+# 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; } }
+```
+
+The following patterns are *not* considered warnings:
+
+```scss
+@media screen and (min-width: 100px){ b { color: red; } }
+```
+
+```scss
+@media screen and (min-width: 100px + 10px){ b { color: red; } }
+```
+
+```scss
+@media screen and (min-width: funcName(10px)){ b { color: red; } }
+```
