selector-combinator-space-before

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

  a > b + c ~ d e { 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 descendent combinator is not checked by this rule.

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

Options
