Fluid Box jQuery plugin not working - javascript

Can someone please tell me why my fluid box isn't working for my photo. I've followed all of the instructions to create the code for the fluidbox, but my photo doesn't show up on the webpage. But when you click on where it is supposed to be on the webpage, it takes you to another page that has my photo in it. Here is my codes:

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

Html into wordpress theme

I need to make a fixed bottom footer to my WordPress web, with some buttons including js with a popover. I've Pillar Theme and I only need to make this change. I need to put it into my footer.php. But when I try, nothing works. I do not know if this is the best way to do that. Here is the code that I do for the footer:

You can try Sticky footer with jQuery. Add this code in your js file.
var $ = jQuery.noConflict();
jQuery(document).ready(function($){
/* sticky footer function */
StickyFooter()
});
/* Script on resize */
jQuery(window).resize(function($) {
/* sticky footer function */
StickyFooter();
});
/* Script on load
----------------------------------*/
jQuery(window).load(function($) {
/* sticky footer function */
StickyFooter();
});
/* Sticky Footer Function */
function StickyFooter(){
var Stickyfooter = jQuery( 'footer' ).outerHeight()
jQuery('#wrapper').css('margin-bottom',-Stickyfooter) /* Here #wrapper is your main <div> of <body> */
jQuery('#wrapper').css('padding-bottom',Stickyfooter)
}

Animating back and forth based on scroll position

I have created a small demo of two boxes animating in and out based on scroll position. But this isn't exactly what I want to achieve. What I want is for the boxes to animate based on scroll position not just transition in and out when a certain point is reached.
For example the scrolling should control the animation so if you scroll down the boxes will animate in, if you scroll up they will animate out. If you stop scrolling mid animation the animation will stop. If you reverse the scroll position the animation will reverse. So the animation only happens as you scroll.
I hope that is clear enough for you to understand. I will try provide a link to what I am trying to achieve. But for now here's my demo just using a transition to animate the boxes.
jQuery(document).ready(function($){
var scroll_pos = $(window).scrollTop();
var box = $('#container').offset().top - 200;
$(window).on('scroll', function(){
scroll_pos = $(window).scrollTop();
$('p').html(scroll_pos);
if(scroll_pos >= box){
$('#left').addClass('animate');
$('#right').addClass('animate');
}else{
$('#left').removeClass('animate');
$('#right').removeClass('animate');
}
});
});
#container{
width: 600px;
height: 300px;
margin: 1000px auto;
overflow: hidden;
font-size: 0;
}
#left{
width: 55%;
height: 300px;
background-color: blue;
display: inline-block;
transform: translateX(-100%);
transition: all 0.5s;
}
#right{
width: 45%;
height: 300px;
background-color: yellow;
display: inline-block;
transform: translateX(100%);
transition: all 0.5s;
}
#left.animate{
transform: translateX(0%);
}
#right.animate{
transform: translateX(0%);
}
p{
position: fixed;
top: 0;
left: 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<p></p>
<div id="container">
<div id="left"></div>
<div id="right"></div>
</div>
Here's an example of what I want to achieve. As you can see the scroll controls the animation of the fidget spinner https://ampbyexample.com/visual_effects/basics_of_scrollbound_effects/

Based on this answer you could do someting like:
/**

* http://stackoverflow.com/a/26831113/383904
* Returns a callback function with an argument holding
* the current amount of px an element is visible in viewport
* (The min returned value is 0 (element outside of viewport)
*/
;(function($, win) {
$.fn.inViewport = function(cb) {
return this.each(function(i,el) {
function visPx(){
var elH = $(el).outerHeight(),
H = $(win).height(),
r = el.getBoundingClientRect(), t=r.top, b=r.bottom;
return cb.call(el, Math.max(0, t>0? Math.min(elH, H-t) : Math.min(b, H)));
}
visPx();
$(win).on("resize scroll", visPx);
});
};
}(jQuery, window));
// Now our stuff:
var $container = $("#container");
var $left = $("#left");
var $right = $("#right");
$container.inViewport(function( px ) {
var v = 1 - px / $container.height(); // Value from 1.0 to 0.0 and v.versa
$("p").text(v);
$left.css({transform: `translateX(${ -v * 100 }%)`});
$right.css({transform: `translateX(${ v * 100 }%)`});
});
body {
height: 500vh;
}
#container {
position: relative;
margin: 0 auto;
top: 200vh;
overflow: hidden;
width: 60vw;
height: 60vh;
}
#left,
#right {
width: 50%;
height: 100%;
float: left;
}
#left {
background-color: blue;
transform: translateX(-100%);
}
#right {
background-color: yellow;
transform: translateX(100%);
}
p {position: fixed; top:0; left: 0;}

Slight background zoom on DOM load?

How to reproduce the effect on this website :
https://shop.stripe.com/
I mean waiting for the DOM to fully load before showing anything, and then having the background image zooming out for 1s. Pretty cool.

It's done using different transition and transforms together. Demo: http://jsfiddle.net/lotusgodkk/eHAuh/2/
Key is to add/remove classes in document.ready
HTML:
<div id="DIV_1" class="scaled"></div>
JS:
$(document).ready(function () {
$('#DIV_1').attr('class', 'animatable');
setTimeout(function () {
$('#DIV_1').removeClass('animatable');
}, 1000)
});
CSS:
#DIV_1 {
background-position: 50% 50%;
bottom: 0px;
height: 472px;
left: 0px;
position: absolute;
right: 0px;
top: 0px;
width: 600px;
z-index: 1;
background: rgba(0, 0, 0, 0) url(https://shop.stripe.com/assets/images/showcase/thairu-kat.jpg) no-repeat scroll 50% 50% / cover padding-box border-box;
font: normal normal normal 16px/normal Helvetica, Arial, sans-serif;
zoom:1.1;
background-size:cover;
}
/*#DIV_1*/
.animatable {
-webkit-transition:all 750ms ease-out;
transition:all 750ms ease-out;
}
.scaled {
-webkit-transform:scale(1.02);
transform:scale(1.02);
}

You can also do it easily with pure javascript:
css:
#blackdiv { background: black; color: white; position: fixed; width: 100%; height: 100%; }
html:
<div id="blackdiv"></div>
<div>page content</div>
js:
window.onload = function(){
var blackdiv = document.getElementById('blackdiv');
blackdiv.style.opacity = 1;
doIt();
};
var doIt = function(){
if( blackdiv.style.opacity > 0 ){
console.log(blackdiv.style.opacity);
blackdiv.style.opacity -= .1;
setTimeout("doIt()", 100);
}
}

Parallax Curtain Reveal Effect with jQuery and CSS3

It is really difficult to explain what kind of effect I mean. But let me try. :)
When you scroll down one DIV with text Block moves over a fixed background DIV with a background image. Now when the DIV on top leave the bottom area and moves to the top of the viewport you can seen the half (and later the full) new background image. But the Background Images are not moving, they are fixed. Only the Page Content with Text Blocks moves when you scroll down.
If you still see a question mark then take a look at this website, there you can see the concept in use.
So my question is how can I recreate this effect only with CSS3 and jQuery (Without YUI etc.)?
I don't really understand the logic that is needed for this to work. How do I need to animate the DIVs and where should I place them in the HTML Document.
Below you find some tests I did (But they don't work)

});
$(function(){
$(window).bind({scroll: Scroll, touchmove: Scroll});
});
function Scroll(){
// var op = (window.pageYOffset-$(window).innerHeight()-44-356);
// $("div.pageContentBackground").css("bottom", + op);
var scrollTop = $(window).scrollTop();
var pageYDoc = 1300;
var factor = 0.8;
var pageYViewport = pageYDoc - scrollTop;
var imageY = -1 * parseInt(pageYViewport * factor);
//var tr = -200; // You'd need to calculate this value
/**$('div.red').css("-webkit-transform", "translate3d(0, " + tr + "px, 0)");
*/
//var offset = total + $(window).scrollTop()+400;
$('div.red').css({'-webkit-transform': 'translate3d(0, '+ imageY + '%, 0)'});

This is my try: http://codepen.io/rafaelcastrocouto/pen/bCxAd
Although there are lots of differences in the sites, they are still kinda alike.
Notice that my parallax only woks on big screens.
The JS is pretty small:
var lastScrollTop = 0;
var backgroundImages = $('.backgroundImage');
$(window).scroll(function(e){
var st = $(this).scrollTop();
var ah = $(this).height();
backgroundImages.each(function(i){
var img = $(this);
var pos = img.position().top;
var hei = img.height();
if ((st + ah) > pos && st < (pos + hei)){
var p = ((pos - st)/ah) + 0.25;
if(i == 1) console.log(p);
img.css('background-position', '50%'+(p*100)+'%');
}
});
lastScrollTop = st;
});
$(window).scroll();
