CSS background properties are used to define the background effects of an element.
CSS properties used for background effects:
The background-color property specifies the background color of an element.

an RGB value - like "rgb(255,0,0)"
a color name - like "red"

The background-image property specifies an image to use as the background of an element.
By default, the image is repeated so it covers the entire element.

The position of the image is specified by the background-position property:
