If it does (and I’m not sure why it wouldn’t) there are some interesting
implications. In Firefox 38, setting ::before and ::after on a flex item,
then giving the flex item display:contents appears to promote the ::before
and ::after to be flex items:

body {
  display: flex;
div {
  display: contents;
div::before {
  content: "foo";
  flex: 1;
div::after {
  content: "bar";
  flex: 2;


I assume this would also work for promoting these pseudos to be grid
items, where you could place the pseudos along with other children in
separate grid areas.
