How to use SCSS/SASS to increase animation-delay for concurrent divs

I use this mixin:

@mixin delay($rule, $number, $value) {
  @for $i from 1 to ($number + 1) {
    &:nth-child(#{$i}) {
      -webkit-#{$rule}-delay: (#{$i*$value});
      #{$rule}-delay: (#{$i*$value});
    }
  }
}

.results div{
  @include delay(animation, 8, 0.25s);
}

This way you can re use it transitions too.

You can use a for loop in Sass to do this like so:

@for $i from 1 to 10 {
  .results div:nth-child(#{$i}) { animation-delay: $i * 0.25s; }
}

Then you can do it for any number of divs by making the 10 to what ever you need.

@for $i from 1 through 10 {
  .results div:nth-child(#{$i}) {
    -webkit-animation-delay:(#{$i*0.1s}); 
    animation-delay:(#{$i*0.1s}); 
  }
}

Better solution... I tested and it works ;)
