How can I make a full width slider like your demo?
It's easy! Edit your home page and from "Page Attributes" section, choose "Full Width Slider" as you page template.
Then go to Revolution Slider and edit your slider. In "Slider Layout" choose "Auto Responsive" and change "Grid Height" from "300px" to a larger number like "450px".
Save your settings and now you'll have a full width slider on your homepage.
