# media-feature-name-no-unknown
|
||
|
|
|
||
|
|
Disallow unknown media feature names.
|
||
|
|
|
||
|
|
```css
|
||
|
|
@media (min-width: 700px) {}
|
||
|
|
/** ↑
|
||
|
|
* This media feature name */
|
||
|
|
```
|
||
|
|
|
||
|
|
This rule considers media feature names defined in the CSS Specifications, up to and including Editor's Drafts, to be known.
|
||
|
|
|
||
|
|
This rule ignores:
|
||
|
|
|
||
|
|
- media feature names within a range context
|
||
|
|
- vendor-prefixed media feature names
|
||
|
|
|
||
|
|
