inherit - CSS: Cascading Style Sheets 编辑
The 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
property.
Inheritance is always from the parent element in the document tree, even when the parent element is not the containing block.
Examples
Exclude selected elements from a rule
/* 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.
