I have this code
$('#uiAdminPanelMenu li a').hover( function(){
$(this).css('background-color', '#D3E1FA';
},
function(){
$(this).css('background-color', '#F4F4F4');
});
it changes the background color of the link, but I want it to change it slowly, kinda like fade effect, but for this case.
You can accomplish the same thing with CSS3 transitions. The result will almost be the exact same.
#uiAdminPanelMenu li a {
background-color: F4F4F4;
-webkit-transition: background-color 0.4s ease;
-moz-transition: background-color 0.4s ease;
-o-transition: background-color 0.4s ease;
transition: background-color 0.4s ease;
}
#uiAdminPanelMenu li a:hover {
background-color: D3E1FA;
}
You want to use animate(), but you also need the Color Plugin for jQuery.
With the color plugin included, the following code works well:
$('#uiAdminPanelMenu li a').hover( function(){
$(this).animate({'background-color': '#D3E1FA'}, 'slow');
},
function(){
$(this).animate({'background-color': '#F4F4F4'}, 'slow');
});
May be its very late for answering this question, but still wanted to provide an alternate solution that worked for me. (Both the answers provided earlier will work).
I used CSS Animation and that worked better for me than jquery animate in few other cases as well.
You can try the below -
// 'bcolor' is animation keyframe name defined later
#uiAdminPanelMenu li a:hover {
-webkit-animation-name: bcolor;
-webkit-animation-duration: 1s;
-webkit-animation-fill-mode: forwards;
-moz-animation-name: bcolor;
-moz-animation-duration: 1s;
-moz-animation-fill-mode: forwards;
animation-name: bcolor;
animation-duration: 1s;
animation-fill-mode: forwards;
}
#-webkit-keyframes shadeOn {
from {background-color: #F4F4F4;}
to {background-color: #D3E1FA;}
}
#-moz-keyframes shadeOn {
from {background-color: #F4F4F4;}
to {background-color: #D3E1FA;}
}
#keyframes shadeOn {
from {background-color: #F4F4F4;}
to {background-color: #D3E1FA;}
}

i want to trigger a animation based on css keyframes from javascript.
After reading through some answers on stackoverflow i tried using the jquery addClass function (click on the blue shape to start the animation):
https://codepen.io/valentin-wei/pen/KKMRrYK
With this approach i can only animate it once.
Is there a way to consistantly animate this shape back and forth by using javascript?
The solution you are looking for is either javascript OR wise use of css-keyframes:
In your codepen sample replace everything inside you css with this code:
test {
background-color: blue;
width:346px;
height:213px;
clip-path: polygon(323.19px 0.00px, 0.00px 186.65px, 0.00px 213.00px, 346.00px 13.17px, 323.19px 0.00px);
}
.animate {
animation-duration: 3s;
animation-name: animtest;
animation-delay: 0;
animation-iteration-count: infinite;
animation-direction: forward;
}
.reverseanimate {
animation-duration: 3s;
animation-name: animtest;
animation-delay: 0;
animation-iteration-count: infinite;
animation-direction: reverse;
}
#keyframes animtest {
0% {
clip-path: polygon(323.19px 0.00px, 0.00px 186.65px, 0.00px 213.00px, 346.00px 13.17px, 323.19px 0.00px)
}
100% {
clip-path: polygon(0.00px 168.65px, 0.00px 229.00px, 345.00px 30.17px, 292.64px 0.00px, 0.00px 168.65px)
}
}
then, replace everything inside you js with this code:
let target = document.getElementById('test');
setInterval(function(){
if ($(target).hasClass("animate")) {
$(target).removeClass("animate");
$(target).addClass("reverseanimate");
}
else {
$(target).addClass("animate");
$(target).removeClass("reverseanimate");
}
}, 3000);
NOTE: I couldn't make an account in codepen for some reason
After some further research i was able to fix this problem.
Instead of using the css animation property i use a transition now:
.animate {
transition: clip-path 3s;
clip-path: polygon(0.00px 168.65px, 0.00px 229.00px, 345.00px 30.17px, 292.64px 0.00px, 0.00px 168.65px)
}
.reverseanimate {
transition: clip-path 3s;
clip-path: polygon(323.19px 0.00px, 0.00px 186.65px, 0.00px 213.00px, 346.00px 13.17px, 323.19px 0.00px)
}
I've also updated my codepen to provide a working example: https://codepen.io/valentin-wei/pen/KKMRrYK
I'm trying to fade 2 different images on the same page with a different delay. The first image appears and then the second one appears.
Here's my fiddle :http://jsfiddle.net/jarod51/4RvWY/3/
the css:
.panel img {
opacity:0;
-moz-transition: opacity 3000ms ease-in-out;
-webkit-transition: opacity 3000ms ease-in-out;
transition: opacity 3000ms ease-in-out;
}
.shown img{
opacity: 1;
}
.img2{
opacity:0;
-moz-transition: opacity 10000ms ease-in-out;
-webkit-transition: opacity 10000ms ease-in-out;
transition: opacity 10000ms ease-in-out;
}
.shown1 img2{
opacity: 1;
}
the html :
<div id="home" class="panel">
<h2>Home</h2>
<img src="http://lorempixum.com/200/200/people/3"/>
<img class="img2" src="http://lorempixum.com/200/200/people/1"/>
</div>
my jquery attempt:
$('#wrap').find('.shown').removeClass('shown');
$target.addClass('shown');
$('#wrap').find('.shown1').removeClass('shown1');
$target.addClass('shown1');
There's a couple of things you may fix to get it working:
1) You're missing a dot (.) before the img2 in the .shown1 img2 rule. You're referring to a class and not to an HTML tag. That must be like this:
.shown1 .img2{
opacity: 1;
}
2) If you want to apply a delay to the CSS transition, you can specify it after the duration in the shorthand transition property, or in the transition-delay property. For example, for a 2s delay you can use:
.panel .img2{
opacity:0;
-moz-transition: opacity 10000ms 2s ease-in-out;
-webkit-transition: opacity 10000ms 2s ease-in-out;
transition: opacity 10000ms 2s ease-in-out;
}
See it in action here: http://jsfiddle.net/FL3RK/2/
Anyway, IMHO it would be nicer if you use the same duration (3000ms or 3s) for both transitions.
EDIT: If you don't want to wait for the animation to be completed to start it over again, put the transition property in your .shown1 .img2 rule like this:
.shown1 .img2{
opacity: 1;
-moz-transition: opacity 3000ms 2s ease-in-out;
-webkit-transition: opacity 3000ms 2s ease-in-out;
transition: opacity 3000ms 2s ease-in-out;
}
Working fiddle: http://jsfiddle.net/FL3RK/3/
var finished = 0;
var callback = function (){
// Do whatever you want.
finished++;
}
$(".div"+finished).animate(params, duration, null, callback);
html
<img src="http://lorempixum.com/200/200/people/2"/>
<img src="http://lorempixum.com/200/200/people/1"/>
<img src="http://lorempixum.com/200/200/people/2"/>
<img src="http://lorempixum.com/200/200/people/4"/>
css
img {display:none;}
script
$("img").each(function(i) {
$(this).fadeIn(2000*(i+1));
});
see the fiddle http://jsfiddle.net/vishnurajv/px7U5/
<script type="text/javascript">
$(document).ready(function(){
$('#logo').mouseenter(function() {
$('#logo').fadeTo("fast",0.3);
});
$('#logo').mouseleave(function() {
$('#logo').fadeTo("fast",1)
});
});
</script>
I made this to change the opacity of an image while hovering over it with the cursor, but this doesn't happen. :(
You don't need jQuery for that, you can use CSS:
Example HTML - you need it to have the ID logo.
<img id="logo" src="http://upload.wikimedia.org/wikipedia/commons/thumb/8/84/Example.svg/200px-Example.svg.png" />
CSS
#logo {
opacity: 1;
filter:alpha(opacity=100);
transition: opacity 0.2s linear 0s;
-webkit-transition: opacity 0.2s linear 0s;
}
#logo:hover {
opacity: 0.3;
filter:alpha(opacity=30);
transition: opacity 0.2s linear 0s;
-webkit-transition: opacity 0.2s linear 0s;
}

What does you HTML look like for your image? Is it embedded in other divs?
SO: Jquery mouseenter() vs mouseover()
As gilly3 states in the question above, "Each time your mouse enters or leaves a child element, mouseover is triggered, but not mouseenter".
I'm having a small issue with my code. I have an element that when the page scrolls it will appear. However, I cannot get it to "appear" in a smoother way. I have tried CSS transitions and attempted fadeIn but neither work. It always just "jumps" in, I cannot get it to ease in.
Here is the code:
$(window).on("scroll", function () {
$('.navbar').toggleClass('visible', $(document).scrollTop() > 40);
});
So it appears just fine, but I can't figure out how to animate adding the class name.
This is the CSS btw:
.navbar {
visibility: hidden;
}
.navbar.visible {
visibility: visible;
}
visibility can't be animated with CSS transitions.
But you can do :
.navbar {
opacity: 0;
transition: opacity .5s ease; // Feel free to use prefixes.
}
.navbar.visible {
opacity: 1;
}
CSS transition / animations is surely the best way to animate something in 2014. You should avoid fadeToggle() and others jQuery animation methods.
instead of using toggleClass, use fadeToggle. it will do everything for u as far as CSS..
give it a try, just fadeToggle();
Here is the example of your code with correct css transition. You cannot animate visibility, but you can play with position and opacity.
http://jsfiddle.net/xZ6fm/
.navbar {
position: fixed;
top: -100px;
left: 0; right: 0;
padding: 12px;
opacity: 0;
background: #ccc;
}
.navbar.visible {
top: 0;
opacity: 1;
-webkit-transition: top 0.3s linear, opacity 0.7s linear;
-moz-transition: top 0.3s linear, opacity 0.7s linear;
transition: top 0.3s linear, opacity 0.7s linear;
}
As indicated in the other answer, fadeToggle() will get the work done for you. And frankly, it's probably the easiest way to accomplish such an effect.
CSS transitions require the transition property. Place this block of code in each of your CSS declarations:
transition: visibility .25s linear;
-webkit-transition: visibility .25s linear;
-moz-transition: visibility .25s linear;
-o-transition: visibility .25s linear;
If you have difficulties with visibility, try using opacity instead.
I've been using HTML5 and Css3 to build an animated banner, but I have a few issues I can't find a work around for at the moment.
Heres a quick bit of code to use for an example, imagine this is a div layer with an image assigned to it.
First off is Opacity, it works until the end of the timeline animation then re-appears, is there a css way to get round this or would I have to use javascript?
Secondly is transition delay, I would of thought I could do a keyframe delay and freeze it for a few seconds inbetween each transition, but it never takes effect. If anyone can help I'd aprpeaciate it!
#-webkit-keyframes animation {
0% {
opacity:1;
-webkit-animation-timing-function: ease;
-webkit-transform: translateY(0px);
}
50% {
-webkit-transition-delay:10s;
opacity:1;
-webkit-animation-timing-function: ease-in;
-webkit-transform: translateY(300px);
}
100% {
opacity:0;
-webkit-animation-timing-function: ease-inout;
-webkit-transform: translateY(900px);
}
}
#animation {
-webkit-animation-delay: 0s;
-webkit-animation-duration: 6s;
-webkit-animation-iteration-count: infinite;
-webkit-animation-name: animation
}
FIrst off is the delay command, Transition-delay and animation-delay, both
*******Update************
Opacity is solved, to get it to finish after the animation, have your First frame 0% set to opacity 0. If that's a problem set a frame to 1% set it to opacity 1.
Then add forwards on the end of your animation i've been doinbg it shorthand so something like this.
#bannerImg {
-webkit-animation: bannerImg-animation1 3s 0s 1 ease-in-out forwards}
I couldn't find a way to make the code nice to look at but since starting delays and animations from within an animation itself does not seem to work I stuck the following together:
#-webkit-keyframes animation {
0% {
opacity:1;
-webkit-animation-timing-function: ease;
-webkit-transform: translateY(0px);
}
18.75% {
opacity:1;
-webkit-animation-timing-function: ease-in;
-webkit-transform: translateY(300px);
}
81.25% {
opacity:1;
-webkit-animation-timing-function: ease-in;
-webkit-transform: translateY(300px);
}
100% {
opacity:0;
-webkit-animation-timing-function: ease-inout;
-webkit-transform: translateY(900px);
}
}
#animation {
-webkit-animation-delay: 0s;
-webkit-animation-duration: 16s;
-webkit-animation-iteration-count: infinite;
-webkit-animation-name: animation;
}
JSFiddle
This solution just uses 18.75% and 81.25% as markers for the delay, changing nothing during that time (10 seconds).
