I have a webpage that contains an iframe. Inside that iframe is an embedded Youtube video. When I play this video I make it scale up (grow) in size. As the video grows, not all the video is visible because the iframe is not wide enough.
Is it possible to make the iframe 'Overflow its content', ie make the video visible outside the iframe width (please see below screen captures for a clear example of what I am trying to achieve).
This is how the webpage currently looks:
This is how I would like to make the video look when it has fully grown:
Note I just cant make the iframe wider. I've tried giving the iframe (and all its child elements) the CSS overflow: visible but it doesn't change anything.
This is a simple example of how the webpage is arranged:
....head, opening html tag, etc. up here
<body>
<div id="outerContainer" style="overflow: visible">
<div id="navBar">...</div>
<div id="content style="overflow: visible">
<iframe src="myHelpDocumentation.html" style="overflow: visible">
<!-- Inside this iframe/webpage are the embedded Youtube videos.
Each video is an iframe itself (that sits inside a div). -->
</iframe>
</div>
</div>
</body>
Do you know of a way using CSS or HTML to show the video outside the iframe extents? I could potentially use Javascript to remove the video(iframe) from the iframe and place it in the main webpage but this would be very bad website design dont you think?

No, it isn't possible...
The document from iframe is a completely another document, and the browser security will not let you to do this...
Edit: you can use fullscreen property using transparent background color for container and put there your embedded video.
The fullscreen code was described in this answer.

window.open works fine for IE ( as in window.open('iframe.html','','fullscreen=1,channelmode=1'); but I want to find a proper way for IE so that it doesn't reload the contents as I did for the others)
but I found you a better way that works on chrome, safari and FF since they don't support theater mode,
your iframe should be like :
<iframe src="iframe.html" allowFullScreen></iframe>
this is the content page of your iframe:
<html>
<head>
<title></title>
<style type="text/css">
.fullScreen{
width:100%;
height:100%;
}
.minScreen{
width:auto;
height: auto;
}
</style>
<script type="text/javascript" src="jquery-1.10.0.js"></script>
<script type="text/javascript">
$(document).ready(function(){
var element = document.getElementById('container');
var maxed = false;
$('#max').click(function(){
if(maxed){
if (document.mozCancelFullScreen) {
document.mozCancelFullScreen();
element.className = "minScreen";
maxed = false;
} else if (document.webkitCancelFullScreen) {
document.webkitCancelFullScreen();
element.className = "minScreen";
maxed = false;
}
}else{
if (element.mozRequestFullScreen) {
element.mozRequestFullScreen();
element.className = "fullScreen";
maxed = true;
} else if (element.webkitRequestFullScreen) {
element.webkitRequestFullScreen();
element.className = "fullScreen";
maxed = true;
}
}
});
});
</script>
</head>
<body>
<div id="container">
<button id="max">click to maximize/minimize</button>
</div>
</body>
</html>
you can supply that with css to correct the containers height and width, using classes (addClass and removeClass) when maximized or minimized/closed (style added to the code)
IE compatibility function is on the way ..
EDIT: maybe you should look at the problem from another angle if you don't want to use windows or fullscreen.
the solution would be discarding the iframe which is restricting the accessibility and replacing it with a div that has css overflow:hidden and then populate this div with your iframe page's contents (you can use ajax or any other method to load the contents). tada, you have something like an iframe but it is an element of the same document. then, you can control the overflow in two ways:
1- toggle the container's css between overflow:hidden and visible or auto.
2- relocate the element outside the container div and use absolute positioning to show it over other elements.
note: don't be afraid of losing the scroll bar, you can build your own or just link your top css of the contents with the jquery ui slider's value with absolute content's positioning and you are good to go.
