selector-max-specificity
Limit the specificity of selectors.
    .foo, #bar.baz span, #hoo { color: pink; }
/** ↑     ↑              ↑
 * Each of these selectors */Visit the Specificity Calculator for visual representation of selector specificity.
This rule ignores selectors with variable interpolation
(#{$var}, @{var}, $(var)).
This rule resolves nested selectors before counting the specificity of a selector. Each selector in a selector list is evaluated separately.
Options
string: Maximum specificity allowed.
Format is "id,class,type", as laid out in the W3C
selector spec.
For example, with "0,2,0":
The following patterns are considered violations:
#foo {}.foo .baz .bar {}.foo .baz {
  & .bar {}
}.foo {
  color: red;
  @nest .baz .bar & {
    color: blue;
  }
}The following patterns are not considered violations:
div {}.foo div {}.foo div {
  & div a {}
}.foo {
  & .baz {}
}.foo {
  color: red;
  @nest .baz & {
    color: blue;
  }
}Optional secondary options
ignoreSelectors: ["/regex/", /regex/, "string"]
Given:
[
  "0,2,0",
  {
    ignoreSelectors: [":global", ":local", "/my-/"]
  }
]
The following patterns are not considered violations:
:global(.foo) .bar {}:local(.foo.bar):local(.foo, :global(.bar).baz)The following patterns are considered violations:
:global(.foo) .bar.baz {}:local(.foo.bar.baz):local(.foo, :global(.bar), .foo.bar.baz)
