The 'background' property is a shorthand property for setting the individual background properties at the same place in the style sheet.
The 'background' property first sets all the individual background properties to their initial values, then assigns explicit values given in the declaration.
<background-color> || <background-image> || <background-repeat> || <background-attachment> || <background-position>
p { background: url("chess.png") gray 50% repeat fixed }
body { background: red }
