+For displaying code in a list item, you have to be aware of the indentation, as stated in this [Stackoverflow answer](https://stackoverflow.com/questions/34987908/embed-a-code-block-in-a-list-item-with-proper-indentation-in-kramdown/38090598#38090598). You must indent your code by **(3 * bullet_indent_level)** spaces. This is because kramdown (the markdown engine used by Jekyll) indentation for the code block in lists is determined by the column number of the first non-space character after the list item marker. For example:
+
+```markdown
+1. We can put fenced code blocks inside nested bullets, too.
+ 1. Like this:
+ ```c
+ printf("Hello, World!");
+ ```
+
+ 2. The key is to indent your fenced block in the same line as the first character of the line.
+```
+
+Which displays:

+1. We can put fenced code blocks inside nested bullets, too.
+ 1. Like this:
+ ```c
+ printf("Hello, World!");
+ ```
+
+ 2. The key is to indent your fenced block in the same line as the first character of the line.

 By default, it does not display line numbers. If you want to display line numbers for every code block, you can set `kramdown.syntax_highlighter_opts.block.line_numbers` to true in your `_config.yml` file.
 
 If you want to display line numbers for a specific code block, all you have to do is wrap your code in a liquid tag:
