Hi there I hope you can help me 
I want to build an website like https://www.tumblr.com/ but with videos in the background.
Now I started to build it in webflow with https://github.com/alvarotrigo/fullPage.js. The videos play in preview mode but if I publish the site (http://akquise-kastanienhof-startseite.webflow.io/) the videos dont start to play 
I tried to build a workaround with the HTML Embed instead of the Background Video tool and with an autoplay in the but still the videos dont work…
Any idea out there? Thank you so much.
