all

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

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

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

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

Values

initial

This keyword specifies that all property values set on the element all is set on — or inherited from the element's parent — should be changed to their initial values. unicode-bidi and direction values are not affected.

inherit

This keyword specifies that all property values set on the element all is set on should be changed to their inherited values, i.e. the values set on the element's parent. unicode-bidi and direction values are not affected.

unset

This keyword indicates that all property values set on the element all is set on should be changed to their inherited value if they are inheritable, or 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 | 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;
}

Results in:

No `all` property

The <blockquote> uses the browsers 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).
