@media

The @media queries work just as they do within regular CSS, but with Stylus's block notation:

 @media print
   #header
   #footer
     display none

Yielding:

  @media print {
    #header,
    #footer {
      display: none;
    }
  }

Media Query Bubbling

Media queries can be nested, too, and they will be expanded to wrap the context in which they are used. For example:

.widget
  padding 10px
  
  @media screen and (min-width: 600px)
    padding 20px

Yielding:

.widget {
  padding: 10px;
}

@media screen and (min-width: 600px) {
  .widget {
    padding: 20px;
  }
}

Nested media queries

You can nest @medias one into another and they would combine into one:

@media (max-width: 500px)
  .foo
    color: #000

  @media (min-width: 100px), (min-height: 200px)
    .foo
      color: #100

Would yield to

@media (max-width: 500px) {
  .foo {
    color: #000;
  }
}
@media (max-width: 500px) and (min-width: 100px), (max-width: 500px) and (min-height: 200px) {
  .foo {
    color: #100;
  }
}

Interpolations and variables

You can use both interpolations and variables inside media queries, so it is possible to do things like this:

foo = 'width'
bar = 30em
@media (max-{foo}: bar)
  body
    color #fff

This would yield

@media (max-width: 30em) {
  body {
    color: #fff;
  }
}

It is also possible to use expressions inside MQ:

.foo
  for i in 1..4
    @media (min-width: 2**(i+7)px)
      width: 100px*i

would yield to

@media (min-width: 256px) {
  .foo {
    width: 100px;
  }
}
@media (min-width: 512px) {
  .foo {
    width: 200px;
  }
}
@media (min-width: 1024px) {
  .foo {
    width: 300px;
  }
}
@media (min-width: 2048px) {
  .foo {
    width: 400px;
  }
}
