That method generates HTML with CSS classes. Hence you'll need the style sheet file

<div class="highlight"><pre><div id="lc1">def chunks(iterable, length=2, fill=False, filler=None, drop_incomplete=True):
</div><div id="lc2"> &quot;&quot;&quot;Iterate through iterable in chunks&quot;&quot;&quot;

</div><div id="lc4"> while True:
