I'm not sure you need javascript here. And I'm not sure why making your cats transparent helps, @ALHAUS. (You're just making your cats disappear, not the comma.) You can actually target the non-linked text, i.e. the comma, in that span with this CSS. The second bit is just making sure your cat doesn't disappear. You just need to fill in your initial color there. Mine is #00bac0.
.summary-metadata-item:not(a) {
color: transparent !important;
}
.summary-metadata-item a {
color: #00bac0 !important;
}
