Below CSS is for reference. This is just a talk page; so none of this does anything here.

opacity
Value is a number from 0.0 (transparent) to 1 (opaque).

Effects the whole element it is assigned to and all descendants.

To make a transparent background, maybe (a) use a PNG with desired transparency as a background image, or (b) position a non-descendant element over a transparent element.
