Ah, I stand corrected on this one point. I do see now that it does  
have its own version of what left, right, top, and bottom are  
supposed to do. I suppose a very careful reading might reveal to  
authors what those values do for position:center and how they differ  
from position:absolute. I don't think it is as intuitive, though.
