css - How to pass a code block to a function or mixin in Stylus -

i'm moving sass stylus , have lots of mixins pass in code block accessible inside mixin @content.

for example...

@mixin respond-min($width) {     // if we're outputting fixed media query set...     @if $fix-mqs {         // ...and if should apply these rules...         @if $fix-mqs >= $width {             // ...output content user gave us.             @content;         }     }     @else {         // otherwise, output using regular media query         @media , (min-width: $width) {             @content;         }     } }  @include respond-min($mq-group2) {     & {         border: 1px solid green;     } } 

i want convert above code stylus, main problem far been how pass code block mixin stylus doesn't appear have feature.

is there alternative solution?
