`:past` CSS pseudo-class

Baseline Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

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 {
  /* ... */
}

Examples

CSS

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

HTML

<video controls preload="metadata">
  <source src="video.mp4" type="video/mp4" />
  <source src="video.webm" type="video/webm" />
  <track
    label="English"
    kind="subtitles"
    srclang="en"
    src="subtitles.vtt"
    default />
</video>
