Answer 1

If you want to output a numbered list, the best approach is to make use of <ol> tags but if you can't modify your HTML and still need to output as a numbered list, you can make use of CSS counters to achieve the numbered list behavior.

body {
  counter-reset: esum;
}
.esum {
  position: relative;
  counter-increment: esum;
  padding: 10px;
}
.esum:before {
  content: counter(esum)".";
}

<div class="esum"><span id="1430568488933" class="tbold">nde</span>
</div>
<div class="esum"><span id="1430568576033" class="tbold">ca</span>
</div>
<div class="esum"><span id="1430568582173" class="tdel">tim</span>
</div>
<div class="esum"><span id="1430568582173" class="tins">Ó</span>
</div>
<div class="esum"><span id="1430914284123" class="tdel">non</span>
</div>
<div class="esum"><span id="1430914309275" class="tdel">cu</span>
</div>

Answer 2

CSS

.esum {
  display: list-item;
  margin-left: 1.5em;
  list-style-type: decimal;
}
