How to change smoothly my div content

I have a pagination that i want to change the content of container by click on it.
it works, but i want that it happen smoothly.
<div id='container>
<div id='0' class='box'></div>
<div id='1' class='box'></div>
<div id='2' class='box'></div>
</div>
style :
#container{'
position:relative
}
.box{
position: absolute;
display: none;
}
.box:first-child{
display: inline-block;
}
by click on my pagination buttons :
$(function () {
var obj = $('#pagination').twbsPagination({
totalPages: 3,
visiblePages: 2,
prev:'Prev',
next:'Next',
onPageClick: function (event, page) {
console.info(page);
page=page-1;
$(".box").hide(function () {
$("#"+page).show();
});
}
});
how can i do this smoothly?

You have 2 options
In Jquery Way:-
Use fadeIn fadeOut in place of show hide
$(".box").fadeOut("slow",function () {
$("#"+page).fadeIn('slow');
});
In CSS Way:-
Use transition to animate. but in this case you only can play smoothly with opacity and visibility and not display
.box{
position: absolute;
opacity: 0;
visibility:hidden;
-webkit-transition: all 2s ease 0s;
-moz-transition: all 2s ease 0s;
-o-transition: all 2s ease 0s;
-ms-transition: all 2s ease 0s;*/
transition: all 2s ease 0s;
}

You can use transitions with opacity rather than hiding an showing the elements.
.box {
position: absolute;
display: block; // not required but do not keep it as display: none
opacity: 0; // make the div invisible!
transition: opacity 1s linear; // tell the browser how and what to transition
-webkit-transition: opacity 1s linear; // webkit support
-moz-transition: opacity 1s linear; // firefox support
}
.box.active {
opacity: 1; // only applies when a box has the class .box and .active
}
Instead of calling .show() to show the element you can add and remove the active class on each div.

Highlight area with backgroundcolor fadein/fadeout

Hi I'd like to highlight .small. Do not have access to add jQuery UI e.g. can't use .animate.
HTML
<span class="small">10 left</span>
jQuery
$(".small").css("background-color","orange");
Question: How do I add background-color orange and make it .fadeOut() here? This below doesn't work? Only want to fadeout the background color, nothing else.
$(".small").css("background-color","orange").fadeOut();

you can use CSS animations to do that
see snippet below
span {
background-color:orange;
animation-name:bckanim;
animation-fill-mode:forwards;
animation-duration:3s;
animation-delay:0s;
}
#keyframes bckanim {
0% {background-color:orange;}
100% { background-color:transparent;}
}
<span class="small">10 left</span>

You can use timeouts and css transitions nicely for this.
For more information about transitions:
https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Transitions/Using_CSS_transitions
$(document).ready(function(){
var $block = $('.block');
/** first timeout to make the document do its stuff before this thing runs **/
window.setTimeout(function() {
$block.addClass('orange-fade');
/** second timeout to turn it back to normal **/
window.setTimeout(function() {
$block.removeClass('orange-fade');
},2000);
},1000);
});
.block {
display:block;
width:200px;
height:200px;
background-color:green;
/** Transitions to give a nice effect **/
-webkit-transition: background-color 1000ms linear;
-moz-transition: background-color 1000ms linear;
-o-transition: background-color 1000ms linear;
-ms-transition: background-color 1000ms linear;
transition: background-color 1000ms linear;
}
.orange-fade {
background-color: #AD310B;
-webkit-transition: background-color 1000ms linear;
-moz-transition: background-color 1000ms linear;
-o-transition: background-color 1000ms linear;
-ms-transition: background-color 1000ms linear;
transition: background-color 1000ms linear;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class=" block transition">
Look at me! Look at you! now look back to me! i'm on a horse!
</div>

You can do something like this with css transitions on a class and then add or remove the class with JS.
HTML:
<span class="small">10 left</span>
CSS:
.small {
background-color: #fff;
transition-property: background-color;
transition-duration: 1s;
transition-delay: 1s;
}
.orange {
background-color: orange;
}
JS:
$(".small").addClass("orange");
DEMO https://jsfiddle.net/ry5qxvos/

try this http://jsfiddle.net/x2jrU/92/ use this jquery to make background color of ur wish with fadein/fadeout option.
jQuery.fn.highlight = function() {
$(this).each(function() {
var el = $(this);
el.before("<div/>")
el.prev()
.width(el.width())
.height(el.height())
.css({
"position": "absolute",
"background-color": "#ffff99",
"opacity": ".9"
})
.fadeOut(500);
});
}
$("#target").highlight();
#target { width: 300px; height: 100px; border: 1px solid red; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="target">Highlight Me</div>

Javascript native implementation div display/hide with animate

I am looking for a native JS solution to toggle div display using display:'none' and display:'block' properties. I have the first part done. I only need the part to do a simple fadeIn and fadeOut animation.
I need to use native JS and display:block,none.
var e = document.getElementById('calendarPickerContainer');
if (e.className == 'visible') {
e.className = 'hidden';
} else {
e.className = 'visible';
}
need to adapt to this css
.visible{
display:block;
}
.hidden {
display:none;
}

If you wanna use a pure JavaScript fadeIn and fadeOut, try this:
transition: opacity 1s linear;
This is a pure CSS method.
#cont {-webkit-transition: opacity 1s linear; -o-transition: opacity 1s linear; transition: opacity 1s linear;}
#cont.hidden {opacity: 0;}
<button onclick="cont.classList.add('hidden'); setTimeout('cont.style.display=\'none\'', 1000);">Click</button>
<div id="cont">
Hello
</div>
Working Snippet (includes toggle):
#cont {-webkit-transition: opacity 1s linear; -o-transition: opacity 1s linear; transition: opacity 1s linear; opacity: 1;}
#cont.hidden {opacity: 0; -webkit-transition: opacity 1s linear; -o-transition: opacity 1s linear; transition: opacity 1s linear;}
<button onclick="if (cont.style.display != 'none') { cont.classList.add('hidden'); setTimeout('cont.style.display=\'none\'', 1000); } else {cont.style.display='block'; setTimeout('cont.classList.remove(\'hidden\')', 10);}">Click</button>
<div id="cont">
Hello
</div>

You can achieve this easily with CSS3
.visible {
visibility: visible;
opacity: 1;
transition: opacity 2s linear;
}
.hidden {
visibility: hidden;
opacity: 0;
transition: visibility 0s 2s, opacity 2s linear;
}

Native JS fade function:
var s = document.getElementById('calendarPickerContainer').style;
s.opacity = 1;
(function fade(){(s.opacity-=.1)<0?s.display="none":setTimeout(fade,40)})();

You can simplfy this with classList
document.querySelector('.toggle').addEventListener('click',function(e) {
e.target.classList.toggle('hide');
})
Css:
div {
transition:all 0.3s ease-in;
}
.hide {
opacity: 0;
}
We're using opacity since display cannot be animated.
Example

ng-animate doesn't let animation be finished

I have set animations on ng-view to fade for 1 second, but it doesn't let the animation out be finished:
.fadethis {
&.ng-enter, &.ng-leave {
-webkit-transition: all linear 1s;
-moz-transition: all linear 1s;
transition: all linear 1s;
display: block !important;
}
&.ng-enter, &.ng-leave.ng-leave-active {
opacity:0;
}
&.ng-leave, &.ng-enter.ng-enter-active {
opacity:1;
}
}
can't I make angular-animate finish the 1 second animation first?
DEMO: http://jsfiddle.net/bnyJ6/79/

It does not look like your view is actually fading out in your example. If it did, the page you are navigating to would appear and begin fading in before the previous page had finished fading out.
Currently I believe the easiest way to simulate the animations waiting for each other is to add a transition-delay to the enter animation (source).
This can get messy though. In your example the page you are navigating to would still begin to take up space before fading in and bump down the page that is fading out. You can get around this by setting your view to position: absolute;.
Demo without transition-delay: http://jsfiddle.net/5evFx/
Demo with transition-delay and position: absolute: http://jsfiddle.net/spKnX/
Working markup:
<div ng-view class="view fadein fadeout"></div>
Working CSS:
.fadein.ng-enter,
.fadeout.ng-leave {
-webkit-transition: all linear 1s;
-moz-transition: all linear 1s;
-o-transition: all linear 1s;
transition: all linear 1s;
display: block !important;
}
.fadein.ng-enter {
opacity: 0;
}
.fadeout.ng-leave {
opacity: 1;
}
.fadein.ng-enter.ng-enter-active {
transition-delay: 1s;
opacity: 1;
}
.fadeout.ng-leave-active {
opacity: 0;
}
html, body, .container {
height: 100%;
}
.view {
position: absolute;
}

Unset element visibility, change innerHTML, and transisition back

I have an element on my HTML page that I want to give dynamic content, and I want inserted HTML to transition from 0% to 100% opacity.
HTML
<div id="content"></div>
CSS
#content {
opacity: 1;
transition: opacity .5s ease-out;
-moz-transition: opacity .5s ease-out;
-webkit-transition: opacity .5s ease-out;
}
#content.hide {
opacity: 0;
}
JavaScript
function setContent(html) {
var content = document.getElementById("content");
//Set hide class
content.className += " hide";
//Set HTML
content.innerHTML = html;
//Unset hide class
content.className = content.className.replace(/(?:^|\s)hide(?!\S)/g, '');
}
Note that setContent() sets and then unsets the hide class. However, it seems that the browser (Chrome at least) does not invalidate content element until after it return from the function, so the element does not get the chance to transistion. How can I make sure that the animation plays?
EDIT: To be clear, setContent() is called after the DOM is loaded. Imagine an app that clears and repopulates the screen when some action occurs.

Can you be more clear as what the context of this is?
Also where are you calling the function? Is the place where you are calling the function inside a DOM ready function?
In jQuery it would be something like this:
$(document).ready(function(){
//call the function inside here.
});

What about using animations?
#content {
padding-left: 32px;
padding-right: 32px;
animation: fadein 0.5s;
-moz-animation: fadein 0.5s;
-webkit-animation: fadein 0.5s;
}
#keyframes fadein {
from {
opacity:0;
}
to {
opacity:1;
}
}
#-moz-keyframes fadein {
from {
opacity:0;
}
to {
opacity:1;
}
}
#-webkit-keyframes fadein {
from {
opacity:0;
}
to {
opacity:1;
}
}
