my pop up window is opened the top of page

my pop up window is opened the top of page - javascript

enter image description hereenter image description hereI created a webpage by using html css and javascript. In home page, I added a pop up contact button and form, it is working but pop up window is opened at the top of page. Home page is like one page you scroll. I added the button to the footer but form is opened close to header. I want to it to open while user see the end of the page. I hope I can clear the problem.
https://github.com/ipeksaygut/website in this link there are HTML- CSS-JS files of only home page.
I am really beginner, I really do not understand the problem. Thanks for helps!
-If something need let me know to sahre to clear problem!
Window is seen as the picture but ı want to see it at the end of page I added photo of window how it is seen and where ı want to see it.

Hi Ipek Saygut!
I put together this code that will give you an idea of what was going on with your css. I have modified the .popUp class in order to fix this issue. Please be aware that you will need to read more on HTML and CSS best practices. Please have a look at this article to get you started in the amazing world of HTML and CSS, don't worry, it takes practice but you will master it soon. HTML & CSS Best Practices.
I certainly hope this code helps, have a good time coding, fellow!
let btn = document.querySelector("button");
let cont = document.querySelector(".popUp");
btn.addEventListener('click', function(){
cont.id = "show";
});
cont.addEventListener('click', function(e){
if(e.target == this){
this.id = "hidden";}
e.preventDefault;

This is likely because your webpage is not responsive. An easy fix is to always use percentages instead of specific pixels to position items.
eg top: 5% instead of top: 15px

I think it's because you have to use media queries to make your website responsive on all devices.
Check it out here:
https://developer.mozilla.org/en-US/docs/Learn/CSS/CSS_layout/Media_queries
Another tip is not to use only pixels as a unit of measurement, also use 'em', 'rem', vw (for the font) and '%'
Check it out here too:
https://www.w3schools.com/cssref/css_units.asp

There's a couple of random things in your css that I don't know why they're there. max-width: 2000px, why is this 2000 pixels, it would be way too much for most phones and screens (perhaps there's a reason like the player map being large, I dunno). overflow: hidden, why is there an overflow on a h1 tag. border-width: 100%, why are you setting border widths to 100%. margin: 0 auto why is there a margin auto on a 2000px wide container, it'll never be the center of anything. position: relative, why is everything relative. There's a bunch of random CSS that I don't know what it's doing or why it's there (it shouldn't be).
Along with that you shouldn't ever use pixels for fonts, it won't scale on a mobile phone so your text (and containers containing text) will get messed up. Use font-size: 100% on the html container and then use font-size: 1rem // or 1.2 or 1.4 on anything else so you scale everything according to root.
Along with that you've used pixels everywhere to define borders/tops/alignment, which will almost never work out (unless you're just lucky). You should be using flex for page layout and pixels if you want to define specific containers. You've not shown body and the main page CSS but from container I can see you've not used that. You should have:
body {
display: flex;
flex-flow: column nowrap;
min-height: 100vh;
margin: 0;
}
.container {
flex: 1 1 auto;
display: flex;
flex-flow: column nowrap;
}
Or something similar for your page layout. You don't need any #media stuff for that because flex will work correctly across all devices.

fixing a mobile menu and logo as header for smaller screens

I have a side navigation menu for bigger screens in this file. I want to create a navigation bar for mobile phones and smaller screens below 1024px width. I have tried making the mobile navbar hidden for bigger screens and it just acts up. I need some here is a link to my page
I will want it to look like this
I got the inspiration of the page from link and they were able to make it responsive.
var slideIndex = 0;
var slides = document.getElementsByClassName("home-page-slides");
showSlides();
function showSlides() {
var slideLength = slides.length;
// Fade in the slide
setTimeout(function() {
if (slideIndex == slideLength) {
slideIndex = 0;
}
slides[slideIndex].classList.add("fadeIn");
}, 10);
//Fade out the SLide
setTimeout(function() {
if (slideIndex == slideLength) {
slideIndex = 0;
}
slides[slideIndex].classList.remove("fadeIn");
}, 3980);
slideIndex++;
setTimeout(showSlides, 4000);
}

Scrolldown function

I'm creating a single page mock gym website and i'm using a scroll down function on the nav bar buttons to the relevant sections. I'm also trying to use it on a link in the 'classes' section of the page to scroll down to the contact section of the page. However, when after putting in the js code it takes me to the top of the page instead. the error i'm getting in the console is : Cannot read property 'addEventListener' of null but i don't understand how to fix the problem from similar issues on stackoverflow. Below is the code and the section i'm talking about is the first card in the classes title 'spin' which a 'call or email to book now' link. I would be greatful for any help :)

var classesHeading = document.querySelector('.classes-header');
var ptBtn = document.querySelector('.pt-button');
var ptSection = document.querySelector('.pt-section');
var contactBtn = document.querySelector('.contact-button');
var contactSection = document.querySelector('.contact-section');
var cobBtn = document.querySelector('contactBtn');
aboutBtn.addEventListener('click', function(){
smoothScroll('.about-section', 1000);
});
aboutSection.addEventListener('click', function(){
smoothScroll('.about-button', 1000);
});
classesBtn.addEventListener('click', function(){
smoothScroll('.classes-header', 1000);
});
classesHeading.addEventListener('click', function(){
smoothScroll('.classes-button', 1000);
});
ptBtn.addEventListener('click', function(){
smoothScroll('.pt-section', 1000);

ptSection.addEventListener('click', function(){

});
contactSection.addEventListener('click', function(){
smoothScroll('.contact-button', 1000);
});
cobBtn.addEventListener('click', function(){
smoothScroll('.contact-section', 1000);
});

var cobBtn = document.querySelector('contactBtn');
should be
var cobBtn = document.querySelector('.contactBtn');
because "contactBtn" is a class name, I don't know about your code but I think you then add an event listener to that codeBtn element, which was returning null
in your case because it can't find an element with the tag name "contactBtn"
The Document method querySelector() returns the first Element within the document that matches the specified selector, or group of selectors. If no matches are found, null is returned.

How can I display the thumbnail image and open modal on click using JavaScript

I have hundreds of html-based journal articles that contain html snippets like the example below to reference images:
<div class="fig panel" style="display: float; clear: both">
<a id="de8adf66-3683-c412-3cd6-45bc686a4ebe"><!-- named anchor --></a>
<h5 class="label">Innovation attributes</h5>
<div class="caption">
<p class="first" id="e5a7d435-9a86-3b8e-8a85-5835cdfa4a67">
<i>Adams, 2003.</i>
</p>
</div>
<a id="ID0EHD" href="https://journal.emergentpublications.com/wp-content/uploads/2015/11/de8adf66-3683-c412-3cd6-45bc686a4ebe-300x235.png">
<div class="long-desc" />
<a target="xrefwindow" href="https://journal.emergentpublications.com/wp-content/uploads/2015/11/de8adf66-3683-c412-3cd6-45bc686a4ebe.png" id="ID0ELD">https://journal.emergentpublications.com/wp-content/uploads/2015/11/de8adf66-3683-c412-3cd6-45bc686a4ebe.png</a>
<div class="permissions">
<p class="copyright" />
<p class="copyright">
<span class="generated">Copyright</span>
</p>
<div class="license">
<p class="first" id="ID0ESD" />
</div>
</div>
</a>
</div>
On document ready, using JavaScript and CSS3 how can I show the thumbnail image contained in the first 'a' tag, along with the contents of the 'long-desc' and 'permissions' divs beneath... and then when the thumbnail is clicked, open the image in the second (daughter) 'a' tag in a modal that fills the screen (and has a close button)?

Check this out. You can edit styles as you need for your purpose. It is just a sketch.
document.addEventListener('DOMContentLoaded', function() {
let thumbnail = document.querySelector('.thumbnail');
let close = document.querySelector('.modal-close');
let overlay = document.querySelector('.overlay');
thumbnail.addEventListener('click', function(e) {
e.preventDefault();
overlay.classList.add('visible')
});
close.addEventListener('click', function(e) {
e.preventDefault();
overlay.classList.remove('visible')
});
});
.thumbnail-image {
border: 3px solid #BBB;
border-radius: 4px;
}
.overlay {
display: none;
position: fixed;
top: 0;
left: 0;
height: 100%;
width: 100%;
background-color: rgba(0, 0, 0, 0.3);
}
.overlay.visible{
display:block;
}
.modal-wrapper {
position: relative;
height: 100%;
width: 100%;
}
.modal-image {
height: calc(100vh / 1.28);
width: 100vh;
margin: auto;
}
.modal-image>img {
max-width: 100%;
}
.modal-close {
position: absolute;
top: 10px;
right: 10px;
padding: 5px;
border: 2px solid #444;
background: #bbb;
cursor: pointer;
}
<div class="fig panel" style="display: float; clear: both">

How to scroll up a div when hovering over another element

I have an absolute div that is behind my footer. When I hover over another element (#snapchat) I want that absolute div to scroll up from behind the footer and stop above it where it can be seen. How would I do this?
.snapcode-footer {
position: absolute;
padding-top: 20px;
text-align: center;
left: 0;
right: 0;
}
.sub-sub-footer {
position: relative;
z-index: 1;
background-color: #F7F7F7;
padding-top: 35px;
padding-bottom: 20px;
}
.sub-footer {
position: relative;
z-index: 1;
background-color: #edeeef;
margin-top: 0px;
}
<div class="snapcode-footer">
<img src="https://wumbo.com/wp-content/uploads/2016/11/snapcode.png" width="250px" height="auto" alt="Scan to add us on Snapchat!">
</div>
<div class="sub-sub-footer">
<ul class="social-footer">
<li id="twitter"><img src="/wp-content/uploads/2016/11/Twitter-color.png" alt="Follow us on Twitter #wumbo"/></li>
<li id="snapchat"><img src="/wp-content/uploads/2016/11/Snapchat-color.png" alt="Follow us on Snapchat #wumbo"/></li>
<li id="insta"><img src="/wp-content/uploads/2016/11/Instagram-color.png" alt="Follow us on Instagram #wumbo"/></li>
<li id="facebook"><img src="/wp-content/uploads/2016/11/Facebook-color.png" alt="Follow us on Facebook #wumbo"/></li>
</ul>
</div>
<div class="sub-footer">
<div class="container">
<div class="row">
<div class="col-md-5-footer">
<div class="footer-img">
<img src="https://www.wumbo.com/wp-content/uploads/2016/11/HullSpar_Slogan.png" alt="Made For The Modern Seafarer™"/>
<div/>
</div>
</div>

I'm re-positioned your div.snapcode footer and applied a css property to
#snapchat:hover ~ .snapcode-footer . hopes this will help you :)
.snapcode-footer {
position: absolute;
padding-top: 90px;
text-align: center;
left: 0;
right: 0;
}
.sub-sub-footer {
position: relative;
z-index: 1;
background-color: #F7F7F7;
padding-top: 35px;
padding-bottom: 20px;
}
.sub-footer {
position: relative;
z-index: 1;
background-color: #edeeef;
margin-top: 0px;
}
#snapchat:hover ~ .snapcode-footer{
z-index:999;
color:green;
position:relative;
margin-bottom:100px;
margin-left:50px;
}
<div class="sub-sub-footer">
<ul class="social-footer">
<li id="twitter"><img src="/wp-content/uploads/2016/11/Twitter-color.png" alt="Follow us on Twitter #hullandspar"/></li>
<li id="snapchat"><img src="/wp-content/uploads/2016/11/Snapchat-color.png" alt="Follow us on Snapchat #hullandspar"/></li>
<div class="snapcode-footer">
<img src="https://hullandspar.com/wp-content/uploads/2016/11/snapcode.png" width="250px" height="auto" alt="Scan to add us on Snapchat!">
</div>
<li id="insta"><img src="/wp-content/uploads/2016/11/Instagram-color.png" alt="Follow us on Instagram #hullandspar"/></li>
<li id="facebook"><img src="/wp-content/uploads/2016/11/Facebook-color.png" alt="Follow us on Facebook #hullandspar"/></li>
</ul>
</div>
<div class="sub-footer">
<div class="container">
<div class="row">
<div class="col-md-5-footer">
<div class="footer-img">
<img src="https://www.hullandspar.com/wp-content/uploads/2016/11/HullSpar_Slogan.png" alt="Made For The Modern Seafarer™"/>
</div>
</div>
</div>

I'd suggest giving snapcode-footer an id to make it easier to control.
<div class="snapcode-footer" id="snapcode">
<script>
var hover = 0;
</script>
Then you make a script on #snapchat
<li id="snapchat"onmouseenter="hover = 1" onmouseout="hover = 0"><img src="/wp-content/uploads/2016/11/Snapchat-color.png" alt="Follow us on Snapchat #hullandspar"/></li>
Lastly, you make a script for if the mouse is hovering over the #snapchat element to increase height or to stay in one place
<script>
setInterval("if(hover == 1){snapcode.top--}");
setInterval("if(hover == 0){snapcode.top = 0}");
</script>
