I just saw the demo of Crio and it looks like the video background option is only for the header. What I meant was how do I had a video as background in a section in any page, not as header.

Hi Jesse, do we have an estimated date for the release of Crio?
Also when you add the video as background to the header in Crio, will this video be in every page or can you choose in what page to appear? 

I opened an other question ( https://www.boldgrid.com/feedback/communities/20/topics/4256-my-background-pictures-dont-scroll-on-mobile-devices-help) but it wasn't answered.

The problem is not only that the image in the background doesn't resize but also if I put as fixed it will still scroll with the page instead of having the content scrolling over the image. This happens only in the mobile device. In the desktop will work perfectly.

I tried this code on "Monument" theme but it says there is an error and must be fixed before changes can be saved.
