Search Bar showing footer when any word is typed in thats not on the product cards

I have implemented a search bar on my website and when a name of a product card is typed in it works. However, if you was to type in a word such as "lol' or any other word that is not included on the product cards the footer begins to show. I'm wanting the footer to stay in its current place which is at the bottom of the page.
I will be uploading code snippets and the files to my server so you can view the entire website and the problems I am experiencing.
I hope all of the information provided shows the problem I am experiencing.
[Click the product page to see the problem I am experiencing or click run snippet below][1]

function search_products() {

let x = document.getElementsByClassName('products');
for (i = 0; i < x.length; i++) {
if (!x[i].innerHTML.toLowerCase().includes(input)) {
x[i].style.display="none";
}
else {
x[i].style.display="list-item";
}

I would just wrap it with id or class and set it min-height:100vh;. Its the easiest way, not the cleanest code. Hope it helped!

Spacing problem between Header and Sidebar

I'm programming a page and I have a Header and a Sidebar but I'm in trouble with the top property overlapping my header, the sidebar would have to have the top value zeroed but in this scenario it overlaps my header by changing the value to 10 for example I solve this problem of overlapping but create an unwanted spacing when Scrolling. I am new to the world of web design but I have tried several solutions for such an event but none solves such a occurred.

As told there can be 2 solutions to your problem :
You can use z-index on header and put it above sidebar
For that have use z-index value of sidebar to be -1 . As using this you must be careful as some content may overlap(overlay) your sidebar so it is better to leave a margin on the left
Use sticky property to have it stick to top when scrolling
You have to make a lot of changes in your CSS to make a look right now , but for a start you can use display: block along position: sticky to have a start and improve on the go

With 1st solution there also comes some problem like your content will be hidden under header until you scroll . Here you can use margin and sticky for inside content of sidebar or it is better to improve CSS and go 2nd option

You can give dashboard overflow-Y: scroll and reduce its width to 100%-open sidebar width(flexbox will adjust dashboard´s width automatically if you give sidebar element min-width: max-content;). This is how you stick your sidebar in place without using position or z-index. I will give you a little example
const button = document.querySelector('button');
const sidebar = document.querySelector(".sidebar");
button.onclick = () => {
sidebar.classList.toggle('active');
}
body {
margin: 0;
padding: 0;
height: 100vh;
}
.header {
height: 10vh;
background: red;
}
.content {
display: flex;
flex-flow: row nowrap;
}
.content .sidebar {
width: 5%;
background: black;
height: 90vh;
}
.content .sidebar.active {
width: 20%;
}
.content .dashboard {
height: 90vh;
width: 100%;
background: green;
overflow-y: scroll;
scroll-behavior: smooth;
}
.content .dashboard .hard-coded-overflow {
height: 1000px;
}
<body>
<div class="header"></div>
<div class="content">
<div class="sidebar active">
<button class="close">close</button>
</div>
<div class="dashboard">
<div class="hard-coded-overflow">
</div>
</div>
</div>
</body>
You can add transition to make it seem like a proper animation and it is way better user experience than overlaping sidebar on top of main content( that should happen when media width is adequate for mobile devices).

How do I get my site to scroll properly on mobile

I am building a site with a js menu that loads content into a container div. The site works fine on desktop, and on the respsonsive mobile emulator on my desktop browser, but on my phone it doesn't scroll.

I think it has something to do with the height of the #page-content div that I have set to min-height: calc(100vh - 138px) to compensate for the navbar at the top and the footer at the bottom.
Alternatively it may have something to do with visibility or positioning on the other elements. The layout of the site changes completely on smaller devices...
I've tried adding -webkit-overflow-scrolling: touch; to various elements, but even when I set it to all elements using * {} it still doesn't scroll.
I've read a dozen posts some of which point to position: fixed so i've tried switching to absolute positioning...
It seems like the whole page tries to scroll instead of the #content or #page-content div... i'm just at a loss! PLEASE HELP!!!

Add below CSS inside #media only screen and (max-width: 800px) in your style.css at line no 4030. It'll unable your parent scroll and disable your individual container scroll and also you add an individual footer in each container. So I also hide all container's footer and visible only last container footer. Try this I hope it'll help you out. Thanks

Fluid responsive navigation with dropdown

I am trying to code a modal image gallery. I found an html code for one, that includes a little JS, but it doesn't come with any CSS. So when I click on the image, (currently only the top left one is linked up) the modal shows up at the bottom. I know nothing about JS or modals, could someone help me with what sort of code I would need to make the modal pop up over top of everything? Thanks in advance!

You can just add a bit of CSS:
#modal01 {
position: absolute;
top: 0;
width: 100%;
z-index: 999;
}
See the example on codepen: http://codepen.io/anon/pen/XjJAdw

Let's focus in on what modals exactly are. Take a look at this.
Basically, inside your head tag, add this code.
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
On your img tags, add this code.
<img data-toggle="modal" data-target="#myModal" src="http://static1.squarespace.com/static/5461836ee4b073a05b541f40/t/548df630e4b023e5238f8546/1418589745114/0image.jpg">
This is how to make your modal.
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
