## Pure Mode
|
||
|
|
|
||
|
|
In pure mode, all selectors must contain at least one local class or id
|
||
|
|
selector
|
||
|
|
|
||
|
|
To ignore this rule for a specific selector, add the a `/* cssmodules-pure-ignore */` comment in front
|
||
|
|
of the selector:
|
||
|
|
|
||
|
|
```css
|
||
|
|
/* cssmodules-pure-ignore */
|
||
|
|
:global(#modal-backdrop) {
|
||
|
|
...;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
or by adding a `/* cssmodules-pure-no-check */` comment at the top of a file to disable this check for the whole file:
|
||
|
|
|
||
|
|
```css
|
||
|
|
/* cssmodules-pure-no-check */
|
||
|
|
|
||
|
|
:global(#modal-backdrop) {
|
||
|
|
...;
|
||
|
|
}
|
||
|
|
|
||
|
|
:global(#my-id) {
|
||
|
|
...;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
