Course in full screen?

Sameeksha, I didn't have time to make a project that toggles this setting and everything, but the code below appears to work okay in IE11, allowing the next button to work ok. Please check it out and test it well. I will put a project together if I get time tomorrow.

var fullStorylinePlayer = document.querySelectorAll("html");
if (fullStorylinePlayer[0].requestFullscreen) {
 fullStorylinePlayer[0].requestFullscreen();
}else if (fullStorylinePlayer[0].mozRequestFullScreen) {
 fullStorylinePlayer[0].mozRequestFullScreen(); // Firefox
}else if (fullStorylinePlayer[0].webkitRequestFullscreen) {
 fullStorylinePlayer[0].webkitRequestFullscreen(); // Chrome and Safari
}else if (fullStorylinePlayer[0].msRequestFullscreen) {
 fullStorylinePlayer[0].msRequestFullscreen(); // IE
}
