Improve: Remove extra styles, Add vars for units

[tpkahlon]

• Declaration of units in Vars for more control in future iterations
• Remove unwanted style tags in current iteration to tone down CSS
• Split display attribute in its own context for easier declaration on tags across site

Thanks for your contribution. While I'm sure some folks might appreciate this approach, I'm going to stick with hard coded values right now. They can easily be overwritten by custom CSS and keep the library easy to learn.
