The :past CSS pseudo-class selector is a time-dimensional pseudo-class that will match for any element which appears entirely before an element that matches :current. For example in a video with captions which are being displayed by WebVTT.

:past(p, span) {
  display: none;
}

Syntax

:past {
  /* ... */
}
