Countdown is stopping when user is out of current tab

I create a simple countdown with a "invert" progress bar - to control session in my website.
when time is over, page will be reload and without the session - blocked.
ISSUE:
The progress bar works fine - but IF the user change the window or the current tab - and "forgot" the page open - the countdown stops. I don't know why
THE CODE:
function progress(timeleft, timetotal, $element) {
var progressBarWidth = timeleft * $element.width() / timetotal;
$element.find('div').animate({ width: progressBarWidth }, timeleft == timetotal ? 0 : 1000, "linear");
if(timeleft > 0) {
setTimeout(function() {
progress(timeleft - 1, timetotal, $element);
}, 1000);
}
};
progress(30, 30, $('#progressBar'));
#progressBar {
width: 90%;
margin: 10px auto;
height: 2px;
background-color: #E0E0E0;
}
#progressBar div {
height: 100%;
text-align: right;
padding: 0 0px;
line-height: 2px;
width: 0;
background-color: #FF0000;
box-sizing: border-box;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="progressBar">
<div class="bar"></div>
</div>
JSFIDDLE: https://jsfiddle.net/2tonbd5k
Any idea to solve this?
I'm think I need to change the fixed "timeleft or timetotal" (+3Min) to a "real time" (user access the site at 21:57:00 then the "real time" to reload will be +3 minutes - 22:00:00 PM). If user go out, the animation will stop too - but when he returns the js will correct to the real time. I can update the "time" with ASP - but how I can do this?
** for test purposes timeleft in code is only 30s.

all you need is add this script
if ( document.hidden ) { return; }
the result is here

How Can I Change size of the circles?

I saw a code and i was trying to modify the size of the circles, but i don't know whither i can change it using js or css .Is there any way to change it ?
The full code is from:
https://codepen.io/XTn-25/pen/NWqeBaz
hesr is js code:
/**
* index.js
* - All our useful JS goes here, awesome!
Maruf-Al Bashir Reza
*/
console.log("JavaScript is amazing!");
$(document).ready(function($) {
function animateElements() {
$('.progressbar').each(function() {
var elementPos = $(this).offset().top;
var topOfWindow = $(window).scrollTop();
var percent = $(this).find('.circle').attr('data-percent');
var percentage = parseInt(percent, 10) / parseInt(100, 10);
var animate = $(this).data('animate');
if (elementPos < topOfWindow + $(window).height() - 30 && !animate) {
$(this).data('animate', true);
$(this).find('.circle').circleProgress({
startAngle: -Math.PI / 2,
value: percent / 100,
thickness: 14,
fill: {
color: '#1B58B8'
}
}).on('circle-animation-progress', function(event, progress, stepValue) {
$(this).find('div').text((stepValue * 100).toFixed(1) + "%");
}).stop();
}
});
}
// Show animated elements
animateElements();
$(window).scroll(animateElements);
});

It seems like it's using this as a dependency. So in order to change the circle size, you need to add size property which defaults to 100:
$(this).find('.circle').circleProgress({
startAngle: -Math.PI / 2,
value: percent / 100,
thickness: 14,
fill: {
color: '#1B58B8'
},
size: 300 // <-- here, the size changes the circle radius
})
and in order to stop overlapping the circles, you also need to modify the CSS a little bit by increasing the width of the .progressbar element:
.progressbar {
display: inline-block;
width: 300px;
margin: 25px;
}
So the full example would look like this:
/**
* index.js
* - All our useful JS goes here, awesome!

$(document).ready(function($) {

var percent = $(this).find('.circle').attr('data-percent');
var percentage = parseInt(percent, 10) / parseInt(100, 10);
var animate = $(this).data('animate');
if (elementPos < topOfWindow + $(window).height() - 30 && !animate) {
$(this).data('animate', true);
$(this).find('.circle').circleProgress({
startAngle: -Math.PI / 2,
value: percent / 100,
thickness: 14,
fill: {
color: '#1B58B8'
},
size: 300
}).on('circle-animation-progress', function(event, progress, stepValue) {
$(this).find('div').text((stepValue * 100).toFixed(1) + "%");
}).stop();
}
});
}
// Show animated elements
animateElements();
$(window).scroll(animateElements);

setInterval issue in custom jquery image slider with both auto slide and buttons

I am creating a custom image slider with custom slide effect in jQuery which has both next & previous buttons and also slides automatically with 5 seconds timeout. Although it works nicely in a quick look but sometimes( I dont know exactly when, maybe when I press the buttons or if I leave it open for some time and minimize the window) the iterval bugs and the slides change after 1 second or less. Also when i press the button i tell it to 1) clear iterval 2) change slide 3) set interval again which means that after i change a slide with the button the timer is set to 5 seconds from the start but this is not happening all the times.Here is the code.
$(document).ready(function() {
'use strict';
var $carousel = $('.carousel');
var $nextBtn = $('#next');
var $prevBtn = $('#prev');
var animationSpeed = 1000;
var pause = 5000;
var interval;
function nextSlide() {
$('.carousel__list').animate({
left: '-200%'
}, 500, function() {
$('.carousel__list').css('left', '-100%');
$('.carousel__item').last().after($('.carousel__item').first());
});
}
function prevSlide() {
$('.carousel__list').animate({
left: '0%'
}, 400, function() {
$('.carousel__list').css('left', '-100%');
$('.carousel__item').first().before($('.carousel__item').last());
});
}
function startSlider() {
interval = setInterval(function() {
nextSlide();
}, pause);
}
function stopSlider() {
clearInterval(interval);
}
$carousel.on('mouseenter', stopSlider).on('mouseleave', startSlider);
startSlider();
$nextBtn.on('click', function() {
stopSlider();
nextSlide();
startSlider();
});
$prevBtn.on('click', function() {
stopSlider();
prevSlide();
startSlider();
});

And here is a codepen: https://codepen.io/anon/pen/erpyJj

You are creating more intervals than you think and you don't actually clear each one because you overwrite the interval variable and then you don't a have a reference to the previous intervals, which may still be active.
What you could do is put every interval you create in an array, then when you need to stop all intervals, iterate through that array, clear each interval and empty the array.
// ...
var intervals = [];
// ...
function stopSlider() {
console.log("stopSlider() intervals (Before clear): ", intervals);
intervals.forEach(function(interval) {
clearInterval(interval); // stop one interval
});
intervals = []; // clear the array
console.log("stopSlider() intervals (After clear): ", intervals);
}
Here is your demo with many console logs. You can see that it doesn't matter how much you click on any button, the slider only automatically slides every 5 s.
$(document).ready(function() {
"use strict";
//cache dom elements
var $carousel = $(".carousel");
var $nextBtn = $("#next");
var $prevBtn = $("#prev");
var animationSpeed = 1000;
var pause = 5000;
var intervals = [];
function nextSlide() {
console.log("nextSlide() intervals: ", intervals);
$(".carousel__list").animate({
left: "-200%"
}, 500, function() {
$(".carousel__list").css("left", "-100%");
$(".carousel__item")
.last()
.after($(".carousel__item").first());
});
}
function prevSlide() {
console.log("prevSlide() intervals: ", intervals);
$(".carousel__list").animate({
left: "0%"
}, 400, function() {
$(".carousel__list").css("left", "-100%");
$(".carousel__item")
.first()
.before($(".carousel__item").last());
});
}
function startSlider() {
console.log("startSlider() interval (BEFORE): ", intervals);
var interval = setInterval(function() {
nextSlide();
}, pause);
intervals.push(interval);
console.log("startSlider() interval (AFTER): ", intervals);
}
function stopSlider() {
console.log("stopSlider() intervals (Before clear): ", intervals);
intervals.forEach(function(interval) {
clearInterval(interval); // stop one interval
});
intervals = []; // clear the array
console.log("stopSlider() intervals (After clear): ", intervals);
}
$carousel.on("mouseenter", stopSlider).on("mouseleave", startSlider);
startSlider();
$nextBtn.on("click", function() {
stopSlider();

Background Width jQuery Specification Not Working

I created a web page where the background of my page changes depending on the hour. I want the background image to always be the full width of the page, so I am trying to set it to be 100%, but it doesn't seem to be working. Is there some part of the code that's written incorrectly? Do I need to implement something else?
body {
margin-left: 5%;
margin-right: 5%;
}
#demo {

}

float: left;

font-size: 90px;
margin: 20px;

#weather {

You could try removing the margin attributes on the body tag in your CSS, and set background-size: cover on the body tag there. Then in your changeBackground function, you mightn't need the .width(100%); method, since the width shouldn't change when you swap out the background images?

If you are putting the background image on the body and you have this css property, it won't do.
body {
margin-left: 5%;
margin-right: 5%;
}
Make the property
body {
margin:0;
}

I'm using two different jquery newsticker examples:
The first end at:
<br><br><span id="timer"></span><br><br>
From there it's the second one.
I also added now in the top of my code this variable jQuery132:
<script>var jQuery132 = $.noConflict(true);</script>
How and where to use this variable ?

Here is a nice article regarding jQuery conflicts.
Here is code:
<!-- load jQuery version 1.9.0 -->
<script src="jquery-1.9.0.js" type="text/javascript"></script>
<script type="text/javascript">
var $jQuery1_9 = $.noConflict(true);// Here you must need to pass true
//else it will only free $ variable
//and using jQuery with blow libraries
//cause conflict
</script>
//you must load second library later after initializing
//first instance of version and freeup jQuery keyword
//else jQuery keyword will
//cause conflict it you uplaoded both files.
<!-- load jQuery version 1.10.0 -->
<script src="jquery-1.10.0.js" type="text/javascript"></script>
<script type="text/javascript">
var $jQuery1_10 = $.noConflict(true);
</script>
//so now here $ and jQuery both cannot be used
//using $jQuery1_10 will call version 1.10.0 library code
$jQuery1_10( "div p" ).show();
//using $jQuery1_9 will call version 1.9.0 library code
$jQuery1_9( "div p" ).show();
