Window::
An X11 window, like the Firefox browser window or a terminal emulator.
+Floating Window::
+A window which "floats" on top of other windows. This style is used by i3 to
+display X11 windows with type "dialog", such as the "Print" or "Open File"
+dialog boxes in many GUI applications. Use of floating windows can be
+fine-tuned with the for_window command (see HTML userguide).

+1. ~/.i3/config
+2. ~/.config/i3/config (or $XDG_CONFIG_HOME/i3/config if set)
+3. /etc/i3/config
+4. /etc/xdg/i3/config (or $XDG_CONFIG_DIRS/i3/config if set)
