I think it's pretty obvious which behavior I think we should standardize on here, but I'll spell it out :-). Adopting B everywhere has the following advantages: -- Matches window.pageXOffset in all browsers -- Matches event.pageX in all browsers. A and C do not match any of the event attributes. -- Matches 2/3 browsers and spec for window.scrollX -- For element.scrollLeft, no worse on browser compat than A or C. -- Avoids making direction logical, which while appealing in some ways occurs nowhere else in CSS Whichever behavior we choose breaks some properties that hold in LTR pages. B preserves the "direction increases to the right" property and the "set position to 0 to get the initial, logical start position" property. If we choose A or C for any attributes then we will have inconsistency with window.pageXOffset and event.pageX (at least) and at least two browsers will have to change behavior for each attribute.
