* 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.
