Gan sekaran ini saya ingin bikin games nih tapi menggunakan HTML,, hehehehe
Coba Lihat gan langkah - langkahnya seperti di bawah ini
1. Pertama - tama kita buka aplikasi Macromedia Dremmever atau Notped
2. Copas Source Code Dibawah ini
Source Code :
<html lang="en">
<head>
<meta name="viewport" content="width=device-width,
user-scalable=no, initial-scale=1, maximum-scale=1, user-scalable=0" />
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="black-translucent" />
<style type="text/css">
body { margin: 0; padding: 0; background: #000;}
canvas { display: block; margin: 0 auto; background: #00FF00; }
</style>
</head>
<body>
<canvas></canvas>

window.oRequestAnimationFrame ||
window.msRequestAnimationFrame ||
function( callback ){
window.setTimeout(callback, 1000 / 60);
};
})();
