CSS3 Rotational Transforms and DOM Positioning using jQuery.offset()
The actual position of a rotated element relative to another element depends on the point of
origin used to rotate the element. Additionally, jQuery offset() uses getBoundingClientRect()
as a starting point to calculate the top/left point of an element. For a rotated element, the
top/left will not be on the object nor will it be a point used in the positioning of that
object when setting CSS styles. Compare this to
using css() to position a rotated element.
