Adding Margins to Library

[TomGeshury]

This addition allows dynamic adding of margins by offsetting width that it normally removes. By doing this, this change allows more flexibility for users to style activeStyles.

Problem attempted to solve:

I haven't found any bugs except with the current implementation of border, the library will not work. However, I still believe this is needed because the current implementation of border is very hard to manage i.e. when the desired outcome was to alter the width of it as well as center that border.

Let me know if you have any thoughts
