Mesh Gradient

Smooth flowing colors

Use Cases & Features

This animated mesh gradient is perfect for website backgrounds where you want to create a modern and dynamic impression.

  • Hero Sections: The first impression of a landing page to captivate visitors’ attention.
  • Login / Sign-up Screens: Turns often-boring authentication screens into attractive visual experiences.
  • Card Backgrounds: Backgrounds for credit card UIs or other premium elements.
  • Features:
    • Built entirely with CSS; lightweight without relying on Canvas or WebGL.
    • Beautiful and natural color blending achieved with mix-blend-mode: screen and filter: blur().
    • Performance optimized with the application of will-change: transform.

Design & UX Insights

  • Smooth Motion: By offsetting the animation duration of each circular element, it creates irregular, organic, and natural movement.
  • Color Harmony: Utilizes contrasting neon pink, vivid blue, cyan, and yellow, designed to produce deep and rich colors when blended together.
  • Glassmorphism Synergy: Applying a backdrop-filter (background blur) to the foreground content creates a modern design where the underlying gradient shines through.

Customization Guide

  • Changing Colors: You can modify the radial-gradient colors inside the .mesh-blob-* classes to match your brand’s color palette.
  • Adjusting Movement: Reducing the translate values in the @keyframes float* animations will result in calmer, more subtle movement.
  • Blur Intensity: By tweaking the filter: blur(60px) value in .mesh-bg, you can make the color blending either sharper or even smoother.
