Gnome terminal CSS for ambiance theme

gnome-terminal.css

/* gnome-terminal */
TerminalScreen {
  -TerminalScreen-background-darkness: 0.95;
  background-color: #300a24;
  color: #fff;
}

TerminalWindow,
TerminalWindow.background {
  background-image: none;
  background-color: @dark_bg_color;
  color: @dark_fg_color;
}

TerminalWindow .notebook {
  border: 0;
  padding: 0;
}

TerminalWindow .notebook tab.top:active{
  padding: 0;
  border-image: none;
  background-color: alpha(red,0.4);
}
TerminalWindow .notebook tab.top{
  padding: 0;
  border-width: 0;
  background-image: none;
  background-color: @dark_b!g_color;
  color: gray;
}

This is a screenshot from Ubuntu 16.04, with Gnome installed afterwards. It shows the gnome-terminal when the window does not have focus. That makes the tab-close buttons and that new-tab button turn light gray instead of dark. Any chance you know how to fix that?

Also, the dropdown button at the right is always this light color.

@AlexHaaniWink Using following css to set the button color:

TerminalWindow .button {
  background-color: #000;
}

This makes the buttons nicer for a dark theme and to use less vertical space:

TerminalWindow .notebook .button,
TerminalWindow .notebook .button:active {
    padding: 2 2 2 10;
    background-image: none;
    border: 0;
}

Do you know how it's possible to know which elements and classes are available?

How can I change the font color in the active tab (I want to make it brighter)?

@AlexHaaniWink Did you ever figure this out? Thanks.

when there is a warning it shows buttons as presented by @AlexHaaniWink in ubuntu 16.04.
