Customize preview with icon fonts and custom CSS


#1

In StackEdit v4 I can make the preview show fancy things like:

image

using this markup:

 <div class="alert alert-success"><i class="icon-ok"></i> **SUCCESS:** Markdown formatting _is_ supported here.
 </div>
 
  <div class="alert alert-info"><i class="icon-lightbulb"></i><strong>INFO:</strong> Markdown formatting _is_ supported here.
 </div>

 <div class="alert alert-warning"><i class="icon-right-hand"></i> **WARNING:** Markdown formatting _is_ supported here.
 </div>

 <div class="alert alert-danger"></i><i class="icon-attention-alt"></i>**DANGER:** Markdown formatting _is_ supported here.
 </div>

> <i class="icon-quote-left"></i> The secret to creativity is knowing how to hide your sources.

How can I add customizations to the StackEdit v5 Preview pane to handle icon fonts and custom CSS?
