Create a custom list style with @counter-style
- symbols defines the list counter symbols.
- 
system specifies the algorithm for how to apply the list counter, such as cyclic
- suffix defines the contents between the list counter symbol and the list item content.
Now apply the list style on a list container element with list-style: styleName.
@counter-style emoji {
  symbols: "\2615";
  system: cyclic;
  suffix: " ";
}
article ul {
  list-stytle: emoji;
}
