Answer 1

Each time you click within the document you start another interval timer. Your HTML button onclick string isn't valid. It should call a function or have some valid statement.

Answer 2

Your CSS is /* Created by ravindra patel */

#container {
width:100%;
height: 200px;
background:#991100";
position: relative;
}
#box {
width: 50px;
height: 50px;
background: #556688;
position: absolute;
}
But, It sould be this
/* Created by ravindra patel */

#container {
width:100%;
height: 200px;
background:#991100;
position: relative;
}
#box {
width: 50px;
height: 50px;
background: #556688;
position: absolute;
}
