RE: [css3-images] linear-gradient keywords and angles are opposite

You've omitted that those are abbreviated forms of the property.

The full form of those values is:
(a) background-position: left 20px center;
(b) background-position: right 0px center;

The full form makes it much clearer how it behaves.

You're welcome to critique the abbreviated forms of background-position as confusing, but as a separate matter from the issue I raised with linear-gradient's first parameter.


Also, background-position isn't about extension or direction.  It's about the anchoring of a location within the source image relative to the background-positioning-area.  As such, there's not the same opportunity for confusion as for linear gradients which have both anchoring and direction.
