Help with page scaling

Link- http://codepen.io/codejsp/pen/MJVYMV
Can’t figure out whats causing my page to scale down when I change screen sizes. Is it my max-width? Should I change it to just width? or use both?

its because you use vw as your font size unit

Ah ok I see. Just found out about vw today and was trying to implement it. Good to know, thanks!
Follow up question: So should I use vw to size my wrappers/body/etc?

No, I think its not a good idea. Instead you should use media queries for divs.

You can size your content with the bootstrap grid system. Read more about it here: http://getbootstrap.com/css/#grid
