Questions about title bar, which is part of the window decoration. If the title bar has an unusual design that may not follow system-wide theme, or has more graphical elements besides window title and window controls, then use 'csd' tag instead.
Title bar includes the application icon (built-in with window menu), application name, and window controls in a traditional desktop environment. Title bar is part of the window decoration and contributes to the look and feel of an operating system.
Title bar should not be mistaken for header bar or the client-side decoration used by some desktop environments and applications. Title bar is handled by the window manager, whilst the latter is handled by the application itself.

- Window (windowing system) on Wikimedia Commons - The illustration of an application window, which includes the title bar and buttons between the window frame and the menu bar
Tag usage guideline:
- For questions about traditional bar that is handled by the window manager, use titlebar
- For questions about single unified bar that includes menu buttons, window title, and window controls all together and handled by the application itself, use csd
Both title bar and client-side decoration include window title and window controls, but title bar does not have menu buttons that otherwise found on the toolbars in a traditional desktop environment.
