Unwanted HTML element flickering

I was working on a quick pen for a project when I ran into flickering issues when dragging an element across an image I'm using. Not really sure whats going on here, the problem doesn't seem to occur when you initially load the pen and pan over it the first time, but after that it starts bugging out.

});
$('#crowd').mouseleave(function(){
$('.tagging').attr('class', 'tagger');

$(document).bind('mousemove', function(e){
$('.tagger').css({

top: e.pageY - 55
});
});
$('#crowd').hover(function(){
$('.tagger').show();
});
$('#crowd').mouseleave(function(){
$('.tagging').attr('class', 'tagger');
$('.tagger').hide();
});
$('#crowd').click(function(){
$('.tagging').attr('class', 'tagger');
});
$('.tagger').click(function(){
$('.tagger').attr('class', 'tagging');
});
$(document).on('click', '.tagging li', function(){
alert($(event.target).text());
});

The hover effect consider the cursor and actually your are moving an element with the cursor so what's happening is this:
You start inside the .tagger element and everything is ok as the cursor is on the .tagger element. No event on the #crowd as the cursor never touched/hovered the #crowd until now.
Once you click or you do something that bring the cursor on #crowd you trigger the hover effect which mean that if you leave you will trigger the mouseleave!
So you hover again on the element .tagger and you trigger the mouseleave as expected.
The element disappear (because of what written in the handler of mouseleave) and the cursor is now on #crowd and you trigger again the hover!
The element .tagger appear again, the cursor is on it and you trigger the mouseleave of #croud and so on ...
The flicker is the infinite sequence (4) (5) (4) (5) (4) ...
To fix this you may change the logic as follow. No need to apply the hide/show function, you can simply wrap the image and .tagger element inside the same wrapper and apply overflow:hidden then keep only the click events.
Here is the full code (I made the image smaller so we can see it in the reduced snippet)
$(document).bind('mousemove', function(e){
$('.tagger').css({
left: e.pageX - 55,
top: e.pageY - 55
});
});
$('#crowd').hover(function(){
$('.tagging').attr('class', 'tagger');
});
$('.tagger').click(function(){
$('.tagger').attr('class', 'tagging');
});
$(document).on('click', '.tagging li', function(){
alert($(event.target).text());
});

You are assuming .tagger is JUST the border you've drawn. In actuality, there is an invisible box there. The invisible box is on top of #crowd. When .tagger loads, you are no longer hovering over #crowd, you are hovering over .tagger, which is hovering over #crowd.
To fix it, you may change .tagger from one large box around the mouse, to 4 skinny boxes, so that there is nothing directly below the mouse.

You continuously hide() and show() .tagger repeatedly. mouseleave hides and :hover shows.
there are two ways to fix this:
move the mouseover effect inside the #crowd .hover()
this makes the movement a bit shuddery
see this Pen enter link description here
delete the .delete() call within the .mouseleave handler
Also, a note: The jQuery .hover() method takes two callbacks:
1. for the mouseenter
2. for the mouseleave
So the code could be changed a bit in that regard too.

Mouseover Mouseout with overlapping content

When I mouseover the div with class=background (the little green square in the demo) I fade in the div with class=hover (displaying the grey and blue divs in the demo).
The grey partially overlaps the .background and I can move the mouse around inside it without triggering the mouseout on .background.
But..
If I move the mouse outside the grey div (to hover over the blue for example) then the mouseout on .background gets triggered.
How can I prevent this from happening so that as long as I am hovering over the newly displayed .hover div the mouseout on '.background' will not be triggered?
$('.AddDiv').on('click', function() {
var html = '<div class="container"><div class="background"></div><div class="hover"></div></div>';
$('.Wrap').prepend(html);
});
$(".Wrap").on("mouseover", ".background", function() {
$(this).next(".hover").fadeIn(500);
});
$(".Wrap").on("mouseout", ".hover", function() {
$(this).fadeOut(200);
});
.Wrap {
width: 650px;
height: 800px;
}
.container {
position: relative;
top: 5px;
left: 5px;
width: 200px;
height: 200px;
background-color: red;
float: left;
margin-left: 5px;
margin-top: 5px;
}
.AddDiv {
position: absolute;
top: 0px;
}
.background {
width: 20px;
height: 20px;
background-color: green;
position: absolute;
left: 170px;
top: 10px;
}
.content {
width: 170px;
height: 120px;
background-color: grey;
position: relative;
left: 15px;
top: 15px;
}
.navigation {
width: 190px;
height: 40px;
background-color: blue;
position: relative;
top: 30px;
left: 5px;
}
.hover {
width: 200px;
height: 200px;
background-color: rgba(255, 255, 255, 0.8);
position: absolute;
z-index: 1001;
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="Wrap">
<div class="container">
<div class="background"></div>
<div class="hover">
<div class="content"></div>
<div class="navigation"></div>
</div>
</div>
</div>
<button class=AddDiv>AddDiv</button>

Use mouseleave instead of mouseout:
$('.AddDiv').on('click', function() {
$('.Wrap').prepend($('<div class="container"><div class="background"></div><div class="hover"></div></div>'));
});
$(".Wrap").on("mouseover", ".background", function () {
$(this).next(".hover").fadeIn(500);
});
$(".Wrap").on("mouseleave", ".hover", function () {
$(this).fadeOut(200);
});

Hide/ show div outline

How can i show and hide div outline? I want the content inside the div to display at all times but the outline of the div display only on mouseover.
function show_sidebar() {
document.getElementById('boxes').style.visibility = "visible";
}
function hide_sidebar() {
document.getElementById('boxes').style.visibility = "hidden";
}
.container5 {
background-color: transparent;
width: 220px;
height: 320px;
margin: auto;
top: 0;
right: 0;
bottom: 0;
left: 0;
border: 1px solid red;
position: absolute;
overflow: hidden;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="wrapper" onMouseOver="show_sidebar()" onMouseOut="hide_sidebar()">
<div class="container5" id="boxes">some thing</div>
</div>

The simplest way to achieve what you want is by using just CSS:
#boxes {
border-color: transparent;
}
#wrapper:hover #boxes {
border-color: red;
}
Snippet:
.container5 {
background-color: transparent;
width: 160px; /* resized it to fit inside the screen */
height: 200px; /* resized it to fit inside the screen */
margin: auto;
top: 0;
right: 0;
bottom: 0;
left: 0;
border: 1px solid;
position: absolute;
overflow: hidden;
}
#boxes {
border-color: transparent;
}
#wrapper:hover #boxes {
border-color: red;
}
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="wrapper">
<div class="container5" id="boxes">some thing</div>
</div>
Alternatively, you can use JavaScript to set the border-color property to transparent on mouseout and back to red on mouseover:
JavaScript:
document.getElementById('wrapper').onmouseover = function () {
document.getElementById('boxes').style.borderColor = "red";
}
document.getElementById('wrapper').onmouseout = function () {
document.getElementById('boxes').style.borderColor = "transparent";
}
jQuery:
$("#wrapper").hover(function() {
$("#boxes").css("border-color", "red");
},
function() {
$("#boxes").css("border-color", "transparent");
});
Snippet:
$("#wrapper").hover(function() {
$("#boxes").css("border-color", "red");
},
function() {
$("#boxes").css("border-color", "transparent");
});
.container5 {
background-color: transparent;
width: 160px; /* resized it to fit inside the screen */
height: 200px; /* resized it to fit inside the screen */
margin: auto;
top: 0;
right: 0;
bottom: 0;
left: 0;
border: 1px solid transparent;
position: absolute;
overflow: hidden;
}
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="wrapper">
<div class="container5" id="boxes">some thing</div>
</div>

You can either use a separate class to conditionally toggle it, or use the :hover property. In the interest of JavaScript, I'll show the former. Demo: https://jsfiddle.net/h8c33x9d/
CSS
.container5 {
background-color: transparent;
width: 220px;
height: 320px;
margin: auto;
top: 0;
right: 0;
bottom: 0;
left: 0;
border: 1px solid red;
position: absolute;
overflow: hidden;
}
.my-border {
border: 1px solid red;
}
JavaScript
function show_sidebar() {
$('#boxes').addClass('my-border');
}
function hide_sidebar() {
$('#boxes').removeClass('my-border');
}

You don't need Javascript for that, as suggested by #KarthikeyanSekar, you only need a :hover effect to your container element.
An example to help you visualize can be found on this fiddle, but essentially it goes like this:
The css:
/* Remove the border from the .container5 style */
.container5 {
background-color: transparent;
width: 220px;
height: 320px;
margin: auto;
top: 0;
right: 0;
bottom: 0;
left: 0;
position: absolute;
overflow: hidden;
}
/* Add only the border when the mouse is hover it */
.container5:hover {
border: 1px solid red;
}
And the HTML remains the same, only removing the javascript binds:
<div id="wrapper">
<div class="container5" id="boxes">some thing</div>
</div>
Hope it helps,
Cheers!

/*Change border to transparent */
.container5 {
background-color: transparent;
width: 220px;
height: 320px;
margin: auto;
top: 0;
right: 0;
bottom: 0;
left: 0;
position: absolute;
overflow: hidden;
border: 1px solid transparent;
}
/*Add border color*/
.container5:hover {
border: 1px solid red;
}

jQuery Image Slider Cover Image Positioning Issue

I'm currently making a jquery image slider of 2 images where you can slide left or right to see the before and after photos. I have everything i want set except for the position of the cover image. About 40% of the cover image seems to shift off to the right of the border but the 2nd image is position perfected inside the border. Please advise on how I can put my cover image inside the border perfectly like my 2nd image.
HTML:
<div class="con">
<img src="warming1.jpg" class="imageOne">
<div class="coverImage"></div>
<div class="handle"></div>
<script type="text/javascript">
$(".handle").draggable({
axis: "x",
containment: "parent",
drag: function () {
var position = $(this).position();
var positionExtra = position.left + 6;
$(".coverImage").width(positionExtra + "px");
}
});
</script>
</div>
CSS:
.con {
top:2140px;
left:10px;
width: 280px;
height: 230px;
border: 2px solid;
position: absolute;
z-index:1
}
.con img {
height: 100%;
position: absolute;
}
.coverImage {
position: absolute;
background: url("warming2.jpg");
background-size: auto 100%;
width: 100%;
height: 100%;
}
.handle {
width: 0px;
height: 100%;
border-left: 12px solid #fff;
position: absolute;
left: 50%;
}
.handle:after {
content: "DRAG";
display: block;
width: 60px;
height: 60px;
border: 2px solid #eee;
border-radius: 50%;
color: #999;
line-height: 60px;
font-weight: 300;
text-align: center;
background: #fff;
position: absolute;
left: -36px; top: 0; bottom: 0;
margin: auto;
}

Positioning Picture 1 within the Element containing the border:
Obtain width of element with the border
Obtain width of 2nd picture
Set pic1.width = borderElement.width - pic2.width
Position pic1 at borderElement.right - pic1.width

Move jquery resizable handles out of the divs

I have 3 divs. One inside the other.
jQuery
$(function() {
$("#div1").resizable({
handles: "n, e, s, w, nw, ne, sw,se"
});
$("#div1").draggable();
});
HTML
<div id="div1" style="left: 2px; top: 2px; z-index: 2; width: 100px; height: 70px; background-color: black">
<div id="div2" style="width: 100%; height: 100%; background-color: green; position: absolute;">
<div id="div3" style="width: 90px; height: 60px; position: relative; top: 50%; margin: -30px auto auto; border: 1px dashed rgb(0, 0, 0);">
text
</div>
</div>
</div>
CSS
.ui-resizable-handle { width: 10px; height: 10px; background-color: #ffffff; border: 1px solid #000000; }
.ui-resizable-n { top: 1px; left: 50%; }
.ui-resizable-e { right: 1px; top: 50%; }
.ui-resizable-s { bottom: 1px; left: 50%; }
.ui-resizable-w { left: 1px; top: 50%; }
.ui-resizable-nw { left: 1px; top: 1px; }
.ui-resizable-ne { top: 1px; right: 1px; }
.ui-resizable-sw { bottom: 1px; left: 1px; }
As you can see the div1 is resizable,draggable and has absolute width and height. Div2 has 100% width and height and has absolute position. Div3 has the parameters to be centered horizontally and vertically.
I have a screenshot of what i want to do. I want the white handles to be outside the div like shown in the screenshot. The second div must stay with position:absolute. There is also a jsfiddle that contains my current code.
Please help me move the handles outside of the div.

I'm not sure if I understand your question.
But there is a Fiddle.
I've change only your css.

You need to move the handle's by more than you have in the css you've outlined. I've tidied it up a bit and you can see that here
.ui-resizable-handle {
width: 10px;
height: 10px;
background-color: #ffffff;
border: 1px solid #000000;
}
.ui-resizable-n, .ui-resizable-s {
left:50%;
}
.ui-resizable-e, .ui-resizable-w {
top:50%;
}
.ui-resizable-se {
right: -5px;
bottom: -5px;
}
