A quote from a specific user / post gets converted into an <aside> element with the class quote Inside that there are different elements like a div that holds the meta information like user avatar and name and a <blockquote> that holds the actual quote
Something like this:
And that’s what it looks like in html:
<aside class="quote" data-post="2" data-topic="82448">
<div class="title" style="cursor: pointer;">
<div class="quote-controls"><i class="fa fa-chevron-down d-icon d-icon-chevron-down" title="expand/collapse"></i><a href="/t/controlling-text-size-in-posts/82448/2" title="go to the quoted post" class="back"><i class="fa fa-arrow-up d-icon d-icon-arrow-up"></i></a></div>
<img alt="" width="20" height="20" src="https://global.discourse-cdn.com/meta/user_avatar/meta.discourse.org/lll/40/85378_1.png" class="avatar"> lll:</div>
<blockquote>
<p><big></p>
</blockquote>
</aside>
