+# media-feature-range-notation
+
+Specify context or prefix notation for media feature ranges.
+
+<!-- prettier-ignore -->
+```css
+@media (width >= 600px) and (min-width: 600px) {}
+/**    ↑                    ↑
+ *     These media feature notations */
+```
+
+Media features of the range type can be written using prefixes or the more modern context notation.
+
+Because `min-` and `max-` both equate to range comparisons that include the value, they may be [limiting in certain situations](https://drafts.csswg.org/mediaqueries/#mq-min-max).
+
+## Options
+
+`string`: `"context"|"prefix"`
+
+### `"context"`
+
+Media feature ranges _must always_ use context notation.
+
+The following patterns are considered problems:
+
+<!-- prettier-ignore -->
+```css
+@media (min-width: 1px) {}
+```
+
+<!-- prettier-ignore -->
+```css
+@media (min-width: 1px) and (max-width: 2px) {}
+```
+
+The following patterns are _not_ considered problems:
+
+<!-- prettier-ignore -->
+```css
+@media (width >= 1px) {}
+```
+
+<!-- prettier-ignore -->
+```css
+@media (1px <= width >= 2px) {}
+```
+
+### `"prefix"`
+
+Media feature ranges _must always_ use prefix notation.

+The following patterns are considered problems:
+
+<!-- prettier-ignore -->
