inherit
CSS keyword causes the element for which it is specified to take the
computed value
of the property from its parent element.
It can be applied to any CSS property, including the CSS shorthand
all
.
For
inherited properties
, this reinforces the default behavior, and is only needed to override another rule. For
non-inherited properties
, this specifies a behavior that typically makes relatively little sense and you may consider using
initial
instead, or
unset
on the
all
特性。
Inheritance is always from the parent element in the document tree, even when the parent element is not the containing block.
/* Make second-level headers green */
h2 { color: green; }
/* ...but leave those in the sidebar alone so they use their parent's color */
#sidebar h2 { color: inherit; }
In this example the
h2
elements inside the sidebar might be different colors. For example, if one of them were the child of a div matched by the rule ...
div#current { color: blue; }
... it would be blue.
