How to properly set up a gradient for canvas?

To set up a gradient for a canvas in HTML5, you can use the CanvasRenderingContext2D interface and its createLinearGradient() or createRadialGradient() methods. Here is a step-by-step guide on how to properly set up a gradient for a canvas:

1. Create a canvas element in your HTML file:

1

<canvas id="myCanvas" width="200" height="200"></canvas>

1. Get the canvas element and its 2d rendering context in your JavaScript file:

1
2

const canvas = document.getElementById('myCanvas');
const ctx = canvas.getContext('2d');

1. Create a linear gradient:

1
2
3

const gradient = ctx.createLinearGradient(0, 0, canvas.width, canvas.height);
gradient.addColorStop(0, 'red');
gradient.addColorStop(1, 'blue');

1. Fill the canvas with the gradient:

1
2

ctx.fillStyle = gradient;
ctx.fillRect(0, 0, canvas.width, canvas.height);

This will create a linear gradient that goes from red to blue diagonally across the canvas. You can customize the gradient by adding more color stops and changing the direction of the gradient.

Alternatively, you can create a radial gradient by using the createRadialGradient() method and specifying the coordinates and radius of the gradient.
