            // get the canvas element using the DOM
            var canvas = document.getElementById('mycanvas');
            
            // Make sure we don't execute when canvas isn't supported
            if (canvas.getContext) {
            
               // use getContext to use the canvas for drawing
               var ctx = canvas.getContext('2d');
               
               ctx.fillStyle = '#00F';
               ctx.font = 'Italic 30px Sans-Serif';
