selector-combinator-space-before

Require a single space or disallow whitespace before the combinators of selectors.

  a > b + c ~ d e >>> f { color: pink; }
/** ↑   ↑   ↑  ↑  ↑
 * These are combinators */

The descendant combinator is not checked by this rule.

Also, + and - signs within :nth-*() arguments are not checked (e.g. a:nth-child(2n+1)).

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