Set properties using mixin

[sudipto-roy]

Not able to set property using mixin parameters.

@mixin set-val($property, $value){
  padding: $value; // works
  border: $(value); // works
  $property: 0; // do not work
  $(property): 0; // do not work
}
.class {
  @include set-val(margin, 0);
}

Sadly, this is not possible.

Sass/Postcss takes an input and outputs something (compiling).
Just like you can´t dynamically change $vars inside media queries.
Modern browser support this using native css variables--var which can dynamically be changed.
However a preprocessor like sass/postcss can´t do that. Its output will always remain static.
