Can i get help understanding a changing div section with a background image and gradient filter and using click function javascript to change it?

I have a div section with a background image with a gradient cover and some text on. I want to control changing this with a java script button. When its clicked it should remove the gradient and show a new div section with different background image no gradient and text. The JQuery underneath is supposed to check whether the first div is showing. and when clicked it should hide the original div and replace it with the new one. I cannot seem to get it working. any help would be appreciated.
/*
jQuery event that triggers when the button is pressed
# is an ID jQuery selector, usage:#anyElementId
*/
$('btnClick').on('click',function(){
/*
In CSS, you can check if an element is visible by checking if the property display value is different from none, because if it's value is none, it will not be visible
*/
if($('call-to-section').css('display')!='none'){
/*
So, if div call-to-section is visible, the condition will be true
*/
$('call-to-section2').show().siblings('div').hide();
}else if($('#call-to-section2').css('display')!='none'){
/*
Condition to check if call-to-section2 is visible
*/
$('call-to-section').show().siblings('div').hide();
/*
If it is, it will show call-to-section and right after that will search for it siblings and hide them with .siblings('div').hide();
*/
}
});

I had corrected and obtained the desired result, There was following error in codes written.
1) Both Div element has the same id #call-to, which is actually not required if required for some other purpose please have a separate id for all Div.
2)both Button element also have the same ID #btnClick, change it as #btnClick and #btnClick1
I think id can not be the same for two elements. Read the MDN Web Docs https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/id
Complete Code is available in my Codepen https://codepen.io/sanjayism/full/ExVdKpv
$(document).ready(function () {

if ($(".call-to-section").css("display") == "block") {

show one div and hide the rest onclick

I'm trying to get images to show in the red portions and to stay within the content div, but any time I add images, the layout breaks. I would really appreciate some help with these two things I want to achieve and thank you in advance:
1.) keep images constrained to and auto resizable within the (red) content div
2.) hide the images when the section is "shut" onclick.
HTML:
<div class="section">
<div class="bookmark">↑ ten ↔ sion ↓</div>
<div class="content"><p></p>
<!-- <div class="space"></div> -->
<!-- <img class="fit" src="images/ziptiesmall.png">
<img class="fit" src="images/ziptiesmall2.png">
<img class="fit" src="images/ziptiesmall3.png"> -->
</div>
</div>
the JavaScript:
var sections = document.querySelectorAll(".section")
sections.forEach(function(section) {
section.addEventListener("click", expandSection);
})
function expandSection(event) {
let section = (event.target.classList.contains("section")) ? event.target : event.target.parentNode;
sections.forEach(function(section) {
section.classList.remove("open")
})
section.classList.add("open");
}

I just added this class to the rest of the divs which didnt have any images on them, hence the reason for them to show the red content div. Remove the 100%, the image text in between every column as well and create ids for every column and add background image to them and you are good to go :).
.content.bg.zip {
margin-left: 40px;
/* width: 100%; */
background-color: #000;
background-image: url(images/ziptiepattern.png);
background-repeat: repeat;
}

Scroll effect to change opacity of each new div element

I am new to website design and have a question I'd like to ask. I have tried to use velocity.js to achieve this with failure. I am sure there is a rather simple css solution for what i want. I just want the previous div to "fade" and the new div that's scrolled to, to fade in with greater opacity. Open to any jQuery examples as well.
Here is my code for the section in question:
html:
<section id="services">
<h2 class="pb-5">Services We Offer</h2>
<div id="service1">
<h2>Service 1</h2>
</div>
<div id="service2">
<h2>Service 2</h2>
</div>
<div id="service3">
<h2>Service 3</h2>
</div>
</section>
css:
#services{
}
#service1{
height: 100vh;
background-color: rgb(44, 49, 90);
}
#service2{
height: 100vh;
background-color: #267481;
}
#service3{
height: 100vh;
background-color: #373f24;
}

I am sure there is a rather simple css solution for what i want
Unfortunately, that is not the case. CSS can perform animations, but if scrolling is involved in any way, JS is required.
You could use something like animate.css to control your CSS animations and then use wow.js to make them load on scroll.

As before stated by other answers and comments you cannot manipulate the scroll event in css alone but here is a simple jquery example that may help you. You can add and remove classes on scroll and you can add an animation to the css to control the opacity of your div.
$(window).on("scroll", function(){
var scrollTop = $(this).scrollTop();
$('.scrollDiv').each(function(){
var el = $(this);
var offsetTop = el.offset().top;
if(scrollTop > offsetTop){
el.addClass("scrolled");
}else{
el.removeClass("scrolled");
}
});
});
.scrollDiv{
height:100vh;
transition:opacity 500ms ease-in-out;
opacity:0.2;
}
.scrollDiv.scrolled{
opacity:1;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="scrollDiv" style="background:green;"></div>
<div class="scrollDiv" style="background:red;"></div>
<div class="scrollDiv" style="background:blue;"></div>
<div class="scrollDiv" style="background:yellow;"></div>

Cannot get push menu inline with Bootstrap

I'm using Bootstrap as UI framework, what I'm trying to do is make a push menu on the left. Actually, I almost achieve this result, but there are some bugs on the system. In particular, I'm not able to get the menu inline. See the code for more details:
HTML
<div id="calendar-wrapper">
<div class="container-fluid">
<div class="row">
<div id="resource-bar" class="sidenav col-sm-2">
<h4>Resource</h4>
<div class="input-group">
<input type="text" placeholder="Search resource"
class="form-control resource-filter"/>
<span class="input-group-btn">
<button class="clear btn btn-default clean-resource btn-danger" type="button">
<span class="glyphicon glyphicon-remove"></span>
</button>
</span>
</div>
<div id="popover-content" hidden></div>
</div>
<div id="calendar-container" class="col-sm-10">
<div id="calendar" class="well"></div>
</div>
</div>
</div>
</div>
<br><br><br>
<button type="button" id="show" >Show</button>
<button type="button" id="hide" >Hide</button>
Note that the html above is adapted for a fiddle example.
CSS
.sidenav
{
background-color: azure;
height: 100%;
width: 0;
z-index: 1;
top: 0;
left: 0;
overflow-x: hidden;
transition: 0.5s;
}
#calendar-container
{
background-color: whitesmoke;
transition: margin-left .5s;
padding: 16px;
}
JS
$(document).ready(function()
{
var resourceContainer = $('#resource-bar');
var calendarContainer = $('#calendar-container');
$('#show').click(function()
{
resourceContainer.css('width', '250px');
calendarContainer.css('margin-left', '250px');
});
$('#hide').click(function()
{
resourceContainer.css('width', '0px');
calendarContainer.css('margin-left', '0px');
});
})
The result when the menu on the left is closed:
Seems that both divs are inline, the problem occurs when I press show button and the menu appears:
BUG actually noticed:
When the menu is opened I get the divs in two line instead of one row
Adding the class col-sm-2 to resource-bar the overflow-x: hidden; doesn't working, in fact, seems that the menu is visible when it should be closed.
col-sm-2 does not go in another line when the minimum resolution of the screen doesn't have enough space in width.
Someone could help me to fix this issues? Thanks. JSFIDDLE.

Edited to another workaround which wouldn't affect bootstrap grid:
With this setup sidebar would be absolute, since it's out of viewport and you set it to a fixed width (250px), using the grid wouldn't be necessary.
Visible input will not overflow once sidebar shows.
Raised buttons above sidebar.
Note the HTML structure was tweaked.
$(document).ready(function() {
var resourceContainer = $('#resource-bar');
var calendarContainer = $('#calendar-container');
$('#show').click(function() {
resourceContainer.css('width', '250px');
calendarContainer.css('margin-left', '250px');
});
$('#hide').click(function() {
resourceContainer.css('width', '0px');
calendarContainer.css('margin-left', '0px');
});
})
div.sidenav {
background-color: azure;
height: 100%;
width: 0;
z-index: 1;
top: 0;
left: 0;
overflow-x: hidden;
transition: 0.5s;
/* added absolute to sidenav since it will have fixed width anyways */
position: absolute;
}
#calendar-container {
background-color: whitesmoke;
transition: margin-left .5s;
padding: 16px;
/* this is just to vertically align with sidebar input */
padding-top: 36px;
}
button {
position: relative;
z-index: 2;
}

You're issue lies with the mix of bootstrap and your own JavaScript generated style. It seems you already have knowledge of the Bootstrap Grid layout, but to reinforce, https://v4-alpha.getbootstrap.com/layout/grid/ will tell you that there are 12 columns in a row.
Each column is styled by Bootstrap to a set width with set margins in between. You've have all 12 columns filled up in your row. As you add an additional margin to your already-filled-up calendarContainer column, it will pop out of the row.
Therefore, the easiest way to achieve what you want without affecting any other styles is too make your column smaller and reduce the amount of 'margin-left' you push on the column like so https://jsfiddle.net/Zeenglishking/DTcHh/28837/
<div id="calendar-container" class="col-sm-8">
<div id="calendar" class="well"></div>
</div>
$('#show').click(function()
{
resourceContainer.css('width', '250px');
calendarContainer.css('margin-left', '50px');
});
Also, as you say "seems infact that the menu is even visible also when is closed.", the menu is indeed visible. This is again down to the fact of the bootstrap styling of the grid-layout. If you can figure out what styles are creating this issue (F12), you can override them using "something:!important". https://css-tricks.com/snippets/css/style-override-technique/ . Otherwise, find another way. If you mess around with css positioning elements too much, it's easy to get lost and jumbled with the rest of your code.
EDIT (in regard to comment):
What needs to be used in addition to this is 'col-xs-**' with a smaller size column, allowing for a responsive design and for it to work on the smaller viewports such as the one in JSFiddle. I have updated my fiddle to include
col-xs-1
and
col-xs-4
on resource-bar and calendar-container respectively. This will change the size of the column, upon resize of the screen/viewport to ensure it doesn't drop down on extra-small viewports. More info at http://getbootstrap.com/css/#grid-options
Upon using Bootstrap framework you almost acquire yourself to a certain standard. Shortcuts in fixing this can cause problems with other elements. You're probably best to read more into it before chucking random positioning in to fix certain elements on a page.

Interactions with Background being blocked by Div over the background

I am using Particles.js on the background. I have div layer over the canvas which contains text and images.
This div blocks the interactions with the background killing the experience. Is there a way to make sure the div allows the interactions through it with the background. Above and below the Div the interactions work well as the content is vertically centered.
Demo Link

I see this css in your code. ( line no. 19)
#hero-unit .particles-js-canvas-el {
z-index: -1 !important;
}
Change it to
#hero-unit .particles-js-canvas-el {
z-index: 1 !important;
}
and
#hero-unit #hero-wrapper {
z-index: 1!important;
}
FIX to make the the interaction through the text or next to it
wrap the divs in seperate .col-md-9 rows
<div class="row">
<!-- first row -->
<div class="col-md-9">
<img class="hero-logo hidden-xs" src="http://creo.mink7.com/wp-content/themes/creo/images/logo-home.png" alt="">
<h1 class="head">Together we can Make a universe of smart innovations for a Better tomorrow</h1>
</div>
<!-- second row -->
<div class="col-md-9 newsletter">
<div id="frontpage-mailchimp">
<h4>Join the Community of Makers</h4>
<!-- MailChimp for WordPress v3.0.10 - https://wordpress.org/plugins/mailchimp-for-wp/ -->
<form id="mc4wp-form-1" class="mc4wp-form mc4wp-form-114" method="post" data-id="114" data-name="Join us in making things better">
<!-- mailchimp stuffs -->
</form>
</div>
</div>
</div>
and finally, this css
#hero-wrapper .col-md-9{
z-index: 1; // reduce the default z-index for div
}
#hero-wrapper .col-md-9.newsletter{
z-index: 9999; // increase the z-index for newletter div only
}
