I have dconf editor but everything is changed in juno. so we cant edit the wingpanels opacity there. if we can, how? i have recently arrived at linux environment so please help me out a bit. thanks
you can modify that panel in apps.css
sudo io.elementary.code /usr/share/themes/elementary/gtk-3.0/apps.css
* Panel *
********/and modify what you want to change Colors, transparency. # 000 is color and 0.0 is transparency.
I recommend you to be very careful since you can break something, also so that you know about how to modify things look for hex codes for colors.
