Inverse direction of jQuery UI resizable

I have a floating sidebar which is located on the right of the page which I want to be able to resize using a handle on the left of the container.
At the moment, when I drag the sidebar using the handle, it makes the sidebar wider when dragging right, and smaller when dragging left - I wan't it to do the inverse of this. i.e., dragging to the left increases the size of the sidebar etc..
I would prefer to not change the html structure and hopefully have a simple line of javascript to fix the problem - please help!
Here is a fiddle: https://jsfiddle.net/c01gat3/us8vktjq/
html
<div id="sidebar">
<div id="drag">
</div>
</div>
css
#sidebar{
position: absolute;
top: 0;
right: 0;
width: 200px;
height: 100% !important;
background-color: blue;
}
#drag{
position: absolute;
left: -10px;
width: 10px;
height: 100%;
background-color:black;
cursor:ew-resize;
}
Javascript
$('#sidebar').resizable({
minWidth: 100,
handles: { "w" : $("#drag") }
});

You're missing the associated CSS file.
Add the following reference to your HTML page:
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
Adjust your HTML code to include the needed classes:
<div id="sidebar">
<div id="drag" class="ui-resizable-handle ui-resizable-w">
</div>
</div>

How to position a div above another div?

My code is:
HTML:
<section>
<div id="banner">
<div class="container">
<p class="para">hello world</p>
</div>
<div class="container banner-bottom">
<div class="card card-primary text-center z-depth-2 contact-main-text">
<div class="card-block">
<p class="white-text">Please fill out the form below and ESC
staff will be in contact with you shortly.</p>
</div>
</div>
</div>
</div>
</section>
CSS:
.para{
color:white;
background: red;
padding:70px;
text-align:center;}
.white-text{
background:green;
padding:20px;}
Output is: Bootply
And i want:
Could anyone help me with that?

You can set negative top margin to overlay the second div, see the live example:
<div class="container banner-bottom" style="margin-top:-5%;padding:2%">
http://www.bootply.com/MorC45NB4V
PS: I have used inline css just to show, avoid inline css.

My solution uses jQuery and some calculations. My calculation works even if you move the elements around the document. I also used CSS for the margins you wanted.
jQuery
//location of bottom of the red container
var bottomOfContainer = $('#onTopOfMe').offset().top + $('#onTopOfMe').height();
//gets the bottom 4th of the red container
var placement = bottomOfContainer - ($('#onTopOfMe').height() / 4);
//setter of top for green container
$('#placeMe').offset({"top": placement});
CSS
p.white-text{
margin-left:5%;
margin-right:5%;
}
Output
bootply

1) In case you want your lower banner to have a full width:
You could add position: relative; to the lower banner and position it adding a bottom value and use margin to create the same visual effect asked in the question.
.banner-bottom {
position: relative;
bottom: 45px;
margin: 0 40px;
}
2) In case you don't need to have a banner with full width and just center it, then no need to use margins. Remember to set one parent as position: relative;:
#banner { position:relative;}
.banner-bottom {
position: absolute;
top:75%;
right:0;
bottom:auto;
left:0;
}
CODEPEN

Here's my solution for this.
Basically just make the position of the card block "relative", position the "top" position accordingly, then set the margin to "auto" to center it.
.card-block {
position: relative;
top: -50px;
margin: auto;
width: 80%;
}

A bit of position could help you, here's a rough version that will hopefully get you thinking what you need to do:
#banner { position:relative;}
.banner-bottom { position: absolute; top:75%;right:0;bottom:auto;left:0; }

Make Div fixed bottom & scrollable

I want to have a long page, with a fixed top 100px div, and a fixed 50px bottom div. However, I want the bottom div to scroll as you scroll down the page.
Its hard to explain, but the best example of this is on the front page of PayPal.com
On the first page load, the bottom div looks like it is fixed, and as you adjust the height of the browser window, that div stays at the bottom. Yet as you scroll down the page it is not fixed.
Can anyone explain how they have done this? I am trying to re-create something similar, but cant see how they have managed it.
As far as I can see they have this html...
<div id="fixed-top">
<header class="table-row">
// header content
</header>
<div class="table-row table-row-two">
// Video content
</div>
<div class="table-row">
//bottom content
</div>
</div>
And this CSS...
#fixed-top {
height: 100%;
width: 100%;
display: table;
position: relative;
top: 0;
left: 0;
z-index: 1;
}
.table-row {
display: table-row;
}
But that alone doesn't do it. I also can't see any js thats getting window height and applying it to the main fixed div.
Help! :)
EDIT:
Have just found a way to do it with javascript, controlling the height of the middle row using the window height, minus the 150px for the header and third row.
jQuery(document).ready(function(){
$('div.table-row-two').css({'height':(($(window).height())-150)+'px'});
$(window).resize(function(){
$('div.table-row-two').css({'height':(($(window).height())-150)+'px'});
});
});
But saying that, Zwords CSS only method seems like a winner.

From what I understand, you are looking for something like a sticky footer. So basically if the content is not enough, the footer should go sit at the bottom like its fixed, but if content comes in, it should scroll down like other content.
Try this - http://css-tricks.com/snippets/css/sticky-footer/

First off, you'll need to set the height of the body and html tag, otherwise the table won't take the full screen. Then I altered your code, made it a bit easier.
HTML:
<div id="fixed-top">
<header>
// header content
</header>
<div>
// Video content
</div>
<div>
//bottom content
</div>
</div>
CSS:
html, body {
margin: 0;
padding: 0;
height: 100%;
min-height: 100%;
}
#fixed-top {
display: table;
width: 100%;
height: 100%;
}
#fixed-top > * { /* makes all the direct children of #fixed-top a table row*/
display: table-row;
background: lightblue;
}
#fixed-top > *:nth-child(1) {
background: lightgreen;
height: 40px;
}
#fixed-top > *:nth-child(3) {
background: lightgreen;
height: 25%;
}
You can either set the height to a fix height (in px) or percentages. If you only give two of the three rows a height, the third one will automaticly fill up the rest space.
Also, check this demo.

height:100%;
margin:0px auto;
padding:0px;
}
.wrapper{
display:table;
border:1px solid black;
}
.wrapper .row{
display:table-row;
background-color:rgb(220,220,220);
}
.wrapper .row:nth-of-type(1){
min-height:15px;
}
.wrapper .row:nth-of-type(2){
height:100%;
background-color:white;
}
.wrapper .row:nth-of-type(3){
min-height:15px
}

You can do this easily with jQuery using $(window).height() and subtracting your footer/header's heights. See Fiddle for an example.

How to set a position of an element 5px below a fixed position element

Ex: the 1st Div:
<div style='position: fixed; width=100%'> ....</div>
Now i want to put another Div 5px right below the previous Div. So i did
<div style='padding-top:5px; width=100%'> ....</div>
But it didn't work, seem padding-top compare itself to the top of window but not to its previous Div. If i remove the position: fixed; in the 1st div then it will be fine, but i don't want that.
I want the 1st Div got position fixed & the 2nd Div's position is 5px right below the 1st one. So how to do that?

position: fixed removes the element from the regular flow. You can't use flow positioning anymore.
There are likely proper ways to do what you want, but I don't know what you want because you told us about Y, not X: https://meta.stackexchange.com/questions/66377/what-is-the-xy-problem
I think I understand what you want. If you always know how high the header is you can just add an offset, padding and margin should both work.
<div id="header" style="position: fixed; top: 0; width: 100%; height: 20px;">
<div id="content" style="margin-top: 20px;">Content goes here</div>
If the header can change height adjust your CSS so that the header and content change their height and content respectively.
<div id="container" class="adjustheaderheight">
<div id="header">
<div id="content">Content goes here</div>
</div>
#header { position: fixed; top: 0; width: 100%; height: 20px; }
#content { margin-top: 20px; }
#container.adjustheaderheight #header {
height: 40px;
}
#container.adjustheaderheight #content {
margin-top: 40px;
}
If your header changes height dynamically you'll need to change the content offset dynamically although I would strongly advise you not to have a dynamic header.

Have you tried margin-top instead?
margin-top: 5px

You might wanna include both these divisions within another division and make this new outer division position fixed. Like this --->
<div style='position: fixed; width=100%'>
<div style='width=100%'> ....</div>
<div style='padding-top:5px; width=100%'> ....</div>
</div>

put the two divs in a wrapper posioned fixed. Also you have invalid css syntax width=100% must be width:100%.
<div style="position: fixed;">
<div style=' width:100%'> ....</div>
<div style='margin-top:5px; width:100%'> ....</div>
</div>
however, this makes the 2 divs fixed... and this might not be what you want. You could do the following:
<div style='position: fixed; width:100%'> ....</div>
<div style='position:absolute; width:300px;height:200px;top:300px;left:300px'> ....</div>
css values are just for example...
UPDATE:
is this what you want?
http://jsfiddle.net/kasperfish/K8N4f/1/
<div id="fixed">fixed</div>
<div id="widget" >content <br>hjgjhgjhgjhgh</div>
#fixed{
width:100%;
position:fixed;
background:yellow;
height:50px;
z-index:2;
}
#widget{
background:blue;
position: absolute;
top:55px;
margin-top:15px;
width:100%
}

If you have tried Margin and it doesn't work feel free to use padding as long as you don't have a background color or image within the div then you won't be able to tell the difference between the two ways of doing this.

How to stack divs beside each other to create a carousel

I am trying to create a carousel, where clicking on any element will slide it leftwards, simultaneously sliding the right element into viewport. For that, I need to have the divs stacked side by side. I am trying it out as a float based layout (see Fiddle ).
Problem is that here clicking the red colored div slides it leftward alright, but not the green element leftwards. This is probably due to the fact that they are actually lying below another, as visible when the overflow: hidden is removed from #cont's style. How elese to stack them side by side so that sliding one leftward automatically slides the next one leftwards as well? (Creating the to-be-next element on the fly while clicking and animating it into viewport is a no-no, the element should be present in the DOM!)

I'd suggest you use a plugin, as there is more to this than you may realize. There are many plugins out there for this, here's a list to get you started: http://www.tripwiremagazine.com/2012/12/jquery-carousel.html
I modified your Javascript, HTML, and CSS to get you pointed in the right direction:
http://jsfiddle.net/nf5Dh/2/
You need a container contContent, positioned absolutely, and that container gets moved within the container div. You just float the elements in contContent to get them next to each other.
HTML:
<div id='cont'>
<div id="contContent">
<div id='i1'></div>
<div id='i2'></div>
<div id='i3'></div>
</div>
</div>
CSS:
#cont {
width: 50px;
padding-top: 10px;
background: blue;
height: 50px;
overflow: hidden;
position: relative;
}
#contContent {
height: 50px;
width: 150px;
position: absolute;
top: 0;
left: 0;
}
#contContent > div {
float: left;
display: inline-block;
height: 50px;
width: 50px;
}
#i1 { background: red; }
#i2 { background: green; }
#i3 { background: yellow; }
And the JS:
$("#contContent > div").click(function(){
$("#contContent").animate({left: "-=50px"},1000);
});
You'd probably be better off using an ul instead of all divs, this is at least more semantically correct, though not technically necessary.
<div id="carousel">
<ul id="carouselContent">
<li id="slide1"></li>
<li id="slide2"></li>
<li id="slide3"></li>
</ul>
</div>

This:
#cont {
white-space:nowrap;
overflow: hidden;
}
.pane { // or whatever the slide divs are called. get rid of the float.
float: none;
display: inline-block;
*zoom:1;
*display:inline;
}

You can use that carousel where you can generate javascript for the carousel http://caroufredsel.dev7studios.com/configuration-robot.php

I've used http://sorgalla.com/jcarousel/ for things like this in the past, that's based on postion: relative and left/right offsets. Probably easier than messing with floats.

You can try using a list item instead, and display them inline.
