Media Queries Level 4: Media Query Range Contexts

Written by / Original link on Oct. 25, 2021


A media feature like width can take its value from a range. When used, we prefix these with min- or max- to express “minimum condition” or “maximum condition” constraints.

@media (min-width: 300px) and (max-width: 750px) {

In CSS Media Queries Level 4 these type of Media Features can now be written as a “range context”, which uses ordinary mathematical comparison operators.

@media (300px <= width <= 750px) {

The syntax might seem a little bit odd at first, but for me the trick is to read it as “the width sits in between the two values”

Also works with a single value:

/* Old Way */
@media (max-width: 750px) {
/* New Way */
@media (width <= 750px) {


At the time for writing, only Gecko/Firefox supports Range Contexts (ever since Firefox 63). There was some (minor) movement in the Blink/Chromium issue in September, but progress seems to have stalled. No word on WebKit/Safari.

The pen embedded below will indicate if your browser supports Media Query Range Contexts or not:



If you’re using PostCSS, you can use the postcss-media-minmax processor to already write Range Contexts:

npm install postcss-media-minmax
var fs = require('fs')
var postcss = require('postcss')
var minmax = require('postcss-media-minmax')

var css = fs.readFileSync('input.css', 'utf8')

var output = postcss()
console.log('\n====>Output CSS:\n', output)
