Sort of but not really. What you are saying above is "everywhere you
would have used <body>, use <center> instead." The problem with that
is that <center> doesn't support the bgcolor attribute; there are only
a few things that do.
The style system is pretty limited in this respect ATM; what you'd like
to say is something like
(gnc:html-document-set-style!
doc "body"
'attribute (list "bgcolor" bg-color)
'extra-markup "center")
which would render to
<body bgcolor=bg-color><center> .. body ... </center></body>
and of course if you had set some style for <center> it should get
rendered appropriately.
An alternative would be to have top-level support for centering in
style objects:
(gnc:html-document-set-style!
doc "body"
'attribute (list "bgcolor" bg-color)
'center #t)
I've been thinking about adding more top-level style primitives so we
can do things like add a background color to paragraphs (which can't
get one with normal HTML, but could if we put them in a table, meaning
the style system would magically add tables where you need to get
background colors).
Neither one would be terribly hard to add (I don't think). I'll have
a look at it today.
It might be easier to use a top-level table in the meantime. <td>
supports centering and bgcolor.
b.g.
