function-calc-no-unspaced-operator

Disallow an unspaced operator within calc functions.

a { top: calc(1px + 2px); }
/**               ↑
 * The space around this operator */

Before the operator, there must be a single whitespace or a newline plus indentation. After the operator, there must be a single whitespace or a newline.

Note: The * and / operators do not require whitespace (but it is usually recommened for consistency).

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