How to change Bootstrap tabs fade OUT speed? - javascript

I am trying to change the speed of a fade effect in Bootstrap. I found this answer using css:
#import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css');
.fade {
opacity: 0;
-webkit-transition: opacity 1.5s linear;
-moz-transition: opacity 1.5s linear;
-ms-transition: opacity 1.5s linear;
-o-transition: opacity 1.5s linear;
transition: opacity 1.5s linear;
}
<div class="btn-group" role="group">
<button class="btn active" data-toggle="tab" href="#one">One</button>
<button class="btn" data-toggle="tab" href="#two">Two</button>
<button class="btn" data-toggle="tab" href="#three">Three</button>
</div>
<div class="tab-content">
<div id="one" class="tab-pane fade in active">This is the One</div>
<div id="two" class="tab-pane fade">This is the Two</div>
<div id="three" class="tab-pane fade">This is the Three</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
...but this only affects the fade-in time. The fade-out stays the same. Any suggestions?

There is no fade-out time, the class that makes the element visible just gets removed.
To make it fade-out, you have to make sure the item doesn't get removed from the dom (HTML document), but rather make it invisible so it can fade.
Here is an example, adjust to your wishes:
#import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css');
.tab-content {
position:relative;
}
.tab-content>.tab-pane {
/* in order to make sure the elements are nicely in position
use position:absolute; */
position:absolute;
top:0;
}
.fade {
opacity: 0;
-webkit-transition: opacity 1.5s linear;
-moz-transition: opacity 1.5s linear;
-ms-transition: opacity 1.5s linear;
-o-transition: opacity 1.5s linear;
transition: opacity 1.5s linear;
}
.tab-content>.tab-pane:not(.in) {
/* display:none; is the default behaviour, make that display:block; */
display:block;
/* make the opacity 0, that is what the transition responds to! */
opacity:0;
}
<div class="btn-group" role="group">
<button class="btn active" data-toggle="tab" href="#one">One</button>
<button class="btn" data-toggle="tab" href="#two">Two</button>
<button class="btn" data-toggle="tab" href="#three">Three</button>
</div>
<div class="tab-content">
<div id="one" class="tab-pane fade in active">This is the One</div>
<div id="two" class="tab-pane fade">This is the Two</div>
<div id="three" class="tab-pane fade">This is the Three</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

The issue is that when an item is not active, it's display property is set to display:none, and therefore is being hidden before any animation can be applied. If you position everything using absolute position to overlap, then you can leave the display as display:block and just change the opacity:
#import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css');
.fade {
opacity: 0;
-webkit-transition: opacity 1.5s linear;
-moz-transition: opacity 1.5s linear;
-ms-transition: opacity 1.5s linear;
-o-transition: opacity 1.5s linear;
transition: opacity 1.5s linear;
}
.tab-content {
position:relative;
}
.tab-content>.tab-pane {
top: 0;
position:absolute;
display:block;
}
.tab-content>.tab-pane:not(.active) {
opacity: 0;
}
<div class="btn-group" role="group">
<button class="btn active" data-toggle="tab" href="#one">One</button>
<button class="btn" data-toggle="tab" href="#two">Two</button>
<button class="btn" data-toggle="tab" href="#three">Three</button>
</div>
<div class="tab-content">
<div id="one" class="tab-pane fade in active">This is the One</div>
<div id="two" class="tab-pane fade">This is the Two</div>
<div id="three" class="tab-pane fade">This is the Three</div>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

If you simply want to avoid having the fade affect, or need the tabs to appear more quickly remove the fade class.
// Original
<div class="tab-content">
<div id="one" class="tab-pane fade in active">This is the One</div>
<div id="two" class="tab-pane fade">This is the Two</div>
<div id="three" class="tab-pane fade">This is the Three</div>
</div>
// Updated
<div class="tab-content">
<div id="one" class="tab-pane in active">This is the One</div>
<div id="two" class="tab-pane fade">This is the Two</div>
<div id="three" class="tab-pane fade">This is the Three</div>
</div>
The fade class is only applied to the first pane, then when the button is clicked then Jquery removes the active class and fade class and applies it to the corresponding pane.

Transition doesn’t work when switching between classes

When I switch between classes at first time, opacity transition doesn’t work.
When I switch back, it does work. I tried removing visibility property and leaving just opacity, did not work.
const navList = document.querySelector('.nav-list')
if (navList.classList.contains('invisible')) {
setTimeout(function() {
navList.classList.add('visible'), navList.classList.remove('invisible');
}, 1000);
} else {
setTimeout(function() {
navList.classList.add('invisible');
});
navList.classList.remove('visible');
}
.visibile {
opacity: 1;
visibility: visible;
transition: all ease-in 1s;
}
.invisible {
opacity: 0;
visibility: hidden;
transition: all ease-in 1s;
}
<ul class="nav-list invisible text-center mt-5">
<div class="">
<div class="">
<div>
<li class="p-3 underline">Home</li>
<li class="p-3 underline">About</li>
<li class="p-3 underline">Contact</li>
</div>
</div>
</div>
</ul>
As mentioned in the comments, put the transition on a class that's always present, eg nav-list. I would also recommend putting some state on that class so then you only need to toggle one other class (instead of two).
const navList = document.querySelector('.nav-list')
setInterval(() => {
navList.classList.toggle('invisible')
}, 2000)
.nav-list {
transition: all ease-in 1s;
opacity: 1;
visibility: visible;
}
.nav-list.invisible {
opacity: 0;
visibility: hidden;
}
<ul class="nav-list invisible text-center mt-5">
<div class="">
<div class="">
<div>
<li class="p-3 underline">Home</li>
<li class="p-3 underline">About</li>
<li class="p-3 underline">Contact</li>
</div>
</div>
</div>
</ul>

JQuery FadeIn & CSS slide in is choppy

JSFiddle
I'm not happy with the current result of the code in the fiddle, I'd like it to be less choppy and just fade in while also sliding in from the bottom but my JQuery skills are not the greatest. Is using CSS as the slide in the best choice? Wasn't able to find any examples of sliding in using JQuery.
Any help much appreciated.
Here's the same code.
<!doctype html>
<html lang="en">
<style>
#keyframes slideInFromBottom {
0% {
transform: translateY(100%);
}
100% {
transform: translateY(0);
}
}
.v1 {
animation: 1s ease-out 0s 1 slideInFromBottom;
}
.v2 {
animation: 1s ease-out 0.2s 1 slideInFromBottom;
}
.v3 {
animation: 1s ease-out 0.4s 1 slideInFromBottom;
}
</style>

$("#preload_v2").fadeIn(2000);
});
$("#v3").ready(function(){
$("#preload_v3").fadeIn(2000);
});
</script>
</html>
I removed the jQuery scripts and made it work with css alone.
replaced style="display:none" on img tag with following css
.card{
opacity:0;
}
For fadeIn effect changed opacity from 0 to 1
#keyframes slideInFromBottom {
0% {
transform: translateY(100%);
opacity: 0;
}
100% {
transform: translateY(0);
opacity: 1;
}
}
To keep the animation in final state added forwards to animation and also updated animation-duration and animation-delay
.v1 {
animation: 1s ease-out 0s 1 slideInFromBottom forwards;
}
.v2 {
animation: 1.2s ease-out 0.2s 1 slideInFromBottom forwards;
}
.v3 {
animation: 1.4s ease-in 0.4s 1 slideInFromBottom forwards;
}

This is the css:
.scrollup :hover should be .scrollup:hover
You are setting the opacity to 1 but the opacity is already 1.
maybe you can set the opacity of 0.5 for the normal state, then at hover 1.
try this:
.scrollup {
height:50px;
width:50px;
right:50px;
bottom:50px;
position:fixed;
opacity: 0.5;
filter: alpha(opacity=50);
-webkit-transition: all .3s ease;
-o-transition: all .4s ease;
transition: all .4s ease;
background: url('http://s29.postimg.org/59qiyrlab/freeiconmaker_1.png?noCache=1447752779');
background-repeat:no-repeat;
background-size:contain
}
.scrollup:hover {
opacity: 1.0;
filter: alpha(opacity=100);
}
I have added an additional
-webkit-transition: all .3s ease;
-o-transition: all .4s ease;
transition: all .4s ease;
to smooth things a little.

Change Slit Slider Revised effect to fadein fadeout

I am coding a website which needs the full-screen fadein fadeout slider with content and next previous navigation . So I found this.
But the main problem is that I need this effect to fadein fadeout.
You can use bootstrap-carousel

Fading between images in a carousel

I've been trying to understand why my carousel won't fade between transitions. It cycles as expected, but don't seem to apply the transition effect to make one panel fade in to the next.
Here's what I have so far:
/* Javascript */
function cycle() {
var active = $('.carousel .item.active');
var panels = $('.carousel .item');
var pos = panels.index(active);
var next = panels.eq((pos >= 5) ? 0 : ++pos);
next.addClass('active');
active.removeClass('active');
}
var interval = setInterval(cycle, 2000);
/* CSS */
.carousel-inner {
position: relative;
width: 100%;
overflow: hidden;
}
.carousel .item {
-webkit-transition: opacity 0.6s ease-in-out;
-moz-transition: opacity 0.6s ease-in-out;
-o-transition: opacity 0.6s ease-in-out;
transition: opacity 0.6s ease-in-out;
opacity: 0;
}
.carousel .item.active {
opacity: 1;
}
/* HTML */
<div id="id_landing_carousel" class="carousel slide">
<div class="carousel-inner">
<div class="item" data-nav-button="nav-home">
<img src="/media/carousel/home.png">
<div class="carousel-caption">
<h4><p>Welcome</p></h4>
</div>
</div>
<div class="item" data-nav-button="nav-residential">
<img src="/media/carousel/residential.jpg">
<div class="carousel-caption">
<h4><p>Residential</p></h4>
</div>
</div>
<div class="item" data-nav-button="nav-commercial">
<img src="/media/carousel/commercial.jpg">
<div class="carousel-caption">
<h4><p>Commercial</p></h4>
</div>
</div>
<div class="item" data-nav-button="nav-service">
<img src="/media/carousel/service.jpg">
<div class="carousel-caption">
<h4><p>Service</p></h4>
</div>
</div>
<div class="item active" data-nav-button="nav-blog">
<img src="/media/carousel/blog.jpg">
<div class="carousel-caption">
<h4><p>Blog</p></h4>
</div>
</div>
<div class="item" data-nav-button="nav-contact">
<img src="/media/carousel/contact.jpg">
<div class="carousel-caption">
<h4><p>Contact us</p></h4>
</div>
</div>
</div>
</div>
If anyone has any insight in to what I"m doing wrong, I'd very much appreciate it.
Damn. Nevermind. Solved it myself. Another style was setting the carousel's div element to display: none when it wasn't active.
