CSS for aliases

When adding an alias to a link to a pdf passage I lose my formatting. I’d really appreciate any help on how to edit my CSS to fix this :slight_smile:

Every line below is a link to a PDF. I’ve added the css below to add a purple arrow before a pdf link but when I use an alias I loose the arrow

#hierarchy-editor .rem-container .rem-text .rem[data-rem-tags~=“aliases”] {
color: #B1B1B1;
}

  .rem-reference--pdf-highlight:before {
  	content: " ➼ ";
  	color: #800080;
  	font-style: bold;
 }

What do I need to change to get the arrow back and to set CSS for aliases only. Cheers for any help
