Share 100vh between div and position:sticky navbar

I want to share the initial visible area of my page between a slideshow and my navbar like the below diagram which will then stick at the top when you scroll down the document. This is where I've run into issues.
I've tried doing something like height: 90vh for my slideshow and height: 10vh for my navbar but I want the website to be dynamic and able to fit to most resolutions until you hit cellphone level or at least like 200% zoom on Microsoft edge wherein another stylesheet will be used.
I've also tried placing them within the same div, setting height: 90% for the slideshow and height: auto for the navbar. This worked best in terms of how dynamic it is but the position: sticky obviously didn't work because it only traverses the height of the parent div.
The one that works best is setting the slideshow height to height: 90vh and allowing the navbar to go accordingly. It kinda sorta works but not nearly good enough for me.
The navbar has to initially be at the bottom then stick to the top. If possible I'd rather have a purely CSS solution, but I am open to javascript. Though I'd rather have pure javascript as opposed to jQuery but if it's well explained I'm okay with it.
The actual question is: How do I make my navbar and my slideshow share the initial visible height dynamically?
Here is all the relevant code:
#container {
display: flex;
flex-direction: column;
height: 100vh;
}
.slideshow-base {
flex-grow: 1;
width: 100%;
margin: 0px;
}
.slideshow-container {
height: 100%;
width: 100%;
position: relative;
overflow: hidden;
}
.Slides {
position: absolute;
transform: translateX(-100%);
transition: transform 2s;
display: inline-block;
width: 100%;
height: 100%;
margin: 0;
}
.Slides-Images {
width: 100%;
height: 100%;
object-fit: cover;
}
.navbar-base {
font-weight: bold;
z-index: 2;
font-variant: small-caps;
height: 100%;
width: auto;
top: 0px;
background-color: rgba(50, 64, 147, 0.9);
display: block;
border-bottom: 1px solid rgb(226, 208, 0);
}
<div id="container">

Use CSS Grids
body {
margin: 0;
}
#container {
width: 100vw;
background: #ccc;
padding: 10px;
height: 100vh;
display: grid;
grid-template-rows: 90vh 10vh;
grid-gap: 10px;
}
#container>div {
background: #999;
}
<section id="container">
<div>Sticky</div>
<div>NavBar</div>
</section>

Ok, I would use a flexbox approach for your initial view, then a bit of js to add a class on scroll:
window.onscroll = function() {
var nav = document.getElementById('nav');
var scrollTop = window.pageYOffset || document.body.scrollTop || document.documentElement.scrollTop;
if (scrollTop > 100) { // not sure how much you want it to scroll before it is made sticky
nav.classList.add("fixed");
} else {
nav.classList.remove("fixed");
}
}
body {
margin:0;
height:200vh; /* just so there is some scrolling */
}
.container {
height:100vh;
display:flex;
flex-direction:column;
}
.slideshow-base {
flex-grow:1; /* this will make shadow base take the rest of the available height to start with */
}
.fixed {
position:fixed;
top:0;
left:0;
right:0;
}
<div class="container">
<div class="slideshow-base" style="background-color: rgb(50, 64, 147); height: 90vh">
<div class="slideshow-container">
<div class="Slides">
<img src="~/Images/Slideshow/Gallery-1.jpg" class="Slides-Images">

<span class="dot" onclick="currentSlide(2)">᛫</span>
<span class="dot" onclick="currentSlide(3)">᛫</span>
</div>
</div>
</div>
<hr />
<!--Sticky Navbar-->
<div id="nav" class="navbar-base">
<ul>
<li class="navbar-button" style="display: inline-block;"> #Html.ActionLink("main page", "MainPage", "Home") </li>

You can probably wrap those 2 elements in a wrapper (and optionally give it a height) and use flexbox to make them share space.
In the example below, the slideshow will always cover 90% of the wrapper's height and nav will cover 10% of it.
.slideshow,
.nav {
border: 2px solid #000
}
.wrapper {
display: flex;
flex-direction: column;
height: 90vh
}
.nav {
/* An arbitrary value to start with */
flex-grow: 1;
}
.slideshow {
/* Grow this element 9 times more than the other element. */
flex-grow: 9;
}
<div class="wrapper">
<div class="slideshow">
Slideshow content
</div>
<nav class="nav">
Navigation content
</nav>
</div>

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>

How to make an image in a separate div change on hover of nav?

I have a site I'm working on where I have a nav bar in a div at the top of the page followed by a separate div which contains an image directly below it.
I'm trying to figure out the best way to change the image by hovering over each part of the nav bar.
Basically I want an image for home to show up when the home nav feature is hovered and so on with the rest of the menu.
UPDATE:
As I tried to explain before (not as clear as I could have) I want to make each nav bar element (Home, Downloads, etc.) show a different image in the div below it. Here is the section of code for the two elements.
<li class="active">Home</li>
<li >About</li>
<li >Mods</li>
<li>Forums</li>
<li >Downloads</li>
<li>Blog</li>
</ul>
</div>
</nav>
<div class="parallax-container">
<div class="container" style="background: rgb(55,71,79); width:960px; padding-top: 10px; padding-left: 50px; border: 2px; border-radius: 50px;">
<div class="row">
<div class="hover-image white-text col s12 l6">
<img src="homeimage.png" class="hover image" style="height:auto; width:auto; max-width: 860px; max-height: 860px;"/>
<h5 class="hover-header" style="padding-left: 20px;">Home</h2>
<p class="hover-paragraph" style="padding-left: 25px;">Welcome to the page!</p>
</div>
</div>
</div>
<div class="parallax"><img src="/img/image.png"></div>
</div>
<style>
.hover-image {
position: relative;
width: 100%;
margin: auto;
}
.hover-header {
position: absolute;
top: 350px;
left: 10;
width: 100%;
}
.hover-paragraph {
position: absolute;
top: 380px;
width: 100%;
}
</style>
Page Layout

Try CSS something like this;
.nav:hover .image{
background-image: url('path/to/image.ext');
}
If you can share your code, I can be more specific.

try this code -
CSS -
#navImage img{
display:block;
width:500px;
height:auto;
}
#myNav{
list-style-type: none;
}
#myNav li {
display: inline;
padding: 10px;
}
#myNav li a:hover {
color:#00ffff;
}
#navImage img{
display:none;
}
HTML
<ul id="myNav">
<li>Home</li>
<li>Page 1</li>
<li>Page 2</li>
<li>Page 3</li>
</ul>
<div id="navImage">
<img src="img_chania.jpg" alt="Chania">
<img src="img_chania2.jpg" alt="Chania">
<img src="img_flower.jpg" alt="Flower">
<img src="img_flower2.jpg" alt="Flower">
</div>
JS to initialize (with jQuery) -
$("#myNav li a").on('mouseover', function(){
$("#navImage img").hide().eq($(this).closest('li').index()).show();
});
Please note, if you are working on responsive design(using bootstrap navigation), you need to do changes accordingly.
jsfiddle - https://jsfiddle.net/guruling/k2zgot5r/

.myButtonLink {
display: block;
width: 100px;
height: 100px;
background: url('/path/to/myImage.png') bottom;
text-indent: -99999px;
}
.myButtonLink:hover {
background-position: 0 0;
}
<a class="myButtonLink" href="#LinkURL">Leaf</a>

Show Link on image at hovering in jquery

I'm using Bootstrap 3 and jQuery 1.9.1 to make a website where profile picture is shown in a <li> tag. I want to show the link of "Update Image" when I'm hovering over the image. So far I've managed to fade the image on hovering but I'm unable to show a link or text on hovering over image. Here are my codes,
JQUERY
$(function () {
$(".img-profile").hover(
function () {
$(this).fadeTo(200, 0.45);
},
function () {
$(this).fadeTo(200, 1);
});
});
CSS
.img-profile {
margin-top: 10px;
width: 200px;
height: 250px;
}
HTML
<div class="navbar-default sidebar" role="navigation">
<div class="sidebar-nav navbar-collapse">
<ul class="nav" id="side-menu">
<li>
<img class="img-responsive img-rounded img-profile" src="myimage.png" alt="profile_pic" />
</li>
</ul>
</div>
</div>
I've searched other sources but none of them works since it'll bug my own css styles. How can I show a link at the middle of the image on hovering? Need this help badly! Thanks.

Hope, if you want to do it without Jquery - even though if you want to manage it using jquery, it can also be done.. not a big issue
.img-profile {
margin-top: 10px;
width: 200px;
/* if image is bigger it will adjust according to parent width */
height: 250px;
display: inline-block;
}
.img-wrap {
display: inline-block;
position: relative;
}
.img-wrap:hover .img-profile {
opacity: 0.5;
}
.img-wrap .hover-div {
display: none;
position: absolute;
text-align: center;
top: 50%;
left: 0;
right: 0;
margin-top: -10px;
z-index: 10;
/* width of image container */
}
.img-wrap:hover .hover-div {
display: inline-block;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<div class="navbar-default sidebar" role="navigation">

<div class="hover-div">Update Image
</div>
</li>
</ul>
</div>
</div>

Yoy should try this. that is exactly you want.
$(function () {
$(".img-profile").hover(
function () {
$(this).fadeTo(200, 0.45);
$(this).closest("li").find("a").show();
},
function () {
$(this).fadeTo(200, 1);
$(this).closest("li").find("a").hide();
});
})
.img-profile {
margin-top: 10px;
width: 200px;
height: 250px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div class="navbar-default sidebar" role="navigation">
<div class="sidebar-nav navbar-collapse">
<ul class="nav" id="side-menu">
<li>
<img class="img-responsive img-rounded img-profile" src="https://i.stack.imgur.com/TwJmm.gif?s=328&g=1" alt="profile_pic" />Link that you want
</li>
</ul>
</div>
</div>

you can achieve all that using css alone.
html
<ul class="nav" id="side-menu">
<li>
<img class="img-responsive img-rounded img-profile" src="myimage.png" alt="profile_pic" />
<p class="text">change profile picture</p>
</li>
</ul>
css
.img-profile {
margin-top: 10px;
width: 200px;
height: 250px;
opacity: 1.0;
filter:alpha(opacity=100);
}
.text {
display: none;
}
img-profile:hover {
opacity: 0.45;
filter:alpha(opacity=45);
}
img-profile:hover + .text {
display: block;
}

Smooth Scrolling for absolute positioned contents

I am using this Page scroller.js to give smooth scroll effect to my page.
but it won't work.
Issue for this was that I was targeting the div which had position:absolute;. I still need this div to have position absolute and also have the smooth scroll work.
Here is my Html
<div id="wrapper">
<nav id="globalNav">
<h1><img src="img/logo.png" alt="SHISEIDO" /></h1>
<ul class="subMenu">
<li><img src="img/seperator.png" alt=""></li>
<li>TOP</li>
<li>CONCEPT</li>
<li>CONTACT</li>
<li><img src="img/seperator.png" alt=""></li>
<li><img src="img/seperator.png" alt=""></li>
<li><p class="copyright">Copyright © KOOGEN 2015<br>All rights reserved.</p></li>
</ul>
<div id="fbFeed">
<p></p>
</div>
</nav>
<div class="col-sm-8" id="left">
<div class="set">
</div><!-- set -->
</div>
<div class="col-sm-4" id="right">
<div id="inner1">
<div id="works"></div>
<div id="concept"></div>
<div id="contact"></div>
</div><!-- inner -->
</div>
</div><!-- #wrapper -->
So, #left #right divs have position absolute to create 3 column layout.
I added anchor link to my globalNav so that when I click, contents inside #right div will scroll smoothly.
heres my css added to #left and #right divs.
#left {
position: absolute;
top: 0px;
bottom: 0;
left: 218px;
width: 186px;
overflow-y: scroll;
background-color: rgba(255, 255, 255, 0.45);
padding-left: 6px;
}
#left .set{
padding-top: 230px;
}
#right {
position: absolute;
top: 0;
bottom: 0;
right: 0;
overflow-y: scroll;
width: 67.5%;
}
#right #works{
padding-top: 230px;
}
#right .inner{
position: relative;
}
Any help would be much appreciated!
Thank you for your time!
UPDATE:
This is the fiddle.

It works when the window's width is very narrow, but when I stretch it out to the ideal window size, smooth scroll stop working.

you can use for smooth scroll
$(document).on('click', 'a[href^="#"]', function(e) {
var id = $(this).attr('href');
var $id = $(id);
if ($id.size() === 0) {
return;
}
e.preventDefault();
var pos = $(id).offset().top;
pos = pos-95;
$('body, html').animate({scrollTop: pos});
});
