Here is what I'd do, start from here: <div class="comment level0"> <a class="up"></a> <a class="dn off"></a> <h1>title</h1> <p class="minus2">comment here</p> </div> Then apply styles at will, increase padding per level and dimming per negative karma. I bet code size decreases while readability increases.
