made all font-family to use open-sans. Fix for #27

[spritle]

@despo, it will make the site to use open-sans everywhere. It does look good and uniform.

Let us know if it make sense.

@spritle this looks good, thank you. :+1: :star2: I'll merge when you get back to me.

Two options:

• you can take this merge, but it will affect if you ever want to update foundation.css
• we can revert changes made to foundation.css but have certain elements (body, h tags, and p) used in foundation.css to be override by style.css. In layout style.css appears after foundation.css.

does it make sense ?

[despo]

@spritle I'm not keen in option one, in case I forget or get stuck when I want to add something new. Option two sounds good. A third option would be to start using sass (and foundation-sass) so different variables can be customised.

[spritle]

@despo I went for option 2 for now. Revert the foundation.css to its previous state. Override'd .label and .button of foundation.css via stye.css
