css

How would this construct look like in SASS?
Does it read like this? When hovering over a pseudo-element, toggle the radio input to - selected.

input[type="radio"]:checked + span::before {
  background-position: 0 -12px;
}
.checkbox[type="checkbox"] + span::before {
  background-position: 0 -24px;
}

input[type="checkbox"]:checked + span::before {
  background-position: 0 -36px;
}

input[type="radio"]:checked 
  & + span 
    &::before 
      background-position: 0 -12px 
.checkbox[type="checkbox"] 
  & + span 
    &::before 
      background-position: 0 -24px 
input[type="checkbox"]:checked 
  & + span 
    &::before 
      background-position: 0 -36px
