function-name-case

Specify lowercase or uppercase for function names.

a { width: calc(5% - 10em); }
/**        ↑
 * This function */

Camel case function names, e.g. translateX, are accounted for when the lower option is used.

The fix option can automatically fix all of the problems reported by this rule.
