"Let us prepare our minds as if we'd come to the very end of life. Let us postpone nothing. Let us balance life's books each day ... The one who puts the finishing touches on their life each day is never short of time."
Seneca

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.
