Show disc number titles on a track list (CSS)

Show disc number titles on a track list to break the list into sections.

There isn't currently a setting to do this, but can be achieved with some custom CSS:

#track-000001::before {
  content: 'Disc 1';
  white-space: pre;
  margin-bottom: 1.429em;
}

#track-000022::before {
  content: 'Disc 2';
  white-space: pre;
  margin-top: 1.429em;
  margin-bottom: 1.429em;
}

Where the number following track- represents the track ID (this can be gathered from the URL on the track page on Ochre).
