are constantly evolving, but two trends have become firmly established: glassmorphism (the frosted glass effect) and neumorphism (soft, realistic shadows). Yet manually adjusting these effects can take time. Why not tune everything with visual sliders? That's exactly what our Visual Effects Generator does. It combines several CSS trends into one tool, complete with a contrast checker and a color‑blindness simulator, to create elegant and accessible components. Here's how it works.
One tool, six creative modes
Rather than juggling multiple windows and tools, the generator consolidates everything in a single interface. Each mode instantly updates the live preview – a real HTML card that you can customize (card, button, input, navbar, modal).
1. Glassmorphism: the frosted effect in a few clicks
The Glassmorphism mode reproduces the famous blurred background popularized by Windows 11 and macOS. You adjust:
- Blur (backdrop-filter blur), from 0 to 30 px.
- Background opacity, to control the transparency.
- Background color (pure white, tinted).
- Border radius, drop shadow (intensity, vertical offset, opacity).
- A semi‑transparent border that enhances the glass feel.
The generated CSS includes the -webkit-backdrop-filter prefix for Safari, so the effect works everywhere.
2. Neumorphism: Soft UI mastered
Neumorphism (or Soft UI) gives a soft, realistic look to interfaces. It relies on two shadows: one light and one dark, creating depth. The generator allows you to:
- Choose the background color of the element.
- Set the distance and intensity of the shadows.
- Switch between a convex (raised) and a pressed (inset) effect.
- Adjust the corner radius.
The shadows are automatically calculated by darkening and lightening the base color, ensuring visual harmony.
3. Hybrid Mode: Glass + Neumorph
Why choose between the two? The Hybrid mode overlays a subtle blur and transparency with neumorphic shadows. You get a frosted background that appears to float above the surface. Three main sliders: glass blur, glass opacity, and neumorphic shadow distance. The result: modern cards that feel lightweight yet tangible.
4. Text Effects: shadow, glow, outline
Sometimes it's not the container that needs an effect, but the text itself. The Text Effects mode offers three styles:
- Shadow: a colored drop shadow behind the letters.
- Glow: a luminous halo, perfect for impactful headings.
- Outline: a stroke around the text (via
-webkit-text-stroke), for a hollow or two‑tone effect.
Each option is fully customizable: text color, shadow/glow/outline color, thickness, and radius.
5. Keyframe Animations + Easing Editor
CSS animations bring an interface to life. With the Keyframes mode, you choose an animation type (fade, slide, scale, rotate, pulse) and then adjust:
- Duration (from 0.1 s to 3 s).
- Easing (ease, ease‑in, ease‑out, linear, or custom).
- Delay, iteration count (once, twice, three times, infinite), and direction (normal, alternate, reverse).
The icing on the cake: when you choose custom easing, a visual Bézier curve editor appears. Drag the two handles to sculpt the curve, and the tool generates the exact cubic-bezier() value. You can see in real time how the animation will speed up or slow down.
The full @keyframes code is exported along with the corresponding CSS class, ready to be integrated.
6. Preset Gallery
For inspiration or a quick start, a Gallery provides ten ready‑to‑use presets: frosted card, neumorphic button, glowing text, glass navbar, hybrid card, pressed button, outlined text, animated skeleton loader, glass modal, etc. Click on one, and the tool loads the corresponding settings, which you can then modify to your liking.
Built‑in accessibility: contrast and color blindness
A beautiful interface must remain readable for everyone. Two features make this generator unique:
- WCAG Contrast Checker: below the preview, pick a text color and a background color. The tool instantly calculates the contrast ratio and indicates whether AA or AAA levels are met (for normal and large text). It's an essential accessibility reflex when playing with transparency.
- Color‑blindness Simulator: activate a protanopia, deuteranopia, or tritanopia filter on the preview. The simulator uses LMS color matrices (Brettel‑Viénot model). You can verify that your effects remain distinguishable for all users, regardless of their color perception.
Multi‑format exports and sharing
Like all DevToolbox tools, the Visual Effects Generator offers several export formats:
- Pure CSS: the class with all properties (background, backdrop-filter, box-shadow, border-radius, etc.).
- Tailwind CSS: the class with bracket syntax, for example
backdrop-blur-[12px] bg-white/[.18]. - React JSX: a complete functional component with customizable props and inline styles.
- URL sharing: encode your entire configuration in a link. Send it to a colleague, and they'll get the same preview without having to configure anything.
Integration with the DevToolbox suite
The Visual Effects Generator works alongside other platform tools:
- The Background Generator helps you create the perfect background (gradients, mesh, patterns) on which to apply your effects.
- The CSS Shape Generator creates masks (clip‑path) and blobs that can be styled with glass or neumorph effects.
- Need to decode a JWT token? The JWT Decoder does it securely, client‑side.
- Format and validate JSON data with the JSON Formatter.
- Generate strong passwords and hash them with the Password & Hash Generator.
By combining these tools, you can prototype a complete interface – background, shape, and style – without leaving your browser and without writing a single line of code manually.
A few best practices
To get the most out of the generator:
- Test contrasts before deploying a glass effect; white text on a background that is too transparent can become invisible.
- Consider older browsers:
backdrop-filteris not supported by IE. Provide a more opaque background color as a fallback. - Don't overuse animations: a pulse effect on a main button can guide the user, but an entire pulsing page becomes tiring.
- Use hybrid mode sparingly: it produces a very rich result, well suited for premium cards or dashboards, but can visually clutter a minimalist interface.
