I'd like to make a simple frame my frame slide show with CSS3.
I'd like to define how many times it's goes through each frame. EG; Frame 3 / Last frame it just stops.
I'm finding ALOT of great CSS3 animation demos online; but not many about frame by frame slideshows.
EG: I Like this; http://mos.netmagazine.com/site/files/tutorials/assets/2011/08/animation_01.html -- Though different in terms of animation - But I feel I can use #keyframes; Problem is - I'm trying it here vvv
http://www.w3schools.com/css3/tryit.asp?filename=trycss3_animation1
This functionality is exactly what I want; except it wont let me replace the background: with an image? How could I do this; and last piece of the puzzle -- how can I set a parameter for it to stop at a certain frame?
Final Note - This is for a iPad Website.
You can easily do with javascript or jquery but you cannot do it with CSS3. You can do like this:
#images { width: height: }
#images img { width: height: opacity=0; transition all 5s linear; -moz-transition all 5s linear; -o-transition all 5s linear; -webkit-transition all 5s linear; }
#images img:target { opacity=1; }
<div id="images"> <img src="pic1" id="pic1"/> <img src="pic2" id="pic2"> <img src="pic3" id="pic3"/> . . . <img src="picn" id="picn"/> </div>
<div id="list"> 1 2 3 . . . n </div>

I have embedded HTML5 video with mp4 format. How to get thumbnail image like poster without using "poster" attribute. This problem coming on Safari and iOS. I have added video like below mentioned code.
<video height=350 id='TestVideo' webkit-playsinline><source src='test.mp4' type=video/mp4></video>
On Chrome, IE, Firefox first frame of video coming as thumbnail image, but not coming on Safari and iOS.
simply add preload="metadata" in video tag and set #t=0.1 at url src, it will get the frame of 0.1s of your video as thumbnail
however, the disadvantage of this solution is when you click to play the video, it always start at 0.1s
<video preload="metadata" controls>
<source src="video.mp4#t=0.1" type="video/mp4">
</video>
If you want to do this without storing server side images it is possible, though a bit clunky... uses a canvas to record the first frame of the video and then overlay that over the video element. It may be possible to use the URL for the Canvas as a source for the Poster (eg video.poster = c.toDataURL();) but that requires correct CORS setup (not sure if the video was on your own server, and if you have control over that, so took the safest option). This will work best if video is correctly encoded for streaming (so MOOV atom is at the front of the video, otherwise it will be slow to draw the overlay - see this answer for more detail)
The HEAD contains styling for the video and the overlay (you will need to adjust sizing and position to suit your application)
<head>
<style>
video_box{
float:left;
}
#video_overlays {
position:absolute;
float:left;
width:640px;
min-height:264px;
background-color: #000000;
z-index:300000;
}
</style>
</head>
In the BODY you will need the div for the overlay and the video. The overlay div has an onclick handler to hide the overlay and start the video playing
<div id="video_box">
<div id="video_overlays" onclick="this.style.display='none';document.getElementById('video').play()"></div>
<video id="video" controls width="640" height="264">
<source src="BigBuck.mp4" type='video/mp4'>
</video>
</div>
</div>
Finally you will need code that will load the video, seek to the first frame and load the visual into a canvas that you then insert into the overlay
<script>
function generateOverlay() {
video.removeEventListener('seeked',generateOverlay); / tidy up the event handler so it doesn't redraw the overlay every time the user manually seeks the video
var c = document.createElement("canvas");
var ctx = c.getContext("2d");
c.width = 640;
c.height = 264;
ctx.drawImage(video, 0, 0, 640, 264); // take the content of the video frame and place in canvas
overlay.appendChild(c); // insert canvas into the overlay div
}
// identify the video and the overlay
var video = document.getElementById("video");
var overlay = document.getElementById("video_overlays");
// add a handler that when the metadata for the video is loaded it then seeks to the first frame
video.addEventListener('loadeddata', function() {
this.currentTime = 0;
}, false);
// add a handler that when correctly seeked, it generated the overlay
video.addEventListener('seeked', function() {
// now video has seeked and current frames will show
// at the time as we expect
generateOverlay();
}, false);
// load the video, which will trigger the event handlers in turn
video.load();
</script>
this is a bit late but we had the same scenario. I can't use the attribute 'muted' because my videos are podcasts. This is what I came up with and I hope to share it with future visitors. What I did is load the video in the body tag, drew a canvas, retrieved as base64 and applied to the video as the background image.
Since my video should be fixed 150px in height, I computed the aspect ratio so that whatever height and width of the actual video, it will be resized into 150px height and dynamic width.
$('body').append('<video class="checkmeload" style="position:absolute;top:-10000px" controls preload="auto" playsinline src="//src-here"><source src="//src-here" type="//videotype-here"></video>');
$('body').find('.checkmeload').on('loadeddata', function(){
var video = $('.checkmeload');
var canvas = document.createElement('canvas');
aspectratio = (video[0].videoWidth / video[0].videoHeight);
newwidth = (150 * aspectratio);
canvas.width = newwidth;
canvas.height = 150;
var context = canvas.getContext('2d');
context.drawImage(video[0], 0, 0, canvas.width, canvas.height);
var dataURI = canvas.toDataURL('image/jpeg');
$('body').find('.checkmeload').remove();
$('#myvideo').css('background-image','url("'+dataURI +'")');
});
Source: How to set the thumbnail image on HTML5 video?
This worked for me:
<img src="thumbnail.png" alt="thumbnail" />
/* code for the video goes here */
Now using jQuery play the video and hide the image as
$("img").on("click", function() {
$(this).hide();
// play the video now..
})
Add #t=0.001 at the end of the video URL.

I have a HTML5 canvas that I'm trying to draw clouds on. It works fine when running in Chrome when testing in Ripple, and when running in the emulator, but fails when running on actual device (10" Samsung Galaxy Tab).
For testing purposes I commented out almost all code and just drew a colored rectangle on the entire canvas so I could see the borders of the canvas. I want to see one yellow rectangle near the upper-left corner of the screen with a bit of whitespace on the left (comes out to about 15px) and some whitespace below the header (total distance from the top of the rectangle to the top of the window is 42px). Call the upper left corner of the rectangle at position (15,42).
However, the tablet draws the rectangle but also draws a copy of itself starting at the very upper left corner of the screen -- position (0,0). The 'correct' rectangle overlaps and appears on top of the 'bad' rectangle.
Here's an image of what I want it to look like.
Here's the HTML:
<div data-role="page" id="makeClouds">
<div data-role="header">
Menu
<h1>Make clouds</h1>
Journal
</div>
<div data-role="content">
<div id="coverageButtons">
Less clouds
More clouds
<p id="cloudCoverageDisplay"></p>
</div>
<div id="canvasDiv">
<canvas id="canvasClouds">Sorry, your browser is not supported.</canvas>
</div>
</div>
</div>
Here's the javascript:
$(document).delegate("#makeClouds", "pageshow", function() {
console.log("Loading page makeClouds.");
//drawClouds();
var canvas = document.getElementById('canvasClouds');
var context = canvas.getContext('2d');
context.beginPath();
context.rect(0, 0, canvas.width, canvas.height);
context.fillStyle = 'yellow';
context.fill();
context.lineWidth = 7;
context.strokeStyle = 'black';
context.stroke();
});
And here's the CSS:
#canvasDiv {
z-index: 2;
}
#canvasClouds {
background-color: blue;
z-index: 20;
}
I'm at a loss here, any help would be greatly appreciated.
Had to set 'position: absolute' on the canvas (which is inside the div) and this fixed the issue.
Fixed from details in link from #AnupChaudhari.

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;
}
Is there a way to modify the Twitter 'follow' button to display the number of followers in a bubble but hide the word "followers"? I basically want my 'follow' button to look the same as the 'tweet' button.
The current code looks like this:
<a href="https://twitter.com/User" class="twitter-follow-button" data-show-count="true"
data-show-screen-name="false" data-dnt="true">Follow #User</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id))
{js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";
fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
I had this same issue and solved it by basically hiding the word 'followers' and creating a fake right edge to the bubble, if that makes sense. So, you have to wrap the button in its own div, then hide the overflow of that div and set the width to the exact point where the word disappears and the height precisely to the height of the button you are using. Here's a code example:
#titter-div {
border-radius: 4px; /* to mimic the curved edges of the count box */
border-right: 1px solid #AAAAAA; /* this is the width and color of the count box border */
height: 20px; /* this height works for the medium button */
width: 88px; /* precise width to hide the word */
overflow: hidden; /* actually hides the word */
}
This worked for me to create exactly what you are looking for. Hope this helps.
To display the number of followers in a bubble but hide the word "followers", here is the code I use with an iframe :
<iframe
src="//platform.twitter.com/widgets/follow_button.html?screen_name=Vacance_Luberon&show_screen_name=false"
style="width: 88px; height: 20px;"
allowtransparency="true"
frameborder="0"
scrolling="no">
</iframe>
Can you superimpose canvas over video in IOS safari (IPAD)?
I tried adding text to the canvas but it does not show up on top of the video playing.
ON SAfari desktop it just works fine.
video_dom.addEventListener('play', function() {
ctx_overlay.font = "bold 16px sans-serif";
ctx_overlay.fillStyle="black";
ctx_overlay.fillText("Video1 Video1 Video1", 200, 225);
}, false);
<video id="video-canvas-fancy" loop autoplay loop height="640" width="965" style="position:absolute; top: 5; left: 5;">
<source src="http://severe-fire-901.heroku.com/videos/home.m3u8">
</video>
<canvas id="canvas-overlay" height="640" width="965" style="position:absolute; top: 10; left: 10;">
</canvas>
Please give more details or a code example in the future.
You mean <video>? With absolute positioning you should be able to put anything over it.
If you can't for some (buggy) reason on IOS, you can always use a <canvas> to render the video (call context.drawImage(video,0,0) every x frames per second) and then either render stuff on top of that or on top of a second canvas.
