I learnt from this post (Making an iframe responsive) that make an iframe responsive by adding a container with a class around the iframe, for instance,
<div class="intrinsic-container">
<iframe width="560" height="315" src="https://www.youtube.com/embed/I4YoBuJCbfo" frameborder="0" allowfullscreen></iframe>
</div>
Is there possible to embed <iframe>...</iframe> directly in my posts (without using <div>...</div>)? And I tried these solutions, but all of them don't work.
PS: I use two columns layout in WordPress. The ratio of video can be 16:9 (from YouTube), 4:3 (from Tencent), etc. Here is a temporary demo.
If you can use viewport units that is doable without an extra wrapper element.
Full page width:
iframe {
width: 100vw;
height: 56.25vw; /*16:9*/
}
<iframe width="560" height="315" src="https://www.youtube.com/embed/I4YoBuJCbfo" frameborder="0" allowfullscreen></iframe>
Half page width:
iframe {
width: 50vw;
height: 28.125vw; /*16:9*/
}
<iframe width="560" height="315" src="https://www.youtube.com/embed/I4YoBuJCbfo" frameborder="0" allowfullscreen></iframe>
The key here is the height and width ratio you want to keep. I took the liberty of using jQuery instead of javascript to do this. The code triggers upon clicking the button. It calculates the width and height ratio of the iframe and adapts both to your needs (in this case I assumed you wanted it to fill the containers width).
You'll probably want to loop through all videos if you have multiple on one page and run the code on window resizing and page-loading.
Here is the JSFiddle
Hope it helps :)
html
<iframe id="iframe" width="640" height="360" src="https://www.youtube.com/embed/4SDVkdcO8ts" frameborder="0" allowfullscreen></iframe>
<button id="button" style="float: left">Click me!</button>
jQuery
$(document).ready(function(){
$("button").click(function(){
var ratio = $("#iframe").height() / $("#iframe").width();
$("#iframe").width("100%");
var newWidth = $("#iframe").width();
$("#iframe").width(newWidth);
$("#iframe").height(newWidth*ratio);
$("button").text("resize the window and click me again!");
});
});
Use bootstrap class to make iframe responsive.
<div class="embed-responsive embed-responsive-16by9">
<iframe class="embed-responsive-item" allowfullscreen
src="//www.youtube.com/embed/zpOULjyy-n8?rel=0" >
</iframe>
</div>

I know that this has been asked many times, but I open this discussion to solve my problem and to summarize all we know about this topic to help people in the future.
So, let's go.
We want to upload a video (e.g. from YouTube). We can do this pasting the video url or using the MediaEmbed button.
We have two possibility.
We can set or not in our editorConfig
mediaEmbed: { previewsInData: true }
WITHOUT previewsInData: true we obtain something like this:
<figure class="media">
<oembed url="https://www.youtube.com/watch?v=something"></oembed>
</figure>
Instead WITH previewsInData: true we obtain something like this
<figure class="media">
<div data-oembed-url="https://www.youtube.com/watch?v=vsl3gBVO2k4&ab_channel=H%C3%A9lderPalma">
<div style="position: relative; padding-bottom: 100%; height: 0; padding-bottom: 56.2493%;">
<iframe src="https://www.youtube.com/embed/vsl3gBVO2k4" style="position: absolute; width: 100%; height: 100%; top: 0; left: 0;" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen="">
</iframe>
</div>
</div>
</figure>
In both cases i'm able to see the preview of the youtube video in my CKEditor.
But when I save the content of the editor and I get that to display it in my presentation page the video is not displayed.
Reading the other discussions here on the forum I couldn't figure out if this is just my problem or not. Many solutions concerning adding previewsInData: true in editorConfig, but for me absolutely nothing changes.
I think that the tag figure and the oembed div is useful to CKEditor to display a preview of the video. We know that this preview is like a picture, you can't play the video, you can't open in a new page, etc. This is ok, but i want to see the video in my presentation page.
So, where is the problem?
Is there something to change on the presentation page to have the video displayed?
Should I search for the figure tag and replace it with an iframe server side?
Any ideas?
I hope we can find a permanent solution to this problem.
You should indeed use a 'frontend' to display the oembed tags, like it says in the manual on : https://ckeditor.com/docs/ckeditor5/latest/features/media-embed.html#displaying-embedded-media-on-your-website
You can provide your own mediaprovider using this :
ClassicEditor
.create( editorElement, {
plugins: [ MediaEmbed, ... ],
mediaEmbed: {
extraProviders: [
{
name: 'extraProvider',
url: /^example\.com\/media\/(\w+)/,
html: match => '...'
},
...
]
}
} )
.then( ... )
.catch( ... );
and the html could be something like :
...
html: match =>
'<div style="position:relative; padding-bottom:100%; height:0">' +
'<iframe src="..." frameborder="0" ' +
'style="position:absolute; width:100%; height:100%; top:0; left:0">' +
'</iframe>' +
'</div>'
you can find more in de docs, here :
https://ckeditor.com/docs/ckeditor5/latest/api/module_media-embed_mediaembed-MediaEmbedProvider.html
you could also do something like this yourself, avoiding external oembed providers:
window.addEventListener('load', function(){
document.querySelectorAll('oembed[url]').forEach( element => {
// get just the code for this youtube video from the url
let vCode = element.attributes.url.value.split('?v=')[1];
// paste some BS5 embed code in place of the Figure tag
element.parentElement.outerHTML= `
<div class="ratio ratio-16x9">
<iframe src="https://www.youtube.com/embed/${vCode}?rel=0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
</div>`;
});
})
You would ofcourse have to upgrade the script for all different versions of embedded content, this example will just work for youtube. You would have to analyze the URL from the oembed tag to check what is embedded so you can add the right code for each variant.
I have an iframe tag and in which I want to show video in full size in any screen like youtube but currently, it shows in small size not fit all area.
My code:
<div class="row">
<iframe oncontextmenu="return false" class="video_container" style="width:90%;height:450px;" src="<?php echo $videoDetail[0]['video_links'];?>?autoplay=1" frameborder="0" allow="autoplay" allowfullscreen></iframe>
</div>
As per image you can see a video not fit in all areas.
I want to wrap an href around a vimeo or youtube video and prevent the default playback click events of the embed and just go to the href. Does anyone know how to do this?
<a href="http://tumblr.com" target="_blank" class="linkwrap">
<iframe width="420" height="315" src="https://www.youtube.com/embed/5Xbs60BMeRU" frameborder="0" allowfullscreen></iframe>
</a>
html
<a href="http://tumblr.com" target="_blank" class="linkwrap">
<div class="blocker"></div>
<iframe width="420" height="315" src="https://www.youtube.com/embed/5Xbs60BMeRU" frameborder="0" allowfullscreen></iframe>
</a>
css
.linkwrap { position:relative; display:inline-block; }
.blocker { position:absolute; height:100%; width:100%; z-index:1; background:rgba(255,0,0,0.5); }
.linkwrap iframe { z-index: 2; }

Use a div as overlay and surround it with your a tag. Read this article to see how to implement the div and using opaque for youtube: https://stackoverflow.com/a/4788044/4375900
I think with this info you should be possible to do what you want to do.
For cross browser support use this:
<div style="position:relative;">
<iframe width="420" height="315" src="https://www.youtube.com/embed/5Xbs60BMeRU" frameborder="0"></iframe>
<img src="https://upload.wikimedia.org/wikipedia/commons/c/ca/1x1.png" width="420px" height="315px">
</div>
I feel like it's worth mentionning that in my case, adding pointer-events: none on the iFrame allowed the link to work with a structure looking like this
<div>
<a href="#test">
<iframe [ATTRIBUTES]></iframe>
</a>
</div>
I've looked at a few implementations of this and so far none have worked so I'm resorting to posting. The concept is: a placeholder image which once clicked changes into the video and autoplays.
Current HTML:
<div id="ytvideo" style="display:none;">
<iframe width="939" height="528" id="ytvideo" frameborder="0" allowfullscreen></iframe>
</div>
<img class="aligncenter size-full" id="homevideo" alt="placeholder" src="/wp-content/uploads/2013/10/placeholder.jpg" width="940" height="548" />
Current JS:
jQuery(document).on('click','#homevideo',function(e){
jQuery('#ytvideo').show();
jQuery('#homevideo').hide();
jQuery('#ytvideo').attr("src","www.youtube.com/embed/[myvidid]?autoplay=1");
jQuery("#ytvideo").attr('src', jQuery("#ytvideo", parent).attr('src') + '?autoplay=1');
});
I've looked at trying to reload the iframe but that doesn't seem to work.
Any ideas?
MARKED: FIXED
You forgot the protocol - www.youtube.com/… would link to folder on the server.
With protocol it works fine – I’d suggest creating the whole iframe dynamically though, because with an empty src attribute at the beginning it would load the same page it is embedded in.
<div id="ytvideo" style="display:none;"></div>
<!-- replaced your image with a span here for fiddle -->
<span id="homevideo" data-vidid="mbOEknbi4gQ">click me</span>
$(document).on('click','#homevideo',function(e){
$('#homevideo').hide();
$('#ytvideo').html('<iframe width="939" height="528" id="ytvideo" frameborder="0" allowfullscreen src="http://www.youtube.com/embed/'+$(this).attr("data-vidid")+'?autoplay=1"></iframe>').show();
});
http://jsfiddle.net/HuVqm/
As discussed in one of the comments, you can get both the img and the video from the api.
This would be good if you didn't want to maintain the image, just wanted it to pull through from YouTube. (However I am not sure that YT provide an image as large as 939 so in your case you might still want to use your own image). I have put in a random channel name 'RIDEChannel' feel free to change that with your channel name.
<div id="vid"></div>
$.getJSON("http://gdata.youtube.com/feeds/api/users/RIDEChannel/uploads?max-results=1&v=2.1&alt=jsonc&callback=?", function (myvid) {
var vid = $("#vid");
$.each(myvid.data.items, function (i, item) {
vid.append("<img width='300' height='250' src='" + item.thumbnail.hqDefault + "'>");
$(document).on("click", "#vid img", function (event) {
vid.append("<iframe width='300' height='250' src='http://www.youtube.com/embed/" + item.id + "?autoplay=1' frameborder='0'></iframe>");
$(this).hide();
});
});
});
So the problem laid with the youtube url missing the http:// prefix and also for the fact that the iframe name was the same as the div it was enclosed in. (How silly of me) Thus it was attaching the SRC to the div, not the iframe.
Working DEMO
Try this,
First you cannot have same id for more than one elements <div id="ytvideo" and <iframe id="ytvideo"
[myvidid] in http://www.youtube.com/embed/[myvidid]?autoplay=1 should be replaced with the id of the video
html
<div id="ytvideo1" style="display:none;">
<iframe width="939" height="528" id="ytvideo" frameborder="0" allowfullscreen></iframe>
</div>
<img class="aligncenter size-full" id="homevideo" alt="placeholder" src="http://thefabweb.com/wp-content/uploads/2012/12/6191814472_fa47c79b67_b-900x600.jpg" width="940" height="548" data-vid='DBNYwxDZ_pA'/>
code
jQuery(document).on('click','#homevideo',function(e){
jQuery('#ytvideo1').show();
jQuery('#homevideo').hide();
jQuery('#ytvideo').attr("src","http://www.youtube.com/embed/"+$(this).data('vid')+"?autoplay=1");
});
If you have more than 1 video, it could be useful to store the url to the video in the html and use a class instead of an id.
Also, if you put the preview image into the background, behind the video, it will stay there until the iframe has loaded, reducing that "flickering" effect when clicked.
I also restructured the markup a bit to reduce redundancy, here I specify the size of the video and the video id only once.
Also, you should use jQuery's .one('click') instead of .click(), since you want that event listener removed after it has fired the first time.
html:
<div class="ytvideo"
data-video="73sgatbknvo"
style="width:939px; height:528px; background-image:url(http://lorempixel.com/939/528/)">
<div class="seo">
Have a meaningful description of the video here
</div>
</div>
CSS:
.ytvideo {
background-position: center;
background-size: contain;
background-repeat: no-repeat;
cursor: pointer;
}
.ytvideo iframe {
border-style: none;
height: 100%;
width: 100%;
}
.ytvideo .seo {
display: none;
}
jQuery:
$('.ytvideo[data-video]').one('click', function() {
$(this).html('<iframe allowfullscreen src="//www.youtube.com/embed/'+$(this).data("video")+'?autoplay=1"></iframe>');
});
If you want to support browsers with no script support, you'd have to add a "noscript" element in the .ytvideo div that already contains the iframe.

i didn't test it, but this could work.
function autoResize(id)
{
var newheight;
newheight=document.getElementById(id).contentWindow.document.body.scrollHeight;
document.getElementById(id).height=newheight + "px";
}
<iframe id="frame1" onload="autoResize('frame1')" ... >
set id for iframe
and in jquery set height
$('#idval').css('height','800px');
