Less:

  @import "library/mq";
  // or
  @import "library/mq-prefixed";

If you use Bower, the path would be:

  bower_components/less-mq/..

How to use

The build mixin name:

@(prefix)-(min|max)-(screen)-(height)

• @ - Sign of the variable in the preprocessor.
• (prefix) - The prefix [mq-] mixins. Namespace of your mixins and mixins of the library. (With mq-prefixed and without mq).
• (min|max) - For example, min-width or max-width.
• (screen) - Only for set min-width and max-width.
• (height) - Relevant only for min-height or max-height.

Full list mixins

// Width Screen
.min(@min, @ruleset);
.max(@max, @ruleset);
.screen(@min, @max, @ruleset);

//Hight Screen
.min-height(@min, @ruleset);
.max-height(@max, @ruleset);
.screen-height(@min, @max, @ruleset);

// Orientation
.landscape(@ruleset);
.portrait(@ruleset);

// HiDPI
.hdpi(@ratio, @ruleset);
.ratio(@ratio, @ruleset);

// Print
.print(@ruleset);

Example:

@import "library/mq";

// min-width
.area {
  .min(768px, {
    width: 750px;
  });
}

// min-width and max-width
.area-article {
  .screen(768px, 1200px, {
    background-color: red;
  });
}

// max-height
.box {
  .max-height(768px, {
    background-color: blue;
  });
}

Additional mixins

// Screen orientation (`.landscape` or `.portrait`)
.promo {
  .landscape({
    background-size: 80% auto;
  });
}

// The ratio of the number of dots per inch (default: 1.5)
.brand {
  .hdpi(1.5, {
    background: url('images/brand@2x.png') no-repeat top left / 200px 200px;
  });
  
  // or
  .hdpi({
    background: url('images/brand@2x.png') no-repeat top left / 200px 200px;
  });
}

// The ratio of the number of dots per inch
.ad {
  .print({
    display: none;
  });
}

Autoprefixer

If you are using resolution media queries (.hdpi() and alias), you need Autoprefixer for better browser support.

Without Autoprefixer:

@media
(min-resolution: 144dpi),
(min-resolution: 1.5ddpx) {
  /* You styles */
}

After Autoprefixer (safari >= 7, opera >= 12):

@media
(-webkit-min-device-pixel-ratio: 1.5),
(-o-min-device-pixel-ratio: 3/2),
(min-resolution: 144dpi),
(min-resolution: 1.5ddpx) {
  /* You styles */
}

Emmet snippet

Go to Preferens → Package Settings → Emmet → Settings – User, and add this lines:

{
	"snippets": {
		"less": {
			"abbreviations": {
				// Width Screen
				"mqmin": ".min(${1}, {\n${0}\n});",
				"mqmax": ".max(${1}, {\n${0}\n});",
				"mqscr": ".screen(${1}, ${2}, {\n${0}\n});",
				// Hight Screen
				"mqminh": ".min-height(${1}, {\n${0}\n});",
				"mqmaxh": ".max-height(${1}, {\n${0}\n});",
				"mqscrh": ".screen-height(${1}, ${2}, {\n${0}\n});",
				// Orientation
				"mqland": ".landscape({\n${0}\n});",
				"mqport": ".portrait({\n${0}\n});",
				// HiDPI
				"mqhdpi": ".hdpi(${1:1.5}, {\n${0}\n});",
				// Print
				"mqprint": ".print({\n${0}\n});"
			}
		}
	}
}
