So I want to make a pop-up book effect but in 2D only. (so NOT like the beercamp page).
Ideal results:
bottom of img stays in the same position
img starts invisible then is popped up (imagine it lying on its back, then being lifted up till it is vertical)
Item should not appear too (if possible) compressed
I've read into CSS animations, the closest animation I can find is
transform: rotateX(xdeg);
So I produced this to test it out:
<!doctype html>
<style type="text/css">
#popup
{
transform: rotateX(90deg);
animation-delay: 2s;
animation-duration: 3s;
animation-name: popupanim;
animation-iteration-count: infinite;
animation-direction: alternate;
}
#keyframes popupanim
{
from {
transform: rotateX(90deg);
}
to {
transform: rotateX(0deg);
}
}
</style>
<body>
<img id="popup" src="https://si0.twimg.com/profile_images/604644048/sign051.gif" width=379px height=400px/>
</body>
The problem with this is that the bottom level of the image changes, and that the image is obviously compressed.
How could I improve this to meet my needs?
(also as a side not rotate3d(xdeg, ydeg, zdeg) does not produce any output, why?)
Add a container element and use the transform-origin property to make it pivot properly:
#container {
display: inline-block;
perspective: 600px; /* Tweak this */
}
#popup {
transform: rotateX(90deg);
transform-origin: bottom;
}
Demo: http://jsfiddle.net/BEy9f/3/
You need to use a parent element (#container) to make the perspective work properly. Also, if the #popup isn't in the exact center of the element (which is why I put display: inline-block in there), it'll appear off-center in the animation.
Chrome supports 3D transformations as well, so you can add support by using the -webkit- prefix.

Hello I am trying to make a 'Sliding Pages animation', but it is just one page, or div. I want when I click a button. The div slides out of the page to the left, and comes out thorough the right.
For instance
| Animation
| <--- Div <-----
|
Here is a simple example where the div first slides out completely to the left and then comes in from the right.
It uses CSS animation to do this, for the first half of the animation sliding it to the left and out of view and for the second half sliding it in from the right.
Note, there is a little 'fiddle' at the half way point where we take the div from the left to the right, but with opacity very temporarily at 0. This is to prevent any possibility of a slight 'flash' as the div is moved across the screen.
const div = document.querySelector('div');
const button = document.querySelector('button');
div.addEventListener('animationend', function() {
div.classList.remove('move');
});
button.addEventListener('click', function() {
div.classList.add('move');
});
* {
margin: 0;
}
button {
position: fixed;
z-index: 1;
}
div {
background-image: linear-gradient(to right, red, blue);
color: white;
display: flex;
align-items: center;
justify-content: center;
width: 100vw;
height: 100vh;
}
.move {
animation-name: move;
animation-duration: 2s;
animation-iteration-count: 1;
animation-fill-mode: forwards;
}
#keyframes move {
0% {
transform: translateX(0);
}
50% {
transform: translateX(-100%);
opacity: 1;
}
50.001% {
opacity: 0;
transform: translateX(100vw);
}
50.002% {
opacity: 1;
transform: translateX(100vw);
}
100% {
transform: translateX(0);
}
}
<button>Click me</button>
<div>This is the div</div>
There's not really enough information about what you're trying to achieve, and what you're already working with. Hopefully some of this helps.
Based off of your tags, I assume you're trying to achieve this with CSS alone. In which case you can use a keyframe animation to adjust the div's margin offset.
You can find more specifics about CSS animations here:
https://www.w3schools.com/css/css3_animations.asp
In order to accomodate the trigger for the keyframe animation, you could potentially create a hidden checkbox, and create a class for when it's :checked to start the animation. If you do use an animation to move the div off page, then you will probably also want to set the parent to hide overflow as well.
JavaScript would probably be cleaner, but you haven't really provided much information about what you're working with.
I have an image then I have applied the following style rules to:
.spinner {
position: absolute;
width: 600px;
height: 600px;
-webkit-transform-origin: 50% 50%;
-webkit-animation:spin 14s linear infinite;
animation:spin 14s linear infinite;
}
#-webkit-keyframes spin { 100% {-webkit-transform: rotate(-360deg);} }
#keyframes spin { 100% { -webkit-transform: rotate(-360deg); transform: rotate(-360deg);}}
In my IDE, this works perfectly fine. I then published a page to the web about 6 months ago. I loaded the page, and it worked as expected. Actually things were good, no problems or anything for all those 6 months. Then a few weeks ago I noticed a strange development -- the rotation behavior changed. I was bewildered because this page, and indeed, the entire site is static. There have been no updates to the master css file or anything for that matter that could possibly interfere with the style rules that I posted above.
Specifically what changed was instead of the image rotating in place at its center, the image now rotates about its original center position. The easiest way to imagine the change in behavior is comparing it to a clock. The center of the clock doesn't move as the hands rotate. However the minute hand and hour hands do (namely the ends of the hands that point to the time). That is what my image is doing now. It's now moving across the x and y dimensions in pixel space when it is not supposed to. It's supposed to rotate in place, staying still. There should be no movement in x or y.
I said to myself, "well this is just impossible," and thought the problem would go away by itself just as mysteriously as it came. Unfortunately it persisted for a few weeks, so I feel compelled to deal with it. Despite the absence of style rule clashes, I added !important to all the style rules that I posted above for the .spinner class as well as the #keyframes out of scope as well. This didn't help.
Now I'm starting to think it could be a browser issue? I'm using google chrome; only google chrome, I didn't include any -moz, I won't need to. My only guess is that the browser updated itself and started handling these animations differently?
Question: Why would animation:spin change spinning behavior? Is this symptomatic of some other looming issue? Is there anything I can do to make my rules more robust, other than add !important?
Chrome version: 64.0.3282.186
Update After what seemed like a billion trial and errors, I found that by setting:
.spinner {
-webkit-transform-origin: 15% 0%;
}
The image started to spin in place like it used to. Still begs the question what happened...
I examined the image to see if it's dimensions had changed somehow, but things look normal.
A bit late at 2021.5 But may be helpful for somebody. In my case it was because I removed :
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet">
and then caught that. All the followings were untouched ,the css were:
#overlay {
display: none;
align-items: center;
justify-content: center;
height: 100%;
width: 100%;
position: absolute;
z-index: 99999;
}
.myblock {
display: inline-block;
vertical-align: center;
horiz-align: center;
-webkit-animation: spin 4s linear infinite;
-moz-animation: spin 4s linear infinite;
animation: spin 4s linear infinite;
transform-origin: center center;
-moz-transform-origin: center;
width: auto;
height: auto;
}
#-moz-keyframes spin {
from { -moz-transform: rotate(0deg); }
to { -moz-transform: rotate(360deg); }
}
#-webkit-keyframes spin {
from { -webkit-transform: rotate(0deg); }
to { -webkit-transform: rotate(360deg); }
}
#keyframes spin {
from {transform:rotate(0deg);}
to {transform:rotate(360deg);}
}
html:
<body>
<div id="overlay">
<div class="myblock" style="background-color: transparent; background-blend-mode: unset">
<img src="/images/corona.png" width="150px" height="150px" style="background-blend-mode: unset"
alt="this slowpoke moves"/>
</div>
</div>
....//other divs
</div>
</body>
the js part:
function spinIt(gironPrm) {
if (gironPrm === true)
$("#overlay").css('display', 'flex')
else
$("#overlay").css('display', 'none')
}
I have no idea no care of its science and no time to figure out why it happened to me,
but its so as it is
I'm trying to make an infinite horizontal slider with 3 rows of images.
It looks like this:
But as you see when the end of the rows of images arrive, there's a huge blank space while the image finally appears again.
You can test it live here: http://jsfiddle.net/tbergeron/q596y/6/
Here's the CSS behind it:
ul.lists {
position: absolute;
left: 0;
top: 0;
white-space: nowrap;
-webkit-animation: moveSlideshow 180s linear infinite;
-moz-animation: moveSlideshow 180s linear infinite;
}
ul.lists li {
list-style: none;
display: inline-block;
}
ul.lists li img {
display: inline-block;
width: 100px;
height: 100px;
}
ul.slider2 {
top: 140px;
}
ul.slider3 {
top: 280px;
}
#-webkit-keyframes moveSlideshow {
0% {
-webkit-transform: translateX(0);
}
100% {
-webkit-transform: translateX(-300%);
}
}
#-moz-keyframes moveSlideshow {
0% {
-moz-transform: translateX(0);
}
100% {
-moz-transform: translateX(-300%);
}
}
What I'd like to happen is to never see that blank space, I would like it to roll on forever. Anyone has an idea on how to achieve this behavior?
Thanks and have a nice day.
basicly , You need to clone your elements.
At least many enough of the first ones to fill the entire width of the screen, or split into two differents tags, your elements.
So once a part of them, is gone left, you move them back to the right end to fill that empty space to keep scrolling without any gaps.
Your case requires javascript.
So many images wrapping line by line needs to clone the whole ul.
A good compromise could be to split content within two ul, so one can to next once of screen.
To duplicate the whole ul in the HTML document might not be a good idea and i would not advise to do so for text.
jQuery DEMO of your fiddle.
$(".lists.slider1").clone().appendTo("body");
$(".lists.slider2").clone().appendTo("body");
$(".lists.slider3").clone().appendTo("body");
But for small "marquee like" , you can use pseudo elements to clone the first few images.
For text of a known length(em) or known container's width , you may use text-shadow.
Pseudo and text-shadow avoid duplication of content.
Some horrible CSS example that demonstrate the cloning idea: http://dabblet.com/gist/5656795
I have an image on my website. When I hover over it I want it to do a 360 spin animation.
I'm currently doing so in CSS:-
.img-responsive:hover {
transition-duration: 2s;
transform:rotate(360deg);
}
However, when the user hovers at the edge of the image, the image rotates and is no longer being hovered over at the edge causing the image to "spasm".
How can I achieve a proper looking and stable rotation? JavaScript would work too.
You can fix it by adding small delay to your transition
Working Demo
.img-responsive:hover {
transition-duration: 2s;
transform:rotate(360deg);
transition-delay: 0.5s;
}
Update:
If you can use animation, You can do this
Updated Demo
.img-responsive {
animation: rotateme;
}
.img-responsive:hover {
animation: rotateme 5s;
}
You can make the image bigger when hovered, so that it's difficult that the user accidentally unhovers
if there is no padding or margin, set
.img-responsive:hover {
transition-duration: 2s;
-webkit-transform:rotate(360deg);
-moz-transform:rotate(360deg);
transform:rotate(360deg);
padding: 50px;
margin: -50px;
}
Increasing the padding to 50px makes sure that the mouse is still on it. Changing the margin in the same amount, but in opposite sense makes it stay at the same location.

Would like to know how to hide an div after a set of css3 animation. Here's my code:
#box {
position: absolute;
top: 200px;
left: 200px;
width: 200px;
height: 150px;
background-color: red;
}
#box:hover {
-webkit-animation: scaleme 1s;
}
#-webkit-keyframes scaleme {
0% {
-webkit-transform: scale(1);
opacity: 1;
}
100% {
-webkit-transform: scale(3);
opacity: 0;
display: none;
}
}
<div id='box'>
hover me
</div>
Here's the jsfiddle sample for better illustration:
http://jsfiddle.net/mochatony/Pu5Jf/18/
Any idea how to do hide the box permanently, best without javascript?
Unfortunately there is no best solution using only CSS3. Animations always return to theirs default values (see at Safari Developer Library).
But you can try to play with -webkit-animation-fill-mode property.
For example:
#box:hover{
-webkit-animation:scaleme 1s;
-webkit-animation-fill-mode: forwards;
}
It's at least not immediately return a box to display:block; state.
Using JavaScript you can do this by using webkitAnimationEnd event.
For example:
var myBox = document.getElementById('box');
myBox.addEventListener('webkitAnimationEnd',function( event ) { myBox.style.display = 'none'; }, false);
Example on jsFiddle
Change your animation definition to:
-webkit-animation:scaleme 1s forwards;
This is a value for the animation fill mode. A value of 'forwards' tells the animation to apply the property values defined in its last executing keyframe after the final iteration of the animation, until the animation style is removed.
Of course in your example the animation style will be removed when the hover is removed. At the moment I can see the need for a small piece of JavaScript to add a class which triggers the animation. Since the class would never be removed (until the page is reloaded) the div would stay hidden.
Since elements of CSS animations end in their original CSS state, make the original state hidden by scaling it to zero or removing its opacity:
div.container {
transform: scale(0);
-webkit-transform: scale(0);
}
or
div.container {
opacity: 0;
}
Once the animation is completed, the div will go back to its original CSS, which is hidden.
That can (kind of) be solved without using JavaScript. Since animations use keyframes, what you ask for is possible by setting the duration time to a way too high value, say 1000s, and letting you transition end at a low frame, for example 0.1%.
By doing this, the animation never ends and therefore stay in shape.
#box:hover {
-webkit-animation:scaleme 1000s;
}
#-webkit-keyframes scaleme {
0% { -webkit-transform: scale(1); opacity: 1; }
0.1%, 100% { -webkit-transform: scale(3); opacity: 0;display:none; }
}
1000s is not necessary in this particular example though. 10s should be enough for hover effects.
It is, however, also possible to skip the animation and use basic transitions instead.
#box2:hover {
-webkit-transition: all 1s;
-moz-transition: all 1s;
-o-transition: all 1s;
transition: all 1s;
-moz-transform: scale(3);
-webkit-transform: scale(3);
opacity: 0;
}
I forked your fiddle and altered it, adding the two for comparison: http://jsfiddle.net/madr/Ru8wu/3/
(I also added -moz- since there is no reason not to. -o- or -ms- might also be of interest).
