Full screen issu

* {

Padding: 0px

Margin: 0px

}

Body div.videobox {

Width: 400px

Height: 320px

Margin: 100px auto

Background-color:#000

}

Body div.videobox video.video

{

Width: 100%

Height: 100%

}

:-webkit-full-screen {

}

:-moz-full-screen {

}

:-ms-fullscreen {

}

:-o-fullscreen {

}

: full-screen {

}

: fullscreen {

}

:-webkit-full-screen video {

Width: 100%

Height: 100%

}

:-moz-full-screen video {

Width: 100%

Height: 100%

}
