Sass::MediaQueryCombiner

Combines all matching media queries while compiling your Sass.

If you're using Rails 3.1+ or Sprockets, you should use sprockets-media_query_combiner.

For node pipelines try node-css-mqpacker.

For example:

h3 {
  color: orange
}
@media (max-width: 480px) {
  h1 {
    color: red
  }
}
@media (max-width: 980px) {
  h4 {
    color: black
  }
}
@media (max-width: 480px) {
  h2 {
    color: blue
  }
}

Would end up as (except the whitespace won't be so clean):

h3 {
  color: orange
}
@media (max-width: 480px) {
  h1 {
    color: red
  }
  h2 {
    color: blue
  }
}
@media (max-width: 980px) {
  h4 {
    color: black
  }
}

Note

This will change the order of your css, so be aware of that. All the @media queries will end up at the end of each css file in the order that they are first encountered. In other words, if you're relying on only using min-width or only using max-width in a specific order you'll want to be sure define your media queries in the right order up front before you use them randomly throughout your file.
