How does it work?

By default, when using css modules, you end up with hashes or other long class-names in your bundled css files:

@keyframes _close-card_pzatx_1 {
  /* CSS HERE */
}

._card_pzatx_32 {
  /* CSS HERE */
}

._back_pzatx_49 ._content_pzatx_70 ._close_pzatx_74 {
  /* CSS HERE */
}

By using this module, the smalles possible classname will be used for each "id":

@keyframes a {
  /* CSS HERE */
}

.v {
  /* CSS HERE */
}

.c .s .w {
  /* CSS HERE */
}
