Hey,
There may be a few methods to inject JS/CSS into the views,
The quickest way, in my opinion, would be to include a custom .js file into the detailviewdefs.php file
I’ve written up a post about this previously
(This is re: editviews, but the steps will be similar): How to remove "Resource List" in Project's edit view?
As well as there being some tutorials online, such as: https://www.youtube.com/watch?v=ZuIKR4ts8Sw
This will let you target the CSS elements more directly
Alternatively, you could create a custom Detailview, and modify how it renders the field Here are some links regarding changes possible, that hopefully point in the right direction:

Those are the two methods I can think of at the moment, unless any other users have some ideas?
Let us know how you get on!
