Transparency for indicator applet complete

Hello all,
I am trying to make the top bar transparent, including the indicator applet. I reviewed both of these threads:


But when I change to this, for example:

#fast-user-switch-menubar {
background-color:rgba(0,0,0,0.4);
}
#fast-user-switch-applet {
background-color:rgba(0,0,0,0.4);
}

Nothing happens. Am I changing the correct values? I am looking to get 60% opacity, so I assume .4 would correlate to that? Any help is appreciated...

So i've got the opacity down, turns out there was a background image setting. But my indicator applet either has a border that is black at the bottom, or is about 1 pixel short from meshing with the rest of the panel. I set the border-bottom-color to the same as the rest of the panel, but it still remains....any ideas Ubuntu MATE world?

I have this in my ~/.config/gtk-3.0/gtk.css:

#fast-user-switch-menubar  {
  background-color:rgba(0,0,0,0);
}

The transparency level is set in the properties of the panel.

Don't forget to reboot to apply the changes.

Thanks! I thought that it would be a decimal between 0-1 for the transparency, that's what one of the other threads eluded to when another member posted an example. But that works! I still have the pesky ~1 pixel gap at the bottom of the indicator applet...
