Conversion file comparison

Stylus source code before conversion

handleParams(args...)
  args

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

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

Converted SCSS source code

@function handleParams($args...) {
  @return $args;
}

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

.foo {
  @for $i from 1 through 4 {
    @media (min-width: 2 * ($i + 7) px) {
      width: 100px * $i;
    }
  }
}

If you do not want to add the default prefix for your converted @keyframes, please set options.autoprefixer = false

The .vue file before conversion
