Possible to do this scrolleffect without 100% width and height on scollsections?

JavaScript

So, I’m making a website that will present a new app, and the client really likes the scoll effect on the new apple iphone 5c website. I have found a plugin that does that exact effect. However… I would like the effect but I do not want every section to be 100% viewport width and height. Is it possible to make this?

The plugin i’m using is this http://www.thepetedesign.com/demos/onepage_scroll_demo.html#

and it’s css looks like this:

body, html {
  margin: 0;
  overflow: hidden;
  -webkit-transition: opacity 400ms;
  -moz-transition: opacity 400ms;
  transition: opacity 400ms;
}

body, .onepage-wrapper, html {
  display: block;
  position: static;
  padding: 0;
  width: 100%;
  height: 100%;
}

.onepage-wrapper {
  width: 100%;
  height: 100%;
  display: block;
  position: relative;
  padding: 0;
  -webkit-transform-style: preserve-3d;
}

.onepage-wrapper .section {
  width: 100%;
  height: 100%;
}
