I have the Ethos Stack - Agency demo - Home Page.
There are 3 Sections (Services, Office, Contact), that have stock background images.
When I edit the page using Cornerstone, and scroll up in the preview window, the background images remain fixed, while the elements in those sections scroll. (Which is a really nice transition look).
But, when I publish the page on my site (www.vapeshopvideo.com), the background images in those 3 section are not fixed, and scroll with the elements.
I did check the online demo on theme.co, and the agency demo also has the background images scrolling with the elements.
Why are the background images fixed in Cornerstone, but not live?
How can I made them fixed position?
