Hi There,
Thanks for posting in!
If you want to use font awesome icons, please use the icon shortcodes. You can see all the icons on this page: http://theme.co/x/demo/integrity/1/shortcodes/icons/. If you are using Cornerstone, you might need to use this format:
[x_icon type=”check”]
You could use them in front of a Custom Headline for example and you would have a similiar effect to what you are looking for I believe.
Ex: Featured Headline Element: `[x_icon type=”check”] Hello World!
`
Hope that helps,
Thanks,
Joao
