	<div class="alert alert-danger">
	The `.env` file is meant for development environments only. While it could theoretically be used in production this is *not* recommended, and should only be used as a last resort in hosting environments where setting server level or true environment variables is not an option. Please see the documentation for your web server for more information. E.g. [Apache](https://httpd.apache.org/docs/2.4/mod/mod_env.html#setenv)
	</div>

This issue can be solved by either not using markdown-syntax inside of HTML-elements or by using a markdown-engine which supports Markdown-syntax inside of HTML.

In Kramdown, for example, you can use markdown-language inside of HTML-elements by adding a markdown="1"-attribute to the HTML-tag:

### Warning

<div class="alert alert-danger" markdown="1">
Markdown is **supported** inside this html-tag!
</div>
