corner() takes a single string argument:  $('#myDiv').corner("effect corners width")
effect:  name of the effect to apply, such as round, bevel, notch, bite, etc (default is round). 
corners: one or more of: top, bottom, tr, tl, br, or bl. 
by default, all four corners are adorned. 
width:   width of the effect; in the case of rounded corners this is the radius. 
specify this value using the px suffix such as 10px (and yes, it must be pixels).
