Easiest solution I found was to add a custom attribute based on ondrag[something] events and to then use a CSS attribute selector:

<script>   
  // ===== Drag-and-Drop Functionality ===== // 
  el = document.getElementById("some_id"); 
  el.ondragover  = function(e) { e.preventDefault(); this.setAttribute("data-drag-and-drop-state", "ondragover" );  }; 
  el.ondragenter = function(e) { e.preventDefault(); this.setAttribute("data-drag-and-drop-state", "ondragover" );  }; 
  el.ondragleave = function(e) { e.preventDefault(); this.setAttribute("data-drag-and-drop-state", ""           );  }; 
  el.ondrop      = function(e) { e.preventDefault(); this.setAttribute("data-drag-and-drop-state", ""           );  };
</script>

<style>
  .custom-file-input[data-drag-and-drop-state="ondragover" ] { background-color: green; }
</style> 

This code is only an implementation for CSS effects; include other code where applicable to actually handle the file drop and so on.
