Style List Markers in CSS

It’s a perfectly reasonable to want to style the marker of list items. You know: blue bullets with black text in an unordered list. Or red counters with knockout white numbers in an ordered list.

There is a working draft spec that defines a ::marker pseudo-element that would give us this control.

Code language: CSS

/* Not supported anywhere; subject to change */
li::marker {
  color: blue;
}

It’s possible to do this styling now, though, thanks to CSS counters. The trick is to remove the list-style, then apply the markers through pseudo-element counters.

Code language: CSS

ol {
  list-style: none;
  counter-reset: my-awesome-counter;
}
li {
  counter-increment: my-awesome-counter;
}
li::before {
  content: counter(my-awesome-counter);
 
  /* Style away! */
 
}
