I'm playing video on a website. The HTML5 <video> player is housed within a container div which positions it centrally. On most browsers when a user clicks full screen the video plays full screen in the browser without issue, but in Safari on OS the video is positioned half off the screen - I can only see the bottom 50%.
I suspect this is because the <div> container has CSS position:fixed and top:50% height:auto but I can't work out what I need to do to correct for this problem which only seems to occur in Safari.
I can't find any guidance on the web or evidence of anyone experiencing the same problem. Please help!
Website for reference: www.bigredbutton.tv - click a video to play it and then use the native full screen controls.
Thanks!
