I just can’t understand why such information is so meaningful to show public at all. It could be personal, if there is some situations where it is needed.
This is again a solution that should be done using a component/plugin.
CSS is made for a tool to change look. Not hiding functionalities. I know some will upset now but everytime when CSS fix is needed it tells more bad UI/UX-desing or lazyness of devs than anything else. Plus every CSS changes increase the possibility of conflict because no one can’t remember all made changes.
Edit:
And before someone else points this out: yes, using components/plugins will increase risk to fall in same swamp where WordPress-world lives. Genarally speaking this is loose/loose-situation, kind of.
