We do not have a built in system for adding a video background, but I imagine that it should be possible using code. I do not have code handy at this time. Personally I find moving backgrounds distracting. Parallax is also less in favor now. We do have some parallax effects in the new Websitebuilder, but again, you want to be careful with it's use as there have been some people that have reported feeling ill when viewing parallax sites. Parallax can also reduce site performance and be harmful to your SEO.
Drue, Thank you for your reply. I like how Maurice worded what he said. "modern bells and whistles" is what I am looking for. I am a custom manufacturer, video expresses a new depth in a visual expression that I really want to utilize. Do you see any cool new options in the near future for sitebuilder? For the record, I have used Homestead for more than 15 years and I haven't really seen any major, modern changes to design options. This would be HUGE to me. Please advise.
