How to determine the width of the screen inside the function?

Question

Sass

I want to do something like:

@function calc-size($size) {
        @if(ширина экрана < 768) {
                @return $size*1;
        } @else {
                @return $size*1.5;
        }
    
}

How can you achieve what you want in sass?

Answer 1

@media (max-width: 768) {
   @function calc-size($size) {
  }
}
