I was just wondering if there is any way that one could, using whatever method, automatically insert a <DD>; every new line break (<BR>) automatically. The reason I need it automatically formatted that way, hopefully using CSS, it's so that I can do this to a plethora of text already in the document.

Thanks, in advance!

If I understand what you want to do, you need to get an html editor that has a replace function. then you put this in the text to find field: <br>
and this in the text to replace field: <br><dd>

Of course this just adds an open <dd> tag, you also need the rest of the <dl>(definition list) tags.

Here is a properly formatted definition list:

<dl>
<dt>Cats</dt>
<dd>Furry, annoying animals.</dd>
</dl>
