@firefoxwebdevs for who's curious, I went and found the real CSS properties Jake got wrong: "pause-after" is for speech-related CSS, it can specify a duration for a pause after a word's been spoken out-loud (
https://www.w3.org/TR/CSS22/aural.html#pause-props). "scroll-target-group" can be used to change the style of certain same-document navigable elements, linked using a hash/id (
https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Properties/scroll-target-group). The latter isn't well-supported right now, but looks very useful!
