Show loading progress bar till the page load

I want to show loading progress bar till the page load. If the internet might be slow and page take more to load, the progress bar show till the page fully load.
I attempted to add code, but because internet speeds vary, it is inaccurate. Could you please help me with this? I want to add a progress bar that starts at 0% while the page is loading and goes up to 100% after the page is completely loaded, dependent on the page loading speed.
$(window).on('load', function() {
$('#preloader').fadeOut(500);
$('body').removeClass('pre_loader');
});
var width = 100,
perfData = window.performance.timing, // The PerformanceTiming interface represents timing-related performance information for the given page.
EstimatedTime = -(perfData.loadEventEnd - perfData.navigationStart),
time = parseInt((EstimatedTime / 1000) % 60) * 100;
// Loadbar Animation
$(".loadbar").animate({
width: width + "%"
}, time);
// Percentage Increment Animation
function animateValue(id, start, end, duration) {
var range = end - start,
current = start,
increment = end > start ? 1 : -1,
stepTime = Math.abs(Math.floor(duration / range)),
obj = $(id);
var timer = setInterval(function() {
current += increment;
$(obj).text(current + "%");
//obj.innerHTML = current;
if (current == end) {
clearInterval(timer);
}
}, stepTime);
}
// Fading Out Loadbar on Finised
setTimeout(function() {
$('.preloader-wrap').fadeOut(100);
}, time);
<div class="preloader-wrap">
<div class="loader">
<div class="trackbar">
<div class="loadbar">

Sound like CSS (only) animation would be an option to consider. Inline your progress bar and it's <style> first thing as the page loads. Then remove then and make the body visible again on page load event. You can cheat time if you use some easing function that will never finish.
If you need numbers in your progress bar, then there is an options for that; even by a variable in modern browsers https://css-tricks.com/animating-number-counters/
For example (need to play with the percent values a bit):
<!-- almost first thing on page -->
<style>
.container {
width: 400px;
height: 50px;
position: relative;
border: 1px solid black;
}
.progress {
background: blue;
float: left;
color: white;
width: 100%;
height: 50px;
line-height: 50px;
animation-name: slideInFromLeft;
animation-duration: 30s;
animation-timing-function: cubic-bezier(0, .9, .9, .999);
text-align: center;
}
.percent::before {
content: counter(count);
animation-name: counter;
animation-duration: 30s;
animation-timing-function: cubic-bezier(0, .9, .9, .999);
counter-reset: count 0;
}
#keyframes slideInFromLeft {
0% {
width: 0%;
}
99% {
width: 99%;
}
}
#keyframes counter {
0% {
counter-increment: count 0;
}
10% {
counter-increment: count 50;
}
20% {
counter-increment: count 60;
}
30% {
counter-increment: count 70;
}
40% {
counter-increment: count 80;
}
50% {
counter-increment: count 90;
}
60% {
counter-increment: count 95;
}
70% {
counter-increment: count 98;
}
80% {

}
90% {

100% {

How do I fix my code such that the linear interpolation doesn't cross over?

I'm trying to make an infinite marquee (scrolling horizontal text), but on scroll it speeds up the translation of the HTML elements. I am achieving this effect by using a linear interpolation function.
You can see the effect on this site that I'm trying to remake: https://altsdigital.com/ It says "Not your usual SEO agency"
Mine almost works - the problem is that when my HTML resets its position - my text overlaps and briefly translates to the left before correcting. Keep your eyes on the left side of the page. You will see that the text overlaps at one brief moment then translates left (during it's movement to the right), it eventually corrects itself as it plays retaining the original gap. You can see in this screenshot the "t" and "I" are overlapping. Shortly after this, the text on the left translates left and there is a gap between the letters. I want it to have a gap and not briefly translate left.
I have no idea how to fix this - I've tried calling the lerp function on scroll but nothing seems to change. Thanks in advance.
Here's the code:
const lerp = (current, target, factor) => {
let holder = current * (1 - factor) + target * factor;
holder = parseFloat(holder).toFixed(3);
return holder;
};
class LoopingText {
constructor(DOMElements) {
this.DOMElements = DOMElements;
this.lerpingData = {
counterOne: { current: 0, target: 0 },
counterTwo: { current: 100, target: 100 },
};
this.interpolationFactor = 0.1;
this.direction = true;
this.speed = 0.2;
this.render();
this.onScroll();
}
onScroll() {
window.addEventListener("scroll", () => {
this.lerpingData["counterOne"].target += this.speed * 5;
this.lerpingData["counterTwo"].target += this.speed * 5;
});
}
lerp() {
for (const counter in this.lerpingData) {
this.lerpingData[counter].current = lerp(
this.lerpingData[counter].current,
this.lerpingData[counter].target,
this.interpolationFactor
);
}
this.lerpingData["counterOne"].target += this.speed;
this.lerpingData["counterTwo"].target += this.speed;
if (this.lerpingData["counterOne"].target < 100) {
this.DOMElements[0].style.transform = `translate(${this.lerpingData["counterOne"].current}%, 0%)`;
} else {
this.lerpingData["counterOne"].current = -100;
this.lerpingData["counterOne"].target = -100;
}
if (this.lerpingData["counterTwo"].target < 100) {
this.DOMElements[1].style.transform = `translate(${this.lerpingData["counterTwo"].current}%, 0%)`;
} else {
this.lerpingData["counterTwo"].current = -100;
this.lerpingData["counterTwo"].target = -100;
}
}
render() {
this.lerp();
window.requestAnimationFrame(() => this.render());
}
}
let textArray = document.getElementsByClassName("item");
new LoopingText(textArray);

How Can I make this touch Slider move atomically?

I am trying to make this touch slider, which move between slides automatically.
I tried many ways but nothing helped, this bellow is my Code:
.slider-container {
height: 100vh;
display: inline-flex;
overflow: hidden;
scrollbar-width: none;
transform: translateX(0);
will-change: transform;
transition: transform 0.3s ease-out;
cursor: grab;
}
.slide{
max-height: 100vh;
width: 100vw;
display: flex;
align-items: center;
justify-content: center;
padding: 1rem;
}
<div class="slider-container">
<div class="slide">
<img src="pics/slider/127616685-multi-colored-samples-of-marble-granite-and-travertine-chips-and-pebbles-for-landscape-design-close-.jpg"/>
</div>
<div class="slide">
<img src="pics/slider/1554689647283.jpg"/>
</div>
</div>

Just add this code at the bottom of your JS code.
This code changes the value of currentTranslate every 1 second and then calls the touchEnd(); function.
**I added the variable "loop" if the value is true when the last slide is reached... the script will call the first one again and so on indefinitely. If it has a value of false when the last slide is reached, the interval will be removed. And scrolling the slides will stop.
var loop = true; //<-- "true" Loop or "false" Stop on the End
var slideShw = setInterval(() => {
currentTranslate = currentTranslate - 101;
touchEnd();
if (currentIndex === slides.length - 1) {
if (loop) {
currentIndex -= slides.length;
} else {
stop_slideShw();
}
}
}, 1000);
function stop_slideShw() {
clearInterval(slideShw);
}
Example:
// get our elements
const slider = document.querySelector('.slider-container'),
slides = Array.from(document.querySelectorAll('.slide'))
// set up our state
let isDragging = false,
startPos = 0,
currentTranslate = 0,

// touch events
slide.addEventListener('touchstart', touchStart(index))
slide.addEventListener('touchend', touchEnd)
slide.addEventListener('touchmove', touchMove)
// mouse events
slide.addEventListener('mousedown', touchStart(index))
slide.addEventListener('mouseup', touchEnd)
slide.addEventListener('mousemove', touchMove)

})
// make responsive to viewport changes
window.addEventListener('resize', setPositionByIndex)
// // prevent menu popup on long press
// window.oncontextmenu = function (event) {

To move your slider automatically you should use the animation property.

Its difficult to work on slider without Javascript. I am giving some fresh codes, you can check them and rewrite your codes accordingly.
var photos = ["1.png","2.png","3.png"]
var time = 3000;
var imgTag = document.querySelector("img")
var count = 0;
function changeImg() {
document.slide.src = photos[count];
count++;
if(count==3){
count=0;
imgTag.src = photos[count];
}
else{
imgTag.src = photos[count];
}
console.log("lap");
setTimeout("changeImg()",time);
}
window.onload = changeImg;
function next(){
count++;
time=3000;
if(count==3){
count=0;
imgTag.src = photos[count];
}
else{
imgTag.src = photos[count];
}
console.log("next");
}
function prev(){
count--;
time=3000;
if(count==-1){
count=2;
imgTag.src = photos[count];
}
else{
imgTag.src = photos[count];
}
console.log("prev");
}

Put any 3 images named "1.png" "2.png" "3.png". And then run the code. Hopefully it will run, and you will get an idea. Here I have used a setTimeout function that will fire up after 3 seconds to change your slides.
Thank you.

What could be the bare minimum steps to animate the following carousel implementation?

I am making a vanilla js carousel. I have laid out basic previous and next functionality using js along with html and css.
Now I tried to use css-animations (keyframes) to do left and right slide-in/slide-out animations but the code became messy for me. So here I am asking that what minimal changes would be needed to get the same animation effects in this implementation ?
Will you go for pure JS based or pure CSS based or a mix to do the same ?
My goal is get proper animation with minimal code.
(function () {
let visibleIndex = 0;
let carousalImages = document.querySelectorAll(".carousal__image");
let totalImages = [...carousalImages].length;

visibleIndex = 0;
}
resetVisible();
renderVisible();
}

if (visibleIndex < 0) {
visibleIndex = totalImages - 1;
}
resetVisible();
renderVisible();
}

Updated codepen with feedback from the below answers and minor additional functionalities = https://codepen.io/lapstjup/pen/RwoRWVe

I think the trick is pretty simple. ;)
You should not move one or two images at the same time. Instead you should move ALL images at once.
Let's start with the CSS:
.carousal {
position: relative;
display: block;
}
.carousal__wrapper {
width: 500px;
height: 400px;
position: relative;
display: block;
overflow: hidden;
margin: 0;
padding: 0;
}
.carousal__wrapper,
.carousal__images {
transform: translate3d(0, 0, 0);
}
.carousal__images {
position: relative;
top: 0;
left: 0;
display: block;
margin-left: auto;
margin-right: auto;
}
.carousal__image {
float: left;
height: 100%;
min-height: 1px;
}
2nd step would be to calculate the maximum width for .carousal__images. For example in your case 4 * 500px makes 2000px. This value must be added to your carousal__images as part of the style attribute style="width: 2000px".
3rd step would be to calculate the next animation point and using transform: translate3d. We start at 0 and want the next slide which means that we have slide to the left. We also know the width of one slide. So the result would be -500px which also has to be added the style attribute of carousal__images => style="width: 2000px; transform: translate3d(-500px, 0px, 0px);"
That's it.
Link to my CodePen: Codepen for Basic Carousel with Autoplay

Try this. First stack all the images next to each other in a div and only show a single image at a time by setting overflow property to hidden for the div. Next, add event listeners to the buttons. When a bottom is clicked, the div containing the images is translated by -{size of an image} * {image number} on the x axis. For smooth animation, add transition: all 0.5s ease-in-out; to the div.
When someone clicks left arrow on the first image, the slide should display the last image. So for that counter is set to {number of images} - 1 and image is translated to left size * counter px.
For every click on the right arrow, the counter is incremented by 1 and slide is moved left. For every click on the left arrow, the counter is decremented by 1.
Slide.style.transform = "translateX(" + (-size * counter) + "px)"; this is the condition which is deciding how much the slide should be translated.
const PreviousButton = document.querySelector(".Previous-Button");
const NextButton = document.querySelector(".Next-Button");
const Images = document.querySelectorAll("img");
const Slide = document.querySelector(".Images");
const size = Slide.clientWidth;
var counter = 0;
// Arrow Click Events
PreviousButton.addEventListener("click", Previous);
NextButton.addEventListener("click", Next);
function Previous() {
counter--;
if (counter < 0) {
counter = Images.length - 1;
}
Slide.style.transform = "translateX(" + (-size * counter) + "px)";
}
function Next() {
counter++;
if (counter >= Images.length) {
counter = 0;
}
Slide.style.transform = "translateX(" + (-size * counter) + "px)";
}

I have been trying using jquery animate to do a running text. But I can't seems to get it run in an endless loop. It always runs one time only..
/* js: */
$(document).ready(function(){
function scroll() {
$('.scroll').animate({
right: $(document).width()
}, 8000, scroll);
}
scroll();
});
/* css： */
.scroll {
position: absolute;
right: -200px;
width: 200px;
}
<!-- html: -->
<div class="scroll">This text be scrollin'!</div>
This is the demo:
https://jsfiddle.net/y9hvr9fa/1/
Do you guys know how to fix it?

So this is what I did:
Precalculate $(document).width() as if a horizontal scroll appears, the width will change in the next iteration
Remove the width you have set for scroll so that the width is only as long as the content - and you would have to give white-space:nowrap to keep the text in a line.
In the animate use the width of the scroll text using $('.scroll').outerWidth()
See demo below and update fiddle here
$(document).ready(function() {
// initialize
var $width = $(document).width();
var $scrollWidth = $('.scroll').outerWidth();
$('.scroll').css({'right': -$scrollWidth + 'px'});
// animate
function scroll() {
$('.scroll').animate({
right: $width
}, 8000, 'linear', function() {
$('.scroll').css({'right': -$scrollWidth + 'px'});
scroll();
});
}
scroll();
});
body {
overflow: hidden;
}
.scroll {
position: absolute;
white-space: nowrap;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="scroll">This text be scrollin'!</div>
Let me know your feedback on this, thanks!

CSS Alternative:
Alternatively you could use a CSS transition like in this CodePen:
https://codepen.io/jamesbarnett/pen/kfmKa
More advanced:
$(document).ready(function(){
var scroller = $('#scroller'); // scroller $(Element)
var scrollerWidth = scroller.width(); // get its width
var scrollerXPos = window.innerWidth; // init position from window width
var speed = 1.5;
scroller.css('left', scrollerXPos); // set initial position
function moveLeft() {
if(scrollerXPos <= 0 - scrollerWidth) scrollerXPos = window.innerWidth;
scrollerXPos -= speed;
scroller.css('left', scrollerXPos);
window.requestAnimationFrame(moveLeft);
}
window.requestAnimationFrame(moveLeft);
});
.scroll {
display: block;
position: absolute;
overflow: visible;
white-space: nowrap;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="scroller" class="scroll">This text be scrollin'!</div>
Dirty solution (my original answer):
In this example this would be a quick fix:
The text is running to the left without ever stopping. Here you will tell the text to always start at that position. (After the time has run up - meaning not necessarily just when it has left the screen)
$(document).ready(function(){
function scroll() {
$('.scroll').css('right', '-200px').animate({
right: $(document).width()
}, 8000, scroll);
}
scroll();
});

I have been trying using jquery animate to do a running text.
You know that the <marquee> HTML element works, right?
Which means you don't need CSS, Javascript or jQuery.
Pure HTML Solution:
<marquee>This text be scrollin'!</marquee>
The <marquee> element includes a large number of optional declarative attributes which control the behaviour of the scrolling text:
behavior
bgcolor
direction
height
hspace
loop
scrollamount
scrolldelay
truespeed
vspace
width
Further Reading:

Note 1:
The resource above correctly notes that:
This feature is no longer recommended. Though some browsers might
still support it, it may have already been removed from the relevant
web standards, may be in the process of being dropped, or may only be
kept for compatibility purposes.
Note 2
The same resource also recommends:
see the compatibility table at the bottom of this page to guide your decision
And... a cursory look at that compatibility table shows that the <marquee> element is as browser-compatible as the most established, most browser-compatible elements which exist today.

I hope it is useful :)
