<!DOCTYPE html>
<html>
<head>
  <title>Full Screen Canvas</title>
  <style>
    body {
      margin: 0;
      overflow: hidden;
    }

    canvas {
      display: block;
    }
  </style>
</head>
<body>
  <canvas id="myCanvas"></canvas>

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

    canvas.width = window.innerWidth;
    canvas.height = window.innerHeight;

    // Your drawing code goes here
  </script>
</body>
</html>


In this code snippet, we first create a canvas element with the ID "myCanvas". We then use JavaScript to set the width and height of the canvas element equal to the width and height of the window using window.innerWidth and window.innerHeight.


You can then add your drawing code between the <script> tags to draw on the canvas. This will make the canvas full screen and responsive to the size of the window.
