Detailed Description

Framework class for strings that involve multiple values.

Certain CSS properties such as border-width and margin allow multiple lengths to be specified. This class can take a vanilla border-width definition and multiply it, usually into a max of four.

Note

Even though the CSS specification isn't clear about it, inherit can only be used alone: it will never manifest as part of a multi shorthand declaration. Thus, this class does not allow inherit.
