The closing tag can be replaced by ``</>``, which revokes all formatting options

It is possible to define your own styles using the class

:class:`Symfony\\Component\\Console\\Formatter\\OutputFormatterStyle`::

Available foreground and background colors are: ``black``, ``red``, ``green``,

``yellow``, ``blue``, ``magenta``, ``cyan`` and ``white``.

And available options are: ``bold``, ``underscore``, ``blink``, ``reverse`` and ``conceal``.

And available options are: ``bold``, ``underscore``, ``blink``, ``reverse``

(enables the "reverse video" mode where the background and foreground colors

are swapped) and ``conceal`` (sets the foreground color to transparent, making

the typed text invisible - although it can be selected and copied; this option is

commonly used when asking the user to type sensitive information).

You can also set these colors and options inside the tagname::
