all

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

Syntax

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

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

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 stylesheet 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).
