I have a youtube video introduced by <iframe>
tag (I tried by <object>
also, but the results are the same). On the load page, I have a dialog modal also (that it works properly).
I don't understand why, only on IE11.0, this video is not "hidden" (meaning inactive, like all other elements of the site, until the window is closed).
Is it something special, particularly for IE, that I need to add in css? I tried z-index (only idea which I had), with negative values for this video, but it doesn't work. It is a bug of IE? I have no idea... Thanks in advance.
PS. If it is necessary, I can add the css file also (but it's a little big). PS.2. I repeat, for other browsers (Chrome, Firefox, Opera and Safari), this works properly (the video is inactive while the dialog modal is active (not closed).
