The generated style.css defines the font face
Beaterial.
You can either copy the contents of style.css to your
own CSS or link to it in your HTML like so:
<link rel="stylesheet" href="style.css">
The second line is for enabling early font downloads.
Use the CSS class icon to apply the generated font to
any text:
<span class="icon"></span>
You could change the size of the glyph using the
font-size property in CSS:
.my-size {
font-size: 2em;
}
<span class="icon my-size"></span>
