What is @csstools/postcss-media-minmax?

@csstools/postcss-media-minmax is a PostCSS plugin that allows you to use the `<=` and `>=` operators in CSS media queries. This simplifies the syntax for writing media queries and makes them more readable.

What are @csstools/postcss-media-minmax's main functionalities?

Using `<=` in media queries

This feature allows you to use the `<=` operator in media queries, which is transformed into the equivalent `max-width` query.

/* Input CSS */
@media (width <= 600px) {
  .example {
    background: red;
  }
}

/* Output CSS */
@media (max-width: 600px) {
  .example {
    background: red;
  }
}

Using `>=` in media queries

This feature allows you to use the `>=` operator in media queries, which is transformed into the equivalent `min-width` query.

/* Input CSS */
@media (width >= 800px) {
  .example {
    background: blue;
  }
}

/* Output CSS */
@media (min-width: 800px) {
  .example {
    background: blue;
  }
}

Combining `<=` and `>=` in media queries

This feature allows you to combine `<=` and `>=` operators in a single media query, which is transformed into the equivalent `min-width` and `max-width` query.

/* Input CSS */
@media (400px <= width <= 800px) {
  .example {
    background: green;
  }
}

/* Output CSS */
@media (min-width: 400px) and (max-width: 800px) {
  .example {
    background: green;
  }
}
