There is one keyword that is shared by all properties in CSS2.1: inherit. inherit makes the value of a property the same as the value of its parent element. In most cases, you don't need to specify inheritance, since most properties inherit naturally; however, inherit can still be very useful.

For example, consider the following styles and markup:

#toolbar {background: blue; color: white;}

One | Two | Three

The div itself will have a blue background and a white foreground, but the links will be styled according to the browser's preference settings. They'll most likely end up as blue text on a blue background, with white vertical bars between them.

You could write a rule that explicitly sets the links in the "toolbar" to be white, but you can make things a little more robust by using inherit. You simply add the following rule to the style sheet:

#toolbar a {color: inherit;}

This will cause the links to use the inherited value of color in place of the user agent's default styles. Ordinarily, directly assigned styles override inherited styles, but inherit can reverse that behavior.
