Working with transparency

-------------------------

.. note::

   New in version ``0.3``.

If you ever find yourself in need of having a transparent background or

foreground, you can easily do this using the syntax

``rgba(224,224,224,0)``. All this does is effectively adding alpha channel to

selected colour.

The alpha channel value ranges from ``0`` to ``255``, letting you specify how

much transparency/opaqueness you want. For example, to have it at roughly 50%

(more like at ``50.2%`` since you can't use fractions), you would simply specify

value as ``rgba(224,224,224,128)``.
