Applying @if Statement for Group Box

Hello,  I am trying to make it where when a groupbox is opened, it will turn the header green and when closed red, I am trying to determine where to insert the @if statement in the custom sass document, so that it can respond to  aria-expanded="false" status in the code.  If there is a better approach to handle this, please let me know.  Thank you in advance!
