| 5 | [PostCSS Selector Not] transforms :not() W3C CSS level 4 pseudo classes to :not() CSS level 3 selectors following the [Selectors 4 Specification].
|

| 6 |
|
|---|
| 7 | ```pcss
|
|---|
| 8 | p:not(:first-child, .special) {
|
|---|
| 9 | color: red;
|
|---|
| 10 | }
|
|---|
| 11 |
|
|---|
| 12 | /* becomes */
|
|---|
| 13 |
|
|---|
| 14 | p:not(:first-child):not(.special) {
|
|---|
| 15 | color: red;
|
|---|
| 16 | }
|
|---|
| 17 | ```
|
|---|
| 18 |
|
|---|
| 19 | ⚠️ Only lists of simple selectors (`:not(.a, .b)`) will work as expected.
|
|---|
| 20 | Complex selectors (`:not(.a > .b, .c ~ .d)`) can not be downgraded.
