I'm trying to make an image gallery that's navigated by dragging horizontally. The issue I'm currently facing is that there are no boundaries on the left and right for when the elements should stop dragging. I've tried using the 'container' element, but when I do, it stops dragging altogether.
I've tried using 'parent' or the actual div as the container and neither has worked properly. I saw on another message board that using flexbox in this situation makes things more complicated, so I switched to using display: inline-block on images.
This is my current draft: https://jsfiddle.net/samseurynck/ka1e9soj/21/
HTML
<div class="item_block_left">
<div class="item_block_left_gallery_container">
<div class="item_block_left_gallery">
<img class="item_block_left_gallery_item" src="https://placeimg.com/640/480/animals">
<img class="item_block_left_gallery_item" src="https://placeimg.com/200/200/animals">
<img class="item_block_left_gallery_item" src="https://placeimg.com/640/400/animals">
</div>

</div>
SCSS
.item_block_left{
height:200px;
width: 50%;
border: 1px solid pink;
overflow: hidden;
.item_block_left_gallery_container{
position: relative;
height:100%;
width: auto;
.item_block_left_gallery{
height:100%;
display: flex;
cursor: grab;
.item_block_left_gallery_item{
position: relative;
height:100%;
width:auto;
display: inline-block;
}
}
}
}
JQUERY
$(".item_block_left_gallery").draggable({
scroll: false,
axis: "x",
});
The intended result is only being able to scroll/drag horizontally as far as the images go, with no white space on the left or right sides.
Working Example: https://jsfiddle.net/Twisty/4ak6q0zu/44/
JavaScript
$(function() {
var bounds = {
left: $(".item_block_left_gallery").position().left
};
bounds.right = bounds.left - $(".item_block_left_gallery").width() - $(".item_block_left").width() + 10;
$(".item_block_left_gallery").draggable({
scroll: false,
axis: "x",
drag: function(e, ui) {
var l = ui.position.left;
if (l > bounds.left) {
console.log("Hit Left Boundry");
ui.position.left = bounds.left;
}
if (l <= bounds.right) {
console.log("Hit Right Boundry");
ui.position.left = bounds.right;
}
}
});
});
Using drag callback, you can check and set the position of the draggable item. Basing things off the left edge of the drag item, we can check and restrict the movement based on some specific boundaries. It appears that there was a 10px padding or margin on the right hand side, might just be white space, so I just adjusted to correct for this.

Hope that helps.

When SVG image is clicked, alert function does not trigger in IPhone. (It works in android).
How can I make this workin IPhone without using z-index and overlay div?
HTML
<div id="svg" style="position: relative; background: green; width: 900px; height: 900px;" >
<object id="object" type="image/svg+xml" data="http://www.useragentman.com/tests/pointerEvents/images/tv-path.svg">
</object>
</div>
CSS
#svg object{
pointer-events: none;

Javascript
$('#svg').on('click', function () {
alert('hello');
});
I have a standard website, and when printed (for PDF-making purposes on Safari OS X), I'd like the footer to align to the bottom of whatever printed page it is on — i.e. the last page of the document.
Like this:
Is that possible?
I have used a media query (#media print { }) for all other print stylesheet details (excluded for simplicity).
Demo code is here; for the screen page itself, here is the HTML:
<div id="footer">
<p>A bunch of example stuff inside here...</p>
</div>
Which is situated with absolute positioning:
#footer {
color: #fff;
background: #000;
width: 100%;
position: absolute;
bottom: 0px;
}
Bit of an old one but the answer is surely to use the #page:last selector, but you have to alter the CSS for the footer as well.
#footer { position: static; }
#page:last {
#bottom-center { content:element(footer) }
}
I have a YouTube video I want to put on my web page.
I want to scale the video to fit to a percent of the users browser but also to keep the aspect ratio.
I have tried this:
<iframe width="87%" height="315" src="http://www.youtube-nocookie.com/embed/dU6OLsnmz7o" frameborder="0" allowfullscreen></iframe>
But that does only make the player wider, not higher.
Does I have to resort to JavaScript (or non-standard CSS)?
What i believe to be the best CSS solution.
.auto-resizable-iframe {
max-width: 420px;
margin: 0px auto;

I hit a similar issue with my site when developing some responsive CSS. I wanted any embedded Youtube objects to resize, with aspect, when switching from the desktop CSS to something smaller (I use media queries to re-render content for mobile devices).
The solution I settled on was CSS and mark-up based. Basically, I have three video classes in my CSS thus:
.video640 {width: 640px; height: 385px}
.video560 {width: 560px; height: 340px}
.video480 {width: 480px; height: 385px}
… and I assign one of these to the Youtube content I include, depending on its original size (you may need more classes, I just picked the most common sizes).
In the media query CSS for smaller devices, these same classes are simply re-stated like so:
.video640 {width: 230px; height: 197px}
.video560 {width: 230px; height: 170px}
.video480 {width: 240px; height: 193px}
I appreciate this requires some mark-up "up-front" when including videos in your HTML (i.e. adding a class), but if you don't want to go down the Javascript route, this works pretty well -- you could re-state your video classes for as many different sizes as you require. Here's how the Youtube mark-up looks:
<object class="video640" type="application/x-shockwave-flash" value="YOUTUBE URL">
<param name="movie" value="YOUTUBE URL"></param>
</object>
Quite easy with some javascript.
jQuery(function() {
function setAspectRatio() {
jQuery('iframe').each(function() {
jQuery(this).css('height', jQuery(this).width() * 9/16);
});
}
setAspectRatio();
jQuery(window).resize(setAspectRatio);
});
This jQuery plugin has been making the rounds of late, it's called FitVids and does exactly what you need, resizes videos based on browser size whilst maintaining aspect ratio.

Modern Solution (2022) - aspect-ratio
With the introduction of the aspect-ratio property in CSS, it's now very simple to scale a YouTube video without resorting to CSS hacks or JS.
Example:
iframe {
aspect-ratio: 16 / 9;
height: auto;
width: 100%;
}
The aspect-ratio property is widely supported across browsers making it suitable for the vast majority of sites: https://caniuse.com/mdn-css_properties_aspect-ratio
These work a treat no JS. Responsive for both single palyer and list player modified from somewhere not sure, no credit sorry. Load your iframe Youtube player inside a container div, the iframe style sets the player specific sizing, 100% will fill the container to any size, src= your-youtube-ID, add own player options
https://jsfiddle.net/jcb01/04sf3byz/
<div style=" position: relative; padding-bottom: 56.25%;">
<!--- load iframe Youtube player inside this div -->
<iframe
style="border: 1; top: 0; left: 0; width: 100%; height: 100%; position: absolute;"
src="https://www.youtube-nocookie.com/embed/?
list=PL590L5WQmH8fmto8QIHxA9oU7PLVa3ntk;
&autoplay=0&enablejsapi=1&index=0&
listType=playlist&loop=1&modestbranding=1"
allowfullscreen scrolling="no"
allow="encrypted-media; accelerometer;
gyroscope; picture-in-picture">
</iframe>
</div>
The trick to make a youtube video autoresize is to make the iframe width 100% and put it in a div with a "padding-bottom" equal to the aspect ratio in percentage. E.g.
But the problem is - you would have a lot of pages with embedded YoutTube videos already. Here's a jquery plugin that will scan all videos on the page and make them resizable automatically by changing the iframe code to be as above. That means you don't have to change any code. Include the javascript and all your YouTube videos become autoresizing.

Old question, but I think the #media CSS 3 tags would be helpful in this instance.
Here is my solution to a similar problem.
The CSS:
#media only screen and (min-width: 769px) {
.yVid {
width: 640px;
height: 360px;
margin: 0 auto;
}
}
#media only screen and (max-width: 768px) {
.yVid {
width: 560px;
height: 315px;
margin: 0 auto;
}
}
The HTML:
<div class="yVid">
<iframe width="100%" height="100%" frameborder="0" allowfullscreen="" src="http://www.youtube.com/embed/_OBlgSz8sSM"></iframe>
</div>
This basically adds a breakpoint at 768px where the video resizes itself. You could also add breakpoints at 992 and 1280 for an even more repsonsive video size. (numbers based on Bootstrap standard sizes).
This is what worked for me. This is slightly modified code from the YouTube Embed Code Generator.
The CSS:
.video-container {
position: relative;
width: 100%;
height: 0;
padding-bottom: 56.27198%;
}
.video-container iframe {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
The HTML:
<div class="video-container">
<iframe width="560px" height="315px" src="https://www.youtube.com/embed/XXXXxxxx?&theme=dark&autohide=2&iv_load_policy=3"><iframe>
</div>
You can use style="max-width: %87; max-height: %87;"
In addition to Darwin and Todd the following solution will
avoid the bottom margin
maximize the width for large screens
minimize the height in mobile view
keep a fixed size for #media none compatible browsers
The HTML:
<div class="video_player">
<div class="auto-resizable-iframe">
<div>
<iframe frameborder="0" allowfullscreen="" src="http://www.youtube.com/embed/_OBlgSz8sSM"> </iframe>
</div>
</div>
</div>
The CSS:
.videoplayer{
text-align: center;
vertical-align: middle;
background-color:#000000;
margin: 0;
padding: 0;
width: 100%;
height:420px;
overflow:hidden;
top: 0;
bottom: 0;
}
.auto-resizable-iframe {
width:100%;
max-width:100%;
margin: 0px auto;
}
.auto-resizable-iframe > div {
position: relative;
padding-bottom:420px;
height: 0px;
}
.auto-resizable-iframe iframe {
position: absolute;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
}
//full screen
#media (min-width:0px) {
.videoplayer{
height:100%;
}
.auto-resizable-iframe > div {
padding-bottom:100%;
}
}
//mobile/pad view
#media (min-width:600px) {
.videoplayer{
height:420px;
}
.auto-resizable-iframe > div {
padding-bottom:420px;
}
}
There are a few suggestions on the list of answers to use js to modify the structure of generated iframe. I think there is a risk with that because when you wrap the iframe inside other elements it's possible that the YouTube API will lose 'connection' with the iframe (especially if you pass the element in as a node instead of using specific id like me). It's rather to get around it actually, use javascript to modify the content before you actually trigger the youtube player.
a snippet from my code:
/**
* Given the player container, we will generate a new structure like this
*
* <div class="this-is-the-container">
* <div class="video-player">
* <div class="auto-resizable-iframe">
* <div>
* <iframe frameborder="0" allowfullscreen="" src="http://www.youtube.com/embed/_OBlgSz8sSM"> </iframe>
* </div>
* </div>
* </div>
* </div>
*
* #return {Node} the real player node deep inside
*/
YouTube.renderResizable = function (playerContainer) {
// clean up the content of player container
playerContainer.textContent = '';
var playerDiv = document.createElement('div');
playerDiv.setAttribute('class', 'video-player');
playerContainer.appendChild(playerDiv);
// add the auto-resizable-frame-div
var resizeableDiv = document.createElement('div');
resizeableDiv.setAttribute('class', 'auto-resizable-iframe');
playerDiv.appendChild(resizeableDiv);
// create the empty div
var div = document.createElement('div');
resizeableDiv.appendChild(div);
// create the real player
var player = document.createElement('div');
div.appendChild(player);
return player;
};
Just set iframe height and width with CSS vw metric. It uses device width as parameter:
.videoWrapper iframe {
height: 36.6vw;
width: 65vw;
}
You could use two classes that would scale the size of the video based on the size of the wrapping div. Consider this example:
<div class="content-wrapper">
<div class="iframe-wrapper res-16by9">
<iframe src="https://www.youtube.com/embed/pHsYFURtzzY" frameborder="0" allowfullscreen></iframe>
</div>
</div>
Now look at the css.
.content-wrapper{
max-width: 800px;
margin: 0 auto;
background-color: #fff;
}
.iframe-wrapper{
width: 100%;
position: relative;
}
.res-4by3{
padding-bottom: 75%;
}
.res-16by9{
padding-bottom: 56.25%;
}
.iframe-wrapper iframe{
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
Note that you will have to wrap the iframe in a div who's width is set to 100% and position is set to relative. You have to also add a bottom-padding to iframe wrapper. This padding will define the height of a video. I recommend to create two classes that will represent the image ratio.
It is quite easy to calculate the right bottom-padding for wrappers that represent certain resolution. For example for res 4 by 3 and 16 by 9 would have bottom-padding equal to:
[4/3 res]
100 / 4 * 3 = 75%;
[16/9 res]
100 / 16 * 9 = 56.25%
Then position the iframe as absolute and push it to the top left corner of the wraping div. Also meke sure to set iframe width and height to 100%. You are done.
Add the class that fits the right resolution for you. It will scale the image width and height respectively keeping the right proportions in place.
The example above works for any iframe. Thats mean you can also use it for google maps iframe.
Add JavaScript code to give each youtube iFrame a class:
$('iframe[src*="youtube"]').addClass('youtube')
Then in the Media Queries use the you tube class to set a different size.
.youtube {
/* Do stuff here */
}
Easier and optimized to CMS than the manual way.
I'm trying to implement the latest sIFR. But I can't get even the simplest of tests to work. My test page is at http://www.kellymitchelljewelry.com/testsifr.asp. There should be an sIFR-generated line that says "2nd line" between the first and third lines. I'm using the examples provided on the sIFR page exactly.
My html looks like this:
<html>
<head>
<title>Kelly Mitchell Fine Jewelry</title>
<link rel="stylesheet" href="sifr.css" type="text/css">
<script src="sifr.js" type="text/javascript"></script>
<script src="sifr-config.js" type="text/javascript"></script>
</head>
<body>
First Line<br><br>
<h1>Second Line</h1>
<br>Third Line<br><br>
</body>
</html>
My sifr-config.js looks like this:
var cgoth = { src: 'cgoth.swf' };
sIFR.activate(cgoth);
sIFR.replace(cgoth, {
selector: 'h1'
});
My sifr.css file looks like this:
#media screen {
.sIFR-flash {
visibility: visible !important;
margin: 0;
padding: 0;
}
.sIFR-replaced, .sIFR-ignore {
visibility: visible !important;
}
.sIFR-alternate {
position: absolute;
left: 0;
top: 0;
width: 0;
height: 0;
display: block;
overflow: hidden;
}
.sIFR-replaced div.sIFR-fixfocus {
margin: 0pt;
padding: 0pt;
overflow: auto;
letter-spacing: 0px;
float: none;
}
}
#media print {
.sIFR-flash {
display : none !important;
height : 0;
width : 0;
position : absolute;
overflow : hidden;
}
.sIFR-alternate {
visibility : visible !important;
display : block !important;
position : static !important;
left : auto !important;
top : auto !important;
width : auto !important;
height : auto !important;
}
}
/*
Place CSS rules for to-be-replaced elements here. Prefix by .sIFR-active
so they only apply if sIFR is active. Make sure to limit the CSS to the screen
media type, in order not to have the printed text come out weird.
*/
#media screen {
.sIFR-active h1 {
font-family: Verdana;
visibility: hidden;
line-height: 1em;
}

I've tried recreating my swf file just in case I did something wrong, and closely followed the instructions to make sure I didn't leave anything out.
Can someone help me figure what I'm doing wrong?

I don't think your Flash movie is correct, opening it directly should show "Rendered with sIFR 3" text. Make sure it was exported correctly.
I have never been able to get a .swf file exported from Flash to work with sIFR. I've always ended up having to use the online sIFR generator: http://www.sifrgenerator.com/wizard.html
I don't know if my version of Flash (CS3) is just not compatible with sIFR or what... I do always save as version 8 like it says to, and make sure every setting is as it should be, but no luck. However, using that generator always seems to solve it. So if your Flash is jinxed to, you might want to give it a try.
