CSS Vertical Align Trick - SASS Version

Came across this link earlier today, and it was extremely clever.

Here is the SASS version of the CSS displayed there.


.wrapper {
  
  &:before{
    content: '';
    display: inline-block;
    height: 100%;
    vertical-align: middle;
    margin-right: -0.25em;
  }
  .row {
    display: inline-block;
    vertical-align: middle;
  }
}
