HTML 5 viewing

I created a theme and created a course it works great in normal browsers but once I tried to view it on my iphone the interactive portion wasn't showing nor working. I saw the slides and the video but the "info" icon weren't popping up. Is this an html 5 issue? HTML 5? Does it support interactive? Please let me know?

The user clicks on the info icon and a layer pops up showing detail in the video. It works awesome on the computer but on my iphone I only see the video I cant click the icon and see the layers.
