How to make a styled Markdown admonition box in a GitHub Gist?

Question

I am trying to make a Markdown admonition box such as note box, warning box for GitHub Gist. I do some search on Google I find Python markdown admonition but these admonitions don't seem to work on GitHub Gist.

I have tried following Python warning admonition But this markdown syntax doesn't work on GitHub Gist.

!!! Hello Admonition

I also tried bootstrap boxes like this but it does not have style as expected:

<div class="alert alert-danger" role="alert">
    <div class="row vertical-align">
        <div class="col-xs-1 text-center">
            <i class="fa fa-exclamation-triangle fa-2x"></i>
        </div>
        <div class="col-xs-11">
                <strong>Error:</strong>                   
        </div>   
    </div> 
</div>

Is there any admonition syntax or HTML code method for GitHub Gist?
