I was trying to change the theme of panel button : calendar
And here is my attempt
I need to make calendar looks like this, specifically how to alter the appearance of the first line or second line in StLabel
..
CSS class name :
#panel .panel-button StLabel
version: 18.10
theme: arc-dark gnome shell theme
Best Answer
The style_class for this particular field is
#panel .clock-display
examples:
In my opinion and after several attempts,
since 1st line & 2nd line are from
Clock Override
Extension..the alteration you are looking for 1st line & 2nd line is not possible unless this extension or gnome-shell system files are edited to match to separate those two lines.
