postcss-media-minmax enhances your CSS workflow by providing convenient shorthand syntax for media queries dealing with minimum and maximum values. It allows you to use intuitive, readable syntax like (width < 768px) instead of the more verbose (max-width: 767.98px). This PostCSS plugin simplifies responsive design by reducing code clutter and improving maintainability. By translating the short-hand syntax to standard CSS, postcss-media-minmax ensures broad browser compatibility.
