Might be more aesthetic to do a div class="card-header" in place of the h3?

[jvanderaa]

If we do the card-header then we should probably do it in the rest of the sections too. Thoughts @glennmatthews ?

[glennmatthews]

I'd be in favor of that, yes. The current styling is very inconsistent with the rest of Nautobot, IMHO.

[jvanderaa]

I'm good by that. I'll be diving in later today looking for a styling guide or how I can make the dashboard page look more appropriate.
