JQuery Offset issue when div position is fixed

I have a website which has a page layout and style something like mentioned in this JsFiddle
Now Using JQuery when I click on the button, content is being displayed properly as shown below:
But when I first scroll the page and then click the button, content is not displaying properly as shown:
Can you please guide me to handle this situation ?
I have used below jQuery for this. But it seems offset or position is not working
$('#btn').click(function(){
var t = $(this).offset();
console.log(t);
$('.control-container').css('top', t.top + 20 + 'px');
$('.control-container').css('display', 'block');
});
$(document).on('scroll', function(){
$('.control-container').css('display', 'none');
});

You don't need to use offset to achieve that... And if you need to keep CSS with position:fixed, you need to switch it in javascript to static.
The thing you are looking for is simply display:table ...
$('#btn').click(function(){
$('.control-container').css({'display': 'table','position': 'static'});
});
$(document).on('scroll', function(){
$('.control-container').css({'display': 'none','position': 'fixed'});
});
Check out this JSFiddle
But if you really need a solution with position:fixed based on button position, you should try this way:
$('#btn').click(function(){
var button_fixed_position = $('#btn').get(0).getBoundingClientRect();
$('.control-container').css({'display': 'block','left' : button_fixed_position.left, 'top' : button_fixed_position.bottom});
});
$(document).on('scroll', function(){
$('.control-container').css({'display': 'none'});
});
Check out second JSFiddle

There is no need to specifically mention position property here.
Also remove the closing a tag and replace it with </button>
Currently container is occupying full width ,but that can also be set
$('#btn').click(function() {
var t = $(this).offset();
console.log(t);
$('.control-container').css('top', t.top + 30 + 'px');
$('.control-container').css('display', 'block');
});
$(document).on('scroll', function() {
$('.control-container').css('display', 'none');
});

Keep me exactly underneath 'Click Me' when Page is scrolled.

CSS position fixed property positions an element referencing view's/body's dimension.
If you have access of modifying CSS, then just remove the position: fixed; property from .control-container.
If you don't have access, then using script add position: static !important property to .control-container.
$('.control-container').css('cssText', 'position: static !important');

Fix navbar to top of page when scrolling

I'm trying to make a navbar similar to the one on Linus Tech tips (https://linustechtips.com/main/) for a school assignment. I'm at the real basic level of Javascript and I cooked up a pinnable navbar but when I made it there was no banner above it. Now there is a banner above it and I don't know how to make the navbar push to the top when I start scrolling.
Here is my HTML:
<div class="navContainer">
<div class="topBanner">
<img src="images/topbanner.png" id="topBannerimg"/>
</div>
<div id="navbar">
<button onclick="pinfunc()"><i id="pin" class="fa fa-thumb-tack fa-2x navButton" id="pinbtn" aria-hidden="true"></i></button>
</div>
</div>
Here is my Javascript:
var pinned = 1;
console.log(pinned);
function pinfunc() {
if (pinned == 1) {
document.getElementById("navbar").style.position= "relative";
document.getElementById("pin").style.color = "black";
document.getElementById("pin").style.transform = "rotate(0deg)";
pinned=0;
}
else if (pinned == 0) {
document.getElementById("navbar").style.position="fixed";
document.getElementById("pin").style.color = "red";
document.getElementById("pin").style.transform = "rotate(270deg)";
pinned=1;
}
}
And here is my CSS:
body{
margin: 0 auto;
}
.navContainer{
width: 100%;
margin: 0 auto;
}
#topBannerimg{
width: 100%;
margin: 0;
display:block
}
.navButton{
height: 25px;
width: 25px;
}
.fa-thumb-tack{
font-size: 50px;
color: red;
transform: rotate(270deg);
}
.container{
height: 1000px;
width: 90%;
margin: 0 auto;
}
#navbar{
height: 50px;
width: 100%;
position: fixed;
margin: 0 auto;
background-color: #D35300;
}
#nav{
background-color: #D35300;
height: 50px;
}
I'm just looking to create a basic one of the LTT forum - no need for the toggle button to fade out or anything.
This is my first post so I'm not 100% sure how to do stuff.
Thanks in advance.

If you are allowed to use external JS or CSS libraries, then try the Affix plugin for bootstrap. (link: http://www.w3schools.com/bootstrap/bootstrap_affix.asp). It makes what you are trying to accomplish simple.
If you are not allowed to use any external libraries then, I suggest you read this: http://getbootstrap.com/javascript/#affix-examples and try to implement it yourself.
Good Luck!
So I got it working with the following HTML, JS, and CSS files:
HTML
<html>
<head>
<link rel="stylesheet" href="path/to/font-awesome.css/file" type="text/css">
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<!-- Custom CSS File Below -->
<link href="/path/to/custom/css" rel="stylesheet" type="text/css">
</head>
<body>
<div class="topBanner">
<img src="images/topbanner.png" id="topBannerimg"/>
</div>
<div id="navbar" data-spy="affix" data-offset-top="100">
<button onclick="pinfunc()"><i id="pin" class="fa fa-thumb-tack fa-2x navButton" aria-hidden="true"></i></button>
</div>
<div id="SpaceFiller"></div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.2/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<script src="path/to/custom/js/file"></script>
</body>
</html>
The key things to learn from this HTML are the loading the JS files at the bottom of the body tag so the page can load first, and the order in which the CSS and JS files are loaded. The SpacFiller div is just there to enable scrolling. Also, note that I removed your navbar-container as it didn't seem necessary.
Javascript
var pinned = true;
function pinfunc() {
var $pin = $("#pin");
var $navbar = $("#navbar");
if (pinned) {
$pin.css({
'color': 'black',
'transform': 'rotate(0deg)'
});
console.log("not pinned")
$(window).off('.affix');
$navbar.removeClass('affix affix-top affix-bottom');
$navbar.removeData("bs.affix");
pinned = false;
} else {
$pin.css({
'color': 'red',
'transform': 'rotate(270deg)'
});
$(window).on('.affix');
$navbar.addClass('affix');
$navbar.affix({
offset: 100
});
pinned= true;
}
}
This JS uses jQuery Selectors (which actually uses sizzle.js I believe) to get access to HTML elements via their IDs. Using the returned jQuery object, the function sets the appropriate CSS and then toggles affix using functions you can read about here: http://getbootstrap.com/javascript/#affix, https://api.jquery.com/removeclass/, https://api.jquery.com/jQuery.removeData/, http://api.jquery.com/off/. Also, you were using 0 and 1 for the pinned values but it is good practice to use boolean values (true and false) as shown.
CSS
body{
margin: 0 auto;
}
.affix {
top: 0;
width: 100%;
}
.affix + .container-fluid {
padding-top: 70px;
}
#topBannerimg{
width: 100%;
margin: 0;
display:block;
height: 100px;
top: 0px;
}
.navButton{
height: 25px;
width: 25px;
}
.fa-thumb-tack{
font-size: 50px;
color: red;
transform: rotate(270deg);
}
#navbar{
height: 50px;
width: 100%;
margin: 0 auto;
background-color: #D35300;
}
#SpaceFiller {
height: 10000px;
background-color: darkgreen;
}
I think the CSS is self-explanatory, but if it is unclear go ahead and ask for clarification. Hope this helps! :D
Edit: You can also put the onclick attribute on the i tag itself and get rid of the button wrapper if you want to get rid of the white button background.

Cannot get div element by id to display gif in internet explorer

I am trying to make a .gif image display in a loading window to alert my user that loading is underway, quite simple. I was doing it using only css and background property like this:
/background: url(ajax-loader.gif) no-repeat center #fff;/
but my .gif was not loading in internet explorer. So I've made a research and found this and, based on J.Davies's solution, I have implemented this instead in my js file:
function ShowProgress() {
if (!spinnerVisible) {
$('div#layer').fadeIn("fast");
$('div#spinner').fadeIn("fast");
spinnerVisible = true;
var pb = $('#spinner');
pb.innerHTML = '<img src="./ajax-loader.gif" width=200 height=40/>';
pb.style.display = "";
}
}
My problem is that it works still in chrome, but I get a crash in internet explorer saying that it pb is undefined. Is there a specificity on how to work with jquery and internet explorer? For information, here's my display:
<div id="body">
#RenderSection("featured", false)
<section class="content-wrapper main-content clear-fix">
<section>
#Html.Partial("MessageDisplay")
</section>
<div id="layer"></div>
<div id="spinner">
Loading, please wait...
</div>
#RenderBody()
</section>
</div>
And the css saying that spinner and layer div are hidden:
div#spinner {
display: none;
width: 300px;
height: 300px;
position: fixed;
top: 40%;
left: 45%;
/*background: url(ajax-loader.gif) no-repeat center #fff;*/
text-align: center;
padding: 10px;
font: normal 16px Tahoma, Geneva, sans-serif;
border: 1px solid #666;
margin-left: -50px;
margin-top: -50px;
z-index: 2;
overflow: auto;
}
div#layer {
display: none;
width: 100%;
height: 100%;
position: fixed;
top: 0;
left: 0;
background-color: #a4a3a3;
background-color: rgba(164, 163, 163, 0.5);
z-index: 1;
overflow: auto;
-moz-opacity: 0.5
}

pb is a jQuery object. not a dom reference so there is no innerHTML or style properties in it. You need to use the utility methods provided by jQuery to set those
var pb = $('#spinner');
pb.html('<img src="./ajax-loader.gif" width=200 height=40/>').show();
In your case you can use .html() to set the innerHTML and .show() to make it visible

Change this :
var pb = $('#spinner');
pb.innerHTML = '<img src="./ajax-loader.gif" width=200 height=40/>';
pb.style.display = "";
with this :
var pb = $('#spinner');
pb.html('<img src="./ajax-loader.gif" width=200 height=40/>');
pb.css({'display':''});
Plus I must add that something IE8 have issue with fadeIn / fadeOut so I would recommande if you still have a problem to try .show() / hide() instead.

I have accepted Arun's answer because it has helped me get to the solution. Based on his answer and my css, I have finally managed to make this jquery call:
function ShowProgress() {
if (!spinnerVisible) {
$('div#layer').fadeIn("fast");
$('div#spinner').fadeIn("fast");
spinnerVisible = true;
var spinner = $('#spinner');
spinner.append('<img src="../../Content/ajax-loader.gif" width="250" height="250"/>').css('background', '#fff').show();
}
}
This keeps every css element originally present and plays my gif in both internet explorer and all other browsers. Thanks!

Hyperlink in JQuery Only Working in JSFiddle

I found something that can not only toggle on/off an image, but also make that image a link.
Problem: It only works in JSFiddle.
I put everything back into html (providing script) and made sure that everything was the same...but still, on my site it won't work. On JSFiddle, it does.
If anyone has a solution, I'd be most grateful.
The code I'm using for the site:
<center>
<p>
<div class="icon-container">
<a id="TOURBUTTON">
<img src="http://static.tumblr.com/6s0fefr/vFQn5uj2h/tournew.png" style="width: 188px; height: 188px;" />
</a>
</div>
</p>
</center>
<center>
<p>
<div class="display-container">
<img id="T5" style="display:none;" a href="http://music.britrodriguez.com" src="http://static.tumblr.com/6s0fefr/GXHnabnep/tahoeshow.png"/>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('#TOURBUTTON').on("click", function(){
$('#T5').toggle();
});
});
$('#T5').click(function(event){
var link = $(this);
var target = link.attr("target");
if ($.trim(target).length > 0){
window.open(link.attr("href"), target);
} else {
window.location = link.attr("href");
}
event.preventDefault();
});
</script>
<style type="text/css">
.icon-container{
display:inline-block;
margin-bottom: 0px;
margin-top: 10px;
}
</style>
The JSFiddle:
http://jsfiddle.net/ccymzmvn/
The site it's not working on:
http://www.britrodriguez.com/HITEST

Why do you open the url with JavaScript? Just try:
<a href="http://music.britrodriguez.com">
<img src="http://static.tumblr.com/6s0fefr/GXHnabnep/tahoeshow.png" />
</a>

These are just suggestions, but:
Make sure your HTML document is well formed and remove extraneous levels. The deeper the DOM tree goes, the "heavier" the page can get for the browser. Always strive towards a shallow DOM tree
The event handler when you click #T5 doesn't really need jQuery, I've used native JS, you can see it has a one to one drop-in.
Whenever you have a click event on an element, change the cursor for the user so they know it is clickable.
I have also user opacity to hide the #T5 instead of display. That way you can make it fade nicely

Css hover text information

I need some help!
I'm doing website, and i'm having a problem with a thing. I have a <h1> and a image next to it, that image is a question mark. And i want that when i mouse hover that question mark it appears the div that i made with the information... i saw lots of topics answered in that forum but none of them is working, pls help me!
<html>
<body>
<h1>branch<img id="help" src="Questionmark.png"></img></h1>
<div id="information">Branch is...</div>
<script>
var e = document.getElementById('help');
e.onmouseover = function() {
document.getElementById('information').style.display = 'block';
}
e.onmouseout = function() {
document.getElementById('information').style.display = 'none';
}
</script>
</body>
</html>
Pls tell me what to do, maybe there is a easy way... i tried css but also didn't work...

I suggest to go with css.
If you are doing layout, use CSS, if you are setting the look and feel
use CSS, if your doing animation use CSS3
If you attach event handlers or reacting to user input use JavaScript.
Note that people use JavaScript instead of CSS for browser support.
There are other solutions like emulating CSS features using
javascript.

css
#information{
display:none;
}
h1:hover + #information{
display:block;
}
fiddle

If you want simple tooltip kind of thing, then you can use this code
<h1>
branch<img id="help" src="Questionmark.png"></img>
<div id="information">Branch is...</div>
</h1>
h1{
position: relative;
}
h1 img{
cursor: pointer;
}
#information{
display: none;
position: absolute;
left: 50px;
width: 100px;
height: 50px;
font-size: 14px;
background: red;
}
h1 img:hover + #information{
display: block;
}
