For a project, I had to compile SCSS code to CSS. Everything seemed to work, except for a @for loop similar to this :

$base-color: #036;

@for $i from 1 through 3 {
  ul:nth-child(3n + #{$i}) {
    background-color: lighten($base-color, $i * 5%);
  }
}

This loop hasn’t been compiled at all to CSS, as CSS does not loop though selectors. But is there a way to loop this code with JavaScript ?

    Not sure what issue you had, but the very same code from OP just worked for me on the site linked in the other comment…

      Yes, I should have shown the real @for loop, because in my case the loop number is unknown (it’s a variable), so the compiler has trouble compiling it.

      I didn’t post this is in the right place. I basically need JavaScript code to replicate this SCSS loop in a way that I can loop though this element with an unknown number of times (a variable that can change according to an array.length for instance).
