Rotate Object every few seconds

I took this Pen: https://codepen.io/golle404/pen/BoqrEN and wanted to make it move every few seconds.
I tried this:
setTimeout(function() {
document.getElementById("move").style.transform = "rotateY(203deg)";
}, 2000);
but this moves the object once and I want to make the cube spin infinite with 3 stops.
So like the cube rotates to 203deg and should stay there for 2 seconds and move to 180deg for example - in a infinite loop.
Is there a way to do it ? Or is it not possible.

You can use a keyframe animation for this.
For example:
#keyframes rotation {
0%, 100% {
transform: rotateX(90deg) translateZ(-150px);
}
33.333% {
transform: translateZ(150px);
}
66.666% {
transform: rotateY(90deg) translateZ(150px);
}
}
And then you use it like this
.my-element {
animation: rotation 5s infinite;
}
Here it is in combination with your code from the codepen:
.container {
margin-top: 150px;
}
.news-grid {
width: 300px;
margin: auto;
}
.news-card {
width: 300px;
height: 300px;
perspective: 800px;
perspective-origin: 50% 50%;
outline: 1px solid blue;
}
.face>img {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
#experiment {
-webkit-perspective: 800px;
-webkit-perspective-origin: 50% 200px;
-moz-perspective: 800px;
-moz-perspective-origin: 50% 200px;
perspective: 800px;
perspective-origin: 50% 200px;
}
.cube {
position: relative;
margin: auto;
height: 300px;
width: 300px;
-webkit-transition: -webkit-transform 2s linear;
-webkit-transform-style: preserve-3d;
-moz-transition: -moz-transform 2s linear;
-moz-transform-style: preserve-3d;
transition: transform 2s linear;
transform-style: preserve-3d;
transform: rotateY(245deg);
animation: rotation 5s infinite;
}
.face {
position: absolute;
height: 260px;
width: 260px;
padding: 20px;
background-color: rgba(50, 50, 50, 0.7);
font-size: 27px;
line-height: 1em;
color: #fff;
border: 1px solid #555;
border-radius: 3px;
}
#keyframes rotation {
0%,
100% {
transform: rotateX(90deg) translateZ(-150px);
}
33.333% {
transform: translateZ(150px);
}
66.666% {
transform: rotateY(90deg) translateZ(150px);
}
}

You need to use setInterval, not setTimeout

Transform Rotate not working on my CSS when I added keyframes [duplicate]

I have a situation similar to this fiddle, where I have a CSS3 animation that scales an element absolute-positioned in the centre of another element. However, when the animation takes place it is off-centre, as seen by the red squares relative to blue in the example. How do I centre it? I have tried a couple of configurations around the transform-origin property, but this isn't producing the correct results.
#keyframes ripple_large {
0% {transform:scale(1); }
75% {transform:scale(3); opacity:0.4;}
100% {transform:scale(4); opacity:0;}
}
.container {
position: relative;
display: inline-block;
margin: 10vmax;
}
.cat {
height: 20vmax;
}
.center-point {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
height: 10px;
width: 10px;
background: blue;
}
.to-animate {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
border: 1px solid red;
height: 5vmax;
width: 5vmax;
transform-origin:center;
}
.one {
animation: ripple_large 2s linear 0s infinite;
}
.two {
animation: ripple_large 2s linear 1s infinite;
}
<div class='container'>
<img src='http://www.catster.com/wp-content/uploads/2017/08/Pixiebob-cat.jpg' class='cat'>
<div class='center-point'>
</div>
<div class='to-animate one'></div>
<div class='to-animate two'></div>
</div>

The issue is that you are overriding the translate transformation.
When you specify a new transformation (the one inside the animation) it override the first one. In your case you are removing the translation that is fixing the center alignment.
You need to add them to the same transform property and pay attention to the order because it's important (Why does order of transforms matter? rotate/scale doesn't give the same result as scale/rotate)
#keyframes ripple_large {
0% {
transform: translate(-50%, -50%) scale(1);
}
75% {
transform: translate(-50%, -50%) scale(3);
opacity: 0.4;
}
100% {
transform: translate(-50%, -50%) scale(4);
opacity: 0;
}
}
.container {
position: relative;
display: inline-block;
margin: 10vmax;
}
.cat {
height: 20vmax;
}
.center-point {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
height: 10px;
width: 10px;
background: blue;
transform-origin: center;
}
.to-animate {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
border: 1px solid red;
height: 5vmax;
width: 5vmax;
}
.one {
-webkit-animation: ripple_large 2s linear 0s infinite;
animation: ripple_large 2s linear 0s infinite;
}
.two {
-webkit-animation: ripple_large 2s linear 1s infinite;
animation: ripple_large 2s linear 1s infinite;
}
<div class='container'>
<img src='http://www.catster.com/wp-content/uploads/2017/08/Pixiebob-cat.jpg' class='cat'>
<div class='center-point'>
</div>
<div class='to-animate one'></div>
<div class='to-animate two'></div>
</div>
UPDATE
As commented, it's better to center your element using another method than translation to avoid changing the animation since this can be used with other elements.
Example:
#keyframes ripple_large {
0% {
transform: scale(1) ;
}
75% {
transform:scale(3) ;
opacity: 0.4;
}
100% {
transform: scale(4) ;
opacity: 0;
}
}
.container {
position: relative;
display: inline-block;
margin: 10vmax;
}
.cat {
height: 20vmax;
}
.center-point {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
height: 10px;
width: 10px;
background: blue;
transform-origin:center;
}
.to-animate {
position: absolute;
top: 0;
left: 0;
bottom:0;
right:0;
margin:auto;
border: 1px solid red;
height: 5vmax;
width: 5vmax;
}
.one {
animation: ripple_large 2s linear 0s infinite;
}
.two {
animation: ripple_large 2s linear 1s infinite;
}
<div class='container'>
<img src='http://www.catster.com/wp-content/uploads/2017/08/Pixiebob-cat.jpg' class='cat'>
<div class='center-point'>
</div>
<div class='to-animate one'></div>
<div class='to-animate two'></div>

Right now I have a White Background, I would like the Background to be Pure Black. I have tried a few things but nothing seems to work.
I am loading the GIF from a URL.
I know that the color code for Black is #000000 and I have tried entering it instead of the opacity = 0; but nothing seems to work.
Any advice ?

Add this style
html {
height: 100%;
background-color: black;
}

html , body{ height: 100%;}
html {background-color: black;}

Spin a div but make its content not go upside down

Is there a way to make a div spin, aswell as its content, but make the content not go upside-down while rotating ?
What I mean is that the div-childs would follow the rotation of the mother-div spinning, but while remaining in the same direction (top on top, bottom on bottom).
My english isn't goog enough to articulate properly what I want to do, so here is an exemple :
.spin {
margin: 50px;
width: 200px;
height: 200px;
background: orange;
animation: spin 10s infinite linear;
}
#div1 {
border: 1px solid blue;
width: 50px;
height: 50px;
}
#div2 {
border: 1px solid red;
width: 50px;
height: 50px;
position: absolute;
top: 0;
right: 0;
}
#div3 {
border: 1px solid black;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
left: 0;
}
#div4 {
border: 1px solid green;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
right: 0;
}
.spin:hover {
animation-play-state: paused;
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(359deg);
}
}
<div class="spin">
<div id="div1">hello
</div>
<div id="div2">hello
</div>
<div id="div3">hello
</div>
<div id="div4">hello
</div>
</div>
In the exemple above, the child divs are following the rotation and the spin.
I would like them not to "spin upside-down" and just follow the rotation.
I've seen these type of animation in several websites but I can't recall where exactly.
Is there a way to do this in css/js/jquery/php... ?

You can apply the same animation to the four children, but in reverse. That way, the rotation of the children counteract the rotation of the parent and the children remain upright.
For clarity, I've used animation-direction to reverse the animation:
animation-direction: reverse;
But you could include the direction in your animation shorthand, like:
animation: spin 10s reverse infinite linear;
Here's an example:
.spin {
margin: 50px;
width: 200px;
height: 200px;
background: orange;
animation: spin 10s infinite linear;
}
.spin div {
width: 50px;
height: 50px;
animation: spin 10s infinite linear;
animation-direction: reverse;
}
#div1 {
border: 1px solid blue;
}
#div2 {
border: 1px solid red;
position: absolute;
top: 0;
right: 0;
}
#div3 {
border: 1px solid black;
position: absolute;
bottom: 0;
left: 0;
}
#div4 {
border: 1px solid green;
position: absolute;
bottom: 0;
right: 0;
}
.spin:hover,
.spin:hover div {
animation-play-state: paused;
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(359deg);
}
}
<div class="spin">
<div id="div1">hello</div>
<div id="div2">hello</div>
<div id="div3">hello</div>
<div id="div4">hello</div>
</div>

Following #showdev answer, if you want the borders around the inner divs to follow the spin of the outer block and only make the text inside to stay "fixed" in position - you can use a bit of jQuery for that:
$('.spin div').each(function() {
$(this).contents().wrap('<span></span>');
});
I also added a bit of css, you can check inside the snippet:
$('.spin div').each(function() {
$(this).contents().wrap('<span></span>');
});
.spin {
margin: 50px;
width: 200px;
height: 200px;
background: orange;
animation: spin 10s infinite linear;
}
.spin div {
text-align: center;
line-height: 50px;
}
.spin div span {
animation: spin 10s infinite linear;
animation-direction:reverse;
display: inline-block;
}
#div1 {
border: 1px solid blue;
width: 50px;
height: 50px;
}
#div2 {
border: 1px solid red;
width: 50px;
height: 50px;
position: absolute;
top: 0;
right: 0;
}
#div3 {
border: 1px solid black;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
left: 0;
}
#div4 {
border: 1px solid green;
width: 50px;
height: 50px;
position: absolute;
bottom: 0;
right: 0;
}
.spin:hover, .spin:hover span {
animation-play-state: paused;
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(359deg);
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="spin">
<div id="div1">hello</div>
<div id="div2">hello</div>
<div id="div3">hello</div>
<div id="div4">hello</div>
</div>

I understood you also wanted each of 4 elements to stay in the area of their corners. This might need some extra animation to have them run around the parent edges.
Below the idea of what i understood:
.spin {
margin: 50px;
width: 200px;
height: 200px;
background: orange;
position: relative;
animation: spin 10s infinite linear;
}
.spin div {
width: 50px;
height: 50px;
}
#div1 {
border: 1px solid blue;
animation: spin1 10s infinite linear;
position: absolute;
top: 0;
left: 0;
}
#div2 {
animation: spin2 10s infinite linear;
border: 1px solid red;
position: absolute;
top: 0;
right: 0;
}
#div3 {
animation: spin3 10s infinite linear;
border: 1px solid black;
position: absolute;
bottom: 0;
left: 0;
}
#div4 {
animation: spin4 10s infinite linear;
border: 1px solid green;
position: absolute;
bottom: 0;
right: 0;
}
.spin:hover,
.spin:hover div {
animation-play-state: paused!important;/* or used id and several selectors to avoid the important and overide div#div1 {...}*/
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(359deg);
}
}
#keyframes spin1 {
0% {
transform: rotate(0deg);
}
25% {

}
75% {

}
100% {

}
<div class="spin">

Add this rule to each numbered div:
counterspin 10s infinite linear;
and then this keyframes animation
#keyframes counterspin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(-359deg);
}
}

.spin {
margin: 50px;

animation: spin 10s infinite linear;
position:relative;
}
.spin div {
margin:10px;
animation: spin 10s infinite ease-in-out;
animation-direction: reverse;
}
#div1 {
border: 1px solid blue;
width: 50px;
height: 50px;
position:absolute;
top:0;

}
.spin:hover {
animation-play-state: paused;
}
.spin:hover div {
animation-play-state: paused;
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(359deg);
}
}
<div class="spin">

you may try this
.spin {
margin: 50px;
width: 200px;
height: 200px;
background: orange;
animation: spin 10s infinite linear;
position:relative;
}
.spin div {
margin:10px;

animation-direction: reverse;
}
#div1 {
border: 1px solid blue;

width: 50px;
height: 50px;
position: absolute;
bottom: 0;
right: 0;
}
.spin:hover {
animation-play-state: paused;
}
.spin:hover div {
animation-play-state: paused;
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(359deg);
}
}

Can somebody help me with a web application for a simulation of transfer of images

I am trying to simulate a transfer of images by showing an image disappearing from the originating device and after a delay appearing on the target device. The application is for an experiment to design gestures
I have done the following that shows how an image appears and disappears when hovered upon
#pic3 {
max-width: 800px;
max-height: 500px;
width:500px; height:800px;
position:absolute;
}
#pic3 {
max-width: 800px;
max-height: 500px;
width:500px; height:800px;
position:absolute;
}
#pic4 {
width:500px; height:800px;
position:absolute;
max-width:800px;
max-height: 500px;
opacity:0;
-webkit-transition: opacity 1s;
}
#pic3:hover ~ #pic4, #pic4:hover {
opacity:1;
}

</div>

you have a typo in your html in the last img (missing ")
btw. i would try to solve it using jQuery

If you are trying to make an animation on one device - ie a desktop computer - trigger an animation on another device - ie a smartphone - you're going to need some means of communicating between the two. There will need to be some kind of session ID or other marker to facilitate communication between two separate browsers accessing content on a webpage each of them has loaded and rendered separately.
You'll be able to achieve this kind of functionality in a number of ways, but I suggest reading up on websockets using node.js.
If you're simply trying to mock it up on one screen (read: one browser, one session) then you're best off doing something like what #jbutler483 describes.

A simple Keyframe solution:
.device {
position: absolute;
height: 200px;
width: 150px;
background: gray;
border: 10px solid black;
border-radius: 5px;
top: 0;
left: 400px
}
.device:first-child {
right: auto;
left: 0;
}
img {
height: 100px;
width: 100px;
z-index: 8;
position: absolute;
top: 20px;
left: 30px;
-webkit-animation: animated 5s infinite;
animation: animated 5s infinite;
-webkit-animation-direction: linear;
/* Chrome, Safari, Opera */
animation-direction: linear;
}
#-webkit-keyframes animated {
10% {
opacity: 1;
}
30% {
opacity: 0;
left: 30px;
}
60% {
opacity: 0;
left: 430px;
}
90% {
left: 430px;
opacity: 1;
}
100% {
left: 430px;
opacity: 1;
}
}
#keyframes animated {
10% {
opacity: 1;
}
30% {
opacity: 0;
left: 30px;
}
60% {
opacity: 0;
left: 430px;
}
90% {
left: 430px;
opacity: 1;
}
100% {
left: 430px;
opacity: 1;
}
}
<div class="device"></div>
<img src="http://placekitten.com/g/300/300" />
<div class="device"></div>
My Approach
You could use Keyframes for this, and use a little magic to create a nice effect. Here I've used rotation, opacity, and movement to generate this 'movement' from one device to another.
.start,
.end {
position: absolute;
height: 250px;
background: gray;
border: 10px solid black;
border-radius: 5px;
width: 100px;
top: 0;
left: 0;
}
.end {
left: auto;
right: 0;
}
.imgMove {
background: url(http://placekitten.com/g/300/300);
background-size: 100% 100%;
height: 50px;
width: 50px;
position: absolute;
top: 100px;
left: 40px;
z-index: 8;
-webkit-animation: myfirst 3s infinite;
animation: myfirst 3s infinite;
}
#two {
background: url(http://placekitten.com/g/200/300);
-webkit-animation-delay: 0.5s;
animation-delay: 0.4s;
}
#three {
background: url(http://placekitten.com/g/300/200);
-webkit-animation-delay: 0.1s;
animation-delay: 0.6s;
}
#-webkit-keyframes myfirst {
0% {
top: 100px;
height: 50px;
width: 50px;
opacity: 0;
}
50% {
top: 10px;
height: 200px;
width: 200px;
left: calc(50% - 100px);
-webkit-transform: rotate(360deg);
opacity: 1;
}
100% {
top: 100px;
height: 50px;
width: 50px;
left: 90%;
-webkit-transform: rotate(720deg);
opacity: 0;
}
}
#keyframes myfirst {
0% {
top: 100px;
height: 50px;
width: 50px;
opacity: 0;
}
50% {
top: 10px;
height: 200px;
width: 200px;
left: calc(50% - 100px);
transform: rotate(360deg);
opacity: 1;
}
100% {
top: 100px;
height: 50px;
width: 50px;
left: 90%;
transform: rotate(720deg);
opacity: 0;
}
}
