Theme demos?

Hi guys,

I’m never going to be able to build a site as good as the one on the demo you have for arcane. So I need help with a few things:

1. How do I install a demo copy of the site? to look like you guys have on your sales pitch here https://skywarriorthemes.com/arcane/

2. How do I get full width image spacers? On the demo landing page there’s images that stretch the full width of the page however when i go into WPBakery and use the “add full-width space” and set it to 100%, still does not work.

3. What’s the main way of editing this site? so organising content etc, is it through WPBakery??
