Triple dot CSS animation on a loading screen - css

I have a simple loading screen where I would like to have one dot appear at a time at the end of the text.
Unfortunately I can only get them to blink, when I would like for one to appear at a time and then start over.
I am currently using a fade in animation that looks like the following:
#keyframes fadeIn {
0% { opacity: 0 }
100% { opacity: 1 }
}
Here is a sample of what I have:
const App = () => {
return (
<h1>
Loading<span>.</span><span>.</span><span>.</span>
</h1>
)
}
ReactDOM.render(
<App />,
document.getElementById('app')
);
#keyframes fadeIn {
0% { opacity: 0 }
100% { opacity: 1 }
}
span:nth-child(1) {
opacity: 0;
animation: fadeIn 500ms infinite;
}
span:nth-child(2) {
opacity: 0;
animation: fadeIn 500ms infinite;
animation-delay: 500ms;
}
span:nth-child(3) {
opacity: 0;
animation: fadeIn 500ms infinite;
animation-delay: 1000ms;
}

<div id="app"></div>
As you can see, currently, it does show one at a time, but then just has all three of them blinking. How could I make them show one at a time, and then start over?
Thanks!

An easier idea with less of code:
.loading {
font-weight: bold;
display:inline-block;
font-family: monospace;
font-size: 30px;
clip-path: inset(0 3ch 0 0);
animation: l 1s steps(4) infinite;
}
#keyframes l {
to {
clip-path: inset(0 -1ch 0 0)
}
}
<div class="loading">Loading...</div>

Is there a conflict rule in css? My fadein keyframes works fine but my slidedown doesn't

Im using react and css. In my css file I create 2 animations:
#keyframes fadein {
0% {
visibility: hidden;
opacity: 0;
}
50% {
opacity: 0.5;
}
100% {
visibility: visible;
opacity: 1;
}
}
#keyframes slidedown {
0% {
transform: translateY(0%);
}
100% {
transform: translateY(30%);
}
}
.welcome__text {
padding: 3rem;
animation:
/* slidedown 2s ease 0s 1 normal forwards; => This one doesn't work */
/* fadein 1s ease-in 0s 1 normal forwards; => This one works */
}
here is my react file :
const Home = () => {
return (
<div className='homepage'>
<div className='welcome__text'>
<h1>Welcome</h1>
<h3> to Net's Web Game </h3>
</div>
</div>
)
}
export default Home;
My fadein keyframes works fine but my slidedown doesn't. And I don't know why. Is there any conflict css rule ?
If you're calling 2 animations on 1 element you need to separate them with commas, otherwise the last one (fadein) will just take priority as CSS is read from top to bottom, thus resulting in only 1 animation. For the animation properties, just separate them with commas as well:
#keyframes fadein {
0% {
visibility: hidden;
opacity: 0;
}
50% {
opacity: 0.5;
}
100% {
visibility: visible;
opacity: 1;
}
}
#keyframes slidedown {
0% {
transform: translateY(0%);
}
100% {
transform: translateY(30%);
}
}
.welcome__text {
padding: 3rem;
animation: slidedown 2s, fadein 1s;
animation-fill-mode: forwards;
animation-timing-function: ease 0s, ease-in 0s;
animation-direction: normal;
/* slidedown 2s ease 0s 1 normal forwards; => This one doesn't work */
/* fadein 1s ease-in 0s 1 normal forwards; => This one works */
}
<div class="welcome__text">hey there!</div>

delaying an animation for x seconds with css

I have an element I would like to fade in and fade out but show for 10 seconds.
.element {
-webkit-animation: fadeinout 2s linear forwards;
transition-delay: 10s;
animation: fadeinout 2s linear forwards;
opacity: 0;
}
#-webkit-keyframes fadeinout {
50% { opacity: 1; }
}
#keyframes fadeinout {
50% { opacity: 1; }
}
I have been trying for a while and think I have completely miss understood something.
UPDATE -----
What I'm trying to do is for the element to fade in over 2 seconds then show for 10 secs then fade out over 2 seconds.
transition-delay is wrong. It is about the transition. The equivalent of that is: animation-delay. use animation-duration: 14s for the time of running animation. or:
.element {
-webkit-animation: fadeinout 14s linear forwards;
animation: fadeinout 14s linear forwards;
opacity: 0;
width: 100px;
height: 100px;
background-color: red;
}
#-webkit-keyframes fadeinout {
14% { opacity: 1; }
86% { opacity: 1; }
100% { opacity: 0; }
}
#keyframes fadeinout {
14% { opacity: 1; }
86% { opacity: 1; }
100% { opacity: 0; }
}
<div class="element"></div>
This may be a little verbose, but if it is acceptable for your fade duration to be proportional to the duration it is shown you could use a keyframe structure like this:
#keyframes fadeinout {
0% { opacity: 0; },
10% { opacity: 1; },
90% { opacity: 1; },
100% { opacity: 0; }
}
To get a 2 second fadein, a 'stay there' for 10 seconds and then a 2 second fadeout you have an overall animation time of 14 seconds.
For the first (2 / 14) * 100% [=14.29%] you want the opacity to go from 0 to 1
For the next (10 / 14) * 100% [=71.43%] you want the opacity to stay at 1
For the last (2 / 14) * 100% [=14.29%] you want the opacity to go from 1 to 0.
So the animation keyframes look like this:
#keyframes fadeinout {
0%, 100% { opacity: 0; }
14.29%, 85.72% { opacity: 1; }
}
You don't want a delay on your animation (animation-delay just delays the start of an animation).
Current CSS does not allow us to use a calc function in the % settings in keyframes so we've had to do the calculation in advance and build it in (it didn't seem worth going to more than a couple of decimal places).
.element {
animation: fadeinout 14s linear forwards;
opacity: 0;
width: 20vmin;
height: 20vmin;
background-color: magenta;
}
#keyframes fadeinout {
0%,
100% {
opacity: 0;
}
14.29%,
85.72% {
opacity: 1;
}
}
<div class="element"></div>

CSS fade transition (no jQuery)

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.

rewrite my jquery fadein / fadeout using CSS3 only and running infinite

$(function() {
$('.text1').delay(1000).fadeIn(1500);
$('.text1').delay(600).fadeOut(1500);
$('.text2').delay(5000).fadeIn(1500);
$('.text2').delay(600).fadeOut(1500);
$('.text3').delay(10000).fadeIn(1500);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="text1">Lorem Ipsem</div>
<div class="text2">Lorem Ipsem</div>
<div class="text3">Lorem Ipsem</div>
Above is my simple jQuery animation; simple delay -> fadeIn -> delay -> fadeOut. However I find when trying to create a loop, for my animations to run continuously my code becomes way to large and bulky. I am wondering if it's at all possible to rewrite what I have above with CSS3 only, and then using the infinite option CSS allows.
I've gotten close with CSS below code however, I need to completely hide or fadeOut each line of text before new text shows.
#-webkit-keyframes slider {
0% { opacity: 0.4; }
100% { opacity: 1; }
}
#-moz-keyframes slider {
0% { opacity: 0.4; }
100% { opacity: 1; }
}
#-ms-keyframes slider {
0% { opacity: 0.4; }
100% { opacity: 1; }
}
.slider {
-webkit-animation: slider 1s alternate infinite;
-moz-animation: slider 1s alternate infinite;
-ms-animation: slider 1s alternate infinite;
}
<div class="slider">Lorem Ipsum</div>
As stated in other answers you can not achieve what you are asking using pure CSS solutions.
You can a solution like to an extensible approach (in case you want have many more child elements).
$("#fadeinout div").on("animationend", function() {
_this = jQuery(this);
// remove animation class
_this.removeClass("animate");
// If there is no next element then go to first one otherwise choose next element
var next = (_this.next().length < 1) ? _this.prevAll(':first-child') : _this.next();
// Add class to the new element
next.addClass("animate");
});
#fadeinout div {
width: 100px;
height: 100px;
background: red;
opacity: 0;
margin: 5px;
}
.animate {
animation-name: fadeinout;
animation-duration: 4s;
animation-delay: 0s;
}
#keyframes fadeinout {
50% {
opacity: 1;
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="fadeinout">
<div class='animate'></div>
<div></div>
<div></div>
<div></div>
</div>
This is the same example with many child elements animated: https://jsfiddle.net/j4zdgopr/1/
You can't really time the animation of multiple elements in css only. Well you could probably fake it with something like:
div {
width: 50px;
height: 50px;
background: #f00;
opacity: 0;
}
#d1 {
animation: d1 10s infinite;
}
#d2 {
animation: d2 10s infinite;
}
#d3 {
animation: d3 10s infinite;
}
#d4 {
animation: d4 10s infinite;
}
#keyframes d1 {
0% { opacity: 0; }
5% { opacity: 1; }
20% { opacity: 1; }
25% { opacity: 0; }
}
#keyframes d2 {
25% { opacity: 0; }
30% { opacity: 1; }
45% { opacity: 1; }
50% { opacity: 0; }
}
#keyframes d3 {
50% { opacity: 0; }
55% { opacity: 1; }
70% { opacity: 1; }
75% { opacity: 0; }
}
#keyframes d4 {
75% { opacity: 0; }
80% { opacity: 1; }
95% { opacity: 1; }
100% { opacity: 0; }
}
<div id="d1"></div>
<div id="d2"></div>
<div id="d3"></div>
<div id="d4"></div>
...but I would recommend against it. First of all I don't think the timing will be reliable - ie. it will get out of sync. Second your code will most likely be even more bulky than what you have.
So I would recommend a combination of simple CSS transitions and JS like this:
var curslide = 0;
var slides = $("#slider div");
var nextslide = function() {
slides.removeClass('shown');
if (curslide >= slides.length) curslide = 0;
slides.eq(curslide).addClass('shown');
curslide++;
setTimeout(nextslide, 3000);
}
nextslide();
#slider div {
width: 50px;
height: 50px;
background: #f00;
opacity: 0;
transition: opacity .5s linear;
}
#slider div.shown {
opacity: 1;
transition: opacity .5s .5s linear;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="slider">
<div id="d1"></div>
<div id="d2"></div>
<div id="d3"></div>
<div id="d4"></div>
</div>
With this solution you can add as many frames as needed without modifying the css or js.
I'd try playing with animation-delay, but I think it only applies to the first time the animation is run. After that, unless you write one animation for each .text element, they'll all fade in/out with the same frequency.
Would:
setInterval(function(){
$('.text1').delay(5000).fadeIn(1500);
$('.text2').delay(5000).fadeIn(1500);
$('.text3').delay(5000).fadeIn(1500);
$('.text1').delay(1000).fadeOut(1500);
$('.text2').delay(5000).fadeOut(1500);
}, 11500);
get you somewhere close?

CSS3 Animation Repeat pause before next iteration [duplicate]

I am using WOW.js and animate.css, right now I am running my CSS to Infinite. I would like know how can I make my class run for 3 seconds stop and start again to infinite?
My html:
<img src="images/fork.png" class="fork wow rubberBand" >
My CSS class:
.fork {
position: absolute;
top: 38%;
left: 81%;
max-width: 110px;
-webkit-animation-iteration-count: infinite ;
-webkit-animation-delay: 5s;
}
The solution can be in JS or CSS3.
With pure CSS3 animations, one way to add a delay between every single iteration of the animation would be to modify the keyframes setting such that they produce the required delay.
In the below snippet, the following is what is being done:
The whole duration of the animation is 6 seconds. In order to have the delay, the whole duration should be the duration for which your animation actually runs + time delay. Here, the animation actually runs for 3s, we need a 3s delay and so the duration is set as 6 seconds.
For the first 50% of the animation (that is, 3 seconds), nothing happens and the element basically holds its position. This gives the appearance of the 3 second delay being applied
For the next 25% of the animation (that is, 1.5 seconds) the element moves down by 50px using transform: translateY(50px).
For the final 25% of the animation (that is, last 1.5 seconds) the element moves up by 50px using transform: translate(0px) (back to its original position).
The whole animation is repeated infinite number of times and each iteration will end up having a 3 second delay.
div{
height: 100px;
width: 100px;
border: 1px solid;
animation: move 6s infinite forwards;
}
#keyframes move{
0% { transform: translateY(0px);}
50% { transform: translateY(0px);}
75% { transform: translateY(50px);}
100% { transform: translateY(0px);}
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/prefixfree/1.0.7/prefixfree.min.js"></script>
<div>Some content</div>
The animation-delay property introduces a delay only for the first iteration and hence it cannot be used to add delays between every iteration. Below is a sample snippet illustrating this.
div{
height: 100px;
width: 100px;
border: 1px solid;
animation: move 6s infinite forwards;
animation-delay: 3s;
}
#keyframes move{
0% { transform: translateY(0px);}
50% { transform: translateY(50px);}
100% { transform: translateY(0px);}
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/prefixfree/1.0.7/prefixfree.min.js"></script>
<div>Some content</div>
