Template Literal Function not working as expected

I have a function that turns an array into modal window links as a template literal.
The code that creates the links works fine outside of the function
But once it gets rendered in the function it no longer works. I can't find any errors, but it does NOT work.
However, if I copy the HTML that the function renders and save that as actual HTML, that works fine on its own.
A good chunk of the JavaScript portion of the code is posted below. A full version is on Codepen.
There are two sections in the example on Codepen:
The first section has the code as it's rendered by the function.
The second section is copied from the Elements tab in Developer Tools and saved as actual HTML.

My apologies in advance for it not being stripped down to just the bare minimum. But in order to replicate the problem, it required more code than it probably should have had. I've been reworking this for the better part of a day without any insight as to what the real problem is. I've been creating functions using template literals just like this for years now, usually with a high success rate. Whatever the problem is, I need to know so I can get past it. The only anomaly that I spotted is that–in the version on Codepen–the only thing that doesn't work in that version is once the modal is displayed clicking on the background does not dismiss the modal like it does elsewhere. If that's significant as to what the problem may be, I'm not sure what the connection is.
Usually when I take the time to painstakingly write everything out like this I typically either spot the problem or figure out an alternative solution so there's no need to actually post a question, but this does not appear to be one of those times. As always, your help is very much appreciated!

The issue appears to just be timing. Your code is executed in order, and the first part gets all of the modal buttons on the page and sets the appropriate event listeners. Then the second part of your code adds 2 modal buttons, which were not present earlier.
By simply wrapping the first part of your code in a function and calling it later (or swapping the order of those two parts of code), everything works as expected.

For this i used the method [http://www.xpertdeveloper.com/2012/10/webpage-screenshot-with-html5-js/] , here screenshot is generated but without style also it is not downloading . Please help , is there any jQuery library available for this?

You can achieve this using the following JavaScript libraries ...
html2canvas ( for taking screenshot of webpage )
FileSave.js ( for downloading the screenshot as an image )

I found that dom-to-image did a much better job than html2canvas. See the following question & answer: https://stackoverflow.com/a/32776834/207981
If you're looking to download the image(s) you'll want to combine it with FileSaver.js (already mentioned here), and if you want to download a zip with multiple image files all generated client-side take a look at jszip.

Few options for this
either use this
<html>
<head>
<title> Download-Button </title>
</head>
<body>
<p> Click the image ! You can download! </p>
<a download="logo.png" href="http://localhost/folder/img/logo.png" title="Logo title">
<img alt="logo" src="http://localhost/folder/img/logo.png">
</a>
</body>
</html>
or You can use Mordernizr
or maybe this works
<a href="/path/to/image" download>
<img src="/path/to/image" />
</a>
refer to this link aswell

Unable to reset JavaScript bar graph

I have a bar graph created in JavaScript to display values using colors. I am having trouble resetting the bar graph. Basically what needs to happen is when the "reset" button is clicked, all bars clear values and reset to "0". Then the button needs to give the option to "Generate" and the previous values are shown again. Also, this is my first time using constant velocity to ease the bars up and down as the button is clicked to give it a little flair. Not sure what I am missing to have the data clear and be set to zero on the bottom line of the graph while using constant velocity to make it ease down and when button is clicked to restore the values to previous state. Any help is appreciated. Here is the code so far:
HTML
/*
* Some base values.
*/
var millisecondsPerFrame = 30;
/*
* Helper function for managing button event handlers.
*/
var setupButton = function(button, label, onclickHandler) {
button.value = label;
button.onclick = onclickHandler;
button.disabled = false;
};
var startConstantVelocityAnimation = function() {

Underline slide transition in buttons

I tried to search for tutorials on this effect. The effect that I wanted is an active underline (or border-bottom) under a link. When I click on a link, the underline will slide over to the next link and so on... One example is this question.
I know that what I have in html are buttons, not nav menu. So the coding would be different. I'm thinking that I might need to convert the buttons to nav menu if it doesn't work out.
Anyway, the problem is that I did try to use the example mentioned above to make the underline move to a clinked link. But it's not working...
Here's my code which is on codepen.
$(document).ready(function() {
$(".con-button").click(function(){
if(this.id == "c-all") {
$(".con-button").removeClass("active");
$("#c-all").addClass("active");
$('.offline').hide();
$('.offline').fadeIn("slow").show();
$('.online').hide();
$('.online').fadeIn("slow").show();
$('.none').fadeIn("slow").show();
} else if (this.id == "c-online") {
$(".con-button").removeClass("active");
$("#c-online").addClass("active");
$('.offline').hide();
$('.online').hide();
$('.online').fadeIn("slow").show();
$('.none').hide();
} else if (this.id == "c-offline") {
$(".con-button").removeClass("active");
$("#c-offline").addClass("active");
$('.offline').hide();
$('.offline').fadeIn("slow").show();
$('.online').hide();
$('.none').hide();
}
})
getSteams();
});

I made sure that .active is working in Javascript but I still need help making the underline moving from one link to another when clicked. All I know is that it has something to do with the CSS. Any help or tutorials are appreciated.

You can use this simple technique if you can use jQuery. It is quite generic and you can use any html elements whether nav, buttons or simple div's. You just need to have an outer element that contains all your links.
The idea is to find the position and width of the clicked anchor tag and then apply the same(or after adding some modification) to the underline element. To make its movement smooth you can add transition for left and width properties of this underline element.
$("#outer-container a").on("click", function(e){
e.preventDefault();
var cssObj = {};
cssObj.left = $(this).position().left;
cssObj.width = $(this).outerWidth();
$("#outer-container #underline").css( cssObj );
});//a click()
$("#outer-container a").eq(0).trigger("click");
#outer-container
{
text-align: center;
position: relative;
}
#outer-container a
{
color: #333;
display: inline-block;
padding: 0 10px;
text-decoration: none;
}
#outer-container #underline
{
content: "";
display: block;
position: absolute;
bottom: 0;
left: 0;
height: 2px;
width: 100px;
background-color: #333;
transition: left 0.3s ease, width 0.3s ease;
}

Javascript Slideshow Functions Not Working

I would please like an explanation to why the slideshow is not working. Below I have used an interval to perpetually change the slideshow, if userClick is false. The white and squared buttons (made of divs) are set to call upon two functions; slideRight() or slideLeft() and clicked(). When the buttons are clicked however, the clicked() function does not seem to change the variable, based on the data on top of the page.

Try changing the checking part to:
window.onload = function() {
setInterval(function () {
document.getElementById("uc").innerHTML = userClick;
}, 100);
}
The first argument of setInterval has to be a function (something that can be called), not a generic piece of code.
