<!-- prettier-ignore -->
```css
a::before {}
/** ↑
* This pseudo-element selector */
```

- CSS2 pseudo-elements i.e. those prefixed with a single colon
- selectors that use variable interpolation e.g. `::#{$variable} {}`
## Options
`array|string|regex`: `["array", "of", "unprefixed", "pseudo-elements" or "regex"]|"pseudo-element"|/regex/`
Given:
```
["before", "/^my-/i"]
```
The following patterns are considered violations:
<!-- prettier-ignore -->
```css
a::after {}
```
<!-- prettier-ignore -->
```css
a::not-my-pseudo-element {}
```

```
<!-- prettier-ignore -->
