As for how to format without CSS, have a look here
and other sections of that page.
In general: use "height" for vertical space above an element, "width" for first line indent, "<blockquote>" for wider left margin (cannot be nested). For poetry I do:
<p width=2em height=1em>“You are old, Father William,” the young man said,</p>
<p width=4em height=0em>“And your hair has become very white;</p>
<p width=2em height=0em>And yet you incessantly stand on your head—</p>
<p width=4em height=0em>Do you think, at your age, it is right?”</p>
