This is called ScrollToTextFragment. See https://github.com/WICG/ScrollToTextFragment https://github.com/WICG/ScrollToTextFragment I think they just started doing this a few hours ago. I only noticed it in the "Featured Snippet" box. Edit: > I was surprised because Quora can’t know what the search result looked like and so doesn’t know which part of the text to highlight. Did Google at some point stop sending referer headers that include the query? The last time I checked (~10 years ago, admittedly), they did, which was often collected for analytics. Regardless, it's the browser doing the highlighting in this case, not the site itself.
