The Freshcaller user interface (UI) is built on a modified version of the Bootstrap v3.3 framework.
  For better user experience, an app's UI should be consistent with the Freshcaller UI.
  This section provides information on the default Freshcaller UI stylesheet and how to include a custom stylesheet.

    Note: If you use a custom CSS, ensure that the class names of the UI elements used in the app match those used by Bootstrap.

For an example built-in styles usage, see the sample HTML code and output.
  To override the built-in styles with a custom CSS, in the HTML code, after <link rel="stylesheet" href="https://static.freshdev.io/fdk/2.0/assets/freshcaller.css">, add the reference to the custom CSS.
