Im trying to create a blink effect by using 2 images.
I have 2 photos with a person, one with eyes opened and another with eyes closed. How can i make a blinking effect?
I was hoping to make it as real as possible, trying to blink quickly and then keep the eyes opened for 3-5sec and then blink in 1sec.
Found one example that is almost what i need but not quite yet
Would really appreciate some help

I have the following SVG animation that works perfectly fine in Chrome, Safari, Firefox but the line drawing doesn't display in IE.
I tried just the line drawing without the fade or moving away from the css shorthands but no change.
Any help or suggestion would be appreciated.
http://jsfiddle.net/zpL4okys/
.path {
stroke:#fff;
fill:transparent;
stroke-width:1;
opacity: 0;
-webkit-animation: dash 1.5s linear forwards, fadeout 1.9s linear;

I'm using css to make an image appear after a certain delay time. I want to make it disappear after another delay time. I have the appear part working, but once I add the disappear part, neither of them work. Can someone tell me what I'm doing wrong, please?
html:
<img class="anim-object anim-smallcar bluebag" src="img/bluebag.gif" />
css:
.bluebag {
position: absolute;
bottom: 160px;
left: 42.25%;
opacity: 0;
animation-name: opacityOn;
animation-duration: 100ms;
animation-delay: 13.7s;
animation-fill-mode: forwards;
animation-iteration-count: 1;
animation-name: opacityOff;
animation-duration: 100ms;
animation-delay: 17.7s;
animation-fill-mode: forwards;
animation-iteration-count: 1;
}
#keyframes opacityOn {
0% {
opacity: 0;
}
100% {
opacity: 1;
}
}
#keyframes opacityOff {
0% {
opacity: 1;
}
100% {
opacity: 0;
}
}
You can add more CSS animation iterations while changing the value of your opacity on the #keyframes the 0% to 25% to 50% to 75% and finally 100%
.bluebag {
opacity: 0;
background: blue;
height: 100px;
width: 100px;
animation: opacityOn 5s normal forwards;
animation-delay: 2s;
}
#keyframes opacityOn {
0% {
opacity: 1;
}
25% {
opacity: 0;
}
50% {
opacity: 1;
}
75% {
opacity: 0;
}
100% {
opacity: 1;
}
}
<div class="anim-object anim-smallcar bluebag" src="img/bluebag.gif">aa</div>
The only change I would make to Alexandre's code is to make the opacity keyframe all one thing like this:
#keyframes opacityOnAndOff {
0% {
opacity: 0;
}
50%{
opacity: 1;
}
100% {
opacity: 0;
}
}
Depending on how long you want to spend on going to full opacity and then clearing out, you can change the percentages, so if you want a longer closing, you could change the code above to something like
#keyframes opacityOn {
0% {
opacity: 0;
}
30%{
opacity: 1;
}
100% {
opacity: 0;
}
}
Something like that ?
.bluebag {
opacity: 0;
background: blue;
height: 100px;
width: 100px;
animation: opacityOn 1s normal forwards step-end;
animation-delay: 2s;
}
#keyframes opacityOn {
0% {
opacity: 1;
}
100% {
opacity: 0;
}
}
<div class="anim-object anim-smallcar bluebag" src="img/bluebag.gif">aa</div>
CSS is not an iterative language. When you write that:
animation-name: opacityOn;
animation-duration: 100ms;
animation-delay: 13.7s;
animation-fill-mode: forwards;
animation-iteration-count: 1;
animation-name: opacityOff;
animation-duration: 100ms;
animation-delay: 17.7s;
animation-fill-mode: forwards;
animation-iteration-count: 1;
your second section override the first one.
I can make an element with an opacity of zero fade in by changing its class to .elementToFadeInAndOut with the following css:
.elementToFadeInAndOut {
opacity: 1;
transition: opacity 2s linear;
}
Is there a way I can make the element fade out after it fades in by editing css for this same class?
Use css #keyframes
.elementToFadeInAndOut {
opacity: 1;
animation: fade 2s linear;
}
#keyframes fade {
0%,100% { opacity: 0 }
50% { opacity: 1 }
}
here is a DEMO
.elementToFadeInAndOut {
width:200px;
height: 200px;
background: red;
-webkit-animation: fadeinout 4s linear forwards;
animation: fadeinout 4s linear forwards;
}
#-webkit-keyframes fadeinout {
0%,100% { opacity: 0; }
50% { opacity: 1; }
}
#keyframes fadeinout {
0%,100% { opacity: 0; }
50% { opacity: 1; }
}
<div class=elementToFadeInAndOut></div>
Reading: Using CSS animations
You can clean the code by doing this:
.elementToFadeInAndOut {
width:200px;
height: 200px;
background: red;
-webkit-animation: fadeinout 4s linear forwards;
animation: fadeinout 4s linear forwards;
opacity: 0;
}
#-webkit-keyframes fadeinout {
50% { opacity: 1; }
}
#keyframes fadeinout {
50% { opacity: 1; }
}
<div class=elementToFadeInAndOut></div>
If you need a single fadeIn/Out without an explicit user action (like a mouseover/mouseout) you may use a CSS3 animation: http://codepen.io/anon/pen/bdEpwW
.elementToFadeInAndOut {
animation: fadeInOut 4s linear 1 forwards;
}
#keyframes fadeInOut {
0% {
opacity: 0;
}
50% {
opacity: 1;
}
100% {
opacity: 0;
}
}
By setting animation-fill-mode: forwards the animation will retain its last keyframe
By setting animation-iteration-count: 1 the animation will run just once (change this value if you need to repeat the effect more than once)
I found this link to be useful: css-tricks fade-in fade-out css.
Here's a summary of the csstricks post:
CSS classes:
.m-fadeOut {
visibility: hidden;
opacity: 0;
transition: visibility 0s linear 300ms, opacity 300ms;
}
.m-fadeIn {
visibility: visible;
opacity: 1;
transition: visibility 0s linear 0s, opacity 300ms;
}
In React:
toggle(){
if(true condition){
this.setState({toggleClass: "m-fadeIn"});
}else{
this.setState({toggleClass: "m-fadeOut"});
}
}
render(){
return (<div className={this.state.toggleClass}>Element to be toggled</div>)
}
Try creating a keyframes animation for the opacity attribute of your element:
<style>
p {
animation-name: example;
animation-duration: 2s;
}
#keyframes example {
from {opacity: 2;}
to {opacity: 0;}
}
</style>
<div>
<p>[Element to fade]</p>
</div>
(You can also set the exact percentages of animations to make it fade in/out. For example, set 0% to 2 opacity, 50% to 0 opacity, and 100% to 2 opacity. A good source for this method is W3Schools # https://www.w3schools.com/css/tryit.asp?filename=trycss3_animation2 .)
Try this:
#keyframes animationName {
0% { opacity:0; }
50% { opacity:1; }
100% { opacity:0; }
}
#-o-keyframes animationName{
0% { opacity:0; }
50% { opacity:1; }
100% { opacity:0; }
}
#-moz-keyframes animationName{
0% { opacity:0; }
50% { opacity:1; }
100% { opacity:0; }
}
#-webkit-keyframes animationName{
0% { opacity:0; }
50% { opacity:1; }
100% { opacity:0; }
}
.elementToFadeInAndOut {
-webkit-animation: animationName 5s infinite;
-moz-animation: animationName 5s infinite;
-o-animation: animationName 5s infinite;
animation: animationName 5s infinite;
}
I am having a look at CSS3 keyframes and want to have a box that eases in then eases out for the specified iteration-count, this is what I have so far it eases in then disappears then eases in again.
I want the box to ease in then ease out. See my fiddle. What do I need to do to achieve this?
<div id="content">
<span class="aniamte"></span>
</div>
#keyframes reset {
0% { opacity: 0; }
100% { opacity: 0; }
}
#keyframes fade-in {
0% { opacity: 0; }
60% { opacity: 0; }
100% { opacity: 1; }
}
.aniamte {
background: red;
display: inline-block;
height: 100px;
width: 100px;
animation-name: reset, fade-in;
animation-duration: 3s;
animation-timing-function: ease-in-out;
animation-iteration-count: 5;
animation-delay: 0, 1s;
}
I believe you're looking for animation-direction:alternate, but your question is not very clear. This will make your element use the keyframes from 0% to 100% for the specified duration then go from 100% to 0% after the first iteration is complete
#keyframes fade-in {
0% { opacity: 0; }
100% { opacity: 1; }
}
.animate {
background: red;
display: inline-block;
height: 100px;
width: 100px;
animation-name: fade-in;
animation-duration: 3s;
animation-timing-function: ease-in-out;
animation-direction:alternate;
animation-iteration-count: 5;
}
Demo
I'm trying to have an ellipsis animate, and was wondering if it was possible with CSS animations...
So it might be like
Loading...
Loading..
Loading.
Loading...
Loading..
And basically just continue like that. Any ideas?
Edit: like this: http://playground.magicrising.de/demo/ellipsis.html
How about a slightly modified version of #xec's answer: http://codepen.io/thetallweeks/pen/yybGra
CSS Animation that uses steps. See MDN docs
.loading:after {
overflow: hidden;
display: inline-block;
vertical-align: bottom;
-webkit-animation: ellipsis steps(4, end) 900ms infinite;
animation: ellipsis steps(4, end) 900ms infinite;
content: "\2026";
/* ascii code for the ellipsis character */
width: 0px;
}
#keyframes ellipsis {
to {
width: 40px;
}
}
#-webkit-keyframes ellipsis {
to {
width: 40px;
}
}
<h1 class="loading">Loading</h1>
#xec's answer has more of a slide-in effect on the dots, while this allows the dots to appear instantly.
You could try to use the animation-delay property and time each ellipsis character. In this case I've put each ellipsis character in a <span class> so I can animate them separately.
I made a demo, which isn't perfect, but it shows at least what I mean :)
The code from my example:
HTML
Loading<span class="one">.</span><span class="two">.</span><span class="three">.</span>
CSS
.one {
opacity: 0;
-webkit-animation: dot 1.3s infinite;
-webkit-animation-delay: 0.0s;
animation: dot 1.3s infinite;
animation-delay: 0.0s;
}
.two {
opacity: 0;
-webkit-animation: dot 1.3s infinite;
-webkit-animation-delay: 0.2s;
animation: dot 1.3s infinite;
animation-delay: 0.2s;
}
.three {
opacity: 0;
-webkit-animation: dot 1.3s infinite;
-webkit-animation-delay: 0.3s;
animation: dot 1.3s infinite;
animation-delay: 0.3s;
}
#-webkit-keyframes dot {
0% {
opacity: 0;
}
50% {
opacity: 0;
}
100% {
opacity: 1;
}
}
#keyframes dot {
0% {
opacity: 0;
}
50% {
opacity: 0;
}
100% {
opacity: 1;
}
}
Even a more simple solution, works pretty well!
<style>
.loading::after {
display: inline-block;
animation: dotty steps(1,end) 1s infinite;
content: '';
}
#keyframes dotty {
0% { content: ''; }
25% { content: '.'; }
50% { content: '..'; }
75% { content: '...'; }
100% { content: ''; }
}
</style>
<div class="loading">Loading</div>
Just edited the content with animation instead of hiding some dots...
Demo here: https://jsfiddle.net/f6vhway2/1/
Edit:
Thanks to #BradCollins for pointing out that content is not an animatable property.
Currently, (2021) this works in Chrome/WebKit/Blink/Electron and Firefox and new version of Edge.
Short answer is "not really". However, you can play around with animating width and overflow hidden, and maybe get an effect that is "close enough". (code below tailored for firefox only, add vendor prefixes as needed).
html
<div class="loading">Loading</div>
css
.loading:after {
overflow: hidden;
display: inline-block;
vertical-align: bottom;
-moz-animation: ellipsis 2s infinite;
content: "\2026"; /* ascii code for the ellipsis character */
}
#-moz-keyframes ellipsis {
from {
width: 2px;
}
to {
width: 15px;
}
}
demo: http://jsfiddle.net/MDzsR/1/
edit
It appears chrome has issues with animating the pseudo-element. An easy fix is to wrap the ellipsis in its own element. Check out http://jsfiddle.net/MDzsR/4/
A late addition but I found a way to do this which supports centered text.
<element>:after {
content: '\00a0\00a0\00a0';
animation: progress-ellipsis 5s infinite;
}
#keyframes progress-ellipsis {
0% {
content: '\00a0\00a0\00a0';
}
30% {
content: '.\00a0\00a0';
}
60% {
content: '..\00a0';
}
90% {
content: '...';
}
}
You can animate clip (or better clip-path if you don't need IE support)
div {
display: inline-block;
font-size: 1.4rem;
}
div:after {
position: absolute;
margin-left: .1rem;
content: ' ...';
animation: loading steps(4) 2s infinite;
clip: rect(auto, 0px, auto, auto);
}
#keyframes loading {
to {
clip: rect(auto, 20px, auto, auto);
}
}
<div>Loading</div>
Well Actually there is a pure CSS way of doing this.
I got the example from CSS Tricks, but made it also to be supported in Internet Explorer (I have tested it in 10+).
Check the Demo: http://jsfiddle.net/Roobyx/AT6v6/2/

}
I found clip-path to be the cleanest, with the following benefits:
Does not use width, thus:
works independent of how wide the ellipsis is in whatever font is used.
Does not shift the layout (good for performance, and allows more text behind it without that moving around or reflow).
.loading-ellipsis:after {
overflow: hidden;
display: inline-block;
vertical-align: bottom;
animation: ellipsis-animation steps(1,end) 2s infinite;
content: "\2026"; /* ascii code for the ellipsis character */
/* Enable this to see what is going on: */
/* background-color: red; */
}
#keyframes ellipsis-animation {
0% { clip-path: inset(0 100% 0 0); }
25% { clip-path: inset(0 66.6% 0 0); }
50% { clip-path: inset(0 33.3% 0 0); }
75% { clip-path: inset(0 0 0 0); }
}
<span class="loading-ellipsis">Loading</span> More text behind it that does not move
Credits go to #AaylaSecura's comment, and I improved that to use steps(1,end). This works because I end the animation at 75%, so that the last step shows the full expansion of the ellipsis (the third dot).
(There is an implicit 100% { clip-path: inset(0 0 0 0); } behind it that need not be written.)

I did exactly what #CodeBrauer very cleanly did above, but because my text was text-align: center (this works for right, too) and I didn't want the text to move over every time a period was added, I added "punctuation spaces":
<style>
.loading::after {
display: inline-block;
animation: dotty steps(1,end) 1s infinite;
content: '';
}
#keyframes dotty {
0% { content: '\2008\2008\2008'; }
25% { content: '.\2008\2008'; }
50% { content: '..\2008'; }
75% { content: '...'; }
100% { content: '\2008\2008\2008'; }
}
</style>
