I'm working on this code but I have difficulties implementing properly. I wan to place the arrow in front of the question and synchronize the click event with the text.

Can you help me to fix the issue?
HTML:
<div class="container faq_wrapper">
<div class="row">
<div class="span10 offset1">

CSS:
.answer-wrapper {
display: none;

.arrow {
margin: 1em;
}
.arrow::before {
position: absolute;
content: '';
width: 0;
height: 0;
border: .5em solid transparent;
border-left-color: gray;
transform-origin: 0 50%;
transition: transform .25s;
}
.arrow.down::before {
transform: rotate(90deg);
transition: transform .25s;
}
JavaScript:
$(document)
.on('click','.row',function(){
$(this).find('.answer-wrapper').slideToggle();
})
.on('click','.faq-expand',function(){
$('.answer-wrapper').slideDown();
})
.on('click','.faq-collapse',function(){
$('.answer-wrapper').slideUp();
})
var arr = document.querySelector('.arrow');
arr.addEventListener('click', function(event) {
event.target.classList.toggle('down');
});
;
Here is a working fiddle with your javascript, the css still needs a bit of work:

Basically you were using the wrong selectors for your jQuery.
HTML:
<div class="container faq_wrapper">
<div class="row">
<div class="span10 offset1">

<div class="faq-all-actions">
<a class="faq-expand">Expand All</a> | <a class="faq-collapse">Collapse All</a></div>

</div>
<div class="row">
<div class="span10 offset1">
<div class="question-wrapper">
<div class="arrows">

</div>
</div>
</div>
</div>
</div>
jQuery:
$(document).ready(function() {
.on('click','.row .question-wrapper',function(){
$(this).find('.answer-wrapper').slideToggle();
$('.arrow').toggleClass('down');
})
.on('click','.faq-expand',function(){
$('.answer-wrapper').slideDown();
$('.arrow').addClass('down');
})
.on('click','.faq-collapse',function(){
$('.answer-wrapper').slideUp();
$('.arrow').removeClass('down');
})
});
you've added position:absolute but done nothing to position the arrow .
add the following styles :
.arrow {
position:relative; // you need to add position relative
margin: 1em;
padding-left:10px;
}
.arrow::before {
position: absolute;
left:100%; // define where you would like the arrow to be placed .
content: '';
width: 0;
height: 0;
border: .5em solid transparent;
border-left-color: gray;
transform-origin: 0 50%;
transition: transform .25s;
}
use position relative and left for perfectly positioning your arrow .
FIDDLE HERE
To put arrow in front of the question you can use right 0 like this:
.arrow::before {
position: absolute;
right: 0;
content: '';
width: 0;
height: 0;
border: .5em solid transparent;
border-left-color: gray;
transform-origin: 0 50%;
transition: transform .25s;
}
When you are layout an element on position absolute, you can "fix" the element relative to the parent if you want (top, bottom, right, left).
Add "left: 190px" to ".arrow::before"
.arrow::before {
position: absolute;
content: '';
width: 0;
height: 0;
border: .5em solid transparent;
border-left-color: gray;
transform-origin: 0 50%;
transition: transform .25s;
left: 190px;
}

I used a similar code as on W3Schools for designing the tooltip, you can find my use here (external link to my site). On my local computer, it works perfectly, as shown here (external link to Vimeo). The first part of the video is my local computer, while the latter part is my website which is linked above. I have uploaded the linked CSS file as well after updating it. I have hosted this for free on GitHub and linked it to Cloudflare Pages, so if that is causing the issue am mentioning it.
Adding bootstrap as a tag since I'm unsure if that is causing any issue, new to coding so adding it. Apologies if it's not the case.

Given two rows of cards, I'm trying to combine the following animations:
Move the first card on the first row over the second card on the second row.
This is done by changing the top and left style properties.
Flip the first card on the first row.
I'm flipping the card based on this w3schools example.
Move the second card on the first row to the left.
The card is moved to the left by giving the div next to it zero width.
Animation 3) seems to conflict with animation 2).
Normally, a 'flip' involves swapping the front facing div with the back facing div.
However, when animation 3) gives the parent div zero width, the front and back are no longer aligned and both sides can be seen.
The following snippet demonstrates that a 'flip' seems to work, while 'move and flip' goes wrong.
Can you help me fix this such that all animations work correctly together?
function flipCard() {
const flipCard = document.querySelector('.top .flip-card')
const rect = flipCard.getBoundingClientRect()
flipCard.classList.add('moving')
flipCard.classList.add('flipped')
return [flipCard, rect]
}
function moveFlipCard() {
const srcSleeve = document.querySelector('.top .sleeve')
srcSleeve.classList.add('closed')
const [srcFlipCard, srcRect] = flipCard()
const targetFlipCard = document.querySelectorAll('.bottom .sleeve')[1]
const targetRect = targetFlipCard.getBoundingClientRect()
const offset = {
top: targetRect.top - srcRect.top,
left: targetRect.left - srcRect.left,
}
srcFlipCard.style.top = offset.top + 'px'
srcFlipCard.style.left = offset.left + 'px'
}

TLDR: To solve this, I explicitly set transform-origin: 30px 0 0. Now the point around which a transformation is applied no longer depends on the size of the bounding box.
I now see where it goes wrong. The problem lies with the transform-origin.
The transform origin is the point around which a transformation is applied.
For animation 2) this corresponds to the point around which the card is rotated 180 degrees over the y-axis (transform: rotateY(180deg)).
The default value of the transform-origin property is 50% 50% 0, where the values correspond to the offset over the x-axis, y-axis and z-axis, respectively.
However, what does 50% mean? 50% of what?
Percentages refer to the size of bounding box
So, what's the bounding box of the flipped div? When I inspect <div class="flip-card-inner"> I see it has a dimensions 60x0:
where 60 corresponds to width: 60px of parent <div class="sleeve">.
So for <div class="flip-card-inner"> the default transform-origin is 30px 0 0. This is what I expect: the card rotates over its y-axis at a point that lies halfway over the x-axis, such that the card is in the same location when flipped.
Now let's see what happens when we apply animation 3), i.e. move the second card on the first row to the left by giving the div next to it zero width:
Now the bounding box is 0x0, because the parent <div class="sleeve closed"> has zero width. Since the bounding box has changed, so has the transform-origin: 50% of 0 is 0, so we get 0 0 0. The card now rotates over its y-axis at a point that lies on the left side of the card. This has the undesired effect that the flipped card does not end up at the same location as where it started.
To solve this, I explicitly set transform-origin: 30px 0 0. Now the point around which a transformation is applied no longer depends on the size of the bounding box.
Working example:
function flipCard() {
const flipCard = document.querySelector('.top .flip-card')
const rect = flipCard.getBoundingClientRect()
flipCard.classList.add('moving')
flipCard.classList.add('flipped')
return [flipCard, rect]
}
function moveFlipCard() {
const srcSleeve = document.querySelector('.top .sleeve')
srcSleeve.classList.add('closed')
const [srcFlipCard, srcRect] = flipCard()
const targetFlipCard = document.querySelectorAll('.bottom .sleeve')[1]
const targetRect = targetFlipCard.getBoundingClientRect()
const offset = {
top: targetRect.top - srcRect.top,
left: targetRect.left - srcRect.left,
}
srcFlipCard.style.top = offset.top + 'px'
srcFlipCard.style.left = offset.left + 'px'
}

flipButton.addEventListener('click', flipCard)
const moveFlipButton = document.getElementById('moveFlipCard')

As you might see I have fixed a kind of text box that will pop up when someone is hovering over that image, but honestly I want a slide-up effect that gone up slowly. Must be completely in pure JavaScript (no jQuery please!). Anyone knows how I can do that.
function show(myText) {
var elements = document.getElementsByClassName(myText)
for(var i = 0; i < elements.length; i++){
elements[i].style.visibility = "visible";
}
}
function hide(myText) {
var elements = document.getElementsByClassName(myText)
for(var i = 0; i < elements.length; i++){
elements[i].style.visibility = "hidden";
}
}
.text1 {
position: relative;
bottom: 28px;
text-align: center;
background-color: grey;
width: 100%;
height: 10%;

Here is a version of it that's totally javascript free, just using CSS. I'm going to edit this soon with a slight javascript addition (this current version requires you to have a fixed size).
.caption {
height: 250px;
width: 355px;
overflow: hidden;
}
.caption-image {
height: 100%;
}
.caption-text {
color: white;
padding: 10px;
background: rgba(0, 0, 0, 0.4);
transition: transform 400ms ease;
}
.caption-image:hover + .caption-text,
.caption-text:hover {
transform: translateY(-100%);
}
<div class="caption">
<img class="caption-image" src="http://faron.eu/wp-content/uploads/2013/05/Cheese.jpg" />
<div class="caption-text">Some words about how cheesy it is to use a picture of cheese for this example!</div>
</div>
<div class="caption">
<img class="caption-image" src="https://top5ofanything.com/uploads/2015/05/Tomatoes.jpg" />
<div class="caption-text">There's nothing witty to say about a tomato, maybe some you say I say stuff. But honstly I can't think of anything...</div>
</div>
Version with JS sizing:
Basically the same idea, but when the page is loading it sets certain styles so the images can be what ever size you like.
var captionSel = document.querySelectorAll('.caption');
for (let i = 0; i < captionSel.length; i++) {
let image = captionSel[i].querySelector(":scope > .caption-image");
let text = captionSel[i].querySelector(":scope > .caption-text");
text.style.width = image.clientWidth - 20 + "px";
captionSel[i].style.height = image.clientHeight + "px";
}
.caption {
overflow: hidden;
}
.caption-text {
color: white;
padding: 10px;
background: rgba(0, 0, 0, 0.4);
transition: transform 400ms ease;
}
.caption-image:hover + .caption-text,
.caption-text:hover {
transform: translateY(-100%);
}
<div class="caption">
<img class="caption-image" src="http://faron.eu/wp-content/uploads/2013/05/Cheese.jpg" />
<div class="caption-text">Some words about how cheesy it is to use a picture of cheese for this example!</div>
</div>
<div class="caption">
<img class="caption-image" src="https://top5ofanything.com/uploads/2015/05/Tomatoes.jpg" />
<div class="caption-text">There's nothing witty to say about a tomato, maybe some you say I say stuff. But honstly I can't think of anything...</div>
</div>
I'll give it to you even better: No javascript at all!
This is possible with pure CSS:
.tumb-wrapper {
position: relative;
overflow: hidden;
}
.text {
text-align: center;
background-color: grey;
width: 100%;
height: 10%;
font-size: 20px;
color: white;
opacity: 0.7;
display: block;
position: absolute;
bottom: -30px;
transition: 300ms;
left: 0;
}
.tumb-wrapper:hover .text {
bottom: 28px;
}
<div class="row">
<div class="col-md-6 col-sm-12">
<div class="tumb-wrapper">
<a href="http://www.bbc.com" target="_blank" class="image">
<img src="https://i.vimeocdn.com/portrait/8070603_300x300" class="project" alt="print-screen"/>
<div class="text">AAA</div>
</a>
</div>
</div>
<div class="col-md-6 col-sm-12">
<div class="tumb-wrapper">
<a href="http://www.cnn.com" target="_blank" class="image">
<img src="https://lh6.ggpht.com/mSKQgjFfPzrjqrG_d33TQZsDecOoVRF-jPKaMDoGIpMLLT1Q09ABicrXdQH6AZpLERY=w300" class="project" alt="print-screen"/>
<div class="text">BBB</div>
</a>
</div>
</div>
</div>
The transition css property animates whatever change you make. This way, when you hover over the .tumb-wrapper div, the .text div will slide up.
You should note however, that ancient IE versions won't be able to use this
I usually do this with only CSS.
Just save the first and second image right next to each other on one file... then you use css to change the position of the background image. To make things nicer i add a css-animation to the movement of the background image.
Example of my code:
<div id="thumb_Wrapper">
<div class="_Thumb">
<img src="images/Thumb.jpg" class="Animate_left">
</div>
</div>
The CSS
#_Container{position:absolute; bottom -60px; right:2px; width:626px; height:100px;}
._Thumb{position:relative; margin-right:4px; width:100px; height:80px; display:block; float:left; background:#EFEFEF; overflow:hidden;}
._Thumb > img{position:absolute; left:0; height:100%; background-size:cover; background-position:center;}
._Thumb > img:hover{left:-18px; cursor:pointer;}
CSS Animation
.Animate_left{transition:left .3s;}
Now all you have to do is swap out the image.
onHover - the image in the thumbnail will smoothly slide to the left; revealing the rest of the image/ showing the other image.
You can set how far to the left(or right) you want the thumb-image to first appear by adjusting the value of 'left' in the ._Thumb class.
You can set how far the image slides on hover by adjusting the img:hover{left:-18px} to what ever you like; instead of 18px.
I'm working on example of collapse event with mouse click:

How I can align the arrow and the question? Also when I expand the question the arrow is not fully rotated. Is there any solution for these problems?
HTML:
<div class="container faq_wrapper">
<div class="row">
<div class="span10 offset1">
<p>
</p>
<div class="faq-all-actions">
<a class="faq-expand">Expand All</a> | <a class="faq-collapse">Collapse All</a></div>
</div>
</div>
<div class="row">
<div class="span10 offset1">
<div class="question-wrapper">
<div class="arrows">
</div>
<div class="big-q">
Q</div>
<div class="question">
<div class="arrow" ></div><h6><font size="6">Can I try the software before I buy it?</font></h6></div>

CSS:
.answer-wrapper {
display: none;
}
.arrow::before {
position: absolute;
content: "";
display: inline-block;
/* By using an em scale, the arrows will size with the font */
width: 0.4em;
height: 0.4em;
border-right: 0.2em solid black;
border-top: 0.2em solid black;
transform: rotate(45deg);
margin-right: 0.9em;
}
.arrow.down::before {
transform: rotate(90deg);
transition: transform .25s;
}
.question h6 {
margin-left: 15px;
}
adding:
.arrow::before {
margin-top: 15px;
}
and changing transform: rotate(90deg); to:
.arrow.down::before {
transform: rotate(135deg);
}
A quick fix if you're going to keep the current font-size

SOLVED:
After re-reading the w3 spec for transforms, I realised the footer was being considered part of the 3d context due to DOM structure and was being affected by rotated elements. I simply put .cardsContainer inside of another element .cards3dContainer and the footer is now not considered part of the 3d context.
-webkit-perspective:1000px; seems to state that the 3d context begins at that point in the DOM.
Having a major problem with a container that is being rotated using css3 transforms and over-writing part of a buttons hit area in another div.
The transform visually works and the container is leaning back (using rotateX). However, the button in the footer, despite being of a higher z-index and naturally stacked to be above the container, is having its hit area ignored where the rotated container and the button visually overlap. The button still 'appears' to be on top of the rotated container, but acts like it is under it.
I should mention im using Less for the css (and all the Less code does work).
I've looked through lots of similar questions and the various solutions didn't work for me. Amongst those that didn't work (vendor prefixes omitted):
translate3d(0px, 0px, 0px);
transform-style: flat;
Here is the short version of the code:
html:
<div class="screen snap" style="display: block;">
<div class="container">**<!-- has perspective set to 1000 -->**
<div class="cardsContainer"> **<!-- is rotated on x using transform -->**
<div class="card" style="left: 130px; display: block;">
<div class="cardBack"></div>
<div class="cardFront" style="opacity: 0;">
<div class="cardContent">A piece of fruit.</div>
</div>
</div>
</div>
<footer>
**<!-- at certain screen sizes, when the container and footer overlap, top half of this buttons hit area is inactive-->**
<button class="checkButton">Start</button>
</footer>
</div>
</div>

After re-reading the w3 spec for transforms, I realised what the problem was.
-webkit-perspective:1000px; seems to state that the 3d context begins at that point in the DOM. I was applying the perspective style to the container which both the footer and the cardsContainer were part of. The footer was then being considered part of the 3d context due to DOM structure and was being affected by rotated elements.
I simply put .cardsContainer inside of another element .cards3dContainer and the footer is now not considered part of the 3d context because it is now not inside the dom structure which has perspective style set.
The new structure is now this:
.screen.snap .container{
.cards3dContainer{
-webkit-perspective:1000px;
.cardsContainer{
}
}
.footer{
}
}
Apologies to anyone who may have been working on an answer at the moment.
