Usage

To use react-gradient-animation, wrap the GradientBackground component within a container that has a set width and height and a position: relative style.

import React from "react";
import { GradientBackground } from "react-gradient-animation";

function App() {
  return (
    <div style={{ position: "relative", width: "100%", height: "500px" }}>
      <GradientBackground
        count={20}
        size={{ min: 500, max: 700, pulse: 0.3 }}
        speed={{ x: { min: 0.5, max: 2 }, y: { min: 0.5, max: 2 } }}
        colors={{
          background: "#1e1e1e",
          particles: ["#ff007f", "#7f00ff", "#00ffff"],
        }}
        blending="overlay"
        opacity={{ center: 0.5, edge: 0 }}
        skew={-2}
        shapes={["c", "s", "t"]}
        style={{ opacity: 0.8 }}
      />
      {/* Other content */}
    </div>
  );
}

export default App;

Examples

Basic Usage

import React from "react";
import { GradientBackground } from "react-gradient-animation";

function BasicExample() {
  return (
    <div style={{ position: "relative", height: "400px" }}>
      <GradientBackground />
      {/* Your content here */}
    </div>
  );
}

export default BasicExample;

Custom Configuration

import React from "react";
import { GradientBackground } from "react-gradient-animation";

function CustomExample() {
  return (
    <div style={{ position: "relative", width: "100%", height: "600px" }}>
      <GradientBackground
        count={15}
        size={{ min: 800, max: 1000, pulse: 0.4 }}
        speed={{ x: { min: 1, max: 2 }, y: { min: 1, max: 2 } }}
        colors={{
          background: "#0d0d0d",
          particles: ["#ff6347", "#1e90ff", "#32cd32"],
        }}
        blending="screen"
        opacity={{ center: 0.6, edge: 0 }}
        skew={-3}
        shapes={["c", "t"]}
        style={{ opacity: 0.9 }}
      />
      {/* Your content here */}
    </div>
  );
}

export default CustomExample;

Usage Notes

• Container Requirements: The GradientBackground component should be placed within a container that has:
  • A set width and height.
  • position: relative style to ensure the canvas overlays correctly.
• Styling: You can pass custom styles via the style prop or use the className prop to apply CSS classes.
• Shapes: Mix and match different shapes by passing an array to the shapes prop. The particles will cycle through the provided shapes.
• Performance Considerations: Higher values for count and larger size ranges may impact performance on lower-end devices. Adjust the speed and pulse values to optimize animation smoothness.
