initial - CSS: Cascading Style Sheets 编辑

The initial CSS keyword applies the initial (or default) value of a property to an element. It can be applied to any CSS property. This includes the CSS shorthand all, with which initial can be used to restore all CSS properties to their initial state.

On inherited properties, the initial value may be unexpected. You should consider using the inherit, unset, or revert keywords instead.
