Toggle Element Colour Based on Background Colour in JS

I've written some JavaScript code that almost works the way I want it to, but I need some help figuring out how to make it work the way I need it to.
I want to change the colour of a fixed navigation element (hamburger) when it encounters a section with the class of white.Right now this is accomplished by adding a class of darker to that nav element.
What I can't figure out is how to have the darker class removed when I scroll past an element that no longer has the class of white. Any help is much appreciated!
Thanks in advance! :)
Code pen demo
The code is as follows: (Maybe not showing as expected here in SO, better in Codepen)
$(document).ready(function(){
$('#hamburger').click(function(){
$(this).toggleClass('open');
});
});
$(document).ready(function () {
var change = $('.change');
$(window).scroll(function () {
var y = $(this).scrollTop();
var z = $('.white').offset().top;
if (y >= z) {
change.addClass('darker');
}
else {
change.removeClass('darker');
}
});
});

I think this is the javascript code that will do what you want:
$(document).ready(function(){
$('#hamburger').click(function(){
$(this).toggleClass('open');
});
});
$(document).ready(function () {
var change = $('.change');
$(window).scroll(function () {
var top1 = change.offset().top;
var bottom1 = change.offset().top + change.outerHeight(true);
var overlapsWhite = false;
$('.white').each(function() {
var top2 = $(this).offset().top;
var bottom2 = $(this).offset().top + $(this).outerHeight(true);
if (top1 >= top2 && bottom2 >= bottom1){
overlapsWhite = true;
return false;
}
});
if (overlapsWhite) {
change.addClass('darker');
}
else {
change.removeClass('darker');
}
});
});

How to get jQuery to wait until an animation is finished? [duplicate]

This question already has answers here:
How to use jQuery to wait for the end of CSS3 transitions?
(6 answers)
Closed 5 years ago.
I need to wait (prevent) until this animation (flip card) is finished, if you hover again while animation is running it triggers again and restart the animation.
1) I want leave finish the currently animation even you hover again or you hover out. This is what I have tried so far:
if(!$(this).find(".card").is(':animated')){
$(this).find(".card").toggleClass('flipped')
}
And this:
$(":animated").promise().done(function() {
$(this).find(".card").toggleClass('flipped')
});
2) If you re-hover flipped card (blue part) and you leave the cursor inside dont flip it again to the red part while cursor is inside. I tried this canceling setTimeout with clearTimeout but still doesnt work:
$(document).ready(function () {
var funct = 0
$(".container").hover(function () {
clearTimeout(funct);
$(this).find(".card").addClass('flipped')
}, function () {
var val = $(this).find(".card")
var funct = setTimeout(function () {
val.removeClass('flipped')
}, 2000)
})
})
Note: I use setTimeOut function because I need reverse flip card 2 seconds after you hover out and I want keep it.
Here is the working snippet code:
$(document).ready(function () {
$(".container").hover(function(){
$(this).find(".card").toggleClass('flipped')
}, function(){
var val = $(this).find(".card")
setTimeout(function(){
val.toggleClass('flipped')
}, 2000)
})

Run a conditional check first to determine if the trigger class flipped has already been added to the element in question.
This will imply that the animation is still running or currently active (if the class flipped is already present).
if (!$(this).find(".card").hasClass('flipped')) {
$(this).find(".card").toggleClass('flipped')
}
$(document).ready(function() {
$(".container").hover(function() {
if (!$(this).find(".card").hasClass('flipped')) {

Then replace the .toggleClass() method with the .removeClass() method in your setTimeout() function for better "fool-proofing" and more reliable application during intended events - so that this class is never unintentionally added when it should simply be removed.
Edit
To address the issue you've pointed out in the comments, see what the embedded code snippet below demonstrates.
Essentially, a class is added as a flag to check against during specific events at specific times.
$(document).ready(function() {
$('.container').hover(function() {
if (!$(this).find('.card').hasClass('flipped')) {
$(this).find('.card').toggleClass('flipped')
}
$(this).find('.card').addClass('hovered'); /* add class - this will be our flag we'll check against */
}, function() {
var val = $(this).find('.card');
$(this).find('.card').removeClass('hovered'); /* remove class - if we refrain from hovering over again, the condition block below will return true and run the code within */
setTimeout(function() {
if(!val.hasClass('hovered')) {
val.removeClass('flipped')
}
}, 1000);
});
});

CSS How to animate angled lines with skew transitions

I'm looking to incorporate a line that's being drawn that separates into 2 more spreading upwards and downwards by 45 degrees. This is CODEPEN.
CSS:
.connector {
height: 40px;
width: 200px;
border-bottom: 2px solid red;
border-right: 2px solid red;
-moz-transform: skew(-45deg);
-webkit-transform: skew(-45deg);
transform: skew(-45deg);
}

This would work:
.connector {
position: relative;
margin: 100px;
width: 100px;
height: 2px;
background: #f00;
}
.connector:before,
.connector:after {
position: absolute;
left: 100%;
top: 0;
content: '';
width: 100px;
height: 2px;
background: #f00;
transform-origin: 0 100%;
transform: rotate(-45deg);
}
.connector:after {
transform: rotate(45deg);
}
<div class="connector"></div>
Here is an animated version:
.connector {
position: relative;
margin: 100px;
width: 0;
height: 2px;
background: #f00;
animation: draw 1s linear;
animation-fill-mode: forwards;
}
.up,
.down {
position: absolute;
left: 100%;
top: 0;
content: '';
width: 0;
height: 2px;
background: #f00;
transform-origin: 0 100%;
transform: rotate(-45deg);
animation: draw 1s linear;
animation-delay: 1s;
animation-fill-mode: forwards;
}
.down {
transform: rotate(45deg);
}
#keyframes draw {
0% {
width: 0px;
}
100% {
width: 100px;
}
}
<div class="connector">
<div class="up"></div>
<div class="down"></div>
</div>

inserting a text box at top of the page

I have been trying this for a lot of time. How can I add a bigger text box on the top of the page ie it would be outside the div tag of the button which would be clicked
https://jsfiddle.net/Lx3rtLx0/2/
For eg on clicking one of the four emerging images it should display
a text box on the top of the page like the one shown below
I want the code given to arrive on the page on clicking one of the images. I.e. when you click on one of the images(jsfiddle) ..a text box(code given) should appear. on different clicks diff content.
#adbox {
width: 800px;
height: 150px;
border-width: 0;
border-color: red;
background-color:grey;
}
#adbox .adbox1 {
width: 200px;
height: 50px;
border-width: 0;
border-color: red;
float:left;
background-color:lightblue;
margin:0px 0px 0px 300px;
}
#adbox .adbox2 {
width: 200px;
height: 50px;
border-width: 0;
border-color: red;
float:right;
background-color:red;
margin:0px 60px 0px 0px;
}
.clear{
clear:both;
}
<!DOCTYPE html>
<html>
<head>
<title>BOX</title>
</head>
<body>
<div align=center><div id="adbox">
<h1><br> xyz sent you a hug</br></h1>
<div class="adbox1">
<br>Send a Hug Back</br>
</div>
<div class="adbox2">
<br>Ack | Dis</br>
</div>
<div class="clear"/>
</div></div>
</body>
</html>

Not super clear on your question, do you need to add an input to the jsfiddle in your question? or the code you have listed in your question? If it is in the jsfiddle, just add this to the top of the code:
<body>
<section id="header">
<div class="inner">
<div>
<input type="text" style="position:absolute; width:300px;" />
</div>
Otherwise, the attribute position:absolute should work out for you, if it isn't in the right place, add attributes like top:0; left:0, and that will put your input in the top left despite anything else in your code.

Simple, on your click button add the code as in https://jsfiddle.net/Lx3rtLx0/6/
var input = document.createElement('input'); // if you want label just change inpput to label
input.type='text';
input.value = 'hugs or whatever';
document.body.insertBefore(input, document.body.firstChild);
So the full JS become
$(document).ready(function() {
$(".trigger").click(function() {
$(".menu").toggleClass("active");
var input = document.createElement('input'); // if you want label just change inpput to label
input.type='text';
input.value = 'hugs or whatever';
document.body.insertBefore(input, document.body.firstChild);
});
});

You can use a data- attribute on your clickable divs to link them with a specific element (a textbox in this case). For example:
<div class="btn btn-icon" title="Send a hug to Mohammed" data-adbox="adbox1">
In the click handler, we can retreive this attribute and show the element with id adbox1.
Full example:
$(document).ready(function() {
$(".trigger").click(function() {
$(".menu").toggleClass("active");
});
$(".btn.btn-icon").click(function() {
$('.adbox').hide();
$('#' + $(this).data('adbox')).show();
});
$('.adbox').click(function() {
$(this).hide();
});
});

Grey out background while page loading

On my page I've got an animated image which runs when the page is busy loading. I've managed to get it to show when the page is busy and stop when the page is not busy. I'm struggling to get the page to grey out while this progress image runs... I've read about a div overlay, but it's not working. How do I do this? I'm new to javascript
This is what I've done:
In my asp.net I've got the following:
<div class="loading" align="center">
<div class="main">
<div class="small1">
<div class="small ball smallball1"></div>
<div class="small ball smallball2"></div>
<div class="small ball smallball3"></div>
<div class="small ball smallball4"></div>
</div>
<div class="small2">
<div class="small ball smallball5"></div>
<div class="small ball smallball6"></div>
<div class="small ball smallball7"></div>
<div class="small ball smallball8"></div>
</div>
<div class="bigcon">
<div class="big ball"></div>
</div>
</div>
</div>
My javascript is as follows:
<script type="text/javascript">
function ShowProgress() {
setTimeout(function () {
var loading = $(".loading");
loading.show();
$('#overlay').css({
'display': 'block',
opacity: 0.7,
'width': $(document).width(),
'height': $(document).height()
});
$('body').css({'overflow':'hidden'});
$('#loading').css({ 'display': 'block' }).click(function () {
$(this).css('display', 'none');
$('#screen').css('display', 'none')
});
}, 200);
$('#main').dialog({ modal: true });
}
$('form').live("submit", function () {
ShowProgress();
});
</script>
And my css looks like this:
body {
padding: 0px;
height:100%;
background-color:#EBEBEB;
filter:alpha(opacity=70);
opacity:0.7;
background-color: #002031;
}
.main {
background-color:#EBEBEB;
filter:alpha(opacity=70);
opacity:0.7;
}

}
#keyframes bigcon {

transform-origin: center;
transform: translate(-50%, -50%) rotate(45deg);
}
100% {

transform: translate(-50%, -50%) rotate(405deg);
}
}
#keyframes small {

15% {

}
25%{

background-color: #46b9ff;
}
100%{
transform: scale(1);
background-color: #46b9ff;
}
}
#loading
{
font-family: Arial;
font-size: 10pt;
border: 0px ;
display: none;
background-color: White;
z-index: 999;
}
What am I doing wrong? Any help will be greatly appreciated

Try this:
CSS
.main:before{
position: absolute;
content:"";
width: 100%;
background: #EBEBEB;
height: 100%;
left:0;
z-index:-1;
}
