For example, the following removes the author and date/time stamp of posts and pages, but a small "clock" icon remains and can't get rid of it.
.entry-date { display: none !important; }
.fa-fa-clock-o { display: none !important; }
FireFox "web-developer tools" let you see what everything is called, but I don't understand what to do in this case where the icon seems to be a child of something.
TIA.
