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
anddirection
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
anddirection
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
anddirection
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.

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).
