How to style a div underneath another div in a fluid layout

I have a somewhat complex HTML/css combination that I want to achieve. I can have any number of divs in a row and each of them will have some information pertaining to that div. The divs are represented as the red boxes in my picture.
Each div will have its own blue box that I want to be within it via HTML but display below it via css. This blue box should only be displayed when the div is clicked, should appear beneath the div (and all others in that row but ABOVE all the divs in the next row), and should span the entire width of the parent container (so it will be the width of the 5 red divs in this picture). Is anything like this possible? I can't think of a way to really do anything like this. I've created a fiddle with a quick mock up that you can alter: https://jsfiddle.net/hL8r9fu9/
.wrapper {
width:500px;
background:white;
height:500px;
}
.item {
float:left;
width: 18%;
margin-right:2%;
height:120px;
background:red;
margin-bottom:2%;
}
.info {
height:20px;
background:blue;
}
.info.is-hidden {
display:none;
}

One way you can determine the items in a row against in another row is to use .offset().top on the elements ( since the value would return same for all div in the same row ).
$(document).ready(function(){
$(".item").each(function(){
var $this = $(this);
$this.click(function(){
$this.find(".info").toggleClass("is-hidden");
if($this.offset().top > 10) // just an example value , you need to adjust this .
$this.find(".info").css("top","0%");
});
});
});
Working example : https://jsfiddle.net/DinoMyte/hL8r9fu9/3/

I was able to do this with the following jquery code:
$('.inherit-wrapper').each(function( element ) {
var $this = $(this),
property = $this.attr('wrapper-property'),
value = $this.parent().parent().css(property);
if(property && value) $this.css(property, value);
});
See the fiddle. I borrowed the function from this fiddle by iConner.

I messed with your jsfiddle and here is what I got. You will have to tweak it to get what you want, but you can see where I was going with it.
html is the same and tweaked css a bit.
js:
$(document).ready(function(){
$(".item").click(function(){
var $this = $(this);
var info = $this.find(".info");
var infoTopPos = $this.offset().top;
var infoHeight = $this.height();
var parentWidth = $this.parent().width();
var parentLeftPos = $this.parent().offset().left;
$(".info").not(info).addClass('is-hidden');
$(info).toggleClass('is-hidden');
info.css({width: parentWidth, top: (infoTopPos+infoHeight)+'px', left: parentLeftPos});
});
});

Replace image on hover

I'm trying to replace an image with another image.
Since the webpage, that i'm building, has to be viewable in IE8, then CSS based solutions played out quircky.
I tried the
display: none; and display: block; trick
opacity: 0; and opacity: 1; trick
But they both don't function as I want to (centered inside a div, because IE8 plays some stuff differently, then I thought that may-be a simple src="" swaping will do the trick.
I started with jquery, but since I'm pretty bad with understanding the $(this) and DOM, then it isnt working at all, but i think I got my logic right.
So, HTML is here:
<div class="wrapper">
<a href="#">
<img class="original" src="http://placekitten.com/200/200">
<img class="overlay" src="http://placekitten.com/g/200/200">
</a>
…
…
So I have numerous a tags inside a wrapper, each containing two images. As they are responsive and having the same ratio, then no sizes are needed.
And my started jquery:
$('.wrapper a').hover(
function () {
var original = $(this).attr('src');
var overlay = $(this).next().attr('src');
$(this).children('.original').attr('src', overlay);
},
function () {
$(this).children('.original').attr('src', original);
}
);
And here's the JSFiddle .
So, I'm really after this, that each a tag I have inside a wrapper would change the image according to the images inside of that tag.

You don't need javascript here at all. Really. Use CSS:
.wrapper a:hover .original {
display: none;
}
.wrapper a:hover .overlay {
display: inline-block;
}
Demo: http://jsfiddle.net/hHyh6/10/

You should simply show overlay image on hover and hide original image
$('.wrapper a').hover(function () {
$(this).find('.original').toggle();
$(this).find('.overlay').toggle();
}, function () {
$(this).find('.original').toggle();
$(this).find('.overlay').toggle();
});
DEMO

Instead you can try this:
$('.overlay').hide(); //<----------first hide the overlay image
$('.wrapper a').hover(function () {
$(this).find('.overlay').show().add(this).find('.original').hide();
// here find the overlay and show it and hide the original
}, function () {
$(this).find('.overlay').hide().add(this).find('.original').show();
// here find the overlay and hide it and show the original
});
Demo # Fiddle using .end()
Demo # Fiddle using .add(this)

try this js i also tried in your fiddle too it works
var current_cash;
$('.wrapper a').hover(
function () {
current_cash = $(this).find('.original').attr('src');
var overlay = $(this).find('.overlay').attr('src');
$(this).children('.original').attr('src', overlay);
},
function () {
$(this).children('.original').attr('src', current_cash);
}
);

Showing a div onmouseover for table row, and setting text and URL dynamically using row attributes

I'm working on a pricing comparison table, and wanted to display more information on each option in a different way.
When a user hovers their mouse over a row, I want the row to show more information on that feature. I now have this working using jQuery and a div.
$(document).ready(function() {
$('#row').mouseover(function() {
var $divOverlay = $('#divOverlay');
var bottomWidth = $(this).css('width');
var bottomHeight = $(this).css('height');
var rowPos = $(this).position();
bottomTop = rowPos.top;
bottomLeft = rowPos.left;
$divOverlay.css({
position: 'absolute',
top: bottomTop,
left: bottomLeft,
width: bottomWidth,
height: bottomHeight
});
$divOverlay.text($(this).closest('tr').attr('desc'));
$divOverlay.delay('100').fadeIn();
$(this).closest('tr').css({ opacity: 0.01 });
});
$('#divOverlay').mouseleave(function() {
var $divOverlay = $('#divOverlay');
$('#row').css({ opacity: 1 });
$divOverlay.fadeOut();
});
});
My problem now lies in that in some cases I want to include a link to a video, or another page (that opens in a new tab) - to provide the user with more information if needed. But the way I have this working, the link isn't rendered as html but shown as text instead. Would anyone know how else I could do this?
Full functional example:
http://jsfiddle.net/rMXAp/1/
Another idea I had was setting an onclick for the div, where the href is taken from the "desc_link" attribute (see non-header row in jsfiddle example), but I'm not sure yet on how I can set this with jQuery.
I think it was somthing similar to the following that I tried:
$divOverlay.setAttribute('onclick',$(this).closest('tr').attr('desc_link'));
Suggestions are appreciated!

Try using .html instead of .text - should do the trick :)

Scroll event background change

I am trying to add a scroll event which will change the background of a div which also acts as the window background (it has 100% width and height). This is as far as I get. I am not so good at jquery. I have seen tutorials with click event listeners. but applying the same concept , like, returning scroll event as false, gets me nowhere. also I saw a tutorial on SO where the person suggest use of array. but I get pretty confused using arrays (mostly due to syntax).
I know about plugins like waypoints.js and skrollr.js which can be used but I need to change around 50-60 (for the illusion of a video being played when scrolled) ... but it wont be feasible.
here is the code im using:-
*
{
border: 2px solid black;
}
#frame
{
background: url('1.jpg') no-repeat;
height: 1000px;
width: 100%;
}
</style>
<script>
$(function(){
for ( i=0; i = $.scrolltop; i++)
{
$("#frame").attr('src', ''+i+'.jpg');
}
});
</script>
<body>
<div id="frame"></div>
</body>

Inside your for loop, you are setting the src attribute of #frame but it is a div not an img.
So, instead of this:
$("#frame").attr('src', ''+i+'.jpg');
Try this:
$("#frame").css('background-image', 'url(' + i + '.jpg)');
To bind a scroll event to a target element with jQuery:
$('#target').scroll(function() {
//do stuff here
});
To bind a scroll event to the window with jQuery:
$(window).scroll(function () {
//do stuff here
});
Here is the documentation for jQuery .scroll().
UPDATE:
If I understand right, here is a working demo on jsFiddle of what you want to achieve.
CSS:
html, body {
min-height: 1200px; /* for testing the scroll bar */
}
div#frame {
display: block;
position: fixed; /* Set this to fixed to lock that element on the position */
width: 300px;
height: 300px;
z-index: -1; /* Keep the bg frame at the bottom of other elements. */
}
Javascript:
$(document).ready(function() {
switchImage();
});
$(window).scroll(function () {
switchImage();
});
//using images from dummyimages.com for demonstration (300px by 300px)
var images = ["http://dummyimage.com/300x300/000000/fff",
"http://dummyimage.com/300x300/ffcc00/000",
"http://dummyimage.com/300x300/ff0000/000",
"http://dummyimage.com/300x300/ff00cc/000",
"http://dummyimage.com/300x300/ccff00/000"
];
//Gets a valid index from the image array using the scroll-y value as a factor.
function switchImage()
{
var sTop = $(window).scrollTop();
var index = sTop > 0 ? $(document).height() / sTop : 0;
index = Math.round(index) % images.length;
//console.log(index);
$("#frame").css('background-image', 'url(' + images[index] + ')');
}
HTML:
<div id="frame"></div>
Further Suggestions:
I suggest you change the background-image of the body, instead of the div. But, if you have to use a div for this; then you better add a resize event-istener to the window and set/update the height of that div with every resize. The reason is; height:100% does not work as expected in any browser.

I've done this before myself and if I were you I wouldn't use the image as a background, instead use a normal "img" tag prepend it to the top of your page use some css to ensure it stays in the back under all of the other elements. This way you could manipulate the size of the image to fit screen width better. I ran into a lot of issues trying to get the background to size correctly.
Html markup:
<body>
<img src="1.jpg" id="img" />
</body>
Script code:
$(function(){
var topPage = 0, count = 0;
$(window).scroll( function() {
topPage = $(document).scrollTop();
if(topPage > 200) {
// function goes here
$('img').attr('src', ++count +'.jpg');
}
});
});
I'm not totally sure if this is what you're trying to do but basically, when the window is scrolled, you assign the value of the distance to the top of the page, then you can run an if statement to see if you are a certain point. After that just simply change run the function you would like to run.
If you want to supply a range you want the image to change from do something like this, so what will happen is this will allow you to run a function only between the specificied range between 200 and 400 which is the distance from the top of the page.
$(function(){
var topPage = 0, count = 0;
$(window).scroll( function() {
topPage = $(document).scrollTop();
if(topPage > 200 && topPage < 400) {
// function goes here
$('#img').attr('src', ++count +'.jpg');
}
});
});

Javascript - fading from one item to another pops up with both briefly

I have a testimonials area on my website that fades from one testimonial to another. I'm having an issue where it will fade out too slowly before the next item fades in causing both to come up making a large div making it look ugly.
I want it to fade from one testimonial to another without jumping and flashing with both.
You can see an example here: http://ledragonvert.com/index_test.php
Here is my Javascript code:
function rotate_p() {
if (p_current == p_count) {
p_current = 1;
} else {
p_current++;
}
var $container = $('#container');
$container.find('p').fadeOut();
$container.find('p:nth-child(' + p_current + ')').fadeIn();
}
var p_count;
var p_current = 0;
var p_interval;
$(document).ready(function () {
rotate_p();
p_count = $('#container').find('p').length;
p_interval = setInterval(function () {rotate_p();}, 7000);
});
Thanks you very much for taking your time out to help me.

the solution is CSS based. since the position of the "p" element is static and you call both fadeOut and fadeIn, there is an overlap, as two p elements are inevitably shown together. To get them one on top of the other you need to use absolute positioning on the p element, like so:
#container {
position:relative;
}
#container>p {
position:absolute;
//use any values you wish, to set the testimonial relative to #container:
top:10px;
left:50px;
}
