Opacity transition works on fade out, but not fade in

This is frustrating me to no end. Before I post the code, here's a summary:
The goal, in simple terms: when I double click X, I want it to fade out; when I click Y, I want X to fade in.
The method: I'm using CSS to create the actual fade-in and fade-out "animations." I'm using JavaScript to apply the classes when necessary using a little trickery.
The problem: the fade-in transition doesn't work -- the element just appears instantly. What is driving me insane is the fact that the fade-in, when instantly added back onto a faded-out object, works perfectly. I'll explain this better as a comment in the JS code.
(Yes, I've added opacity: 1 and transition: opacity onto the base elements. It had no effect at all.)
The code:
CSS
*.fade-out {
opacity: 0;
transition: opacity 400ms;
}
*.fade-in {
opacity: 1;
transition: opacity 400ms;
}
*.hide {
display: none;
visibility: hidden;
}
JavaScript
$( '#ArtistEmblem' ).on( 'dblclick', function() {
fadeOut($( '#ArtistEmblem' ));
fadeIn($( '#btnShowLogo' ));
});
$( '#btnShowLogo' ).on( 'click', function() {
fadeOut($( '#btnShowLogo' ));
fadeIn($( '#ArtistEmblem' ));
});
function fadeOut(element) {
element.addClass( 'fade-out' );
setTimeout( function () {
element.addClass( 'hide' );
/*
* I tried immediately adding the 'fade-in' class here
* and it worked -- as soon as the element faded out, it faded
* back in (using the CSS transition). However, outside of this,
* it REFUSES to work; everything appears instantly
*/
console.log('timer triggered');
}, 400);
}
function fadeIn(element) {
element.removeClass( 'hide' );
element.removeClass( 'fade-out' );
element.addClass( 'fade-in' );
}

I apologize if this is something obvious but I've wasted far too much time trying to solve it. I am also open to better, faster, or more efficient solutions if that would be the best answer. Thanks in advance!

The problem is that the initial opacity of "hidden" element is 1 by default. You just need to set it to 0. And also remove display: none –
*.hide {
opacity: 0;
}
Also I would do a little refactoring and remove setTimeout:
$('#ArtistEmblem').on('click', function() {
fade($('#btnShowLogo'), $(this));
});
$('#btnShowLogo').on('click', function() {
fade($('#ArtistEmblem'), $(this));
});
function fade(inElement, outElement) {
inElement.removeClass('hide');
inElement.addClass('fade-in');
outElement.removeClass('fade-in');
outElement.addClass('fade-out');
}
If you don't want the hidden element to occupy space and you want it to be displayed-none, then you need to set display: block before starting the fadeOut.

I know you're asking for a JS heavy answer, but I highly recommend toggling a class of "active", "open" or something similar and using CSS with the transition. Less is more here.
Here's an example fiddle of something I've transitions not only the opacity, but also the z-index. That's the key with these transitions if you intend on having any elements below such as buttons that require hovering, clicking, etc.
JS Fiddle
Key parts:
.container {
z-index: -1;
opacity: 0;
transition: z-index .01s 1s, opacity 1s;
}
.container.active {
transition: z-index 0s, opacity 1s;
z-index: 500;
opacity: 1;
}
EDIT
I was just messing around with this type of thing for my own project, and observing how beautiful Stripe handles their navigation bar. Something so simple changes everything, and that's pointer-events. If you're okay with its support, (notable no ie. 10) this is infinitely easier to integrate. Here's another fiddle of the simulation in a nav bar.
The key part is pointer-events: none, as it ignores click events if set to none, almost as if it wasn't there, yet visibly it is. I highly recommend this.
https://jsfiddle.net/joshmoxey/dd2sts7d/1/

Here is an example using Javascript Animate API. Animate API is not supported in IE/Edge though.
var element = document.getElementById("fade-in-out")
var button = document.getElementById("x")
button.addEventListener("click", function(event) {
element.animate([{opacity: 1, visibility: "visible"},{opacity: 0, visibility: "hidden"}], {duration: 2000})
setTimeout(function() { element.remove() }, 2000)
})
button.addEventListener("dblclick", function(event) {
element && element.animate([{opacity: 0}, {opacity: 1}], {duration: 2000})
})
<input id="x" type="button" value="Click here" />
<div id="fade-in-out"> FADE ME </div>

On hover add / remove class - not always working

I'm implementing some animation by adding and removing classes to an element on mouseover and mouseout. I'm using this method as I found using CSS alone was not reliable; the animation would not complete if the mouse exited the element before the animation finished.
So I have the following code:
<div class="one flip-container">
<div class="flipper">
<div class="front">
<!-- front content -->
</div>
<div class="back">
<!-- back content -->
</div>
</div>
</div>
<script>
jQuery(".flip-container").hover(function () {
jQuery(this).addClass("hover");
},function () {
jQuery(this).delay(2000).queue(function(){
jQuery(this).removeClass("hover");
});
});
</script>
<style>
.flip-container.hover .flipper {
transform: rotateY(180deg);
}
.flipper {
transition: 0.6s;
transform-style: preserve-3d;
position: relative;
}
</style>
This works but sometimes the class 'hover' is not removed, it stays, leaving the element in its animated state. Any idea how to make this more reliable?

Try using mouseenter and then set a timeout function to remove the class that way you wont be adding and removing classes except once each time the mouse enters the area. Also you may want to check to see if the area already has the class to avoid the function from being executed too many times like so:
jQuery(".flip-container").mouseenter(function () {
var el = jQuery(this);
if(!el.hasClass("hover")){
el.addClass("hover");
setTimeout(function(){
el.removeClass("hover");
}, 2000);
}
});

Slidingbar .js animation not smooth

I just built a sliding top panel for a website which is running on wordpress. Therefore I've added the bar into the header by using a hook point. I use a very simple custom.js (mostly copied together from different sources), so that the bar will "slide down" (=appear) on first click and "slide up" (=disappear) on the second click. For some reasons, this animation is not running smoothly. While it is a little bit too fast (which I could easily change by increasing the speed duration), the animations also seems to be laggy. I bet, I oversee something important, cause I am not used to jQuery/Javascript. Exists there some of code snippets to make the transition more smoothly?
Java-Script Markup:
// Slidingbar initialization
var tgslidingbar_state = 0;
// Clicking
jQuery( '.tg-toggle-wrapper' ).click( function(){
var $tgslidingbar = jQuery ( this ).parents( '#tgslidingbar-area').children( '#tgslidingbar' );
//Expand
if ( tgslidingbar_state === 0 ) {
$tgslidingbar.slideDown( 340, 'easeOutQuad' );
jQuery( '.tg-toggle-wrapper' ).addClass( 'open' );
tgslidingbar_state = 1;
//Collapse
} else if( tgslidingbar_state == 1 ) {
$tgslidingbar.slideUp(340,'easeOutQuad');
jQuery( '.tg-toggle-wrapper' ).removeClass( 'open' );
tgslidingbar_state = 0;
}
});
HTML-Markup:
<div id="tgslidingbar-area" class="tgslidingbar-area">
<div style="display: none;" id="tgslidingbar">
<div class="containertop">
Slidingbar Content Here!
</div></div>
<div class="tg-toggle-wrapper"><a class="tg-toggle" href="#"></a>
</div></div>
With this markup the sliding bar does slide down and up. For example, I've added a google maps into the sliding bar, when I've noticed that the bar is laggy. Could this be a reason for the laggy animations, too, cause google maps just loads when the bar opens? I also realized the "easeOutQuad" property in the copied snippet animations and searched for this on the web. It seems to be a popular jQuery library for animations. Up to now I do not have included this library into my websites, maybe thats the cause?
Kind Regards from Germany!

I applied some modification on the code.
I use query’s animate function.
A initial display property of #tgslidingbar was changed to ‘block’
added ‘padding’ on container top class and removed ‘padding’ on tgslidingbar class.
https://jsfiddle.net/nigayo/cn49ubr6/
[html]
<div style="display:block;height:0" id="tgslidingbar">
[JS]
var tgslidingbar_state = 0;
var $tgslidingbar = jQuery('#tgslidingbar');
var nHeight = $tgslidingbar.get(0).scrollHeight;
// Handle the slidingbar toggle click
jQuery('.tg-toggle-wrapper').click(function() {
//Expand
if (tgslidingbar_state === 0) {
$tgslidingbar.animate({
'height': nHeight
}, 340, function() {
jQuery('.tg-toggle-wrapper').addClass('open');
tgslidingbar_state = 1;
});
......

I suggest some different options.
first,
Instead, use jquery's animate function.
http://api.jquery.com/animate/
sample code : https://jsfiddle.net/nigayo/jo5vd2ob/
second.
you can use css transition.
http://jsfiddle.net/nigayo/qy1ummx6/1/
[css]
.box {
float: left;
/* you can use other ease effect. ease-in, ease-out, ease-in-out */
-webkit-transition: all 1s ease;
overflow: hidden;
}
.height {
background-color: red;
width: 300px;
max-height: 0px;
}
.change {
max-height: 500px;
}
[JS]
$('button').on('click', function() {
$('.box').toggleClass('change');
});

Webflow and Fullpage.js interfering with each other

I am currently using the fullpage.js plugin on a test website I designed with webflow. Everything worked correctly until I included the plugin. Now, the scrolling interactions of webflow don't work anymore.
I think the two javascript files kind of interfere with each other, limiting functions of the other one to work correctly. I would love to fix this but I really don't know how.
This is the site without the fullpage.js included. This is the site with the fullpage.js included. As you can see, in the first example the paragraphs fade in and out on scrolling. In the second example they don't. The paragraphs simply stay in their initial appearance state which is opacity = 0. I really would love to see the fullpage.js working side by side with the webflow interactions.

You'll find the answer in fullPage.js FAQs:
jQuery scroll event doesn't work
Same answer as Parallax doesn't work with fullpage.js
Also, consider using the callbacks provided by fullpage.js such as afterLoad, onLeave, afterSlideLeave and onSlideLeave detailed in the docs or the class added to the body element containing the active section/slide.
And:
Parallax doesn't work with fullpage.js.
Short answer: use the scrollBar:true option for fullPage.js or autoScrolling:false if you don't want to use the auto-scrolling feature.
Explanation: Parallax, as well as many other plugins which depends on the scrolling of the site, listens the scrollTop property of javascript. fullPage.js doesn't actually scroll the site but it changes the top or translate3d property of the site. Only when using the fullPage.js option scrollBar:true or autoScrolling:false it will actually scroll the site in a way it is accessible for the scrollTop property.
If you just want your text to fadeIn or out, I would use the CSS class added to the body on page change. But feel free to use the callbacks as well combined with javascript or jQuery to create your effects.

I solved how to run SCROLL animations in WEBFLOWE if you use FULLPAGE.JS. To scroll ANCHOR, after refreshing for each ANCHOR, refresh the scrolla position as follows:
$(document).ready(function() {
$('#fullpage').fullpage({
anchors: ['01', '02', '03', '04', '05'],
animateAnchor: true,
easing: 'easeInOutCubic',
scrollingSpeed: 600,
scrollOverflow: true,
scrollOverflowReset: true,
//
afterLoad: function(origin, destination, direction){
var loadedSection = this;
//refresh scroll position
$.fn.fullpage.setAutoScrolling(false);
$.fn.fullpage.setAutoScrolling(true);
//
if(origin.anchor == '01'){
}
if(origin.anchor == '02'){
}
if(origin.anchor == '03'){
}
if(origin.anchor == '04'){
}
if(origin.anchor == '05'){
}
}
});
});

Trying to fade and slide text out of initials on mouse over with jQuery

I'm trying to create an effect with jQuery where on mouse over of my initials on the page in the header, the div they are in expands (using jQuery animate) and the text of my full name fades in from each initial.
I have tried a variety of things but am not sure what is the best way to do this. I'm a bit stuck. I'm currently trying to get it going by having the initials of my name "OW" in two separate divs and then the remainder of my name to make up "wen" and "illiams" in between those initals. Like so:
<div class="initialF inlinediv">O</div>
<div class="fullF inlinediv">wen</div>
<div class="initialL inlinediv">W</div>
<div class="fullL inlinediv">illiams</div>
I thought it would work to use jQuery slideLeft and .fadeIn to get the text to slide in from the left as well as fading to look like the text is emerging from the initials but the animations was jumpy and would go onto a second line while the div was still expanding. I am using the below jQuery to detect the mouseIn/Out events:
<script>
$(".brand").mouseenter(function() {
$('.brand').animate({width: '160px'});
$('.fullF').fadeIn("slow");
});
$(".brand").mouseout(function() {
$('.brand').animate({width: '36px'});
$('.fullF').fadeOut("slow");
});
</script>
The alternatives I have tried were using jquery.lettering.js to help with it but there seemed to be some issues with that. Any suggestions to push me in the right direction would be useful and my site with a partially working example is here:
http://192.241.203.146/

Here's one using css transitions rather than jquery animate: http://jsfiddle.net/S58Se/2/
<div class='branding'>
<span class='initial'>O</span><span class='hidden nameFull wen'>wen</span>
<span class='initial'>W</span><span class='hidden nameFull illiams'>illiams</span>
</div>
span {
display: inline-block;
overflow: hidden;
transition: all 1s;
-moz-transition: all 1s;
-webkit-transition: all 1s;
}
.wen { width: 36px; }
.illiams { width: 160px; }
span.hidden {
width: 0px;
opacity: 0;
}
$('.branding').hover(
function() { $('.nameFull').removeClass('hidden'); },
function() { $('.nameFull').addClass('hidden'); }
);
Or you can do away with the javascript altogether with this: http://jsfiddle.net/S58Se/3/
remove the js and add these css statements:
.branding:hover .wen {
width: 36px;
opacity: 1;
}
.branding:hover .illiams {
width: 160px;
opacity: 1;
}
... just because I think it's neat.

A good way to go about this is to just expand the use of your call to the animation method by adding another property to the object you are passing in. So instead of calling an extra method (fadeIn) you just handle it all in one fell swoop:
$('.brand').on({
'mouseenter' : function () {
$('.nameFull').stop().animate({
'width' : '200px',
'opacity' : '1'
}, 500);
},
'mouseleave' : function () {
$('.nameFull').stop().animate({
'width' : '0',
'opacity' : '0'
}, 500);
}
});
You'll notice I'm also using 'on' instead of the 'hover' or 'mouseenter' and 'mouseleave' methods. In most recent versions of jQuery those methods just reference 'on', so it's better to just cut out the middle man and do it all in one place.
I'm not sure if this exactly fits your design, but I made a Codepen to demonstrate the code in action: http://codepen.io/Tristan-zimmerman/pen/lnDGh

Style the hidden divs position:absolute, and when show them:
'show' them first, to set them visible
then position them (next to your 'launching' div), using jQuery.position();
set the animation going.
Essentially you want them 'absolute' to avoid them thunking in/out & changing your existing flow. position() must be called after making the element visible, and then you should have appropriate starting conditions to kick off your animation.
Or you could try using <span>' for the incoming text and/or displaying as inline-block, which may help avoid the "incoming" kicking things down a line. HTH.

I think what you are looking for is something like this: JSFiddle
html:
<div class="brand">
<div>O<span class="full">wen </span>W<span class="full">illiams</span></div>
</div>
jq:
$('.brand').hover(function(){
$(this).stop().animate({width: '160px'},'slow',function(){
$(this).children('div').children('.full').stop().fadeIn('slow');
});
},function(){
$(this).children('div').children('.full').stop().fadeOut('slow',function(){
$(this).parent().parent().stop().animate({width: '36px'},'slow');
});
});
css:
.full{
display: none;
}
note: there is a simple bug that happens in a specific case and I'm working on it.
