Definition and Usage
The background-image
property sets one or more background images for an element.
By default, a background-image is placed at the top-left corner of an
element, and repeated both vertically and horizontally.
Tip: The background of an element is the total size of the element, including
padding and border (but not the margin).
Tip: Always set a background-color to be used if the image is unavailable.
