Every sections receives a data-height for it's height which means you're able to select any height you want. Want if to be full screen? data-height="100%"

Thinking of mobile (parallax needs big images, kenburns is too heavy and video won't autoplay) every section accepts data-bg-image-mobile. It receives a fallback image for smaller devices and will display a normal background image. This will save a lot of bandwidth for your users!
