Syntax highlighting code fences causes content to fill page width

support
1

It adds a style attribute to the outer div with a hard-coded width that is the exact max width of the parent element.

No syntax highlighting for code fence:

<pre tabindex="0">
  <code>
    ...

Syntax highlighting for code fence:

<div class="highlight" style="width: 1296px;">
  <code class="language-bash" data-lang="bash">
    ...

I expected this instead:

<div class="highlight">
  <code class="language-bash" data-lang="bash">
    ...

This causes layout problems for content.

Edit:

$ hugo env

This happens with footnotes too:

<div class="footnotes" role="doc-endnotes" style="width: 1296px;">
  <hr>
  <ol>
    <li id="fn:1">

I cannot reproduce either of these behaviors.

Are you using someone else’s theme?

My apologies! It seems a bug in a script was the culprit in both cases. It took a while to track down.
