How can I move tiles in circularly in a multi-row carousel?

I'm trying to create a tile-like content carousel for a website I'm creating. Basically I need the ordinary content carousel functionality that comes in a lot of different jQuery plug-ins etc. - but instead of the slider being linear, I need the items to shift tiles in a circular manner like this:
Step 1:
Step 2:
Step 3:
I tried creating the setup using Flexbox and some simple jQuery:
$(document).ready(function () {
$(".item").each(function (index) {
$(this).css("order", index);
});
$(".prev").on("click", function () {
// Move all items one order back
$(".item").each(function (index) {
var currentOrder = parseInt($(this).css("order"));
if (currentOrder == undefined) {
currentOrder = index;
}
var newOrder = currentOrder - 1;
if (newOrder < 0) {
newOrder = 5;
}
$(this).css("order", newOrder);
});
});
$(".next").on("click", function () {
// Move all items one order forward
$(".item").each(function (index) {
var currentOrder = parseInt($(this).css("order"));
var newOrder = currentOrder + 1;
if (newOrder > 5) {
newOrder = 0;
}
$(this).css("order", newOrder);
});
});
});
.container {
display: flex;
flex-direction: row;
flex-wrap: wrap;
width: 500px;
}
.item {
width: 125px;
height: 75px;
color: white;
text-align: center;
font-size: 24px;
border: 1px solid white;
padding-top: 50px;
box-sizing: content-box;
background-color: rgb(42, 128, 185);
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button class="prev">Prev</button>
<button class="next">Next</button>
<div class="container">
<div class="item one">1</div>
<div class="item two">2</div>
<div class="item three">3</div>
<div class="item four">4</div>
<div class="item five">5</div>
<div class="item six">6</div>
</div>
but this leaves me with some unresolved issues:
How do I animate the tiles when changing the order (when clicking next/prev)?
How do I fix the order so that the items move in a continuous line instead of wrapping to the start of next line (I'd like the order to be like displayed in step 2 -> 3)?
Any existing plug-in (I've looked but can't find any) or codepen etc. would be very much appreciated as I'm not sure if my approach is maintainable (or even doable).
Thanks a bunch :)

I've used absolute position formula from index to (top, left). Then i've used jQuery to animate that. That's lame but can be improved if that's an issue. It looks nice.
const containerBox = document.querySelector('#container')
let divs = [...containerBox.querySelectorAll('div')]
var size = 100
var margin = 2
function get_top_left(pos) {
if (pos < divs.length / 2) {
return {
left: pos * size + margin * (pos),
top: 0
}
} else {
return {
left: (divs.length - pos - 1) * size + margin * (divs.length - pos - 1),
top: size + margin
}
}
}
var offset = 0
function draw() {
divs.forEach(function(div, index) {
var len = divs.length
index = ((index + offset) % len + len) % len
var pos = get_top_left(index);
//div.style.left = pos.left + "px"
//div.style.top = pos.top + "px"
$(div).animate({
"left": pos.left + "px",
"top": pos.top + "px"
})
})
}
next.onclick = _ => {
offset += 1
draw()
}
prev.onclick = _ => {
offset -= 1
draw()
}
draw();
#container {
display: flex;
flex-direction: row;
flex-wrap: wrap;
width: 500px;
height: 260px;
margin: 10px;
position: relative;
}
#container>div {

height: 66px;

text-align: center;
font-size: 24px;
border: 1px solid white;
padding-top: 34px;
box-sizing: content-box;
background: #2a80b9;
position: absolute;
top: 0;
left: 0;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button id="prev">Prev</button>

This kind of carousel ?
const

;
next.onclick =_=>
{
let divs = [...containerBox.querySelectorAll('div')]
nextOrder.forEach(n=> containerBox.appendChild( divs[n]) )
}
prev.onclick =_=>
{
let divs = [...containerBox.querySelectorAll('div')]
prevOrder.forEach(n=> containerBox.appendChild( divs[n]) )
}
#container {
display : flex;
flex-direction : row;
flex-wrap : wrap;
width : 500px;
margin : 20px;
}
#container > div {
width : 125px;

I really apreciate a hand.

I know that I'm late, but there is my approach how this can be done.
// generate items with different height
function generateItems(count) {
const arr = [];
for (let i = 0; i < count; i++) {
const div = document.createElement("DIV");
const height = Math.floor((Math.random() * 100) + 10);
div.setAttribute("style", `height: ${height}px`);
div.setAttribute("class", "items");
const t = document.createTextNode(i + 1);
div.appendChild(t);
arr.push(div);
}
return arr;
}
function createNewContainer(height) {
const new_container = document.createElement("DIV")
new_container.setAttribute("class", "new_container");
new_container.setAttribute("style", `height: ${height}px`)
document.body.appendChild(new_container);
return new_container;
}
function breakFrom(sourceContainerId, newContainerHeight) {
const srcContainer = document.getElementById(sourceContainerId);
const items = srcContainer.childNodes;
let new_container = createNewContainer(newContainerHeight);
let sumHeight = 0;
for (let i = 0; i < items.length; i++) {
let item = items[i];
if (item.offsetHeight > newContainerHeight) {
// stop!!! this item too big to fill into new container
throw new Error("Item too big.");
}
if (sumHeight + item.offsetHeight < newContainerHeight) {
// add item to new container
sumHeight += item.offsetHeight;
new_container.appendChild(item.cloneNode(true));
} else {
// create new container
new_container = createNewContainer(newContainerHeight);
new_container.appendChild(item.cloneNode(true));
// don't forget to set sumHeight)
sumHeight = item.offsetHeight;
}
}
// if you want to remove items from big_container
// for (let i = items.length - 1; i >= 0; i--) {
// srcContainer.removeChild(items[i]);
// }
}
// create big container with divs
const big_container = document.getElementById("big_container");
const items = generateItems(13);
items.forEach((div, index) => {
big_container.appendChild(div);
});
breakFrom("big_container", 300);
#big_container {
width: 150px;
background-color: #f1f1f1;
float: left;
}
.items {
background-color: gray;
border: 1px solid #000000;
text-align: center;
}
.new_container {
margin-bottom: 10px;
height: 300px;
width: 150px;
background-color: red;

This example gives you the ability to play with divs of random height. Hope, this will help you.

jQuery calculate the number of line breaks in a div?

So I have a div wrap whose size is a percentage of the screen width. Inside this wrap is multiple .item divs. As the window gets smaller it breaks into new lines obviously.
I wrote some code which basically takes the width of the wrap and divides it by the sum of the widths of the .item boxes. But the flaw is that it looks at it thinking how many boxes could fit in total, were one to mix and match them perfectly like building blocks, but that's not how it works because the ordering is stagnant.
How could I make this logic work?
CodePen
jQuery:
var itemWidth = 0;
var lineCount = 1;
$(window).on('resize', function(){
var lineWidth = $('.line').width();
var itemWidthSum = 0;
lineCount=1;
$('.item').each(function(index, element) {
if(itemWidthSum < (lineWidth - $(element).outerWidth())) {
itemWidthSum = itemWidthSum + $(element).outerWidth();
} else {
lineCount++;
itemWidthSum = 0;
}
});
});
HTML:

I fell miserable about not being able to finish the game. I really need help. Thanks in advance.

Well, first of all this question has been already asked and answered on SO and table cells are just the same as usual elements :)
Since you're using jQuery anyway, you can use .detach()
var element = $('td:eq(0) span').detach();
$('td:eq(1)').append(element);
Here's a jsfiddle.
Or, as proposed in this answer, you can use a native js solution.

How to rollover text on images dynamically using javascript/jquery

I am new to web development but highly fascinated by it. So, basically I am creating a light-box where thumbnails of images will be appear on screen and they will appear bigger in size when user clicks over them. Now, I want when user hovers over the gallery images/thumbnails then some text should appear over the current image with may be some animation or basically mouser-hover should cause some event to happen but I am unable to do it. Text should be added dynamically or may be previously stored in an array or something of that sort. Please have a look at my code and tell me how to modify it in order to achieve such effect and if you know a better and easier way to do so then feel free to share. Thank you so much!!

There might be some bugs in coding. Watch out.
This code is working for displaying images as thumbnails as a matrix and as slider in lightbox when clicked upon them. I am not able to figure out how to add hover functionality to initial thumbnails.
Jsfiddle :

I'd suggest putting a div inside the image div containing the text and then using CSS to hide/show it.

<div class='close'>
x
</div>
</div>
</div>
CSS:
.limage { position: relative; }
.caption { display: none; }
.limage:hover .caption { display: block; position: absolute;}

Why you using array to store the images? Anyways, assume that you still using array, below is some example code that you want try:
HTML:
<ul id="images">
</ul>
<!-- assume this is the place that you want to display the caption -->
<div id="caption"></div>
Javascript:
var images = new Array();
images[0] = "p1.png";
images[1] = "p2.png";
images[2] = "p3.png";
images[3] = "p4.png";
var captions = new Array();
captions[0] = "Picture 1";
captions[1] = "Picture 2";
captions[2] = "Picture 3";
captions[3] = "Picture 4";
var x = $("#images");
var y = $("#caption");
const prefix = "image-";
if you are using HTML5:
for (var i = 0; i < images.length; i++) {
x.append("<img class='roll' src='" + images[i] + "' data-caption='" + captions[i] + "'>");
}
$(".roll").mouseover(function(){
//do whatever effect here when mouse over
y.html($(this).attr("data-caption"));
});
If you want to backward compatible:
for (var i = 0; i < images.length; i++) {
x.append("<img id='" + prefix + i + "' class='roll' src='" + images[i] + "'>");
}
$(".roll").mouseover(function(){
//do whatever effect here when mouse over
var index = $(this).attr("id").substring(prefix.length);
y.html(captions[index]);
});
Hope that this will help.
