I'm not able to adjust the transparency of wingpanel using gsettings/tweaks. Can someone help me out. Thanks in advance.
gksu scratch-text-editor "/usr/share/themes/elementary/gtk-3.0/apps.css" in terminal and go search pannel class in the css file, there u can set the colors, opacity and so on. This is what I did today!
In case u dont have gksu, type
sudo apt install gksu
DON'T forget to REBOOT !
This is set in the gtk theme now.
