all

all

The CSSall shorthand property resets all properties, apart from unicode-bidi and direction, to their initial or inherited value.

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
