To fill the whole canvas with a specific color using JavaScript, you can use the fillRect() method of the canvas context.
To do this, we write:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Fill Canvas with Color</title>
</head>
<body>
<canvas id="myCanvas" width="400" height="300"></canvas>
<script>
// Get reference to the canvas element
var canvas = document.getElementById('myCanvas');
var ctx = canvas.getContext('2d');
// Specify the color you want to fill the canvas with
var fillColor = '#ff0000'; // Red color, you can change this to any color
// Set the fill color
ctx.fillStyle = fillColor;
// Fill the entire canvas with the specified color
ctx.fillRect(0, 0, canvas.width, canvas.height);
</script>
</body>
</html>
In this example, we’re using the fillRect() method to draw a filled rectangle that covers the entire canvas.
We set the fill color using ctx.fillStyle, and then we use ctx.fillRect() to draw a rectangle starting at coordinates (0, 0) with a width equal to the canvas width and a height equal to the canvas height.
Adjust the fillColor variable to specify the color you want to fill the canvas with.
