I like the idea of being able to declaratively alter my references to 
figures and sections based on where they end up.

.figure {
   float: snap;

a:target-matches(attr(href, url), .figure)
  :target-counter(attr(href, url), page, same) {
   content: "on this page";

a:target-matches(attr(href, url), .figure)
  :target-counter(attr(href, url), page, next) {
   content: "on next page";

a:target-matches(attr(href, url), .figure)
  :target-counter(attr(href, url), page, previous) {
   content: "on previous page";

a:target-matches(attr(href, url), .figure) {
   content: "on page " target-counter(attr(href, url), page);

Being able to tell whether the figure was floated in the end or not 
would also be useful.

a:target-matches(attr(href, url), .figure:not(:floating)) {
   content: "below";

That does invite you to wonder what

   :floating { float: none; }


   a:target-counter(attr(href, url), page, same) {
     counter-reset: page;

might mean, though.
