I am fairly new to wordpress and I am using custom meta boxes. I really like the cmb2 plugin to help with creating custom meta boxes but I am wondering how to layout the fields in my meta boxes since I don't want them to be put in a straight list.
Since the generated output has lots of css classes attached I reckon that I am supposed to override the css as my needs dictate. That would be fine if I knew where to put my css. I don't suppose I should edit cmb2.css directly.
Can someone please explain to me what is the preferred way to add my css so that it is picked up in my custom meta boxes?
