Initial value	There is no practical initial value for it.
Applies to	all elements
Inherited	no
Media	There is no practical media for it.
Computed value	as the specified value applies to each property this is a shorthand for.
Animation type	as each of the properties of the shorthand (all properties but unicode-bidi and direction)
Canonical order	the unique non-ambiguous order defined by the formal grammar

Syntax

all: initial;
all: inherit;
all: unset;

/* CSS Cascading and Inheritance Level 4 */
all: revert;

Values

initial

This keyword indicates to change all the properties applying to the element or the element's parent to their initial value. unicode-bidi and direction values are not affected.

inherit

This keyword indicates to change all the properties applying to the element or the element's parent to their parent value. unicode-bidi and direction values are not affected.

unset

This keyword indicates to change all the properties applying to the element or the element's parent to their parent value if they are inheritable or to their initial value if not. unicode-bidi and direction values are not affected.

revert

If the cascaded value of a property is the revert keyword, the behavior depends on the origin to which the declaration belongs:

user-agent origin

Equivalent to unset.

user origin

Rolls back the cascade to the user-agent level, so that the specified value is calculated as if no author-level or user-level rules were specified for this property.

author origin

Rolls back the cascade to the user level, so that the specified value is calculated as if no author-level rules were specified for this property. For the purpose of revert, this origin includes the Override and Animation origins.

Formal syntax

initial | inherit | unset
