Stop fixed div from scroll in a certain point. What is missing in my code? Jquery

I have this div called "floating" and it has to start in the bottom of the screen, but as the user scrolls, it has to move (kindly) to the top and maintain fixed until reaches another div down below.
What I have so far is making the div stops correctly, but it's not moving to the top of the screen when the user start to scroll. What is missing here?
HTML
<div class="container">
<a id="floating" href="#stop"></a>
<div id="dummy">some content</div>
<div id="stop">other content near the footer</div>
<footer>footer</footer>
</div>
CSS
#floating{
display: block;
position: fixed;
bottom: 5%;
right: 5%;
width: 115px;
height: 115px;
color: #fff;
z-index: 1;
background-color: #0055db;
}
JQUERY
function checkOffset() {
var a=$(document).scrollTop()+window.innerHeight;
var b=$('#stop').offset().top;
if (a<b) {
$('#floating').css('bottom', '5%');
} else {
$('#floating').css('bottom', (20+(a-b))+'px');
}
}
$(document).ready(checkOffset);
$(document).scroll(checkOffset);
I appreciate all the help! Thank you!

Try using JQuery Animate
<script>
$(document).ready(function(){
$(document).scroll(function(){
$("#floating").animate({top: '10px'}, "slow");
});
});
</script>

How to scroll beyond fixed position elements on a page with TOC without using JS?

Any ideas how to fix this problem: On a page with TOC (table of contents) with links pointing to hashtags within the same page, when the browser scrolls down other fixed position elements hide it. The browser should scroll further down to avoid being hidden by the fixed elements.
Fiddle to demonstrate this problem: https://jsfiddle.net/fcro6mth/ Click Section One or Section Two - the browser scrolls down to it but its hidden by the fixed header
Solution with JS: https://jsfiddle.net/fcro6mth/1/
Can you think of any solution that doesn’t involve JS?
Code from JS fiddle:
HTML:
<header>
This is the fixed position header
<nav>
Section One
Section Two
Section Three
</nav>
</header>
<div class="body">
This is the body.
<section id="section1">This is section one</section>
<section id="section2">This is section two</section>
<section id="section3">This is section three</section>
</div>
CSS:
section {
background: lightgrey;
margin: 20px 0;
padding: 20px 10px;
height: 300px;
}
header {
background-color: grey;
position: fixed;
top: 0;
padding: 10px;
width: 100%;
box-sizing: border-box;
left: 0;
color: white;
}
.body {
margin: 70px 10px 0 10px;
}
JavaScript:
$("nav a").click(function (event) {
var $target = $(event.currentTarget),
$scrollToTarget = $($target.attr("href")),
$header = $("header"),
prop = {
scrollTop: $scrollToTarget.offset().top - $header.outerHeight(true)
},
speed = 1000;
$('html, body').animate(prop, speed);
});

Nice example to make hidden anchors for offsetting your sections.

Solution
I wrapped your sections in div-wrappers gave them the IDs, padded them down and pulled them back up with a negative margin.
This results in the exact same appearance, but the links do what you want them to do.
Example:
HTML:
<div id="section1" class="wrapper">
<section >This is section one</section>
</div>
CSS:
.wrapper {
padding-top: 50px;
margin-top: -50px;
}

I have struggled with this issue a lot in designing a webpage with a combined banner / navbar of about 300px fixed at the top of a page full of short items linked to by anchor links from the website's home page.
The problem I have found with the "margin-top: -XXpx; padding-top: XXpx" approach is that the invisible padding overlaid the preceding item, meaning that active content (ie. links) were blocked. I overcame this by applying positioning to the anchored elements and setting the z-index so that the first item was on top of the stack with each subsequent item lower in the stack - like this:
CSS
.anchored-element {
padding-top: 300px;
margin-top: -300px;
position: relative;
}
HTML
<div class="anchored-element" style="z-index: 99">FIRST ITEM</div>
<div class="anchored-element" style="z-index: 98">SECOND ITEM</div>
<div class="anchored-element" style="z-index: 97">THIRD ITEM</div>
... etc
This provided a fix that worked for me across Firefox, Safari and Chrome on my desktop, and on my iOS devices. I hope this helps others tackle this very frustrating issue in bootstrap!

bigvideo.js - stack DIVs over and under bigvideo container

So I've started playing around with bigvideo.js (which is built on top of video.js) and it works fine for the basic usage of having a fixed background video over the whole screen. I have also managed to show it inside of a div.
My problem though, is that I can't seem to stack other DIVs with other content over or under the bigvideo.js container div, and I can't seem to figure out how to solve this.
My HTML:
<div style="float: left; width: 100%; height: 300px;">
<h1>hi there</h1>
</div>
<div style="float: left; width: 100%; height: 500px;" id="intro-video-container">
</div>
JS firing up bigvideo:
$(function() {
var BV = new $.BigVideo({container: $('#intro-video-container'),useFlashForFirefox:false});
BV.init();
BV.show('intro.mp4',{ambient:true});
});
So the video container div ALWAYS gets stuck up to the left top of the body, no matter if I try to force it down with margin-top, or place divs before it, etc.
Any ideas?

Update, here is an illustration of what I kind of what to achieve:

Try to use container div (so called wrapping) in your page where you will place the desired content (as on the plugin's example page):
CSS
.box {
background:#444; background:rgba(0,0,0,.6);
padding:20px;
border-radius:5px;
margin-bottom:20px;
}
.main {
position:relative;
margin:50px 50px 440px 220px;
min-width:300px;
-webkit-transition-duration:0.6s;-moz-transition-duration:0.6s;-ms-transition-duration:0.6s;-o-transition-duration:0.6s;transition-duration:0.6s;
}
.dimmed {
color: #ccc;
}
#big-video-wrap {
height: 100%;
left: 0;
overflow: hidden;
position: fixed;
top: 0;
width: 100%;
}
HTML
<div id="big-video-wrap"></div>
<div class="main">
<div id="overview" class="box">
<h1>BigVideo<span class="dimmed"><small>.</small>js</span></h1>
<h2>Simple Ambient Video Example</h2>
</div>
</div>
JavaScript
$(function() {
var BV = new $.BigVideo({container: $('#big-video-wrap'),useFlashForFirefox:false});
BV.init();
BV.show('intro.mp4',{ambient:true});
});
EDIT:
Now, it is more clear what you are trying to achieve, the simplest solution is to include an iframe on place of the div, which points to your full-screen video page.
I.e. create page video.html with all initializations and plug-in includes, then use it as source of your iframe on main page. Your iframe can be styled to match the desired dimensions (for example 100% width and 300px height).

clicking one hyperlink to change the css styles of more than one different divs

I am having different div's on my website and I would like to do following
when I am clicking one link, that will trigger a change inside the css code of more than one div's. For example if I click on clients I would like to make the ul element with class="rslides" to get property of heigh="0px" and than another div layer to expand below this one.
But I have 2 problems:
first is that I am using a responsive slider for which i to make its height="0px" , I have to change the class property.
other issue is how to make one link trigger 2 actions for the second div. I tried with triggers but it is limited to one element per "id"
DOM Structure:
<div id="slider">
<div id="index_slider">
<ul class="rslides" >
<li><img src="img/index_design_02.jpg"></li>
<li><img src="img/index_design_03.jpg"></li>
</ul>
</div>
</div>
JS CODE:
<script src="js/responsiveslides.min.js"></script>
<script>
$(function() {
$(".rslides").responsiveSlides({
speed: 1000,
maxwidth: 1200
});
});
</script>
<div id="menu">clients</div>
<div id="second_slider"></div>
THE CSS CODE fot the both tirgers of the slider:
.rslides {
position: relative;
list-style: none;
overflow: hidden;
width: 100%;
padding: 0;
margin: 0;
-webkit-transition:all 1s ease-in-out;
}
.rslides:target {
position: relative;
list-style: none;
overflow: hidden;
width: 100%;
padding: 0;
margin: 0;
height:0px;
}
Here is link to JSfiddle
where my goal is once clicked on the link the div called "menu" to go on the top with sliding transition and the other div called "second_slider" to expand on the bottom, and the slider to disapear.

Depending on your markup, you should be able to target more than one div. The only limitation would be each target must a child of your link target.
<div class="rslides">
<div id="target-a">
<div class="sub-target-one"></div>
<div class="sub-target-two"></div>
</div>
</div>
The way you would go about it is like this:
.rslides:target > .sub-target-one,
.rsiides:target > .sub-target-two {
/* rules go here */
}

On touching uppermost div selects contents of div under it - z-index property

I have a strange problem though, when i click the content with z-index 20, the thing with z-index 1 gets selected in my phone.
The image has both the screen shot - the part on the right side of the image is only for illustrating my problem, as such the white gray div is behind my content div.
Can someone please rescue.

<h3>Questions</h3>
<div class="demo-social">
</div>
<h4>Java</h4>
<ul>
<li>What is Java?</li>
<li>Uses of Inheritence?</li>
...
</div>
</div>
<div id="content" class="snap-content">
my content goes here
</div>
</div>
</body>

Surely because "Uses of inheritance" is the only link element (other than "What is java"), it will be selected - there's nothing else to select!
Try setting the display of that element to "none" when it is hidden.

You could try to hook into the event when clicking / dragging on the content panel and do an event.stopPropagation(); or an event.preventDefault(); when the panel is closed.
As far as i know, you can see that coz Snap.js add's corresponding classes like (class="snapjs-right" or class="snapjs-left") to the body in order to indicate if a panel is open or not.
So first you've got to check that.
With jQuery it would look something like this:
$(document).ready(function() {
$("#UsesofInheritence_Anchor_ID").bind("click", function() {
if (!($('body').hasClass("snapjs-right"))){
event.stopPropagation();
event.preventDefault();
}
});
});
