Solution

HTML5 provides addcolorstop() method to identify the colors and location in a gradient object. This is a method of HTML5 canvas element.

Syntax of addcolorstop()

gradient.addColorStop(stop,color);

Here, stop is a value between 0.0 and 1.0 that represents the position between start and end in a gradient and color is a color value to display at the stop position.

This is the following HTML5 code to draw a rectangle using canvas and fill color in gradient from red to pink from start to end.

<!DOCTYPE html>
<html>
<head>
	<title>addcolorstop() method</title>
</head>
<body>
<canvas id ="convasbx"
 width="300" height="150" style="border:1px solid #d3d3d3;">
Your browser doesn't currently support HTML5 Canvas.
</canvas> 
<script>
	var c = document.getElementById("convasbx");
	var context= c.getContext("2d");
	var gradient= context.createLinearGradient(10,10,150,0);
	gradient.addColorStop(0, "red");
	gradient.addColorStop(1, "pink");
	context.fillStyle = gradient;
	context.fillRect(30, 20, 180, 100);
</script>
</body>
</html>

Output of the above code

In the above code, getContext() method returns an object for working on canvas, the fillStyle is a property of canvas and used to fill color gradient in the drawing and the fillRect() method is used to draw a filled rectangle.
