The 'opacity' property is a blunt club that should only be used when
you really want the entire element to be partially transparent.

Like Paul said, if all you want is a transparent background, make a
transparent background.  Either use a PNG image with transparency, or
use the rgba() or hsla() functions to create a partially-transparent
background color.
