instead of using br's, do it the more modern way, and add a margin to the paragraph tag (or whatever tag is appropriate).
something like:
<p style="margin-top: 2em;">Whatever paragraph text.</p>
Even better would be to put a proper rule in your css file, and add a class to the tags you wish to have the extra space.
something like:
<p class="prettier">Whatever paragraph text.</p>
and in your css file:
p.prettier { margin-top: 2em; }
Well, I hope you get the idea. If you can do it through CSS, you can easily change it, and everything will automatically be the new way, rather than going back and changing each one manually. Ken what I mean Jock? :)
