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.

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(*) {}
