I recently tried to use this code to generate customer containers. The headers and code fence work without problem. Please let me know if I am doing something wrong:

    var pipeline = new MarkdownPipelineBuilder().UseAdvancedExtensions().Build();
    string tempDescription = @"
### Header 3
###### Header 6
Plain text

\```
Code fence
\```

:: Custom Span Container ::

:::
Custom Div Container
:::

";
    Description = Markdown.ToHtml(tempDescription);

The value of Description's output is below:

<h3>Header 3</h3>
<h6>Header 6</h6>
<p>Plain text</p>
<pre><code>Code fence
</code></pre>
<p>:: Custom Span Container ::</p>
<p>:::
Custom Div Container
:::</p>
