To define a grey semi-transparent background on a given element one
could use the following rule:
.semi-transparent {
background: url('images/semi-transparent.png') grey;
background: rgba(50%,50%,50%,0.5);
}
This is supposed to define a double-fallback:
* browsers that do understand
Jørg,
The parsing logic is sound since browsers that don't understand a given syntax
on a rule will ignore it, and since the rule declares the entirety of the
background property, those that can parse rgba syntax will overwrite the
background image defined previously with the implicit 'none'
