Write the code necessary to create a 300 pixel by 300 pixel <canvas>. Within it, paint a blue 100 pixel by 100 pixel square with

An easiest way will be to look on my codes.

<canvas id="c" width="300" height="300"></canvas> <script> var canvas = document.getElementById( "c" ); var drawing_context = canvas.getContext( "2d" ); drawing_context.fillStyle = "blue"; drawing_context.fillRect( 50, 50, 100, 100 ); </script>

Don't ask for code. Try to do yourself.
