Is there some trick to using this selector? I tried it with Internet Explorer 11 and Chrome 60; neither worked. I have tried on both div and p elements in a manner similar to the following: When using the above selector, all properties I attempt to set are "crossed out" (ignored) by the browser. When I remove ":empty", it works just fine; so it isn't being overridden by anything.
