Re: position= and blocks (was And operator usage in XS

Hi Eliot

My reading of 7.5.1 in the spec about absolute-position was that the block-container was offset from the containing area, not the
containing reference area, although what you say about a block not
establishing a reference area makes sense.

In 7.2 the "containing block" is described as the nearest ancestor
block area which is not a line area, and in the definition of "left"
in 7.5.5. the offset specified by left is said to be from the
"containing block", which I take to mean the immediate parent block,
not the reference area.

I have the feeling I am missing something - can you point me to
somewhere else in the spec where it says a block is positioned
relative to the containing reference area as opposed to the
containing area ?

 "Each area has the traits top-position, bottom-position,
 left-position, and right-position which represent the distance from
 the edges of its content-rectangle to the like-named edges of the
 nearest ancestor *reference area* (or the page-viewport-area in the case
 of areas generated by descendants of formatting objects whose
 absolute-position is fixed); the left-offset and top-offset determine
 the amount by which a relatively-positioned area is shifted for
 rendering. These traits receive their values during the formatting
 process, or in the case of absolutely positioned areas, during
 refinement."
