Re: [xsl] XSL-FO alignment

Hi,
          A Point is 1/72 of an inch. I would say that is kind of a
universally accepted fact. Whether microsoft interprets it differently is a
matter of conjecture.

cheers,

According to XSL-FO 1.0 Section 5.3.2, your specification above
will draw the border *outside* of the parent boundary limits ...
unlike CSS.  This guarantees that the text of the border block
lines up with the text of an adjacent unbordered block.  If you
wanted the border to line up with the text, use margin-left="0pt"
in addition to your other properties.
No, I want it outside of the text. I am basing this fo on a windows
doc and that is what we do.

Then what you have should work.  Because you do not have margin="0pt"
the formatter is supposed to keep the text in alignment with adjacent
unbordered text and draw the border outside the parent area limits.

On a related note, (and maybe someone here doesn't know this) am I
correct in saying that the way word defines points, and even cm
different to FO and everyone else?

No comment ... I do not know the answer.

Firstly, I would am still confused about the difference between
space-before and padding-before and padding-top. If someone could
explain
that to me, that would be great.

The space-before= property defines the space between the adjacent
block area and the area's border rectangle (which is the outside
edge of the border).

The padding-before= and padding-top= both specify the distance
between the area's padding rectangle (which is the inside edge of
the border) and the area's content rectangle.  The only difference
between padding-before= and padding-top= is that the use of
writing-direction-dependent values of before/after/start/end are
portable across different languages while the CSS heritage
top/bottom/left/right are biased to left-to-right/top-down writing
directions.

So for english it does n't matter what I use, but I should probably
use before/after/start/end?

Correct ... but I counsel my students to use before/after/start/end
to be portable.

What about space-* vs padding-*?

I'm not sure what is confusing about my answer above:  they are
different concepts.  There are different rectangles in play in XSL-FO
and I told you above that space-* is outside of the outside edge of
the border and padding-* is inside the inside edge of the border.

I don't know how else to describe it to you.

Then add margin-left="0pt" to ensure that the border does not "push
out" such that its context text aligns with the text of neighbouring
blocks.
That sounds like what I want to do.

Then don't use margin-left="0pt" and a conforming XSL-FO engine will
push the border out leaving the text in alignment with adjacent
unbordered blocks.

I hope this helps.
