Uniform already handles this theme. Scroll down to the bottom of the page and there are three pre-made Uniform themes listed: "Uniform Default," "Aristo," and "Agent."
That's what I meant. With Uniform already styling forms element in Aristo style and JQuery UI now with a matching look, I don't have to waste too much effort on intranet apps...
But Uniform only styles selects (drop downs), checkboxes, radio buttons, and file upload inputs. jQuery UI could nicely compliment Uniform by styling everything else.
