It looks like if a <code> block is bigger than the page itself, prince doesn't render the page correctly. Attached is a screenshot.

There must be some other CSS being applied in this case, it is being floated, absolutely positioned, or formatted as an inline-block?

It's inside of a <pre> tag. Could that be it?

It should still break properly across pages. Can you load the HTML in a browser and use DOM inspector to see what CSS properties are being applied?

I've got this for the css:

pre code,
.hljs {
  display: inline-block;
  padding: 7px 15px;
  background: #002b36;
  color: #839496;
  width: 100%;
  margin-bottom: 15px;
  box-sizing: border-box;
}

and html:

<pre><code class="lang-python3">&gt;&gt;&gt; <span class="hljs-reserved">import</span> cards
&gt;&gt;&gt; game = cards.OldMaidGame()
&gt;&gt;&gt; game.play([<span class="hljs-string">"Allen"</span>,<span class="hljs-string">"Jeff"</span>,<span class="hljs-string">"Chris"</span>])

The "display: inline-block" is causing the problem. Prince can't break a single line of text across pages, and notionally that's what an inline-block is. If you can change it to block, then it should be fine.

Worked! Thank you so much!
