Remove use of px from css/styles

[MikeNeilson]

Component to be refactored
CSS or direct styles

Purpose of refactoring
using px, outside of media selectors where it;s the only way, makes too many assumptions about the user setup and font size desires.

all sizing constraint should use relative sizing such as em, vh, etc.

Proposed method
go through custom css and styles and alter or justify specific px usage.

Additional context

Replace px with other units in css note that the relative units such as rem, em, vw, vh, and percentage (%) this is my suggestion
