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

        has 1rem of vertical margin set by the user-agent. The parent of the
        paragraph is a &lt;div&gt; with a dashed blue border.

Constituent properties

This property is a shorthand for all CSS properties except for {{cssxref("unicode-bidi")}}, {{cssxref("direction")}}, and custom properties.

Syntax

css
/* Global values */
all: initial;
all: inherit;
all: unset;
all: revert;
all: revert-layer;

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

Values

  • {{cssxref("initial")}}
    • : Specifies that all the element's properties should be changed to their initial values.
  • {{cssxref("inherit")}}
    • : Specifies that all the element's properties should be changed to their inherited values.
  • {{cssxref("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.
  • {{cssxref("revert")}}
    • : Specifies behavior that depends on the stylesheet origin to which the declaration belongs:
      • If the rule belongs to the author origin, the revert value 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.
      • If the rule belongs to the user origin, the revert value 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.
      • If the rule belongs to the user-agent origin, the revert value acts like unset.
  • {{cssxref("revert-layer")}}
    • : Specifies that all the element's properties should roll back the cascade to a previous cascade layer, if one exists. If no other cascade layer exists, the element's properties will roll back to the matching rule, if one exists, in the current layer or to a previous style origin.

Examples

In this example, the CSS file contains styling for the {{HTMLElement("blockquote")}} element in addition to some styling for the parent <body> element. Various outputs in the Results subsection demonstrate how the styling of the <blockquote> element is affected when different values are applied to the all property inside the blockquote rule.

HTML

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

CSS

css
body {
  font-size: small;
  background-color: #f0f0f0;
  color: blue;
  margin: 0;
  padding: 0;
}

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

Results

A. No all property

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;
}

{{EmbedLiveSample("a._no_all_property", "200", "125")}}

This is the scenario in which no all property is set inside the blockquote rule. The {{HTMLElement("blockquote")}} element uses the browser's default styling which gives it a margin, together with a specific background and text color as specified in the stylesheet. It also behaves as a block element: the text that follows it is beneath it.

B. all: initial

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;
  all: initial;
}

{{EmbedLiveSample("b._all_initial", "200", "125")}}

With the all property set to initial in the blockquote rule, the {{HTMLElement("blockquote")}} element doesn't use the browser default styling anymore: it is an inline element now (initial value), its background-color is transparent (initial value), its font-size is medium, and its color is black (initial value).

C. all: inherit

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;
  all: inherit;
}

{{EmbedLiveSample("c._all_inherit", "200", "125")}}

In this case, the {{HTMLElement("blockquote")}} element doesn't use the browser default styling. Instead, it inherits style values from its parent {{HTMLElement("body")}} element: it is a block element now (inherited value), its {{cssxref("background-color")}} is #F0F0F0 (inherited value), its {{cssxref("font-size")}} is small (inherited value), and its {{cssxref("color")}} is blue (inherited value).

D. all: unset

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;
  all: unset;
}

{{EmbedLiveSample("d._all_unset", "200", "125")}}

When the unset value is applied to the all property in the blockquote rule, the {{HTMLElement("blockquote")}} element doesn't use the browser default styling. Because background-color is a non-inherited property and font-size and color are inherited properties, the <blockquote> element is an inline element now (initial value), its {{cssxref("background-color")}} is transparent (initial value), but its {{cssxref("font-size")}} is still small (inherited value), and its {{cssxref("color")}} is blue (inherited value).

E. all: revert

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;
  all: revert;
}

{{EmbedLiveSample("e._all_revert", "200", "125")}}

When the all property is set to revert in the blockquote rule, the blockquote rule is considered to be non-existent and the styling property values are inherited from the ones applied to the parent element <body>. So the <blockquote> element gets styled as a block element, with {{cssxref("background-color")}} #F0F0F0, {{cssxref("font-size")}} small, and {{cssxref("color")}} blue - all values inherited from the body rule.

F. all: revert-layer

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;
  all: revert-layer;
}

{{EmbedLiveSample("f._all_revert-layer", "200", "125")}}

There are no cascade layers defined in the CSS file, so the <blockquote> element inherits its style from the matching body rule. The <blockquote> element here is styled as a block element, with {{cssxref("background-color")}} #F0F0F0, {{cssxref("font-size")}} small, and {{cssxref("color")}} blue - all values inherited from the body rule. This scenario is an example of the case when all set to revert-layer behaves the same as when all is set to revert.
