CSS transition animation order issue for accordion

I have exampled below two div boxes with <h4> headers and followed with <p> with text. In an accordion style, I want to click each title and see the text appear, I've done this by setting the text div container box to max-height: 0; and opacity: 0; then max height a value and opacity 1 on click.
My issue is that I expect the animation to happen simultaneously for both boxes (one that slides up and hides, the other that slides down and appears), However, I get the animation running in order slide up and disappear forwarded by slide down and appear.
How can I get them both at the same time?

}

CSS transition works only if Chrome Dev Tools open

I've run into a bizarre anomaly with CSS transitions. The transition is completely ignored on load; but if I open up Chrome Dev Tools and navigate the DOM tree to #popup > div > img and select it, then click on the main image, the transition becomes functional, and remains so even if Dev Tools is closed.
My suspicion is that I've made some weird mistake that I can't see. But when opening Dev Tools to try to probe my CSS makes it suddenly start working, it's a bit hard to debug!
Tested on Chrome 66.0.3359.139. The behaviour is the same in Codepen and as a stand-alone HTML file.
My intention is for clicking on the small image to show a larger one. With the popup visible, clicking anywhere will dismiss that popup. Both showing and dismissing the popup should transition smoothly; for this demo, that's an opacity change followed by a change to the image's top (making it scroll in from above the screen). The popup is controlled by setting a class on the HTML element.
document.getElementById("clickme").onclick = function(ev) {
document.documentElement.classList.add("show-modal");
ev.stopPropagation();
}
document.documentElement.onclick = function() {
this.classList.remove("show-modal");
}
#clickme {
max-height: 300px;
cursor: pointer;
margin: 20px;
border: 1px solid #ddd;
border-radius: .25rem;
padding: 10px;
}
#popup {
position: fixed;
width: 100%;
height: 100%;
left: 0;
top: 0px;
z-index: 2000;
padding-top: 30px;
display: none;
}
.show-modal #popup {
display: block;
}
#popup img {
display: block;
margin: auto;
position: relative;
top: -500px;
opacity: 0;
transition: top .5s 1s, opacity .25s;
}
.show-modal #popup img {
top: 0px;
opacity: 1;
}
#popup>div {
margin: auto;
}

CSS can't animate between display: none; and display: block; (of the #popup element). I changed to visibility for #popup.
You can see the new code here: https://codepen.io/anon/pen/KRoPwM. Hope this helps.

How to animate multiple elements, when using the same classes?

I'm am trying to make multiple boxes, which can expand onclick and close again when clicking on the X. Well first off, the close jquery doesn't work, but that isn't the main thing I'am looking fore, how can I optimize the code, so doesn't become 400-600 hundred lines of the same, just for each box/element.
When click on one box/element, it should expand and so should the content inside - in the order as they come. Then it can be closed again an you would be able to click on another element with the same result - using pretty much the same code.
How can I make the site know, which element has bin click on.
Thanks in advance :)

So, you have multiple boxes that you want to expand/shrink on click. You can give all that boxes one class - boxExpandable for expample, with initial width. Then user clicks on boxExpandable - you should toggle .expanded class with higher width.
If you want some content to be shown only when box is expanded - wrap it in .showWhenExpanded class, like shown below.
$(document).ready(function(){
$('.expandableBox').on('click', function(){
$(this).toggleClass('expanded');
});
});
.box {
margin-bottom: 10px;
padding: 15px;
width: 40%;
border: solid 5px goldenrod;
transition: background-color .4s, width .4s;
}
.box:hover {
background-color: #32cd32;
}
.box.expanded {
width: 80%;
}
.showWhenExpanded {
display: none;
}
.box.expanded .showWhenExpanded {
display: inline-block;
}
<script src="//code.jquery.com/jquery.js"></script>
<div class="content">
<div class="box expandableBox">
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. <span class="showWhenExpanded">Duis aliquam nunc sit amet ante lacinia, vitae dictum erat egestas. Duis rutrum vitae orci vitae euismod.</span></p>
</div>
<div class="box expandableBox">

only first FAQ element expands on click - jquery

I'm trying to create an FAQ list. The answer displays fine on first click but I want to be able to click on another question and have that answer expand and the other close. Here's the javascript:
$(document).ready(function() {
// hide all the answers
$('.faq li div').hide();
$('.faq li').click(function(){
var question = $(this);
var answer = $(this).find('div');
// if the faq isn't active
if(!$('.faq li').hasClass('active')) {
answer.slideDown();
$(this).siblings('div').slideUp();
question.addClass('active');
}
else {
answer.slideUp();
question.removeClass('active');
}
});
});
The CSS:
ul.faq {
list-style:none;
cursor:pointer;
z-index:1;
}
ul.faq li h3 {
background:#0A5C75 url(../images/faq-inactive.png) right no-repeat;
color:#fff;
padding:20px 50px 20px 10px;
margin-bottom:10px;
border:1px solid #fff;
}
ul.faq li.active h3 {
background:#0A5C75 url(../images/faq-active.png) right no-repeat;
}
ul.faq li div {
background:#FFFFFF;
margin:0px 10px 10px 10px;
padding:20px;
overflow:hidden;
/* added fixed width to stop the jerkyness*/
width:522px;
position:relative;
top:-10px;
box-shadow: inset 0px 4px 4px 0px rgba(63, 70, 76, 0.15), 0px 4px 4px rgba(63, 70, 76, 0.15);
}
and the HTML
<ul class="faq">
<li>
<h3>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut arcu magna, sodales vel dignissim pharetra, adipiscing sed orci?</a></h3>
<div>Vivamus rutrum arcu sit amet dolor pulvinar dictum. Etiam porttitor leo eget velit volutpat quis ultricies urna ornare. Quisque ac ultrices est. Ut lobortis malesuada justo, sed blandit sapien bibendum et. Donec vel ante eu orci pellentesque dictum. Phasellus molestie egestas du</div>
</li>
<li>
<h3>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut arcu magna, sodales vel dignissim pharetra, adipiscing sed orci?</a></h3>
<div>This is the answer to question 2</div></li>
<li>
<h3>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut arcu magna, sodales vel dignissim pharetra, adipiscing sed orci?</a></h3>
<div>This is the answer to question 3</div>
</li>
</ul>

I think I could improve on your code a bit and produce the behavior and also shorten the code by a fair bit.
Notice, I skipped using your active class in order to show how it could be achieved.
Here's a tinker.io for demo I tested it in FF13 and Chrome
$('.faq li div').hide();
$('.faq li').click(function(event) {
var clickedQuestion = event.target;
var answer = $(clickedQuestion).siblings('div');
if($('ul.faq').find('div').is(':visible')){
$('ul.faq').find('div').slideUp();
}
answer.slideDown();
});

Working demo http://jsfiddle.net/e3Bec/ OR http://jsfiddle.net/XGJXM/
Your code is fine only thing is use ==> if (!$(this).hasClass('active')) { instead of if(!$('.faq li').hasClass('active')) { :) Also you don't need this in your first conditional check question.addClass('active');
Rest code should help, :)
code
$(document).ready(function() {
// hide all the answers
$('.faq li div').hide();
$('.faq li').click(function() {
$('div').slideUp();
var question = $(this);
var answer = $(this).find('div');
// if the faq isn't active
if (!$(this).hasClass('active')) {
answer.slideDown();
$(this).siblings('div').slideUp();
//question.addClass('active');
}
else {
answer.slideUp();
question.removeClass('active');
}
});
});​

I like that you are not sliding up the element if it is already visible.
Maybe move the .hide into css "display:none", no point waiting for the dom to load to hide them.
$(document).ready(function() {
$('.faq li').click(function(event){
$(this).find('div').not(":visible").slideDown();
$('.faq li div:visible').not($(this).find('div')).slideUp();
});
});

Why not use a Accordion. http://jqueryui.com/demos/accordion/

JavaScript animate resizing div

I'm trying to put a small animation on a page. I've got 2 divs side by side, the second of which has its content called via Ajax, so the div height varies without page refresh.
<div id="number1" style="float:left; padding-bottom:140px">Static content, 200px or so</div>
<div id="number2" style="float:left">AJAX content here</div>
<div style="clear:left"></div>
<img src="image" margin-top:-140px" />
This basically gives me a 2 column layout, and the image nests up underneath the left hand column no matter what the height. All good!
The thing I'm trying to do though is animate the transition of the image when the page height changes thanks to incoming Ajax content. At present the image jerks around up and down, I'd quite like to have it smoothly glide down the page.
Is this possible? I'm not really into my JavaScript, so I'm not sure how to do this. I'm using the jQuery library on the site, so could that be a way forward?

OK, I've just put together a very quick and dirty example.
Here's the HTML:
<body>
Add content
<div id="outerContainer">
<div id="left" class="col">
<p>Static content</p>
<img src="images/innovation.gif" width="111px" height="20px">
</div>
<div id="right" class="col">
<p>Ajax content</p>
</div>
</div>
</body>
The jQuery used is here
jQuery(function($){
var addedHTML = "<p class='added'>Lorem ipsum dolor sit amet, Nunc consectetur, magna quis auctor mattis, lorem neque lobortis massa, ac commodo massa sem sed nunc. Maecenas consequat consectetur dignissim. Aliquam placerat ullamcorper tristique. Sed cursus libero vel magna bibendum luctus. Nam eleifend volutpat neque, sed tincidunt odio blandit luctus. Morbi sit amet metus elit. Curabitur mollis rhoncus bibendum. Phasellus eget metus eget mi porttitor lacinia ac et augue. Nulla facilisi. Nam magna turpis, auctor vel vehicula vitae, tincidunt eget nisl. Duis posuere diam lacus.</p>";
$("#addContent").click(function(e){
$("#right").append(addedHTML);
var rightHeight = $("#right").height();
//Animate the left column to this height
$("#left").animate({
height: rightHeight
}, 1500);
});});
And CSS:
#outerContainer {
position: relative;
border: 1px solid red;
margin: 20px auto 0;
overflow: hidden;
width: 400px;}
.col {
width: 180px;
display: inline;
padding: 0 0 40px;}
#left {
float: left;
border: 1px solid cyan;
position: relative;}
#left img {
position: absolute;
bottom: 0;
left: 0;}
#right {
position: absolute;
top: 0;
left: 180px;
border: 1px solid green;}
#addContent {
text-align: center;
width: 100px;
margin: 20px auto 0;
display: block;}
I have added a button just to add some 'Ajax' content. When you do this it grabs the new height of the div and animates to that height. You could add some easing to the animation / change the speed to make it a little more polished.
I hope this helps.

Maybe you could use a container around the content divs (with overflow hidden) and resize that one according to the height of the contents, thus achieving what you're trying to do?

I agree with the answer above. You could apply the image as a background image to the container then animate the container. That way the background image will move down with the container (assuming you anchor it to the bottom that is!)
