Delay random position jQuery

I have some code that displays 4 divs at a random hight at specified distances from the viewport sides, each div appears with a different delay speed and then moves around the page at random.
I want to add a delay to the movement of each div so they don't all start and stop moving at the same time but every time I add ad .delay() it breaks. Any help?
Thanks

How to keep user's scrolling place when resizing div

I wanted to do a cool menu effect for a website I'm working on. I'm having a div act as the the section for the main content. When the user opens the menu, the main content div will resize and move out of the way, revealing the menu. However, when I do this with the code I have written, it always loses my scrolling place on the page. Is there any way to keep my place on the page when it shrinks and also when it expands back again? Below is what I have. Thank you in advance!
function shrinkPage() {
var element = document.getElementById("mock-body");
element.classList.toggle("mock-body-on-burger");
var z = document.getElementById("mock-body-container");
z.classList.toggle("mock-body-container-on-burger");
var x = document.getElementById("body");
x.classList.toggle("body-on-burger");
};
body {
margin: 0;
background:#000;
}
.body-on-burger {
max-width: 100%;
overflow-x:hidden;
}
.mock-body-container{
height:100vh;
}
.mock-body-container-on-burger {
height:100vh;
transform: scale(0.4) translate(130%);
overflow: hidden;
}
.mock-body-size-change{
overflow: scroll;
}
.mock-body {
position:relative;
background: #fff;
margin-left: 50px;
}
.container {
position: fixed;
height:50px;
width:50px;
cursor: pointer;
}
.container #icon {
width: 16px;
height: 8px;
position: relative;
margin: 0px auto 0;
top: 40%;
}
.container #icon .bars {
height: 1px;
background: #fff;
}
.myDiv {
height:500px;
}
.one {
background:red;
}
.two {
background:green;
}
.three {
background:blue;
}

Please take a look at the snippet below. Notice how the overflow property is used.
You have to scroll mock-body-container to keep its scrolling position.
You're scrolling body instead, so when you scale mock-body-container there is nothing to scroll in body and you loose the scrolling position.
function shrinkPage() {
var element = document.getElementById("mock-body");
element.classList.toggle("mock-body-on-burger");
var z = document.getElementById("mock-body-container");
z.classList.toggle("mock-body-container-on-burger");
var x = document.getElementById("body");
x.classList.toggle("body-on-burger");
};
body {
margin: 0;
background:#000;
}
.body-on-burger {
max-width: 100%;
overflow-x:hidden;
}
.mock-body-container{
height:100vh;
overflow:auto;
}
.mock-body-container-on-burger {
height:100vh;
transform: scale(0.4) translate(130%);
}
.mock-body-size-change{
overflow: scroll;
}
.mock-body {
position:relative;
background: #fff;
margin-left: 50px;
}
.container {
position: fixed;
height:50px;
width:50px;
cursor: pointer;
}
.container #icon {
width: 16px;
height: 8px;
position: relative;
margin: 0px auto 0;
top: 40%;
}
.container #icon .bars {
height: 1px;
background: #fff;
}

height:500px;
}
.one {

}

}

Once you know the element that was in focus it should be relatively easy. If you need to find which element was last in focus, you can do that with a scroll function. If you need this as well let me know and I will update my answer.
If you know that #mock-body is the last element in focus, just scroll back to it after the resize.
In this example I've used jQuery as it makes this interaction easier, but this can be done (albeit more verbosely) with vanilla JS as well.
$('html, body').animate({
scrollTop: $('#mock-body').offset().top
}, 0); // If you want the animation to be smoother you can increase 0 to a higher number

A simple way to do it is to remember the position of the document scroll and reapply it when you getting back to "normal" view:
let savedScroll;
function shrinkPage() {
let _s = (el) => document.querySelector(el),
s_ = (d) => !d.classList.contains('body-on-burger'),
x = _s('#body'),
element = _s('#mock-body'),
z = _s('#mock-body-container');
if (s_(x)) {
savedScroll = document.documentElement.scrollTop;
}
element.classList.toggle("mock-body-on-burger");
z.classList.toggle("mock-body-container-on-burger");
x.classList.toggle("body-on-burger");
if (s_(x)) {
document.documentElement.scrollTop = savedScroll;
}
};
Check it out:
let savedScroll;
function shrinkPage() {
let _s = (el) => document.querySelector(el),
s_ = (d) => !d.classList.contains('body-on-burger'),
x = _s('#body'),
element = _s('#mock-body'),
z = _s('#mock-body-container');
if (s_(x)) {
savedScroll = document.documentElement.scrollTop;
}
element.classList.toggle("mock-body-on-burger");
z.classList.toggle("mock-body-container-on-burger");
x.classList.toggle("body-on-burger");
if (s_(x)) {
document.documentElement.scrollTop = savedScroll;
}
};
body {
margin: 0;
background: #000;
}
.body-on-burger {
max-width: 100%;
overflow-x: hidden;
}
.mock-body-container {
height: 100vh;
}
.mock-body-container-on-burger {
height: 100vh;
transform: scale(0.4) translate(130%);
overflow: hidden;
}
.mock-body-size-change {
overflow: scroll;
}
.mock-body {
position: relative;
background: #fff;
margin-left: 50px;
}
.container {
position: fixed;
height: 50px;
width: 50px;
cursor: pointer;
}
.container #icon {
width: 16px;
height: 8px;
position: relative;
margin: 0px auto 0;
top: 40%;
}
.container #icon .bars {
height: 1px;
background: #fff;
}
.myDiv {
height: 500px;
}
.one {
background: red;
}
.two {
background: green;
}
.three {
background: blue;
}
<body id="body">
<div class="menu-activator" onclick="shrinkPage()">
<div class="container usd">
<div id="icon">
<div class="bars first"></div>
</div>
</div>
</div>
<div id="mock-body-container" class="mock-body-container">
<div id="mock-body" class="mock-body">
<div class="myDiv one"></div>
<div class="myDiv two"></div>
<div class="myDiv three"></div>
</div>
</div>
</body>
Legend: _s(el) returns first match of el and s_(d) checks if d has class body-on-burger.

The simple way to do this is to determine the change in height during the resize, and scroll that much.
const heightChange = newHeight - initialHeight;
scrollableDiv.scrollTop = scrollableDiv.scrollTop - heightChange;
In my case I am using a resize method I wrote, so I do this work inside of a window.addEventListener("mousemove", handleResize); when I know the div in actively being resized by the user.
This will still work fine with native html resizable elements, you just need to figure out how/when to listen for resize/drag events accordingly.

Jquery animate() effect doesn't function well

When hover on the first and second element, some element will animate to the left, it works well if hovered with a normal speed, but will crashed if hovered too fast for some times
(the text won't show or the text won't move back to its original place when mouseoff, checkout the figures below).
Any suggestions would be appreciated.
1.text won't show
2.text won't move back to its original place
$(document).ready(function() {
var flag = false;
$(".tab-ico").hover(function() {
var f = $(this);
f.data('timeout', window.setTimeout(function() {
f.find(".tab-text").stop(true, true).animate({
left: "-=64"
}, 300, function() {
flag = true;
});
}, 300));
}, function() {
clearTimeout($(this).data("timeout"));
if (flag === true) {
$(this).find(".tab-text").stop(true, true).animate({

}, 300, function() {
flag = false;

you can use css transition-delay property as follows:
transition-delay: 1s; /* delays for 1 second */
-webkit-transition-delay: 1s; /* for Safari & Chrome */
Find more info here.

I suggest that you use CSS transition, here are two links that will help you make that with less code and using CSS transition

align divs passed the browsers width with a slide in effect

How can I align the following coloured divs next to each other, so that each one is the full width of the browser window (responsive) and only one is display at a time?
http://codepen.io/anon/pen/gpxvjm
HTML:
<div class="content-area">
<div class="p1">Page 1</div>
<div class="p2">Page 2</div>
<div class="p3">Page 3</div>
</div>
<a class="previous-page" href="#">Previous Page</a>
<a class="next-page"href="#">Next Page</a>
CSS:
body {background: grey;}
.p1 {
background: red;
float: left;
width: 100%;
display: inline;
overflow: hidden;
}
.p2 {
background: blue;
float: left;
width: 100%;
display: inline;
overflow: hidden;
}
.p3 {
background: green;
float: left;
width: 100%;
display: inline;
overflow: hidden;
}
.content-area {
width: 100%;
overflow: hidden;
}
Also, when the user selects the previous and next buttons, how can I then push the divs either left or right depending on which anchor link is selected?

I would really recommend slick.js to create the carousel effect you are after.
It is super easy to setup, allows for responsive design, is quite compatible with old IE and has features like arrows and dots built in!
If you want to run your own, i would suggest toggling classes in javascript which leverage css transforms & transitions to ensure maximum performance.
For example,
.page{
width: 100%;
height: 500px;
position: absolute;
top: 0;
transition: .5s;
}
.hide-left{
transform: translateX(-100%);
}
.hide-right{
transform: translateX(100%);
}
Adding browser specific prefixes where required.

This is one of solution, define parent with (number of pages) x 100% width and each child of page 100% / (number of pages) width :
var currentPage = 0;
$('.previous-page').on('click', function() {
currentPage--;
$('.content-area').css('left', (currentPage * -100) + '%');
});
$('.next-page').on('click', function() {
currentPage++;
$('.content-area').css('left', (currentPage * -100) + '%');
});
body {background: grey;}
.content-area div {
float: left;
width: 33.3333%;
display: inline;
overflow: hidden;
}
.p1 {
background: red;
}
.wrap {
width: 100%;
position: relative;
overflow: hidden;
}
.content-area {
width: 300%;
overflow: hidden;
left: 0;
position: relative;
-webkit-transition: left 2s;
transition: left 2s;
}
.p2 {
background: blue;
}
.p3 {
background: green;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="wrap">
<div class="content-area">
<div class="p1">Page 1</div>
<div class="p2">Page 2</div>
<div class="p3">Page 3</div>
</div>
</div>
<a class="previous-page" href="#">Previous Page</a>
<a class="next-page"href="#">Next Page</a>
You can improve the script, i just made it to illustrate the slider.

Here, I've created a jsfiddle here for what I think it is that you want. I've also created a snippet below.
$(document).ready(function () {
for (var i = 0; i < $(".content-area div").length; i++) {
$(".content-area div").eq(i).css({
left: "+=" + parseInt($(".content-area").width() * i, 10)
});
}
});
var currentPage = 0; //0th index
$(".previous-page").click(function () {
changePage(-1);
});
$(".next-page").click(function () {
changePage(1);
});
function changePage(updown) {
if ($(".content-area div")[currentPage + updown]) {
$(".content-area div").animate({
left: "+=" + parseInt($(".content-area").width() * -updown, 10)
},1600);
currentPage += updown;
}
}
body, html {
background: grey;
margin: 0;
padding: 0;
}
.p1 {
background: red;
}
.p2 {
background: blue;
}
.p3 {
background: green;
}
.content-area {
position: absolute;
left:0;
right:0;
top:0;
bottom:0;
overflow: hidden;
}
.content-area div {
position:absolute;
left:0;
width: 100%;
height:100%;
}
.next-page, .previous-page {
z-index:2;
position:fixed;
bottom:5px;
}
.next-page {
right:5px;
}
.previous-page {
left:5px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="content-area">
<div class="p1">Page 1</div>
<div class="p2">Page 2</div>
<div class="p3">Page 3</div>
</div>
<a class="previous-page" href="#">Previous Page</a>
<a class="next-page" href="#">Next Page</a>

Animate multiple elemts from middle to top with jQuery

i'm trying to move divs(actually they are AlwaysVisibleControls) from center-screen to the top of the page after a few seconds.
This is what i have:
$(document).ready(function() {
Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(PageLoaded)
});
var ScrollTopTimeOuts = [];
function PageLoaded(sender, args) {
$('.PanelNotificationBox').click(function () {
$(this).fadeOut('slow', function () {
$(this).remove();
});
});
while (ScrollTopTimeOuts.length != 0) {
clearTimeout(ScrollTopTimeOuts[ScrollTopTimeOuts.length - 1]);
ScrollTopTimeOuts.length--;
}
ScrollTopTimeOuts[ScrollTopTimeOuts.length] = setTimeout(function () {
$('.PanelNotificationBox').animate({ top: 0 }, 'slow');
}, 3000);
}
This works, but the problem is that there can be more than one notification($('.PanelNotificationBox').size()>1). Then they will overlap each other after the animation.
Q: How can i animate elements so that the first element will be on top and the next elements will keep their positions relative to the others?
Edit: After i added the notification-div(s) to a container-div and try to animate that, it won't be animated at all. This is the generated HTML/CSS(note: the outer div is an UpdatePanel):
<div id="ctl00_UpdNotifier"
<div style="top: 0px;" id="ctl00_Notifier1_PnlNotification" class="NotificationContainer">
<div style="left: 292px; top: 398px; display: none; visibility: visible; position: absolute; cursor: pointer; opacity: 1;" id="ctl00_Notifier1_InfoMsg2" class="PanelNotificationBox PanelInfo AutoHide" title="click to close notification">
<span>Test-Notification(Info)</span>
</div>
<div style="left: 292px; top: 463px; visibility: visible; position: absolute; cursor: pointer; opacity: 1;" id="ctl00_Notifier1_ErrorMsg1" class="PanelNotificationBox PanelError" title="click to close notification">
<span>Test-Notification(RMA-Error)</span>
</div>
</div>
</div>
CSS-File:
.PanelNotificationBox
{
visibility:hidden;
z-index:9999;
width: 50%;
font-weight: bold;
font-size:small;
border: 1px solid;
margin: 10px auto;
padding: 20px 20px 20px 60px;
background-repeat: no-repeat;
background-position: 8px center;
box-shadow: 2px 2px 3px #3A4F63;
border-radius: 4px;
}
.PanelInfo {
color:Black;
background-color: InfoBackground;
background-image: url('../images/info-icon.png');
}
.PanelError {
color:White;
background-color: red;
background-image: url('../images/error-icon.png');
}

I suggest to place all your messages in a div, and set this div on abosule position on the top of the page and animate this div that holds all the messages. I think that you can even just place all your element in this div, and they arrange by him self the one afther the other.
<style type="text/css">
.Containerv {
position:absolute;
left:10px;
top:10px;
width:230px;
}
</style>
<div id="ContainerID" class="Container">
<div>First element</div>
<div>Second element</div>
<div>.... next elements</div>
</div>
and your javascript
$(document).ready(function() {
Sys.WebForms.PageRequestManager.getInstance().add_pageLoaded(PageLoaded)
});
var ScrollTopTimeOuts = [];
function PageLoaded(sender, args)
{
// keep this to indivitual close messages
$('.PanelNotificationBox').click(function () {
$(this).fadeOut('slow', function () {
$(this).remove();
});
});
clearTimeout(ScrollTopTimeOuts);
ScrollTopTimeOuts = setTimeout(function () {
$('#ContainerID').animate({ top: 0 }, 'slow');
}, 3000);
}

The approaches from #Yoshi and #Aristos had the disadvatage of breaking the AlwaysVisibleControls js-functionality. Thank you anyway :)
I ended with this solution what is working fine(leaving out the timer part):
var first=$('.PanelNotificationBox:first');
$('.PanelNotificationBox').each(function (index) {
$(this).animate({ top: '-=' + first.offset().top }, 'slow');
});
