## Code blocks in list using `highlight` shortcode {#code-blocks-in-list-using-highlight-shortcode}

Reference: `hugo` Issue #[4717](https://github.com/gohugoio/hugo/issues/4717), `ox-hugo` Issue #[161](https://github.com/kaushalmodi/ox-hugo/issues/161)

<div class="red note">

Switched from exporting the `highlight` shortcode to exporting the
code fenced blocks with attributes. These code fences are support by
Hugo + Goldmark since v0.60.0.

**Below notes are now outdated and thus grayed out.**

<div class="gray">

This is an **upstream** bug in `hugo` as of 2018-05-12. The issue is
that when the code blocks in `highlight` shortcodes are inserted at
the required indentation levels in lists.. so that they get rendered
**in** the list at **that** indentation level, those indentations are not
removed by `hugo`, and thus become part of those code blocks.

Also, related to this issue, it can be seen that all such indented
code blocks have an empty second line too, probably just due to the
unremoved indentation on the last line of those code blocks.

In the above section, the same code blocks are code-fenced instead of
using `highlight` shortcode, and the extra indentation is not seen
there.
