selector-max-type

Limit the number of type selectors in a selector.

    a {}
/** ↑
 * This type of selector */

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

The :not() pseudo-class 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 type selectors allowed.

For example, with 2:

The following patterns are considered violations:

div a span {}

div a {
  & span {}
}

div a {
  & > a {}
}

The following patterns are not considered violations:

div {}

div a {}

.foo div a {}

div.foo a {}

/* each selector in a selector list is evaluated separately */
div,
a span {}

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

Optional secondary options

ignore: ["child", "compounded", "descendant", "next-sibling"]

"child"

Discount child type selectors.

For example, with 2:

The following patterns are not considered violations:

div span > a {}

#bar div span > a {}

"compounded"

Discount compounded type selectors -- i.e. type selectors chained with other selectors.

For example, with 2:

The following patterns are not considered violations:

div span a.foo {}

div span a#bar {}

"descendant"

Discount descendant type selectors.

For example, with 2:

The following patterns are not considered violations:

.foo div span a {}

#bar div span a {}

"next-sibling"

Discount next-sibling type selectors.

For example, with 2:

The following patterns are not considered violations:

div a + span {}

#bar + div + span + a + span {}

ignoreTypes: ["/regex/", /regex/, "string"]

Given:

["/^my-/", "custom"]

For example, with 2.

The following patterns are not considered violations:

div a custom {}

div a my-type {}

div a my-other-type {}
