I have the following code that does almost everything I need it to do.
.mouse {
margin-bottom:20px;
padding:5px;
overflow:hidden;
width:200px;
}
.mouse:after {
content:"";
height:2px;
display:block;
background:red;
margin-top:5px;
transform:translateX(100%);
animation: hoverOut 1.5s ease 1;
}
.mouse:hover:after {
animation: hoverIn 1.5s ease 1;
}
#keyframes hoverOut {
0% {transform:translateX(0%);}
100% {transform:translateX(100%);}
}
#keyframes hoverIn {
0% {transform:translateX(-100%);}
100% {transform:translateX(0%);}
}
<div class="mouse">watch the line below</div>
Basically when you mouse over the text, you see a line slide in from the left. When you mouse out, you see the line slide out to the right.
My problem is if you go to your browser and press the refresh button to cause a page load, you'll see a line travel off to the right. I do not want this animation effect on page load. Is there something I can do with just HTML and CSS ? I do not want to introduce Javascript unless I absolutely have to.
Instead of using an animation use a transition with the property transform and a value of scaleX.
The "trick" here is to change transform-origin on the hover state.
Basically you do this:
.mouse:after {
content: "";
transform: scaleX(0);
transition: transform 1.5s ease;
transform-origin: right;
}
.mouse:hover:after {
transform: scaleX(1);
transform-origin: left;
}
Code Snippet:
.mouse {
margin-bottom: 20px;
padding: 5px;
overflow: hidden;
width: 200px;
}
.mouse:after {
content: "";
height: 2px;
display: block;
background: red;
margin-top: 5px;
transform: scaleX(0);
transition: transform 1.5s ease;
transform-origin: right;
}
.mouse:hover:after {
transform: scaleX(1);
transform-origin: left;
}
<div class="mouse">watch the line below</div>
If you however want to use your animation as it is, you would need to use javascript.
You need to add a class once the user hovers your element, in this case .running.
The basics are this:
.mouse:after {
content: "";
transform: translateX(100%);
animation: hoverOut 1.5s ease 1;
animation-play-state: paused; /* Initial state of the animation, paused. */
animation-delay: -1.5s; /* Get the first frame of the animation, this value has to be the total duration of the animation with a negative value */
}
.mouse.running:after {
animation-play-state: running; /* When the class is added, the animation state is changed to running */
animation-delay: 0s /* Set back to normal flow. */;
}
Code Snippet:
document.querySelector(".mouse").addEventListener("mouseenter", function() {
this.classList.add("running");
});
.mouse {
margin-bottom: 20px;
padding: 5px;
overflow: hidden;
width: 200px;
}
.mouse:after {
content: "";
height: 2px;
display: block;
background: red;
margin-top: 5px;
transform: translateX(100%);
animation: hoverOut 1.5s ease 1;
animation-play-state: paused;
animation-delay: -1.5s;
}
.mouse.running:after {
animation-play-state: running;
animation-delay: 0s;
}
.mouse:hover:after {
animation: hoverIn 1.5s ease 1;
}
#keyframes hoverOut {
0% {
transform: translateX(0%);
}
100% {
transform: translateX(100%);
}
}
#keyframes hoverIn {
0% {
transform: translateX(-100%);
}
100% {
transform: translateX(0%);
}
}
<div class="mouse">watch the line below</div>
Animations always run when the element becomes visible.(or the page loads)
For something like this you want to use a transition. much more streamlined.
Here is your code using transition.
.mouse {
margin-bottom:20px;
padding:5px;
overflow:hidden;
width:200px;
}
.mouse:after {
content:"";
height:2px;
display:block;
background:red;
margin-top:5px;
transition: transform 1s;
transform:translateX(100%);
}
.mouse:hover:after {
transform:translateX(-100%);
}
</style>
</head>
<body>
<div class="mouse">watch the line below</div>
</body>
</html>

I have a little noobish CSS question If someone could share some free time to help. what I want to do is the div to stop and freeze at the position whenever I leave (hover off) my cursor, and not reset to his fixed starting position.
<script>
.rotatingDiv {
width: 50px;
height: 30px;
background-color: red;
margin: auto;
margin-top: 10rem;
cursor: pointer;
}
.rotatingDiv:hover {
animation: spin 4s linear infinite;
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
</script>
<body>
<div class="rotatingDiv"> </div>
</body>
as seen on the example the div keeps reseting to the starting position which is 0deg (default) on mouse-out, so what I want to achieve is for the div to freeze at the exact degree whenever I leave my cursor (mouse out/ hover off) from the div.
I think you wanted this thing it would be work
.rotatingDiv {
width: 50px;
height: 30px;
background-color: red;
margin: auto;
margin-top: 10rem;
cursor: pointer;
animation: spin 4s linear infinite;
animation-play-state: paused;
}
.rotatingDiv:hover {
animation: spin 4s linear infinite;
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
<body>
<div class="rotatingDiv"> </div>
</body>
I'm trying to create a visual transition between content changes in a toy SPA I'm writing. To that end, I define a simple class for animating the opacity of an element.
.fade {
transition: opacity 1.5s;
}
In my render function, I now change the opacity of my outlet div after content changes like so:
function render(content) {
var outlet = document.getElementById("outlet");
outlet.classList.remove("fade");
outlet.style.opacity = 0;
outlet.innerHTML = content;
outlet.classList.add("fade");
outlet.style.opacity = 1;
}
Unfortunately, the animation never fires. When I delay changing the opacity to 1 via setTimeout for 10ms, say, it works sometimes if I don't change the content again while the animation is still running, indicating a timing issue/race condition.
I used a similar approach in the past to fade out messages, but there I intentionally delayed changing the opacity by a few seconds so users could read the message before it starts fading out.
Pure CSS animation fadeIn
li {
position: absolute;
top: 50%;
left: 50%;
margin-top: -75px;
}
.logo {
width: 300px;
height: 150px;
background: red;
margin-left: -150px;
z-index: 30;
-webkit-animation: fade-in-slogan 4s .2s ease-in forwards;
-moz-animation: fade-in-slogan 4s .2s ease-in forwards;
animation: fade-in-slogan 4s .2s ease-in forwards;
}
.menu {
width: 600px;
height: 150px;
background: blue;
margin-left: -300px;
opacity: 0;
-webkit-animation: fade-in-menu 3s 4s ease-out forwards;
-moz-animation: fade-in-menu 3s 4s ease-out forwards;
animation: fade-in-menu 3s 4s ease-out forwards;
}
#-webkit-keyframes fade-in-slogan {
0% { opacity: 0; }
30% { opacity: 1; }
50% { opacity: 1; }
70% { opacity: 1; }
100% { opacity: 0; }
}
#-webkit-keyframes fade-in-menu {
0% { display: block; opacity: 0; }
30% { display: block; opacity: .3; }
60% { display: block; opacity: .6; }
80% { display: block; opacity: .8; }
100% { display: block; opacity: 1; }
}
<ul class"main">
<li class="logo"></li>
<li class="menu"></li>
</ul>
Try this, I hope this will solve the issue
.fade{
animation-name: example;
animation-duration: 4s;}
#keyframes example {
from {opacity:1}
to {opacity:0;}
}
div{
width:200px;
height:200px;
background:#000;
}
<html>
<head>
</head>
<body>
<div class="fade"></div>
</body>
</html>
I've solved it now inspired by Muhammad's answer. I defined the fade class as follows:
.fade {
animation-name: fadein;
animation-duration: 1.25s;
#keyframes fadein {
from {
opacity: 0;
}
to {
opacity: 1;
}
}
}
Then in the render function, I do
function render(content) {
outlet.classList.remove("fade");
outlet.innerHTML = "";
setTimeout(() => {
outlet.classList.add("fade");
outlet.appendChild(content);
}, 100);
}
Even though this adds an additional delay before the new content actually starts to fade in, it seems the most elegant and concise solution to me.
Firefox has a nice behavior when turning off animation in a transition enabled element, it takes the element wherever it is and transition back to original form.
In Chrome it just jumps without transitioning.
Why the inconsistency? Is there any way to replicate in Chrome without using too much JS?
.wrapper {
width: 400px;
height: 200px;
}
.move {
width: 100px;
height: 100px;
position: absolute;
background-color: #f66;
transition: 1s;
cursor: pointer;
}
.move {
animation: move 2s linear infinite;
}
.wrapper:hover .move {
animation: none;
}
#keyframes move {
50% {
transform: translateX(200px);
}
}
<div class="wrapper">
<div class="move"></div>
</div>
$(".spinny").bind("webkitAnimationEnd mozAnimationEnd animationEnd", function(){
$(this).removeClass("spin")
})
$(".spinny").hover(function(){
$(this).addClass("spin");
})
div {
width: 100px;
height: 100px;
background-color: #f66;
transition: 1s;
cursor: pointer;
}
.spin {
animation: spin 1s linear 1;
}
#keyframes spin {
100% {
transform: rotate(180deg);
}
}
<script src="https://code.jquery.com/jquery-3.1.0.js"></script><div class="spinny"></div>
Taken from this answer, JS can be used to add and remove classes on hover and animation finish, respectively. jQuery is used in this example, but it is not necessary for the functionality.
EDIT: Now without jQuery, this will play the animation whenever hovered over by remembering the state and checking after the end of every animation.
hover = 0;
s = document.getElementById("spinny");
s.addEventListener("animationend", function(){
s.className = "";
if (hover)
setTimeout(function(){s.className = "spin"},0);
})
s.onmouseover = function(){
s.className = "spin";
hover = 1;
}
s.onmouseout = function(){
hover = 0;
}
div {
width: 100px;
height: 100px;
background-color: #f66;
transition: 1s;
cursor: pointer;
}
.spin {
animation: spin 1s linear 1;
}
#keyframes spin {
100% {
transform: rotate(180deg);
}
}
<div id="spinny"></div>
Add transition along side your transform
.rotate {
width: 200px;
height: 200px;
transform: rotate(0deg);
transition: 0.5s ease all;
background-color: #222;
}
.rotate:hover {
transform: rotate(20deg);
transition: 0.5s ease all;
}
This should prevent it from jumping.
I was wondering if it was possible to have a looped animation that staggers each time the animation completes one full loop?
.hex{
animation: fio $animation-speed ease-in-out infinite;
transform: scale(.9);
opacity: 0;
&.one{
}
&.two{
animation-delay: $animation-speed * 1;
}
&.three{
animation-delay: $animation-speed * 2;
}
}
#keyframes fio{
0% {
opacity:0;
transform: scale(0.90);
}
50% {
opacity:1;
transform: scale(1.00);
}
100% {
opacity:0;
transform: scale(0.90);
}
}
As you can see from the code, it is currently staggering the first time it goes through the animation, however after that it just fades all 3 elements in and out at the same time. Is it possible to get it to stagger after every loop?
If you need any more information please let me know.
Thanks!
You just need to calculate the whole animation duration with all the delays and set them accordingly like this:
.hex {
animation: fio 1800ms ease-in-out infinite; /* This devided to three is the amount you want for the delay below */
animation-delay: 3600ms; /* All animation delays in one + two + three and add animation duration above to this */
transform: scale(.9);
opacity: 0;
&.one {
animation-delay: 0ms;
width: 50px;
height: 50px;
background-color: red;
}
&.two {
animation-delay: 600ms;
width: 50px;
height: 50px;
background-color: blue;
}
&.three {
animation-delay: 1200ms;
width: 50px;
height: 50px;
background-color: green;
}
}

I'd like to spin an image and I came across this video https://www.youtube.com/watch?v=nD8xqlh6Esk which gave a very simple way to spin a div on a click. I thought this would be a great method to spin an image on a page load with minimal css so tried using a :after as opposed to a :click (with 720 deg) but that didn't work. Has anyone got this approach to work on a page load rather than on a click? I've seen other methods but they need quite a bit more css.
Detail provided
[Apparently my youtube link is to a football match although for me it's to a LevelUp Tuts CSS Experiments #1 - Card Flipping Effect video.]
Basically, he flips a card through a simple transform on a hover as follows:
<div class="card"></div>
.card {
background: blue;
width: 200px;
height: 200px;
}
.card:hover {
transform: rotateY (90deg);
}
So you can spin the div with a single line, a transform, on a hover. There's no need for keyframes.
Try this:
div {
width: 100px;
height: 100px;
background: red;
animation: spin 2s infinite;
-webkit-animation: spin 2s infinite;
}
#keyframes spin{
to{
transform: rotate(360deg);
}
}
#-webkit-keyframes spin{
to{
transform: rotate(360deg);
}
<div id="d"></div>
EDIT: is this more like what you wanted?
div {
width: 100px;
height: 100px;
background: red;
animation: spin 2s forwards;
-webkit-animation: spin 2s forwards;
}
#keyframes spin{
to{
transform: rotateY(90deg);
}
}
#-webkit-keyframes spin{
to{
transform: rotateY(90deg);
}
}
<div id="d"><img src="http://img4.wikia.nocookie.net/__cb20120208185721/logopedia/images/5/54/Barclays_Premier_League_logo_(shield).gif" width="100px" height="100px"></div>
You need animation as well, not just transition:
http://jsfiddle.net/rudiedirkx/AB277/95/
The magic:
.card {
animation: spinn 5s linear infinite;
/* you don't need transition at all */
}
#keyframes spinn {
0% { transform: rotateY(0deg); }
100% { transform: rotateY(720deg); }
}
For some reason, Chrome still needs prefixes.
More info on css-tricks.
this animates the object as soon as the css and the html load:
(http://jsfiddle.net/oemtt7cr/)
#-webkit-keyframes spin {
from {
-webkit-transform: rotateY(0deg);
}
to {
-webkit-transform: rotateY(720deg);
}
}
#keyframes spin {
from {
transform: rotateY(0deg);
}
to {
transform: rotateY(720deg);
}
}
.container {
-webkit-perspective: 2000px;
}
.card {
margin: 20px;
background: #990;
width: 200px;
height: 200px;
animation: spin 5s ease;
-webkit-animation: spin 5s ease;
}
<div class="container">
<div class="card">flipy</div>
</div>
Use .card:hover instead of .card:after if you like the animation start when user move in with cursor.
http://jsfiddle.net/AB277/90/
.card {margin 20px;
background: blue;
width: 200px;
height:200px;
transition: all 5s;
}
.card:hover {
transform: rotateY(720deg);
}
Or if you like the animation at page load, use the following script.
http://jsfiddle.net/AB277/93/
<div id="card"
</div>
var elm = document.getElementById('card');
elm.classList.add('cardMove');
#card {margin 20px;
background: blue;
width: 200px;
height:200px;
transition: all 5s;
}
.cardMove {
transform: rotateY(720deg);
}
