In that case, "whatever axis is vertical" doesn't help me. I would need a 'bg-pos-block' and 'bg-pos-inline'. Yes, we're also adding those. > Do you have a different use case in mind, where 'start' would need to be used instead of 'top' or 'right', but the axis you applied it to would always be vertical? Or alternately horizontal, if you used 'bg-pos-x'? It seems to me that if you didn't care which logical dimension it was aligned to as long as it was the start of the vertical, you would just use 'top' instead of 'start'. Yes, the use-case is when, for whatever reason (watermarking?) you want the image to show up at the top of the element, but also at the "start" of the text, whichever that is. So you'd do "background-position: top start;". ~TJ
