all

The all shorthand CSS property resets all of an element's properties except unicode-bidi, direction, and CSS Custom Properties. It can set properties to their initial or inherited values, or to the values specified in another stylesheet origin.

Syntax

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

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 definition

Initial valueThere is no practical initial value for it.
Applies toall elements
Inheritedno
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)

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;   margin: 0;   padding: 0; }  blockquote {   background-color: skyblue;   color: red; } 

Result

No all property

The <blockquote> uses the browser's default styling which gives it a margin, 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).
