To draw a line in HTML, use the canvas element. With canvas, use the lineTo() method to draw a line. The lineTo() method includes x and y parameter values, which positions the line.
Example
You can try to run the following code to draw a line with lineTo() in HTML5 −
<!DOCTYPE html>
<html>
<head>
<title>HTML Canvas</title>
</head>
<body>
<canvas id="newCanvas" width="300" height="150" style="border:1px solid #000000;"></canvas>
<script>
var c = document.getElementById("newCanvas");
var ctxt = c.getContext("2d");
ctxt.beginPath();
ctxt.moveTo(70, 50);
ctxt.lineTo(50, 120);
ctxt.stroke();
</script>
</body>
</html>
