selector-max-universal

Limit the number of universal selectors in a selector.

    * {}
/** ↑
 * This universal selector */

This rule resolves nested selectors before counting the number of universal selectors. Each selector in a selector list is evaluated separately.

The logical combinations pseudo-class (e.g. :not, :has) is also evaluated separately. The rule processes the argument as if it were an independent selector, and the result does not count toward the total for the entire selector.

The message secondary option can accept the arguments of this rule.

Options

int: Maximum universal selectors allowed.

For example, with 2:

The following patterns are considered problems:

* * * {}

* * {
  & * {}
}

* * {
  & > * {}
}

The following patterns are not considered problems:

* {}

* * {}

.foo * {}

*.foo * {}

/* each selector in a selector list is evaluated separately */
*.foo,
*.bar * {}

/* `*` is inside `:not()`, so it is evaluated separately */
* > * .foo:not(*) {}

Optional secondary options

ignoreAfterCombinators: ["array", "of", "combinators"]

Ignore universal selectors that come after one of the specified combinators.

Given:

[">", "+"]

For example, with 2.

The following pattern is not considered a problem:

* * > * {}
