<body>
<canvas id="straightline" width="200" height="200" style="border:7px dotted #000089;">
<!--we always use canvas id for script-->
<!--since we are going to draw square, we use attribute width and height with style/css-->
<!-- here the width and height defines canvas size-->
<!--since it has no border so-->
<!--we can use different color with the help of css-->
</canvas>
<script>
var ele = document.getElementById("straightline"); //this code finds the canvas Element using getElementbyID
var object = ele.getContext("2d"); //it creates an object for given canvas using getcontext. Then stores in variable
object.moveTo(0, 0); //it is the starting point of line.
object.lineTo(200, 200); //it is the ending part of line
object.stroke(); //it draws or connects both the co-ordinates
