This simple mixin does almost everything, that it'sinspirer can. Quote:

There are two major differences between this library and breakpoint-sass. First, it doesn't (and, in my humble opinion, shouldn't) take care of vendor prefixes. Second, there is no way to get context as describedhere.

Usage

First, include the main _breakpoint.less file like this:

@import "lib/_breakpoint";

Second, use it!

Single value

.test1 {      .breakpoint(450px, {          color: #fff;      });  }

@media only screen and (min-width: 450px) {      .test1 {          color: #fff;      }  }

Two values

.test2 {      .breakpoint("450px 500px", {          color: #fff;      });  }

@media only screen and (min-width: 450px) and (min-height: 500px) {      .test2 {          color: #fff;      }  }

Property and value pair

.test3 {      .breakpoint("max-width 1000px", {          color: #fff;      });  }

@media only screen and (max-width: 1000px) {      .test3 {          color: #fff;      }  }

Several media rules

.test4 {      .breakpoint("(min-height 1000px) (orientation portrait)", {          color: #fff;      });  }

@media only screen and (min-height: 1000px) and (orientation: portrait) {      .test4 {          color: #fff;      }  }

Type keywords

.test6 {      .breakpoint(300px, "not print", {          color: #fff;      });  }  .test7 {      .breakpoint(300px, "all", {          color: #fff;      });  }

@media not print and (min-width: 300px) {      .test6 {          color: #fff;      }  }  @media only all and (min-width: 300px) {      .test7 {          color: #fff;      }  }

You can see other examples in thetest file.

Vendor prefixes

Breakpoint-less doesn't worry about cross-browser compatibility. Neither should you. Who should, you might ask?Autoprefixer.

.test9 {      .breakpoint("min-resolution 3dppx", {          color: #fff;      });  }

/* Without autoprefixer */  @media only screen and (min-resolution: 3dppx) {      .test9 {          color: #fff;      }  }    /* With autoprefixer */  @media only screen and (-webkit-min-device-pixel-ratio: 3), only screen and (min-resolution: 3dppx) {      .test9 {          color: #fff;      }  }

Media queries concatenation

LESS (just as SASS) has absolutely no internal way to combine media queries. Sorry, just no. But with the power of another PostCSS library -CSS MQPacker - mission becomes possible:

.test10 {      .breakpoint(300px, {          color: #fff;      });  }  .test11 {      .breakpoint(300px, {          color: #fff;      });  }

@media only screen and (min-width: 300px) {      .test10 {          color: #fff      }      .test11 {          color: #fff      }  }
