Using CSS
In the <head> of your html, reference the location to bitonics.min.css:
<link rel="stylesheet" href="https://bitonics.net/vendor/bitonics/bitonics.min.css">
In the <body> of your html, place to following html code:
<i class="bt bt-btc" aria-hidden="true"></i>
Using a non existing currency code will result in a nice question mark.
Check out the following examples for various styling:
<span class="bt-stack bt-lg">
<i class="bt bt-square bt-stack-2x"></i>
<i class="bt bt-btc bt-stack-1x bt-inverse"></i>
</span>
<span class="bt-stack bt-lg">
<i class="bt bt-circle bt-stack-2x"></i>
<i class="bt bt-btc bt-stack-1x bt-inverse"></i>
</span>
<span class="bt-stack bt-lg">
<i class="bt bt-triangle bt-stack-2x"></i>
<i class="bt bt-btc bt-stack-1x bt-inverse"></i>
</span>
<span class="bt-stack bt-lg">
<i class="bt bt-shield bt-stack-2x"></i>
<i class="bt bt-btc bt-stack-1x bt-inverse"></i>
</span>
