How do I change the top bar font in GNOME 3.30.1?
to make entire top bar items size:
change the content in your gnome-shell.css file under .themes folder like below, put any value for your preferred font-size.
/* TOP BAR */
#panel {
background-color: rgba(39, 42, 42, 0.85);
/* transition from solid to transparent */
transition-duration: 250ms;
font-weight: bold;
height: 2em;
font-size: 10px;
}
