:future

Limited availability

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

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

css
:future(p, span) {
  display: none;
}

Syntax

css
:future {
  /* ... */
}

Examples

CSS

css
