Adding fontawesome to shortcodes ultimate tab

Question

I'd like to add a fontawesome icon to a shortcodes ultimate tab title.

When I try to do it inline

<i class="fa fa-500px"></i>

nothing comes up. Is it possible, either using CSS or some other means?

[font-awesome-icon] Tab text 1

[font-awesome-icon] Tab text 2

[font-awesome-icon] Tab text 3

Answer 1

For using shortcodes, there is a plugin which fetches the latest font awesome icons:

It works like this:

[icon name="fa-flag" class="fa-2x fa-spin fa-border"]

They have also alternatives syntaxes for previous versions (with the icon- class names).
