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: 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.

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).
