Show multiple file thumbnail on custom dropzone

I created custom dropzone in order to upload my files as the following example
function readFile(input) {
debugger;
if (input.files && input.files[0]) {
var reader = new FileReader();
for (let i = 0; i < input.files.length; i++) {
reader.onload = function(e) {
var htmlPreview =
'<img width="100" src="' +
e.target.result +
'" />' +
"<p>" +
input.files[i].name +
"</p>";
var wrapperZone = $(input).parent();
var previewZone = $(input)
.parent()
.parent()
.find(".preview-zone");
var boxZone = $(input)
.parent()
.parent()
.find(".preview-zone")
.find(".box")
.find(".box-body");
wrapperZone.removeClass("dragover");
previewZone.removeClass("hidden");
// boxZone.empty();
boxZone.append(htmlPreview);
};
}
reader.readAsDataURL(input.files[0]);
}
}
function reset(e) {
e.wrap("<form>")
.closest("form")
.get(0)
.reset();
e.unwrap();
}
$(".dropzone").change(function() {
readFile(this);
});
$(".dropzone-wrapper").on("dragover", function(e) {
e.preventDefault();
e.stopPropagation();
$(this).addClass("dragover");
});
$(".dropzone-wrapper").on("dragleave", function(e) {
e.preventDefault();
e.stopPropagation();
$(this).removeClass("dragover");
});
$(".remove-preview").on("click", function() {
var boxZone = $(this)
.parents(".preview-zone")
.find(".box-body");
var previewZone = $(this).parents(".preview-zone");
var dropzone = $(this)
.parents(".form-group")
.find(".dropzone");
boxZone.empty();
previewZone.addClass("hidden");
reset(dropzone);
});

As you can see it is a multiple-input file, so you can upload multiple files in the same dropzone.
as you can see in the readFile javascript function, I create the thumbnail, the problem is when selecting more than one file, it only shows one thumbnail, how can I display each of them each next to the other as:

Setting up a Slick Carousel, containing sliders as individual elements

I want to create a carousel like this one here:
https://codepen.io/newrya/pen/eYMZdKe
The catch is, I want to make an auto play carousel using "slick" and want the above slider as individual elements instead of images. This is my initial Code. So, instead of these img elements inside div having class horizontal. I want the above slider as the elements.
$('.horizontal').slick({
slidesToShow: 1,
slidesToScroll: 1,
autoplay: true,
autoplaySpeed: 100,
});
#slider img{
width: 350px;
height: 350px;
margin-right: 100px;
}
<section id="slider" style="background-color:#fefefe;height: 800px;">
<div class="horizontal">
<img src="images/imags/1.jpg" class="before_after">
<img src="images/imags/2.jpg" class="before_after">

I copied the codepen code and replaced it with my img elements and made some changes with the css code and pasted it in my styles sheet.
This is the code:
const slider = document.querySelector('#image-slider');
const wrapper = document.querySelector('.img-wrapper');
const handle = document.querySelector('.handle');
slider.addEventListener("mousemove", sliderMouseMove);
slider.addEventListener("touchmove", sliderMouseMove);
function sliderMouseMove(event) {
if (isSliderLocked) return;
const sliderLeftX = slider.offsetLeft;
const sliderWidth = slider.clientWidth;
const sliderHandleWidth = handle.clientWidth;
let mouseX = (event.clientX || event.touches[0].clientX) - sliderLeftX;
if (mouseX < 0) mouseX = 0;
else if (mouseX > sliderWidth) mouseX = sliderWidth;
wrapper.style.width = `${((1 - mouseX/sliderWidth) * 100).toFixed(4)}%`;
handle.style.left = `calc(${((mouseX/sliderWidth) * 100).toFixed(4)}% - ${sliderHandleWidth/2}px)`;
}
let isSliderLocked = false;
slider.addEventListener("mousedown", sliderMouseDown);
slider.addEventListener("touchstart", sliderMouseDown);
slider.addEventListener("mouseup", sliderMouseUp);
slider.addEventListener("touchend", sliderMouseUp);
slider.addEventListener("mouseleave", sliderMouseLeave);
function sliderMouseDown(event) {
if (isSliderLocked) isSliderLocked = false;
sliderMouseMove(event);
}
function sliderMouseUp() {
if (!isSliderLocked) isSliderLocked = true;
}
function sliderMouseLeave() {
if (isSliderLocked) isSliderLocked = true;
}
$('.horizontal').slick({
slidesToShow: 1,
slidesToScroll: 1,

For some, reason, in class "handle-circle", the code after '171' is not valid(it turns green).
The second problem I am facing is, the codepen slider doesn't work when I replaced it with the img elements. The 'mousemove' event is of no use when using it in carousels. How do I change that?

I think you might have issues with the slick mouse over binding conflicting with the mouse over your image, as a workaround you could iframe it and it will work like so
$(document).ready(function() {
$('.carousel').slick({
slidesToShow: 3,
dots: true,
centerMode: true,
});
});
html,
body {
background-color: #e74c3c;
}
.wrapper {
width: 100%;
padding-top: 20px;
text-align: center;
}
h2 {
font-family: sans-serif;
color: #fff;
}
.carousel {
width: 90%;
margin: 0px auto;
}
.slick-slide {
margin: 10px;
}
.slick-slide img {
width: 100%;
border: 2px solid #fff;
}
.wrapper .slick-dots li button:before {

Display the preview image before uploading it to the database

I have a button called to add more images so that the user can add multiple images.
Now, what I am doing, I have to display the preview image before uploading it to the database but it's not working as expected.
I referred to this link Preview images before upload
$(document).ready(function() {
var max_fields = 5;
var wrapper = $(".input_fields_wrap .row");
var add_button = $(".add_field_button");
var x = 1;
$(add_button).click(function(e) {
e.preventDefault();
if (x < max_fields) {
x++;
$(wrapper).append('<div class="col-lg-4 mb-3"><div class="customfileWrap"><div class=" upload_file"><input type="file" name="slider[]" class="fileupload" multiple><span class="excel_upload_icon"></span><p id="file-name"></p><span class="upload_text"> Click here to upload file </span> <div class="gallery"></div></div> ✖ </div></div>');
}
});
$(wrapper).on("click", ".remove_field", function(e) {
e.preventDefault();
$(this).parent('div').parent('div').remove();
x--;
})
});
$(function() {
// Multiple images preview in browser

}
reader.readAsDataURL(input.files[i]);
}
}
};
$('.fileupload').on('change', function() {
imagesPreview(this, 'div.gallery');
});
});

The problem is that you haven't delegated the event handlers for dynamically generated file uploads:
$wrapper.on('change', '.fileupload', function() {
imagesPreview(this, 'div.gallery');
});
const max_fields = 5;
const template = '<div class="col-lg-4 mb-3"><div class="customfileWrap"><div class=" upload_file"><input type="file" name="slider[]" class="fileupload" multiple><span class="excel_upload_icon"></span><p id="file-name"></p><span class="upload_text"> Click here to upload file </span> <div class="gallery"></div></div> ✖ </div></div>';
// Multiple images preview in browser
const imagesPreview = function() {
const input = this;
const $placeToInsertImagePreview = $(this).parent().find('div.gallery');
if (input.files) {
var filesAmount = input.files.length;
for (let i = 0; i < filesAmount; i++) {
var reader = new FileReader();
reader.onload = function(event) {
$($.parseHTML('<img>')).attr('src', event.target.result).appendTo($placeToInsertImagePreview);
}
reader.readAsDataURL(input.files[i]);
}
}
};
$(function() {
const $wrapper = $(".input_fields_wrap .row");
const $add_button = $(".add_field_button");
let fileUploadCount = 1;
$add_button.click(e => {
e.preventDefault();
if (fileUploadCount < max_fields) {
fileUploadCount++;
$wrapper.append(template);
}
});
$wrapper.on('click', '.remove_field', function(e) {
e.preventDefault();
$(this).closest('.customfileWrap').remove();
fileUploadCount--;
})
$wrapper.on('change', '.fileupload', imagesPreview);
});

text over img hover with jquery

I'm a complete beginner at coding and I've already searched here but I couldn't really find a proper solution to my problem.
I'm trying to get a text to appear in place of the image when I hover over the image with the mouse.
Unfortunately jQuery has to be used, I know it can be done by just using CSS.
So far I have the following which I found on here:
In the head:
<script>
$(function(){
$('.parent').mouseenter(function(){
$(this).children('.child').fadeIn();
}).mouseleave(function(){
$(this).children('.child').fadeOut();
});
});
</script>
In the body:
<div class='parent'>
<img src='https://ichef.bbci.co.uk/news/660/cpsprodpb/37B5/production/_89716241_thinkstockphotos-523060154.jpg' alt='image'/>
<div class='child'>
<p>Random text.</p>
</div>
</div>
CSS:
.parent
{
position:relative;
}
.child
{
position: absolute;
left: 0;
bottom: 0;
background-color: black;
opacity: 0.5;
padding:10px;
display:none;
}
Thank you for an easy tip or explanation on what I'm doing wrong and how I can solve that problem.
Edit:
This is my full code in my PHP file:
echo "
<!DOCTYPE html>
<html lang=\"en\">
<head>
<meta charset=\"UTF-8\">
<title>Test Blog</title>
<script>
$(document).ready(function() {
$('.gallery-item').hover(function() {
$(this).find('.img-title').fadeIn(300);
}, function() {
$(this).find('.img-title').fadeOut(100);
});
});
</script>
</head>
<body>
<script src=\"https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js\"></script>
<div class=\"wrapper clearfix\">
<figure class=\"gallery-item\">
<img src='https://ichef.bbci.co.uk/news/660/cpsprodpb/37B5/production/_89716241_thinkstockphotos-523060154.jpg' alt='image'>
<figcaption class=\"img-title\">
<h5>Random text.</h5>
</figcaption>
</figure>
</div>
And there it continues with a dropdown menu routing to the other pages.
The CSS code is in my CSS file which I linked to above (the link is correct since all the other CSS code is working).

$(document).ready(function() {
$('.gallery-item').hover(function() {
$(this).find('.img-title').fadeIn(300);
}, function() {
$(this).find('.img-title').fadeOut(100);
});
});
.gallery {
width: 25em;
margin: 2em auto;
}

You have to define the size of the overly - I did that with the position settings below. Also, I erased the opacity setting. Not sure what else you want, but basically it works now.
$(document).ready(function() {
$('.parent').mouseenter(function() {
$(this).children('.child').fadeIn();
}).mouseleave(function() {
$(this).children('.child').fadeOut();
});
});
.parent {
position: relative;
}
.child {
position: absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
background-color: black;
padding: 10px;
display: none;
}
.child p {
color: white;
text-align: center;
margin-top: 100px;
font-size: 30px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Hope it helps you out.

Top fixed Menubar, when linked to a certain div of the menu from another html

My problem is that i wanted to make a fixed menubar on top of the page when scrolled, that wasn't so hard, but the hard part for me is that, when i link it to a certain part from the menubar from external html the menubar shows up and it is fixed on the top of the page and it works perfectly when i scroll down, but when i scroll up, it stays there

It works for me, it's fixed when i scroll down, and when i come back on the top of the page it goes where it was at the beginning, i don't get your problem, can you be more specific?

Well, to be more specific, i have the menubar that is fixed when i scroll down or up and it work perfectly when i open this specific html. This menubar contain 7 submenus and my idea is that when i use an external html with link to for example submenu 3 using (it opens this specific html and scroll down to submenu 3)but the menubar doesnt move when i scroll up , it only works(stay fixed at the top)when i scroll down
