Icon Library

[tmeehan32]

My team is attempting to update some of the icons currently on our site, but we can only update based on the icons name or its the corresponding number (for example: light-bulb, e870) 

Where is HubSpot can I find this library list so I know what icons I can choose from?

I believe you're referring to font-awesome which is built into some HubSpot themes. Here's their older site: https://fontawesome.com/v4.7.0/

You'll probably need to update the link to the icon library in order to use the new ones, since they released this last year.
