Background-image transition not woking in Firefox (-moz-)

I dont get the fade of the background picture to work in Firefox but any other Browser. Help is appreciated!
Just click on the image.
$(document).ready(function(){
$(".click_me").click(function(){
$('.click_me').css('background-image', 'url(https://placekitten.com/500/500)');
});
});
.click_me {
height:500px;
width:500px;
opacity: 1.0;
background-image: url(http://placekitten.com/g/500/500);
-webkit-transition: background-image 700ms linear;
-moz-transition: background-image 700ms linear;
-o-transition: background-image 700ms linear;
-ms-transition: background-image 700ms linear;
transition: background-image 700ms linear;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="click_me"></div>

Since you are using jQuery already why don't use its animate function instead of CSS transitions, this will do the trick for you very easily.
$(document).ready(function() {
$(".click_me").one('click', function() {
$(this).animate({
opacity: 0
}, 'fast', function() {
$(this)
.css({
'background-image': 'url(https://placekitten.com/500/500)'
})
.animate({
opacity: 1
});
});
});
});
.click_me {
height: 500px;
width: 500px;
opacity: 1.0;
background-image: url(http://placekitten.com/g/500/500);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="click_me"></div>

jquery css background image slideshow with transtion effect

I need to add some nice transition fade effect to the change of the following simple sideshow:
var images = [
"http://static1.squarespace.com/static/550b669de4b0d91b0f49935d/t/551b6575e4b0c2174c3a6f54/1427858806833/flowers.jpg?format=1500w",

"http://www.ninthstreetflowers.com/smp/Smp1/images/flower4.jpg",
"http://magic-spells-and-potions.com/images/flower-language-vertical.png",
];
var i = 0;
var div;
$(function() {
div = $('.header_summer');
console.log("loaded");
setTimeout(changeBack, 1000);
});
function changeBack() {
i = ++i % images.length;
if (i > images.length) {
i = 0;
}
console.log('url("' + images[i] + '");');
// div.css('background-image', "url('" + images[i] + "')");
// preload image check
//
$('<img/>').attr('src', images[i]).load(function()
{
$(this).remove();
$('.header_summer').css('background', 'url("' + images[i] +'") no-repeat 0px 0px');
});
//
setTimeout(changeBack, 5000);
}
.header_summer {
background: url('../tpl/mblmhv1/images/summer_cover1.jpg') no-repeat 0px 0px;
background-size: cover;
min-height:920px; /* 800px; */
/* TRANSISITION - not qorking here
transition(background-image 0.5s ease-in-out);
transition: opacity 1s ease-in-out;
-webkit-transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-o-transition: opacity 1s ease-in-out;
*/
}
<script src="https://code.jquery.com/jquery-2.1.4.js"></script>
<div class='header_summer'></div>
I have tried appending .fadeIn() to the jquery line that changes the image, and transition effects in the CSS - what am I missing?

Try this:
.header_summer {
background: url('../tpl/mblmhv1/images/summer_cover1.jpg') no-repeat 0px 0px;
background-size: cover;
min-height:920px; /* 800px; */
transition: background-image 0.2s ease-in-out;
}

It should work with just the transition property defined on your CSS class as any changes to the element should trigger the transition (i.e. when you update the background, you should see the transition):
.header_summer {
background: url('http://static1.squarespace.com/static/550b669de4b0d91b0f49935d/t/551b6575e4b0c2174c3a6f54/1427858806833/flowers.jpg?format=1500w') no-repeat 0px 0px;
background-size: cover;
min-height: 920px;
/* Transitions and their cross-browser friends */
-webkit-transition: 1s ease-in-out;
-moz-transition: 1s ease-in-out;
-o-transition: 1s ease-in-out;
transition: 1s ease-in-out;
}
The syntax generally uses the form <property> <duration> <timing-function> <delay>, so your current transition would be looking for the opacity property to change, which it doesn't seem to be.
You should consider using background instead :
transition: background 1s ease-in-out;
-webkit-transition: background 1s ease-in-out;
-moz-transition: background 1s ease-in-out;
-o-transition: background 1s ease-in-out;
Example
.header_summer {
background: url('http://static1.squarespace.com/static/550b669de4b0d91b0f49935d/t/551b6575e4b0c2174c3a6f54/1427858806833/flowers.jpg?format=1500w') no-repeat 0px 0px;
background-size: cover;
min-height: 920px;
-webkit-transition: 1s ease-in-out;
-moz-transition: 1s ease-in-out;
-o-transition: 1s ease-in-out;
transition: 1s ease-in-out;

Javascript Slideshow Glitches When Clicking Empty Space Around Image

So I got this slideshow code working, where when you click an image, it fades into another image. However, if, for example, there was a vertical orientated image with empty space on its right, if you click that space the whole slideshow kind of glitches out.
Here's my website where you can test it out:
http://danielshultz.github.io
The code:
$(document).ready(function() {
$.fn.nextOrFirst = function (selector) {
var next = this.next(selector);
return (next.length) ? next : this.prevAll(selector).last();
};
$("#cf2 img").click(function() {
$(this)
.removeClass('visible')
.nextOrFirst()
.addClass('visible');
});
});
CSS:
#cf2 {
position:relative;
height:281px;
width:450px;
margin:0 auto;
}
#cf2 img {
position:absolute;
left:0;
max-height: 600px;
max-width: 600px;
opacity: 0;
z-index: 0;
-webkit-transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-o-transition: opacity 1s ease-in-out;
transition: opacity 1s ease-in-out;
}
#cf2 img.visible {
opacity: 1;
z-index: 1;
}
HTML:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="cf2" class="shadow">
<img class="visible" src="http://static.ddmcdn.com/gif/storymaker-best-hubble-space-telescope-images-20092-514x268.jpg" alt="1"/>
<img src="http://economictimes.indiatimes.com/thumb/msid-45891755,width-640,resizemode-4/nasas-images-of-most-remarkable-events-you-cant-miss.jpg" alt="2"/>
<img src="http://i.dailymail.co.uk/i/pix/2013/11/03/article-2486855-192ACC5200000578-958_964x682.jpg" alt="3"/>
<img src="http://mstatic.mit.edu/nom150/items/199-HybridImage.jpg" alt="4"/>
</div>

If i understood, the problem here is when you click outside the image but inside the square of the previous image, then the slide does not change.
This approach, makes no changes in yout javascript but changes the html and some selectors.
In the example below, I wrapped each <img> into a '<div>' and changed the selectors to match with those divisions. Minor stylings too.
So, if you click outside the image but over the div, the slide changes as expected.
$(document).ready(function() {
$.fn.nextOrFirst = function (selector) {
var next = this.next(selector);
return (next.length) ? next : this.prevAll(selector).last();
};
$("#cf2 div.holder").click(function() {
$(this)
.removeClass('visible')
.nextOrFirst()
.addClass('visible');
});
});
body {
font-family: verdana;
font-size: 8pt;
color: #000;
}
#cf2 {
position: relative;
height: 600px;
width: 600px;
margin: 0 auto;
}
#cf2 div.holder {
position: absolute;
left: 0;
height: 600px;
width: 600px;
opacity: 0;
z-index: 0;
-webkit-transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-o-transition: opacity 1s ease-in-out;
transition: opacity 1s ease-in-out;
}
#cf2 div.holder img {
max-height: 600px;
max-width: 600px;
}
#cf2 div.holder.visible {
opacity: 1;
z-index: 1;
}
.hidden {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Animated CSS Progress Bar

I have found a neat animated css progress bar but am struggling extending what what it can do. I have it so that I have an animated progress bar but I want to be able to show the actual percentage once the animated bar has completed - to the right of the bar.
Be grateful for any help
CSS
.progress_bar
{
height: 15px;
background: orange;
width: 0%;
-moz-transition: all 4s ease;
-moz-transition-delay: 1s;
-webkit-transition: all 4s ease;
-webkit-transition-delay: 1s;
transition: all 4s ease;
transition-delay: 1s;
}
HTML
<div id="progressBar" class="progress_bar"></div>
JavaScript
// Assign your element ID to a variable.
var progress = document.getElementById("progressBar");
// Pause the animation for 100 so we can animate from 0 to x%
setTimeout(
function(){
progress.style.width = "100%";
// PHP Version:
// progress.style.width = <?php echo round($percentage150,2); ?>+"%";
progress.style.backgroundColor = "green";
}
,100);

I suggest you to insert a hidden element with the percent and show it once the transition is done.
What do you think of this solution ?
// Assign your element ID to a variable.
var progress = document.getElementById("progressBar");
var percent = progress.getElementsByClassName("percent")[0];
// Pause the animation for 100 so we can animate from 0 to x%
setTimeout(
function() {
progress.style.width = "100%";
// PHP Version:
// progress.style.width = <?php echo round($percentage150,2); ?>+"%";
progress.style.backgroundColor = "green";
setTimeout(function() {
percent.style.display = "block";
}, 4100);
}, 100);
.progress_bar {
height: 15px;
background: orange;
width: 0%;
-moz-transition: all 4s ease;
-moz-transition-delay: 1s;
-webkit-transition: all 4s ease;
-webkit-transition-delay: 1s;
transition: all 4s ease;
transition-delay: 1s;
text-align: center;
}
.progress_bar .percent {
display: none;
}
<div id="progressBar" class="progress_bar"><span class="percent">100%</span></div>

You could give a delay on color from transparent to black via rgba()
here a codepen to play with : http://codepen.io/anon/pen/QwRRGG
// Assign your element ID to a variable.
var progress = document.getElementById("progressBar");
// Pause the animation for 100 so we can animate from 0 to x%
setTimeout(
function() {
progress.style.width = "100%";
// PHP Version:
// progress.style.width = <?php echo round($percentage150,2); ?>+"%";
progress.style.backgroundColor = "green";
progress.style.color = "rgba(0,0,0,1)";
}, 100);
.progress_bar {
height: 15px;
background: orange;
width: 0%;
-moz-transition: background-color 4s ease, width 4s ease , color 0s 4s;
-webkit-transition: background-color 4s ease, width 4s ease , color 0s 4s;
transition: background-color 4s ease, width 4s ease , color 0s 4s;
color:rgba(0,0,0,0);
text-align:right
}
<div id="progressBar" class="progress_bar">100%</div>

Fade one image into another using css or jquery

I need to be able to fade in a second image above the initial image on hover. I need to make sure that second image isn't visible initially until it fades in. The other important note is that neither of the images should fade out entirely at any time. I've tried several approaches such as using 1 image, 2 images, jquery animate and css transition.
I've read that it is possible to animate a change of attribute using jquery? If this is true, how could I animate the change of 'src' in img using jquery?
$(".image").mouseenter(function() {
var img = $(this);
var newSrc = img.attr("data-hover-src");
img.attr("src",newSrc);
img.fadeTo('slow', 0.8, function() {
img.attr("src", newSrc);
});
img.fadeTo('slow', 1);
}).mouseleave(function() {
var img = $(this);
var newSrc = img.attr("data-regular-src");
img.fadeTo('slow', 0.8, function() {
img.attr("src", newSrc);
});
img.fadeTo('slow', 1);
});
This is what i'm currently using. It's the closest i've gotten. But you can see the image change which is not desirable.

Using a single html element with background images
HTML - doesn't get simpler than this
<div id="imgHolder"></div>
CSS
#imgHolder {
width: 200px;
height: 200px;
display: block;
position: relative;
}
/*Initial image*/
#imgHolder::before {
content:"";
top: 0;
left: 0;
bottom: 0;
right: 0;
position: absolute;
background-image:url(http://placehold.it/200x200);
-webkit-transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-o-transition: opacity 1s ease-in-out;
transition: opacity 1s ease-in-out;
z-index:10;
}
#imgHolder:hover::before {
opacity:0;
}
#imgHolder::after {
content:"";
background: url(http://placehold.it/200x200/FF0000);
top: 0;
left: 0;
bottom: 0;
right: 0;
position: absolute;
z-index: -1;
}
Demo
OR if you want to use image tags...
Stealing straight from: http://css3.bradshawenterprises.com/cfimg/
HTML
<div id="cf">
<img class="bottom" src="pathetoImg1.jpg" />
<img class="top" src="pathetoImg2.jpg" />
</div>
CSS
#cf {
position:relative;
height:281px;
width:450px;
margin:0 auto;
}
#cf img {
position:absolute;
left:0;
-webkit-transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-o-transition: opacity 1s ease-in-out;
transition: opacity 1s ease-in-out;
}
#cf img.top:hover {
opacity:0;
}
There are many other examples in the link as well to play with, but this will get you started.
Final Opacity
You've mentioned you don't want the initial image to disapear comletely. To do this change opacity:0 to opacity:0.5 or something similar. You'll need to experiment with that value to get the result you want.
Demo with final opacity of 0.8
Dynamic Image Sizes
I think you will be stuck with the two image version for this if just using CSS. HTML is the same.
CSS
#cf {
position:relative;
}
#cf img {
-webkit-transition: opacity 1s ease-in-out;
-moz-transition: opacity 1s ease-in-out;
-o-transition: opacity 1s ease-in-out;
transition: opacity 1s ease-in-out;
}
#cf img.bottom {
z-index:-1;
opacity:0;
position:absolute;
left:0;
}
#cf:hover img.top {
opacity:0.8;
}
#cf:hover img.bottom {
display:block;
opacity:1;
}
Demo
