List the styles commonly used to create and place a background image on a Web page.

What will be an ideal response?

To create a background image that is half the width and height of the containing element, centered vertically and horizontally, and not tiled, you could apply the following styles:
background-position: center center;
background-repeat: no-repeat;
background-size: 50% 50%;
In the box model discussed earlier, every element contains a content box, a padding box, and a border box. You can define the extent of a background image or color using the style
background-clip: box;
where box is content-box, padding-box, or border-box (the default).
