I've been trying to create a fadein/fadeout effect for my pages in my Ruby on Rails app. I found a website, https://coderwall.com/p/t5ghhw/animated-page-transitions-in-rails-4-apps, that seemed to offer a reasonable guide, but it isn't working.
In each of my html files (except for application.html.erb), I have a div that encloses all of the content with a class called "primary-content." Then I have a css file, animate.css(adapted from http://daneden.github.io/animate.css/), with the following code:
.animated {
-webkit-animation-duration: 5s;
animation-duration: 5s;
-webkit-animation-fill-mode: both;
animation-fill-mode: both;
}
.animated.infinite {
-webkit-animation-iteration-count: infinite;
animation-iteration-count: infinite;
}
#-webkit-keyframes fadeInUp {
0% {
opacity: 0;
-webkit-transform: translate3d(0, 100%, 0);
transform: translate3d(0, 100%, 0);
}
100% {
opacity: 1;
-webkit-transform: none;
transform: none;
}
}
#keyframes fadeInUp {
0% {
opacity: 0;
-webkit-transform: translate3d(0, 100%, 0);
transform: translate3d(0, 100%, 0);
}
100% {
opacity: 1;
-webkit-transform: none;
transform: none;
}
}
.fadeInUp {
-webkit-animation-name: fadeInUp;
animation-name: fadeInUp;
}
#-webkit-keyframes fadeOutUp {
0% {
opacity: 1;
}
100% {
opacity: 0;
-webkit-transform: translate3d(0, -100%, 0);
transform: translate3d(0, -100%, 0);
}
}
#keyframes fadeOutUp {
0% {
opacity: 1;
}
100% {
opacity: 0;
-webkit-transform: translate3d(0, -100%, 0);
transform: translate3d(0, -100%, 0);
}
}
.fadeOutUp {
-webkit-animation-name: fadeOutUp;
animation-name: fadeOutUp;
}
This css file is in my assets/css folder, and is called in the header of my application.html.erb file.
Then there's the javascript, in a file in the assets/javascripts folder. It's required in application.js and called in the header of application.html.erb--and, when it wasn't working, I also called it at the bottom of each view. The code reads:
document.addEventListener('page:change', function() {
document.getElementById('primary-content').className += 'animated fadeInUp';
});
document.addEventListener('page:fetch', function() {
document.getElementById('primary-content').className += 'animated fadeOutUp';
});
I'm aiming for the existing page to fade out upward, and the new page to fade in upward. Does anyone see what I'm missing? I don't have any experience with keyframes, or with using -webkit in css, but that's all borrowed from the animate.css site.
Thanks!

Stopping a CSS3 Animation on last frame
(8 answers)
Closed 6 years ago.
I simply want the #upmenu to stay up outside the viewport once the animation is ended.
I'm struggling to understand what I am doing wrong.
Thanks for your help.
$(document.body).ready(function() {
$("#num").hover(function() {
$("#upmenu").toggleClass("toptop"), $("#fp-nav").toggleClass("top")
})
})
#upmenu{
position:fixed;
top:0;
}
.toptop {
-webkit-animation: slide-out-top 1.5s cubic-bezier(.215, .61, .355, 1);
animation: slide-out-top 1.5s cubic-bezier(.215, .61, .355, 1)
}
#-webkit-keyframes slide-out-top {
0% {
-webkit-transform: translateY(0);
transform: translateY(0)
}
to {
-webkit-transform: translateY(-100%);
transform: translateY(-100%)
}
}
#keyframes slide-out-top {
0% {
-webkit-transform: translateY(0);
transform: translateY(0)
}
to {
-webkit-transform: translateY(-100%);

You can achieve this by setting the animation-fill-mode to forwards. In the case of your code where you use the animation shorthand rule, it's the last property in the list on each line:
$(document.body).ready(function() {
$("#num").hover(function() {
$("#upmenu").toggleClass("toptop"), $("#fp-nav").toggleClass("top")
})
})
#upmenu {
position: fixed;
top: 0;
}
.toptop {
-webkit-animation: slide-out-top 1.5s cubic-bezier(.215, .61, .355, 1) forwards;
animation: slide-out-top 1.5s cubic-bezier(.215, .61, .355, 1) forwards;
}
#-webkit-keyframes slide-out-top {
0% {
-webkit-transform: translateY(0);
transform: translateY(0)
}
to {
-webkit-transform: translateY(-100%);
transform: translateY(-100%)
}
}
#keyframes slide-out-top {
0% {
-webkit-transform: translateY(0);
transform: translateY(0)
}
to {
-webkit-transform: translateY(-100%);
transform: translateY(-100%)
}
}

I have a few pages on my website and i made a header animation (pulldown). So, i need to reverse my animation (pullUp) when the other one page is clicked. Is there any option to do that ? Or is there any option to make the second animation (pullup) active when the other page is selleced
header{
background-color:black;
height:80px;
text-align:center;
animation-name: pullDown;
-webkit-animation-name: pullDown;
animation-duration: 2s;
-webkit-animation-duration: 2s;
animation-timing-function: ease-out;
-webkit-animation-timing-function: ease-out;
transform-origin: 50% 0%;
-ms-transform-origin: 50% 0%;
-webkit-transform-origin: 50% 0%;
}
.pullUp{
animation-name: pullUp;
-webkit-animation-name: pullUp;
animation-duration: 1.1s;
-webkit-animation-duration: 1.1s;
animation-timing-function: ease-out;
-webkit-animation-timing-function: ease-out;
transform-origin: 50% 100%;
-ms-transform-origin: 50% 100%;
-webkit-transform-origin: 50% 100%;
}
#keyframes pullUp {
0% {
transform: scaleY(0.1);
}
40% {
transform: scaleY(1.02);
}

transform: scaleY(0.98);
}

transform: scaleY(1.01);
}
100% {
transform: scaleY(0.98);
}
80% {
transform: scaleY(1.01);
}
100% {
transform: scaleY(1);
}
}
#-webkit-keyframes pullUp {
0% {
-webkit-transform: scaleY(0.1);
}
40% {
-webkit-transform: scaleY(1.02);
}
60% {
-webkit-transform: scaleY(0.98);
}
80% {
-webkit-transform: scaleY(1.01);
}
100% {
-webkit-transform: scaleY(0.98);
}
80% {
-webkit-transform: scaleY(1.01);
}
100% {
-webkit-transform: scaleY(1);
}
}
There are a few options I can recommend:
Use CSS's :active selector to bind to the hash of the "pulldown" item:
```
second-page:active ~ .drawer {
animation: "pullUp" 1s linear;
}
```
So that when the user clicks on the url to your second page (#second-page), the animation will trigger, thus hiding the drawer itself.
Use Javascript to toggle classes:
(jQuery)
var $drawer = $(".drawer");
var $drawerToggle = $(".drawer-toggle").on("click", function() {
$drawer.toggle("fast");
}
Use an input[type="checkbox"] 'hack':
.drawer-toggle:checked ~ .drawer {
animation: "pullDown" 1s linear;
}
.drawer-toggle ~ .drawer {
animation: "pullUp" 1s linear;
}
Here is my code http://codepen.io/anon/pen/zrXrXM but as i told, when i click on <a> element, page transition is instantly. Is there any possible way to stop transition for a few seccond ?
I print success message using PHP like this :
<div class='alert alert-success'>Success!!</div>
I have this CSS3 Animate:
.animated {
-webkit-animation-duration: 1s;
animation-duration: 1s;
-webkit-animation-fill-mode: both;
animation-fill-mode: both;
}
.animated.infinite {
-webkit-animation-iteration-count: infinite;
animation-iteration-count: infinite;
}
.animated.hinge {
-webkit-animation-duration: 2s;
animation-duration: 2s;
}
#-webkit-keyframes fadeOutUp {
0% {
opacity: 1;
}
100% {
opacity: 0;
-webkit-transform: translate3d(0, -100%, 0);
transform: translate3d(0, -100%, 0);
}
}
#keyframes fadeOutUp {
0% {
opacity: 1;
}
100% {
opacity: 0;
-webkit-transform: translate3d(0, -100%, 0);
transform: translate3d(0, -100%, 0);
}
}
.fadeOutUp {
-webkit-animation-name: fadeOutUp;
animation-name: fadeOutUp;
}
Now, I need to remove success message with my CSS Animate (fadeOutUp) after 5 seconds using jQuery. How do can i create this?!
You can create a hide a class which hide your element setting the opacity to 0 with a transition and add this class to your div with JavaScript.
CSS
.hide {
opacity: 0;
transition: opacity 1000ms;
}
JS
function fadeOut(el){
el.classList.add('hide');
}
div = document.getElementById('yourDiv');
setTimeout(function(){
fadeOut(div);
}, 5000);
HTML
<div id='yourDiv' class='alert alert-success'>Success!!</div>
Checkout this codepen.
Is this what you are looking for?
setTimeout(animateUp, 5000);
function animateUp() {
$(".alert").css({'-webkit-animation' : 'fadeOutUp 5s infinite'});
}
or update your .fadeOutUp CSS to
.fadeOutUp {
-webkit-animation: fadeOutUp 5s infinite;
animation: fadeOutUp 5s infinite;
}
Then you can do
setTimeout(animateUp, 5000);
function animateUp() {
$(".alert").addClass("fadeOutUp");
}
JSFiddle
Essentially what I'm trying to do is give an element a CSS animation when it gains a class, then reverse that animation when I remove the class without playing the animation when the DOM renders.
Fiddle here: http://jsfiddle.net/bmh5g/
As you can see in the fiddle, when you hover the "Hover Me" button, #item flips down. When you mouseoff the hover button, #item just disappears. I want #item to flip back up (ideally using the same animation but in reverse). Is this possible?
$('#trigger').on({
mouseenter: function() {
$('#item').addClass('flipped');
},
mouseleave: function() {
$('#item').removeClass('flipped');
}
})
#item {
position: relative;

I would have the #item start out hidden with the reverse animation by default. Then add the class to give it the animation and show the #item. http://jsfiddle.net/bmh5g/12/

$('#item').show();
$('#item').addClass('flipped');
},
mouseleave: function() {

Another approach, rather than using display: none, is to suppress the reverse animation with a class on page load, and then remove that class with the same event that applies the normal animation (eg: flipper). Like so (http://jsfiddle.net/astrotim/d7omcbrz/1/):
CSS - in addition to the flipperUp keyframe posted by Blake above
#item.no-animation
{
animation: none;
}
jQuery
$('#trigger').on({
mouseenter: function(){
$('#item').removeClass('no-animation');
$('#item').addClass('flipped');
},
mouseleave: function(){
$('#item').removeClass('flipped');
}
})
In addition to the answers here, please cache your $(selector)
So you pretty much do this var elements = $(selector); to cache.
Why?! Because if you use the code in the answers on this page as is you will ask the DOM for that same element collection ($('#item')) each time. DOM reading is an expensive operation.
For example, the accepted answer would look something like so:
var item = $('#item');
$('#trigger').on({
mouseenter: function(){
item.show();
item.addClass('flipped');
},
mouseleave: function(){
item.removeClass('flipped');
}
});
Since I've written all this text, might as well answer your question using CSS transitions
I know you asked for a CSS animations example, but for the animation you wanted to do (a card flipping open), it can be easily achieved using CSS transitions:
#item {
width: 70px;
height: 70px;
background-color: black;
line-height: 1;
color: white;
}
#item+div {
width: 70px;
height: 100px;
background-color: blue;
transform: perspective(250px) rotateX(-90deg);
transform-origin: 50% 0%;
transition: transform .25s ease-in-out
}
#item:hover+div {
transform: perspective(250px) rotateX(0);
}
<div id="item"></div>
<div></div>
Its animating down using css so to get it to animate up you need to create a class, say .item-up that does the transformation in the opposite so then you would remove the previous class and add the item-up class and that should animate it up.
I would write you a js fiddle for it but I dont know the syntax well enough.
Basically when you will need:
#keyframes flipper
#keyframes flipper-up //This does the opposite of flipper
and
$('#trigger').on({
mouseenter: function(){
$('#item').removeClass('flipped-up');
$('#item').addClass('flipped');
},
mouseleave: function(){
$('#item').removeClass('flipped');
$('#item').addClass('flipped-up');
}
})

You can make use of the attribute animation-direction to run the same animation in reverse.
If you couple this with one of the many methods described here for restarting an animation- we can start the animation forwards on mouseenter, then on mouseleave we can restart it and play it in reverse.
I don't know how to use jQuery very well, so I chose one of the non-jQuery methods mentioned in the article.
const element_button = document.getElementById('trigger');
const element_item = document.getElementById('item');
element_button.addEventListener("mouseenter", () => {
if (element_item.classList.contains('animate-backwards')) {
element_item.classList.remove('animate-backwards');
void element_item.offsetWidth;
}
element_item.classList.add('animate-forwards');
});
element_button.addEventListener("mouseleave", () => {
element_item.classList.remove('animate-forwards');
void element_item.offsetWidth;
element_item.classList.add('animate-backwards');
});
and
#item.animate-forwards {
animation: flipper 0.7s normal;
-webkit-animation: flipper 0.7s normal;
animation-fill-mode: forwards;
-webkit-animation-fill-mode: forwards;
}
#item.animate-backwards {
animation: flipper 0.7s reverse;
-webkit-animation: flipper 0.7s reverse;
animation-fill-mode: forwards;
-webkit-animation-fill-mode: forwards;
}
Here is a jsFiddle for the above code.
Worked fo me:
1 animation in reverse for the Element (from 100% to 0%)
1 separate animation forwards for the new class (from 0% to 100%)
And toggling that class would work
[1]: https://jsfiddle.net/q7bc4s0f/17/
Upd:
That way animation will play backwards on page load. To solve this you have to ADD new bacwards animation class on event ONCE and then toggle forwards animation class on that event.
I need to override the default slide effect to dissolve effect.
When changePage function is called I need to slowly dissolve the current page to new page.
I tried with following CSS
#keyframes dissolve {
0% { opacity:1; }
5% { opacity:0.9;}
15% { opacity:0.7;}
25% { opacity:0.5;}
35% { opacity:0.3;}
45% { opacity:0;}
55% { opacity:0.2;}
65% { opacity:0.4;}
75% { opacity:0.6;}
85% { opacity:0.8;}
95% { opacity:0.9;}
100% { opacity:1;}
}
.in, .out, .slide.in, .slide.out, .slide.out.reverse, .slide.in.reverse {
-webkit-animation-name: dissolve;
-moz-animation-name: dissolve;
-webkit-animation-timing-function: ease-in-out;
-webkit-animation-duration: 350ms;
-moz-animation-timing-function: ease-in-out;
-moz-animation-duration: 350ms
}
I have created a fiddle with above css.

100% { opacity: 0; }
}
#keyframes dissolve-in {

20% { opacity: 0; }
40% { opacity: 0; }
60% { opacity: 0.2; }
80% { opacity: 0.6; }
100% { opacity: 1; }
}
.slideup.in, .slide.in, .slide.in.reverse {
-webkit-animation: dissolve-in;
-moz-animation: dissolve-in;
-webkit-animation-timing-function: ease-in-out;
-moz-animation-timing-function: ease-in-out;
-webkit-animation-duration: 3s !important;
-moz-animation-duration:3s !important;
}
.slide.out, .slide.out.reverse {
-webkit-transform: translateX(0%);
-webkit-animation: dissolve-out;
-moz-transform: translateX(0%);
-moz-animation: dissolve-out;
-webkit-animation-timing-function: ease-in-out;
-moz-animation-timing-function: ease-in-out;
-webkit-animation-duration: 3s !important;
-moz-animation-duration:3s !important;
}
Please see the demo.
Above CSS will give you a dissolve effect with overriding the default slide effect of page transistion in jQuery Mobile.
