To include custom CSS I think you’ll need to get into theme development. You can create a custom theme and then add your css to it so that the page will pull in those styles.
Directions on custom page themes:

Do you know how to deal with css on [mautic.com](http://mautic.com) where you can’t have custom themes? I have the same issue with the css not being loaded.

Thanks Chad. I’ve done that already, but it’s been a couple of days with no response. So I figured the community forum might be quicker to respond 🙂
