<canvas id="canvas1" width =”600” height= “500”> hello update the your browser</canvas>
We can have multiple canvases on one HTML page.
<!DOCTYPE html> <html> <header> </header> <body> <h3>hello demo</h3> <canvas id="canid" width="600" height="400">Update your browser chrome</canvas> <script> var tempcan=document.getElementById(canid); var tempcan2=tempcan.getContext("2d"); tempcan2.fillStyle='#0000ff'; tempcan2.fillRect(25,25,180,100); </script> </body> </html>
