Whether or not <BR> has content is not important for CSS. <IMG>
doesn't have content either. Neither does the sequence
`<EM></EM>'. For CSS an element is just an element; it has a name,
optionally an ID, zero or more attributes, and zero or more characters
of content. (In other words: CSS deals with the abstract document
tree, not with the incidental markup.)

If I interpreted the original poster's code correctly, the poem is
supposed to look approximately like this:

    in Just-
    spring       when the world is mud-
    luscious the little
    lame baloonman

    whistles     far     and wee

Here are two alternative ways of expressing the layout of the same
poem. This time using the STYLE attribute only, to keep the
information local. Which is preferred depends on one's taste:

    <p>in Just-<br>
    spring<br style="display:inline;width:7em">when the world is mud-<br>
    luscious the little<br>
    lame baloonman

    <p>whistles<br style="display:inline;width:5em">far<br
    style="display:inline;width:5em">and wee

or:

    <p>in Just-<br>
    spring<span style="word-spacing:7em"> </span>when the world is mud-<br>
    luscious the little<br>
    lame baloonman

    <p>whistles<span style="word-spacing:5em">
     </span>far<span style="word-spacing:5em">
     </span>and wee

and there are many other ways as well.

The CSS1 draft notes that changing a block element to an inline
element, as I did for <BR>, is dangerous, since the first generation
of browsers may have that property hard-coded. Still, it should work
eventually.

The last example with <SPAN> shouldn't be problem. The whitespace
inside the element (note that I deliberately put extra, collapsible
whitespace characters there) represents a word separator, which is
then stretched to 5em.
