Fixed Sidebar with Fixed Header and Scrollable Content

I'm looking to have a fixed sidebar that works on mobile with a fixed header and a scrollable content section. I'd like to have the sidebar itself fill 100% of the view height, but be a certain % of the overall screen width.
I have a solution with 100vh that works on desktop, but on mobile the bottom 'navigation' links of the browser overlap the content.
Is there a known solution to make this work? At this point, I don't care if I have to use JavaScript to make it work right.

If the only problem with your current sidebar styling is that it overlaps bottom nav links on mobile devices, you can address that with a media query:
#media screen and (max-height: 450px) {
.sidebar
height: calc(100% - 50px);
}
}

// When the user scrolls the page, execute myFunction
window.onscroll = function() {myFunction()};
// Get the header
var header = document.getElementById("myHeader");
// Get the offset position of the navbar
var sticky = header.offsetTop;
// Add the sticky class to the header when you reach its scroll position. Remove "sticky" when you leave the scroll position
function myFunction() {
if (window.pageYOffset > sticky) {
header.classList.add("sticky");
} else {
header.classList.remove("sticky");
}
}
.sidenav {
margin-top: 100px;
height: 100%; /* Full-height: remove this if you want "auto" height */
width: 160px; /* Set the width of the sidebar */
position: fixed; /* Fixed Sidebar (stay in place on scroll) */
z-index: 1; /* Stay on top */
top: 0; /* Stay at the top */
left: 0;
background-color: #111; /* Black */
overflow-x: hidden; /* Disable horizontal scroll */
padding-top: 20px;
}
/* The navigation menu links */
.sidenav a {
padding: 6px 8px 6px 16px;
text-decoration: none;
font-size: 25px;
color: #818181;
display: block;
}
/* When you mouse over the navigation links, change their color */
.sidenav a:hover {
color: #f1f1f1;
}
/* Style page content */
.main {
margin-left: 160px; /* Same as the width of the sidebar */
padding: 0px 10px;
}
/* On smaller screens, where height is less than 450px, change the style of the sidebar (less padding and a smaller font size) */
#media screen and (max-height: 450px) {
.sidenav {padding-top: 15px;}
.sidenav a {font-size: 18px;}
}
/* Style the header */
.header {
padding: 10px 16px;
background: #555;
color: #f1f1f1;
margin: 0px;
}
/* Page content */
.content {
padding: 16px;
}
/* The sticky class is added to the header with JS when it reaches its scroll position */
.sticky {
position: fixed;
top: 0;
width: 100%
}
/* Add some top padding to the page content to prevent sudden quick movement (as the header gets a new position at the top of the page (position:fixed and top:0) */
.sticky + .content {
padding-top: 100px;
}

Make the CTA button stick to the bottom of the page when scrolling

I want to make a CTA button that sticks to the bottom of the page after page scroll reaches to some extent. Kindly look at the image below:
The rules follow:
On load, it should be on the original position of the CTA button.
When the page is getting scrolled, the CTA button will follow.
When the CTA button reaches to the top of the window, the button will move to the bottom-right corner and remains sticky over there.
Any codepen, jsfiddle or website references about this kind of interaction will be appreciated.

There are multiple ways to do this like using plugins or using simple CSS and JavaScript(below example). If you are looking for animation to button on the scroll you can make some adjustments in CSS with animation code or I guess some of the plugins are already doing this.
window.onscroll = function() {myFunction()};
var btn = document.getElementById("floatBtn");
var sticky = btn.offsetTop;
function myFunction() {
if (window.pageYOffset >= sticky) {
btn.classList.add("sticky")
} else {
btn.classList.remove("sticky");
}

Hide the content under transparent fixed navbar while scrolling down

the problem:
I have transparent fixed navbar with some gap (margin-top) and below content, which is located under the navbar while scrolling down globally. The problem is that navbar is transparent and the background of the page is a dynamic slideshow of different images so I can't use z-index and hide it by changing background color or put image same as background..
In conclusion:
Transparent fixed navbar with gap
Dynamic images background
It has to be global scrolling (can't use scrolling for div content)
I'am using bootstrap 3

Sorry for problems with understanding me, here is code:
http://jsfiddle.net/5myw4e26/

if you're using a position fixed at your navbar you can do a top div empty with float left and a height with the size of your navbar.

I managed to accomplish what you we're trying to do. It's probably not the best solution, but it works.
Using JQuery I calculated when a paragraph (p.content) and the navigation-bar collided.
There's more than enough to finetune, so you can adjust it to your needs.
JQuery
$(document).ready(function() {
$(document).scroll(function() {
$("p").each(function() {
if ($(this).offset().top <= $(document).scrollTop() + 32) {
$(this).css("opacity", "0");
} else {
$(this).css("opacity", "1");
}
});
});
});
Note that the 32 in $(this).offset().top <= $(document).scrollTop() + 32 is the height of the navigation bar.
Example:
$(document).ready(function() {
$(document).scroll(function() {
$("p").each(function() {
if ($(this).offset().top <= $(document).scrollTop() + 32) {
$(this).css("opacity", "0");
} else {
$(this).css("opacity", "1");
}
});
});
});

Fading effect between switching divs

I'm using http://tympanus.net/Development/PageTransitions/ for my main pages, the code below is used within a single page to showcase other different content info. All pages coded are in one index file.
The code below is used to switch between divs.
I tried using simple javascript onclick to make the pages fadeIn/fadeOut but it couldn't work.
jQuery:
<script type="text/javascript">
function showDiv(idInfo) {
var sel = document.getElementById('divLinks').getElementsByTagName('div');
for (var i = 0; i < sel.length; i++) {
sel[i].style.display = 'none';
}
document.getElementById('container' + idInfo).style.display = 'block';
}
$("#fade").click(function () {
$('#container1').fadeOut('slow');
$('#container2').fadeIn('slow');
});
</script>
CSS:
<style type="text/css">
#container1, #container2, #container3 {
display:none;
width:100%;
height:auto;
}
</style>
HTML:
<img src="img/thumbnail1.png" /><br>click to see content 1
<img src="img/thumbnail2.png" /><br>click to see content 2
<img src="img/thumbnail3.png" /><br>click to see content 3
<div id="container1">content1</div>
<div id="container2">content2</div>
<div id="container3">content3</div>
Just need the .onclick fade effect to work after clicking on the link.
Many thanks in advance!

I think that this is what you are aiming for:
Online Demo
HTML:
<div class="links">
click to see content 1
click to see content 2
click to see content 3
</div>
<div class="content-divs">
<div>content0</div>
<div>content1</div>
<div>content2</div>
</div>
JavaScript:
$(".links a").click(function () {
var id = $(this).data('toggle');
showDiv(id);
});
function showDiv(id) {
// hide all other
var divs = $('.content-divs');
divs.children().each(function(index) {
$(this).hide();
});
// fade the correct one in.
divs.children('div:nth-child('+id+')').fadeIn();
}
Same css.
Since you are already using jQuery, why not use all it's functions?
You could do that with onclick="showDiv(id)", but jsfiddle does not work with that, so .data('toggle') is a nice workaround.

It seems you may be making this a little bit more complicated then it needs to be, try this out:
<script type="text/javascript">
$(document).ready(function(){
var curr = 1
$('.fader').click(function(){
var next_attr = $(this).data('num');
if(curr != next_attr){
$('div[data-num="'+curr+'"]').hide(1000, function(){
$('div[data-num="'+next_attr+'"]').show(1000);
});
curr = next_attr
}
});
});
</script>
Here is the html
<div class="links">
<a class=".fader" data-num="1">Show Container 1</a>
<a class=".fader" data-num="2">Show Container 2</a>
<a class=".fader" data-num="3">Show Container 3</a>
</div>
<div class="containers">
<div id="container1" data-num="1">Container 1</div>
<div id="container2" data-num="2">Container 2</div>
<div id="container3" data-num="3">Container 3</div>
</div>
and here is the css
#container2, #container3{
display:none;
width:100%;
height:auto;
}
that should give you the ability to switch between the 3 containers by clicking the links corresponding to them. I used a data attribute to link the containers to there links. When a link is clicked it looks for div with the same data-num and fades out the current one once its faded out it fades in the new one and sets the curr variable.

You can actually do this in pure CSS. (Not supported for IE 8-)

How to set the height of a floated div to the same height of its neighbour

I am trying to create a simple 2 column layout with a header and a footer.
I have the following HTML
<body>
<div id="header">
<h1>Title Bar</h1>
</div>
<div id="content">
<div id="left">
left
</div>
<div id="right">
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc elementum neque id eros auctor tristique. Fusce quam lorem, vestibulum ut magna et, cursus molestie libero. Suspendisse sed mauris vitae diam mattis pellentesque. Nulla neque tortor, varius quis augue vel, commodo tincidunt elit. Maecenas vel odio nec velit faucibus fringilla. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. Vestibulum arcu libero, auctor vitae urna eget, blandit fringilla justo. Fusce eu enim id nisi condimentum dictum sit amet non lectus.
Aenean at nulla odio. Vestibulum eleifend massa vitae velit tempor, non auctor velit imperdiet. Nunc ac odio eu justo pretium luctus. Nulla vestibulum urna sed est fermentum aliquam. Etiam eget erat eu tortor dictum rhoncus a nec justo. Sed eu dui ut leo lobortis laoreet quis sed sem. Nulla consectetur augue tristique dignissim viverra. Proin tincidunt tincidunt libero a iaculis. Etiam leo elit, cursus at velit sed, faucibus pretium leo. Ut viverra mattis sodales. Morbi hendrerit quam eu est dignissim congue. Pellentesque quis metus commodo sapien interdum rutrum pellentesque at risus. Sed tempor, orci nec tincidunt dictum, turpis purus mattis enim, ut sodales odio arcu quis sem. Praesent vitae justo lorem. Nam ultrices enim at consectetur vehicula. Ut luctus interdum urna, rutrum luctus orci varius vel.
Integer pharetra nisi vitae massa condimentum, ac hendrerit magna commodo. Pellentesque sit amet neque ac mauris hendrerit scelerisque quis nec sapien. Nullam tempor odio sed tristique interdum. Donec non aliquet quam. Nunc ac adipiscing tortor. Mauris nec nisl accumsan, ullamcorper metus eu, dictum mi. Mauris id adipiscing lectus. Morbi dignissim scelerisque purus ut ullamcorper. Nu
nc placerat ipsum tortor, quis pretium est sagittis nec. In lacus eros, volutpat eu convallis a, ullamcorper vel leo. Quisque vel orci ultricies, molestie nisi non, congue leo. Nulla orci metus, vehicula at laoreet ut, congue nec sem. Proin tempor justo ut odio vestibulum suscipit in a eros. Sed fermentum et sapien id aliquam. Donec at erat bibendum, fringilla odio sit amet, sagittis nibh.
Morbi accumsan ullamcorper leo vel viverra. In ac imperdiet libero, id cursus eros. Morbi sed auctor quam, ac ullamcorper metus. Morbi et vestibulum justo, et volutpat libero. Duis pretium magna sapien, at porta justo sodales ve
l. Sed consequat magna odio, eu mattis risus malesuada vel. Aliquam tristique accumsan fermentum. Morbi interdum nunc vitae viverra pulvinar.
Donec neque magna, sodales dapibus imperdiet non, suscipit eget ipsum. Etiam nec dolor ut nisi pharetra dictum non eget augue. Etiam tincidunt mi id est euismod, ut venenatis neque tempus. Praesent lacinia risus metus, at condimentum diam vestibulum et. Integer ac mi nec enim facilisis pharetra. Nunc sed nibh libero. Duis imperdiet sapien id euismod viverra. Integer aliquam metus a nulla tincidunt eleifend. Donec a porttitor tortor. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Aliquam convallis aliquam dolor. Morbi eu velit quam. Nullam sed neque id risus aliquam lobortis. Sed vel pulvinar velit, id varius mauris. Sed justo nunc, laoreet eu velit et, pulvinar eleifend lacus. Phasellus tristique orci vitae dignissim imperdiet.
</div>
</div>
<div id="footer">
<h5>Footer </h5>
</div>
</body>
and the following css
body {
background-color: red;
margin: 0px;
}
body h1 {
margin: 0px;
}
#header {
background-color: blue;
color: white;
height: 80px;
}
#content {
width: 700px;
}
#left {
background-color: black;
color: pink;
float: left;
width: 100px;
height: 100%;
}
#right {
background-color: lightgreen;
color: brown;
}
#footer {
background-color: yellow;
color: blue;
clear: both;
height: 40px;
}
I want to make sure that the height of the left Div is the same as the height of the right div, regardless of what content is in the right div.
To do this I reverted to java script with this
$(document).ready(function () {
adjustLeftHeight();
});
$(window).resize(function () {
adjustLeftHeight();
});
function adjustLeftHeight() {
$("#left").height($("#content").height());
}
This doesn't quite work in that when the adjustLeftHeight is executed its sets the lefts height to the height of the content div, but because of the extra space taken up by the increase in the height of the left div the content in the right div gets pushed down increasing the height of the right div and leaving a gap between the heights of the 2 divs.
see this fiddle for a worked example http://jsfiddle.net/W3P4U/
Is there a way to achieve a 2 column layout where the height of both columns is the height of the tallest column.

See updated fiddle.
Changes:
1: add float: right to right div and width: 300px (being content's width - left's width), if you want them fixed as width;
2: change adjustLeftHeight function to this:
function adjustLeftHeight() {
var left = $("#left"),
right = $("#right");
if (left.height() > right.height())
right.height(left.height());
else
left.height(right.height());
}
