Deeper Style Configuration for Requests/Issues

[Zacj Bellot]

I'm super new to all of this. New to Jira. New to back-end configuration. 

I've been playing with the menus and settings. As best as I can tell, beyond selecting certain fields to display/disable, there isn't much available to configure the issue screens in terms of style (color, borders, layout, etc). What do I do to further configure these screens on a more granular level? Any help or resources would be much appreciated.
