You could use css margins and offset it in your div.
Code:
// css file - you would need to ajust them for what you want.
.comments { width: 100%; margin: 0 auto; }
.indent-1 { margin-left: 0; }
.indent-2 { margin-left: 20px; }
.indent-3 { margin-left: 40px; }

.indent-1,
.indent-2,
.indent-3 { width: 100%; }

// html divisions
<div class="comments">
    <div class="indent-1">your comments</div>
    <div class="indent-2">your comments</div>
    <div class="indent-3">your comments</div>
</div>
You just need to indent them. You could use a for loop and increment the indent variable.
