#selector-combinator-space-after

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

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

Combinators are used to combine several different selectors into new and more specific ones. There are several types of combinators, including: child (>), adjacent sibling (+), general sibling (~), and descendant (which is represented by a blank space between two selectors).

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 on the command line can automatically fix all of the problems reported by this rule.
