# selector-nested-pattern Specify a pattern for the selectors of rules nested within rules. ```css a { color: orange; &:hover { color: pink; } } ↑ /** ↑ * These nested selectors */ ``` Non-standard selectors (e.g. selectors with Sass or Less interpolation) and selectors of rules nested within at-rules are ignored. ## Options `regex|string` A string will be translated into a RegExp — `new RegExp(yourString)` — so *be sure to escape properly*. The selector value will be checked in its entirety. If you'd like to allow for combinators and commas, you must incorporate them into your pattern. Given the string: ```js "^&:(?:hover|focus)$" ``` The following patterns are considered warnings: ```css a { .bar {} } ``` ```css a { .bar:hover {} } ``` ```css a { &:hover, &:focus {} } ``` The following patterns are *not* considered warnings: ```css a { &:hover {} } ``` ```css a { &:focus {} } ``` ```css a { &:hover {} &:focus {} } ```
