The all CSS shorthand property sets all of an element's properties (apart from unicode-bidi and direction) to their initial or inherited values, or to the values specified in another style sheet origin.

/* Global values */
all: initial;
all: inherit;
all: unset;

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

Initial valueThere is no practical initial value for it.
Applies toall elements
Inheritedno
MediaThere is no practical media for it.
Computed valueas the specified value applies to each property this is a shorthand for.
Animation typeas each of the properties of the shorthand (all properties but unicode-bidi and direction)
Canonical orderthe unique non-ambiguous order defined by the formal grammar

Syntax

The all property is specified as one of the CSS global keyword values. Note that none of these values affect the unicode-bidi and direction properties.

Values

initial
Specifies that all the element's properties should be changed to their initial values.
inherit
Specifies that all the element's properties should be changed to their inherited values.
unset
Specifies that all the element's properties should be changed to their inherited values if they inherit by default, or to their initial values if not.
revert
Specifies behavior that 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 values are calculated as if no author-level or user-level rules were specified for the element.
Author origin
Rolls back the cascade to the user level, so that the specified values are calculated as if no author-level rules were specified for the element. For purposes of revert, the Author origin includes the Override and Animation origins.

Formal syntax

initial | inherit | unset | revert

Examples

HTML

<blockquote id="quote">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</blockquote> Phasellus eget velit sagittis.

CSS

body {
  font-size: small;
  background-color: #F0F0F0;
  color: blue;
}

blockquote {
  background-color: skyblue;
  color: red;
}

Result

No all property

The <blockquote> uses the browser's default styling together with a specific background and text color. It also behaves as a block element: the text that follows it is beneath it.

all:unset

The <blockquote> doesn't use the browser default styling: it is an inline element now (initial value), its background-color is transparent (initial value), but its font-size is still small (inherited value) and its color is blue (inherited value).

all:initial

The <blockquote> doesn't use the browser default styling: it is an inline element now (initial value), its background-color is transparent (initial value), its font-size is normal (initial value) and its color is black (initial value).

all:inherit

The <blockquote> doesn't use the browser default styling: it is a block element now (inherited value from its containing <body> element), its background-color is #F0F0F0 (inherited value), its font-size is small (inherited value) and its color is blue (inherited value).
