CSS.md#value-formatting Why say Use hex or rgba?

It might be better to say when using rgb( and rgba( to include a fallback, i.e.:

.selector-name {
    color: #ccc; // #ccc = the output color of flattened 20% black on white
    color: rgba(0,0,0,.2);
}

I see that fallback is in https://github.com/LukeAskew/Front-End-Standards/blob/master/Stylesheets/CSS.md#browser-compatibility, but is that the right place?

  2. To provide consistency and predictability.

RGB has better support, that's it. But not major concern.
