The background property sets the following properties:

Syntax

bg-size

repeat-style

attachment

box
If one box value is present then it sets both background-origin and background-clip to that value. If two values are present, then the first sets background-origin and the second background-clip.
'background-color'
Sets the background-color property.

In addition, all CSS properties also accept the following CSS-wide keyword values as the sole component of their property value:

initial
Represents the value specified as the property's initial value.
inherit
Represents the computed value of the property on the element's parent.
unset
This value acts as either inherit or initial, depending on whether the property is inherited or not. In other words, it sets all properties to their parent value if they are inheritable or to their initial value if not inheritable.
