Answer 1

you had used wrong syntax and
here width and height are additional.. though if you want the background to be stretched to full width and height use the following
body {
width:100%;
height:500px;
background:-webkit-linear-gradient(to left top, red, yellow);
background:-moz-linear-gradient(to left top, red, yellow);
background:linear-gradient(to left top, red, yellow);
}
