| 8 | * definition and multiply it, usually into a max of four.\r | |

| 10 | * @note Even though the CSS specification isn't clear about it, inherit\r | |
| 11 | * can only be used alone: it will never manifest as part of a multi\r | |
| 12 | * shorthand declaration. Thus, this class does not allow inherit.\r | |
