unset
The unset
CSS keyword resets a property to its inherited value if the property naturally inherits from its parent, and to its initial value if not. In other words, it behaves like the inherit
keyword in the first case, when the property is an inherited property, and like the initial
keyword in the second case, when the property is a non-inherited property.
unset
can be applied to any CSS property, including the CSS shorthand all
.
