I have a YouTube video embedded on our website and when I shrink the screen to tablet or phone sizes it stops shrinking at around 560px in width. Is this standard for YouTube videos or is there something that I can add to the code to make it go smaller?
You can make YouTube videos responsive with CSS. Wrap the iframe in a div with the class of "videowrapper" and apply the following styles:
.videowrapper {
float: none;
clear: both;
width: 100%;
position: relative;
padding-bottom: 56.25%;
padding-top: 25px;
height: 0;
}
.videowrapper iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
The .videowrapper div should be inside a responsive element. The padding on the .videowrapper is necessary to keep the video from collapsing. You may have to tweak the numbers depending upon your layout.
If you are using Bootstrap you can also use a responsive embed. This will fully automate making the video(s) responsive.
http://getbootstrap.com/components/#responsive-embed
There's some example code below.
<!-- 16:9 aspect ratio -->
<div class="embed-responsive embed-responsive-16by9">
<iframe class="embed-responsive-item" src="..."></iframe>
</div>
<!-- 4:3 aspect ratio -->
<div class="embed-responsive embed-responsive-4by3">
<iframe class="embed-responsive-item" src="..."></iframe>
</div>
Refined Javascript only solution for YouTube and Vimeo using jQuery.
// -- After the document is ready
$(function() {
// Find all YouTube and Vimeo videos
var $allVideos = $("iframe[src*='www.youtube.com'], iframe[src*='player.vimeo.com']");
// Figure out and save aspect ratio for each video
$allVideos.each(function() {
$(this)
.data('aspectRatio', this.height / this.width)
// and remove the hard coded width/height
.removeAttr('height')
.removeAttr('width');
});
// When the window is resized
$(window).resize(function() {
// Resize all videos according to their own aspect ratio
$allVideos.each(function() {
var $el = $(this);
// Get parent width of this video
var newWidth = $el.parent().width();
$el
.width(newWidth)
.height(newWidth * $el.data('aspectRatio'));
});
// Kick off one resize to fix all videos on page load
}).resize();
});
Simple to use with only embed:
<iframe width="16" height="9" src="https://www.youtube.com/embed/wH7k5CFp4hI" frameborder="0" allowfullscreen></iframe>
Or with responsive style framework like Bootstrap.
<div class="row">
<div class="col-sm-6">
Stroke Awareness
<div class="col-sm-6>
<iframe width="16" height="9" src="https://www.youtube.com/embed/wH7k5CFp4hI" frameborder="0" allowfullscreen></iframe>
</div>
</div>
Relies on width and height of iframe to preserve aspect ratio
Can use aspect ratio for width and height (width="16" height="9")
Waits until document is ready before resizing
Uses jQuery substring *= selector instead of start of string ^=
Gets reference width from video iframe parent instead of predefined element
Javascript solution
No CSS
No wrapper needed
Thanks to #Dampas for starting point.

I used the CSS in the accepted answer here for my responsive YouTube videos - worked great right up until YouTube updated their system around the start of August 2015. The videos on YouTube are the same dimensions but for whatever reason the CSS in the accepted answer now letterboxes all our videos. Black bands across top and bottom.
I've tickered around with the sizes and settled on getting rid of the top padding and changing the bottom padding to 56.45%. Seems to look good.
.videowrapper {
position: relative;
padding-bottom: 56.45%;
height: 0;
}
#magi182's solution is solid, but it lacks the ability to set a maximum width. I think a maximum width of 640px is necessary because otherwhise the youtube thumbnail looks pixelated.
My solution with two wrappers works like a charm for me:
.videoWrapperOuter {
max-width:640px;
margin-left:auto;
margin-right:auto;
}
.videoWrapperInner {
float: none;
clear: both;
width: 100%;
position: relative;
padding-bottom: 50%;
padding-top: 25px;
height: 0;
}
.videoWrapperInner iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
<div class="videoWrapperOuter">
<div class="videoWrapperInner">
<iframe src="//www.youtube.com/embed/C6-TWRn0k4I"
frameborder="0" allowfullscreen></iframe>
</div>
</div>
I also set the padding-bottom in the inner wrapper to 50 %, because with #magi182's 56 %, a black bar on top and bottom appeared.
Modern simple css solution
The new aspect-ratio is the modern solution to this problem.
aspect-ratio: 16 / 9;
That's all you need to make a div, image, iframe size automatically. Samples.
It's got good support, but is not yet in Safari (will be for upcoming iOS15) - so for now you'll still need to use a fallback. You can achieve that with the #supports feature
.element
{
aspect-ratio: 16 / 9;
#supports not (aspect-ratio: 16 / 9)
{
// take your pick from the other solutions on this page
}
}
Assuming your development browser does support this property be sure to test without it by commenting out both aspect-ratio and #supports.
This is old thread, but I have find new answer on https://css-tricks.com/NetMag/FluidWidthVideo/Article-FluidWidthVideo.php
The problem with previous solution is that you need to have special div around video code, which is not suitable for most uses. So here is JavaScript solution without special div.
// Find all YouTube videos - RESIZE YOUTUBE VIDEOS!!!
var $allVideos = $("iframe[src^='https://www.youtube.com']"),
// The element that is fluid width
$fluidEl = $("body");
// Figure out and save aspect ratio for each video
$allVideos.each(function() {
$(this)
.data('aspectRatio', this.height / this.width)
// and remove the hard coded width/height
.removeAttr('height')
.removeAttr('width');
});
// When the window is resized
$(window).resize(function() {
var newWidth = $fluidEl.width();
// Resize all videos according to their own aspect ratio
$allVideos.each(function() {
var $el = $(this);
$el
.width(newWidth)
.height(newWidth * $el.data('aspectRatio'));
});
// Kick off one resize to fix all videos on page load
}).resize();
// END RESIZE VIDEOS
If you are using Bootstrap 5.0, you can use .ratio
https://getbootstrap.com/docs/5.0/helpers/ratio/
Example
<div class="ratio ratio-16x9">
<iframe src="https://www.youtube.com/embed/zpOULjyy-n8?rel=0" title="YouTube video" allowfullscreen></iframe>
</div>
With credits to previous answer https://stackoverflow.com/a/36549068/7149454
Boostrap compatible, adust your container width (300px in this example) and you're good to go:
<div class="embed-responsive embed-responsive-16by9" style="height: 100 %; width: 300px; ">
<iframe class="embed-responsive-item" src="https://www.youtube.com/embed/LbLB0K-mXMU?start=1841" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="" frameborder="0"></iframe>
</div>
Okay, looks like big solutions.
Why not to add width: 100%; directly in your iframe. ;)
So your code would looks something like <iframe style="width: 100%;" ...></iframe>
Try this it'll work as it worked in my case.
Enjoy! :)
I make this with simple css as follows
HTML CODE
<iframe id="vid" src="https://www.youtube.com/embed/RuD7Se9jMag" frameborder="0" allowfullscreen></iframe>
CSS CODE
<style type="text/css">
#vid {
max-width: 100%;
height: auto;
}

I can only find questions where people have the opposite problem.
I want my fixed content to go above the iOS keyboard.
Image of the problem:
I want iOS to behave like Android.
Is there a simple way to achieve this?
Parent element css:
.parent{
position:fixed;
top: 0;
left 0;
right: 0;
bottom: 0;
width: 100%;
height: 100%;
}
Button css:
.button{
position:fixed;
left 0;
right: 0;
bottom: 0;
width: 100%;
height: 5rem;
}
We can use VisualViewport to calculate keyboard height. So we can set fixed-content pos correct.
Small demo: https://whatwg6.github.io/pos-above-keyboard/index.html
Code snippet:
const button = document.getElementById("button");
const input = document.getElementById("input");
const height = window.visualViewport.height;
const viewport = window.visualViewport;
window.addEventListener("scroll", () => input.blur());
window.visualViewport.addEventListener("resize", resizeHandler);
function resizeHandler() {
if (!/iPhone|iPad|iPod/.test(window.navigator.userAgent)) {
height = viewport.height;
}
button.style.bottom = `${height - viewport.height + 10}px`;
}
function blurHandler() {
button.style.bottom = "10px";
}
html,
body {
margin: 0;
padding: 0;
}
#button {
position: fixed;
width: 100%;
bottom: 10px;
background-color: rebeccapurple;
line-height: 40px;
text-align: center;
}
<input type="text" inputmode="decimal" value="0.99" id="input" onblur="blurHandler()" />
<div id="button">Button</div>

Why not innerHeight?: Iphone safari not resizing viewport on keyboard open
Mobile Safari does not support position: fixed when an input focused and virtual keyboard displayed.
To force it work the same way as Mobile Chrome, you have to use position: absolute, height: 100% for the whole page or a container for your pseudo-fixed elements, intercept scroll, touchend, focus, and blur events.
The trick is to put the tapped input control to the bottom of screen before it activates focus. In that case iOS Safari always scrolls viewport predictably and window.innerHeight becomes exactly visible height.
Open https://avesus.github.io/docs/ios-keep-fixed-on-input-focus.html in Mobile Safari to see how it works.
Please avoid forms where you have several focusable elements because more tricks to fix position will be necessary, those were added just for demonstration purposes.
Note that for rotation and landscape mode, additional tricks are necessary. I'm working on a framework called Tuff.js which will provide a full-screen container helping mobile web developers to build web applications much faster. I've spend almost a year on the research.
By the way, to prevent scrolling of the whole window when virtual keyboard is active, you can use this super simple trick
var hack = document.getElementById('scroll-hack');
function addScrollPixel() {
if (hack.scrollTop === 0) {
// element is at the top of its scroll position, so scroll 1 pixel down
hack.scrollTop = 1;
}
if (hack.scrollHeight - hack.scrollTop === hack.clientHeight) {
// element is at the bottom of its scroll position, so scroll 1 pixel up
hack.scrollTop -= 1;
}
}
if (window.addEventListener) {
// Avoid just launching a function on every scroll event as it could affect performance.
// You should add a "debounce" to limit how many times the function is fired
hack.addEventListener('scroll', addScrollPixel, true);
} else if (window.attachEvent) {
hack.attachEvent('scroll', addScrollPixel);
}
body {
margin: 0 auto;
padding: 10px;

}

<h1>iOS Scroll Hack</h1>
<p>Elements with overflow:scroll have a slightly irritating behaviour on iOS, where when the contents of the element are scrolled to the top or bottom and another scroll is attempted, the browser window is scrolled instead. I hacked up a fix using minimal,
native JavaScript.</p>
<p>Both lists have standard scrolling CSS applied (<code>overflow: auto; -webkit-overflow-scrolling: touch;</code>), but the list on the right has the hack applied. You'll notice you can't trigger the browser to scroll whilst attempting to scroll the list
on the right.</p>
<p>The only very slight drawback to this is the slight "jump" that occurs when at the top or bottom of the list in the hack.</p>

Got this answer from here
This is a well known problem, and unfortunately one must resort to hacky tricks like the accepted answer for now. The W3C is however in the process of specifying The VirtualKeyboard API.
Note: At the time of writing, this answer is not yet ready for prime time. It's important to understand that this specification must also be forward looking, to adapt to the myriad possible virtual keyboards of the future. It may be a few years before reliable cross platform browser support begins to appear and this answer becomes the correct one.
I found an interesting solution to this problem.
The solution is to create a hidden input and focus on it on the touchstart event.
<input id="backinput" style="position:absolute;top:0;opacity:0;pointer-events: none;">
<input id="input" style="position:absolute;bottom:0;">
Using JQuery:
$('#backinput').on('focus',function(e)
{
e.preventDefault();
e.stopPropagation();
const input = document.getElementById('input');
input.focus({ preventScroll: true });
})
$('#input').on("touchstart", function (event) {
if(!$(this).is(":focus"))
{
event.stopPropagation();
event.preventDefault();
$('#backinput').focus();
}
})
Finally, resize the viewport so that the bottom input moves above the keyboard (if needed)
window.visualViewport.addEventListener("resize", (event) => {
$('body').height(parseInt(visualViewport.height));
});
For me it works perfect. I am building a messenger.
I have really bad situation. I have my custom div which I m showing under page. The only issue I have at moment that it's not working on iPad. The overlay covers the popup even after I have proper z-index to both element.
This issue only facing with iPad safari. On other browser it's working fine. I found one solution where I need to shift my popup next to or near by overlay div which is not possible for me due to binding context of knockout.js
The issue snap
here as you can see the attached image the opened calender is behind the overlay gray div.
Below is the html structure where the higlited is the calender container & at last overlay div.
Let me know if some can suggest me some good idea to deal with this.
It seems like if your fixed element is inside an other fixed element that has lower z-index than overlay it will stay behind it even if the element itself has a higher z-index. So you have to find that higher fixed element and change it's z-index to something higher.
.overlay {
position: fixed;
top: 0;
left: 0;
right: 0;
bottom: 0;
background: rgba(0, 0, 0, 0.5);
z-index: 4;
}
.lower {
position: fixed;
z-index: 2
}
.popup {
position: fixed;
border: 1px solid black;
background: white;
height: 200px;
width: 200px;
z-index: 100;
}
<div class="lower">
<div class="popup"></div>
</div>
<div class="overlay"></div>
It's also happen for me in Safari, simply I solve it by remove overflow:hidden from parent div.
I have an iFrame generated by ThingLink that I need to drop into an existing web page and behave responsively.
I would have thought that the usual CSS used to make YouTube or Vimeo iFrames would do the job. Which it does on most browsers, but for whatever reason this does not seem to be the case for Safari on IOS (Safari desktop appears to work). Why is this? Is there something in the Iframe's HTML that is causing an issue?
Here's a Fiddle showing the iFrame in question misbehaving (top) and a sample YouTube iFrame behaving (bottom).
And of course the actual code I am using
HTML:
CSS:
div.iwrap {
width: 100% ;
position: relative;
padding-bottom: 60%;
height: 0;
-webkit-overflow-scrolling:touch;
overflow: hidden;
}
.iwrap object,
.iwrap iframe,
.iwrap embed {
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
width: 100% !important;
height: 100% !important;
border: none;
}
iframe,
object,
embed {
max-width: 100%;
}
You can see I've tried trying out the absolutely positioning each corner of the iframe, but with no joy.
I should stress that it is only Safari on IOS that it breaks. Safari for desktop and Android for mobile look good.
Any pointers to get that working would be much appreciated, but more importantly, why isn't it.
Using responsive iframe code I devised for myself, and using your src= url, I created and tested this Pen on CodePen.
Using CodePen's CrossBrowser Testing, the Pen displays and functions correctly on Android mobile devices. (With one exception: the embedded Youtube video has no audio in CrossBrowser Testing although in normal view it does.) But on iOS devices it displays only a black square where the content should be.
I'm not certain from your post whether this is the failure you are talking about.
I have other Pens, e.g., Responsive Iframe - Base Code, which function correctly on iOS devices. Just the one using your src= url does not.
This leads me to wonder whether, even though using known responsive HTML and CSS, there is something about the source that's not playing nicely with iOS.
I'm not sufficiently versed in the technology to be able to suggest what that might be, however, I hope I've demonstrated that even with code known to be responsive the source document doesn't display in iOS. Thus, the problem appears not to be with the code but rather some conflict inherent between the source and iOS.
Sorry I couldn't be of more help, but maybe this will help you to rephrase the question and question title more narrowly and specifically so that it will grab another user's attention.
The editor insists that, with a link to CodePen, I must include some code. So, merely to satisfy that requirement, here is my responsive HTML and CSS code.
HTML:
<div id="Iframe-Thinglink"

Okay, so I was styling a blurred header for my company and one of our QA ran into a strange issue. Basically illustrated below.
HTML:
<!-- HTML FILE -->
<div class="bg-item"></div>
CSS:
/* Stylesheet */
.bg-item {
width: 200px;
height: 200px;
display: block;
filter: blur(40px);
background: url('../img/bg.jpg') 0 0 / cover no-repeat;
}
It works on all devices and browsers, except when I set Safari to be in 3x iPhone 6 Plus size (hehe) - then the css style shows that it is invalid...
Verified it on an actual iPhone 6 Plus as well and this holds true? Is it an Apple bug or am I doing something wrong?
Actually it IS a bug on Apple's end, at least it would appear that way considering they didn't openly declare they've dropped support for CSS Filters.
You can use their new backdrop filter to work around this though pretty easily, I've demo'd it below.
HTML:
<!-- HTML FILE -->
<div class="img-wrap">
<div class="bg-overlay"></div>
<div class="bg-item"></div>
</div>
CSS:
/* Stylesheet */
.img-wrap {
width: 200px;
height: 200px;
display: block;
}
.bg-overlay {
width: 100%;
height: 100%;
}
.bg-img {
width: 100%;
height: 100%;
filter: blur(60px);
background: url('../img/bg.jpg') 0 0 / cover no-repeat;
}
//Only show on 3x density devices
#media only screen and (-webkit-min-device-pixel-ratio: 3) {
.ios.bg-overlay {
-webkit-backdrop-filter: blur(60px); //Blurs bg behind it
}
}
In a nutshell, just set up a media query to only use the backdrop on 3x ratio devices on webkit - and as much as I hate to say it android chrome will NOT know what to do with this so you will want to make sure this only gets applied to SAFARI, IOS devices - and it should take care of it.
Hope that helps!
I've implemented a simple left-pull burger menu in a mobile webpage that lives inside an iframe. However, it's behaving strangely on iPhones. We are using Bootstrap for the general page layout and stuff.
Using WeInRe I've noticed the following behaviour: in an iframe with 320px in fixed width, if I add, say, left: 50px to the body of the page inside it, this body moves 50px to the left just fine, but also starts to display 370px in width, instead of 320px as before.
The problem is worse: as the correct left value is a percentage, the body gets that bigger width, and after that the left is recalculated, making the menu larger than the viewport.
What the hell is happening here? Is this some sort of known bug of Mobile Safari?
Unfortunately, there's no public available code for this issue yet...
This is the relevant code:
.offcanvas {
left: 0;
position: relative;
}
.offcanvas.active {
left: 75%;
overflow: hidden;
}
.sidebar {
position: fixed;
background-color: #5c008a;
top: 0;
left: -75%;
width: 75%;
height: 100%;
}
.offcanvas.active .sidebar {
left: 0;
}
$('[data-toggle="offcanvas"]').click(function() {
$('.offcanvas').toggleClass('active');
});
<body class="offcanvas">
[...]
<div class="sidebar">[...]</div>
[...]
</body>
Here's a sample, based on a series of side menus from a tutorial (click the left or right push options).
