# media-feature-value-dollar-variable
|
|
|
|
Require a media feature value be a `$`-variable or disallow `$`-variables in media feature values.
|
|
|
|
```scss
|
|
@media (max-width: $var) { a { color: red; } }
|
|
// ↑
|
|
// Require or disallow this
|
|
}
|
|
```
|
|
|
|
## Options
|
|
|
|
`string`: `"always"|"never"`
|
|
|
|
### `"always"`
|
|
|
|
A media feature value *must consist* of just a single `$`-variable (possibly with inteprolation).
|
|
|
|
The following patterns are considered warnings:
|
|
|
|
```scss
|
|
@media (max-width: 300px) { b { color: red; } }
|
|
```
|
|
|
|
```scss
|
|
@media (max-width: $var + 10px) { b { color: red; } }
|
|
```
|
|
|
|
```scss
|
|
@media screen and (max-width: $var), or (min-width: 100px){ b { color: red; } }
|
|
```
|
|
|
|
```scss
|
|
@media screen and (max-width: #{$val} + 10px) { a { display: none; } }
|
|
```
|
|
|
|
```scss
|
|
@media screen and (max-width: #{$val + $x} ) { a { display: none; } }
|
|
```
|
|
|
|
```scss
|
|
@media screen and (min-width: funcName($p)){ b { color: red; } }
|
|
```
|
|
|
|
The following patterns are *not* considered warnings:
|
|
|
|
```scss
|
|
@media ( max-width: $var ) {b { color: red; }}
|
|
```
|
|
|
|
```scss
|
|
@media ( max-width: #{$var}) {b { color: red; }}
|
|
```
|
|
|
|
### `"never"`
|
|
|
|
There *must never* be a `$`-variable in a media feature value. Even as a parameter to a function call.
|
|
|
|
The following patterns are considered warnings:
|
|
|
|
```scss
|
|
@media screen and (min-width: $var){ b { color: red; } }
|
|
```
|
|
|
|
```scss
|
|
@media screen and (min-width: 100px + $var){ b { color: red; } }
|
|
```
|
|
|
|
```scss
|
|
@media screen and (min-width: funcName($var)){ b { color: red; } }
|
|
```
