Animation duration? - css

I have a simple CSS marquee scrolling up across a screen, essentially using the code found here (JSFiddle):
https://jsfiddle.net/c8r5kc1L/1/
<style style="text/css">
.marquee-outer {
height: 100px;
overflow: hidden;
position: relative;
color: orange;
}
.marquee-inner {
position: absolute;
width: 100%;
height: 100%;
margin: 0;
line-height: 50px;
text-align: center;
/* Starting position */
-moz-transform:translateY(100%);
-webkit-transform:translateY(100%);
transform:translateY(100%);
/* Apply animation to this element */
-moz-animation: scroll-up 5s linear infinite;
-webkit-animation: scroll-up 5s linear infinite;
animation: scroll-up 5s linear infinite;
}
/* Move it (define the animation) */
#-moz-keyframes scroll-up {
0% { -moz-transform: translateY(100%); }
100% { -moz-transform: translateY(-100%); }
}
#-webkit-keyframes scroll-up {
0% { -webkit-transform: translateY(100%); }
100% { -webkit-transform: translateY(-100%); }
}
#keyframes scroll-up {
0% {
-moz-transform: translateY(100%); /* Browser bug fix */
-webkit-transform: translateY(100%); /* Browser bug fix */
transform: translateY(100%);
}
100% {
-moz-transform: translateY(-100%); /* Browser bug fix */
-webkit-transform: translateY(-100%); /* Browser bug fix */
transform: translateY(-100%);
}
}
</style>
<div class="marquee-outer">
<div class="marquee-inner">Text</div>
</div>
I am trying to enter several paragraphs worth of content into the actual scroll area, which means that the animation resets before I've gotten through all the content. If I increase the animation duration (say, to 100s), the animation slows down, and ends up going through the same (partial) amount to the information.
Is there a way to keep the speed of the scroll constant, but actually just increase the duration of the scroll prior to reset?

I found a solution, if you "sync" the -100% with the amount of paragraphs that you want (And uses <p> inside <div class="marquee-inner"> because it gives you more control in the scrolling animation):
100% {
transform: translateY(-100%);
}
So is you want to have 4 paragraphs do something like this:
100% {
transform: translateY(-400%);
}
And also don't use line-height: 50px; in .marquee-inner instead use margin-bottom:
.marquee-inner p{
margin-bottom: 30px;
}
Look the example: https://jsfiddle.net/u2j2679u/

CSS Transform scale 'glitchy' on firefox

I am trying to animate a line that expands both ways from the centre using transform:scale but for some reason the line kind of "rewinds" slightly when it reaches the end, but only on the right side of the line. This only seems to happen on firefox, (both on mobile and desktop) but seems fine on chrome.
<div class="line"></div>
<style>
.line {
height: 4px;
width: 5px;
background-color: #5d496a;
margin: 0 50%;
animation: line_animation 1s forwards ;
}
#keyframes line_animation {
0% {
transform: scale(1,1);
}
100%{
transform: scale(22,1);
}
}
</style>
I am still learning animations so I am not sure what I am doing wrong. Any help would be very appreciated.

Looks like it was an issue with scale being greater than 1.
Fixed by changing width: 5px; to width: 15%; and changed
#keyframes line_animation {
0% {
transform: scale(1,1);
}
100%{
transform: scale(22,1);
}
}
to
#keyframes line_animation {
from {
transform: scale(0.01,1);
}
to{
transform: scale(1,1);
}
}

List won't move with transform

I have a list that I'm trying to scroll from top to bottom (marquee fashion). I'm using this CSS:
// Marquee CSS
.scrolling
{
height: 200px;
overflow: hidden;
position: relative;
}
.scrolling a
{
position: absolute;
width: 100%;
height: 100%;
margin: 0;
text-align: center;
color: white;
/* Starting position */
-moz-transform:translateY(-100%);
-webkit-transform:translateY(-100%);
transform:translateY(-100%);
/* Apply animation to this element */
-moz-animation: scrolling 15s linear infinite;
-webkit-animation: scrolling 15s linear infinite;
animation: scrolling 15s linear infinite;
}
.scrolling ul {
position: absolute;
width: 100%;
height: 100%;
margin: 0;
text-align: center;
/* Starting position */
-moz-transform:translateY(-100%);
-webkit-transform:translateY(-100%);
transform:translateY(-100%);
/* Apply animation to this element */
-moz-animation: scrolling 15s linear infinite;
-webkit-animation: scrolling 15s linear infinite;
animation: scrolling 15s linear infinite;
}
/* Move it (define the animation) */
#-moz-keyframes scrolling {
0% { -moz-transform: translateY(0%); }
100% { -moz-transform: translateY(100%); }
}
#-webkit-keyframes scrolling {
0% { -webkit-transform: translateY(0%); }
100% { -webkit-transform: translateY(100%); }
}
#keyframes scrolling {
0% {
transform: translateY(0%);
}
100% {
transform: translateY(100%);
}
}
which works, sort of. It does scroll my list, however it hides a large portion of the list. The box size is just what I'm looking for, my list is entirely intact however it simply doesn't show the entire list when I try to scroll it. What am I doing wrong?
The solution, it seems, is to increase the size of the transform ie from -100% (or 0%) to -600% to 600% - it allows for the list to be 12X the size of my box, I think. If someone could confirm this is what I've done by changing those numbers I would certainly be grateful!

Spinning an image using rotateY

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);
}

How do I reverse this CSS rotate animation?

I have this CSS animation which I'm trying to reverse the animation of based on a class being added to a DOM node. I've tried multiple things but with no avail. Here is the code I'm using, see below:
EXAMPLE
// Closed state
#-moz-keyframes spin-close { 100% { -moz-transform: rotate(-0deg); } }
#-webkit-keyframes spin-close { 100% { -webkit-transform: rotate(-0deg); } }
#keyframes spin-close { 100% { transform:rotate(-0deg); } }
// Open state
#-moz-keyframes spin-open { 100% { -moz-transform: rotate(-90deg); } }
#-webkit-keyframes spin-open { 100% { -webkit-transform: rotate(-90deg); } }
#keyframes spin-open { 100% { transform:rotate(-90deg); } }
I don't know whether I'm looking at it all wrong? Please advise(a demo would be awesome).
Don't bother with javascript or animations. Use a CSS transition for this:
.image {
position: absolute;
top: 50%;
left: 50%;
width: 120px;
height: 120px;
margin:-60px 0 0 -60px;
transition:all 1s ease-out;
transform:rotate(0deg);
-webkit-transform:rotate(0deg); /* Safari and Chrome */
}
.image:hover {
transform:rotate(90deg);
-webkit-transform:rotate(90deg); /* Safari and Chrome */
}
http://jsfiddle.net/Ugc5g/892/
To reverse the rotation, you can simply change the degree value to the opposite value. For example, if the element is currently rotated 45 degrees clockwise, you can reverse the rotation by rotating it -45 degrees.
transform: rotate(-45deg);

CSS3 Animation to hoverstate and back

I need an element that initially has no animation, then animates to a different state on hover (one time, no loop) and after the hover is gone it should animate back to its original state.
Basically just like you would do it with a :hover style and a transition.
Is there a way to achieve that with a CSS3 animation?
This is my current usecase: http://jsfiddle.net/yjD73/11/
On hover an element fades from opacity: 0 to opacity: 1 and back.
This is what i think is not possible with transitions.
EDIT: As requested here the exact code from jsfiddle
a div with four images
<div class="zoombox">
<img src="http://maps.googleapis.com/maps/api/staticmap?sensor=false&size=300x300&maptype=hybrid&zoom=4&center=51.561998,-1.605100">
<img src="http://maps.googleapis.com/maps/api/staticmap?sensor=false&size=300x300&maptype=hybrid&zoom=7&center=51.561998,-1.605100">
<img src="http://maps.googleapis.com/maps/api/staticmap?sensor=false&size=300x300&maptype=hybrid&zoom=12&center=51.561998,-1.605100">
<img src="http://maps.googleapis.com/maps/api/staticmap?sensor=false&size=300x300&maptype=hybrid&zoom=16&center=51.562606,-1.605100">
</div>
images stacked onto each other and simple css animations on hover
.zoombox {
position: relative;
margin: 50px;
float: left;
}
/* initial state */
.zoombox img:not(:first-child) {
position: absolute;
top: 0;
opacity: 0;
}
/* On hover in */
.zoombox:hover img:nth-child(1) {
-webkit-animation: first-in 400ms 0ms 1 normal ease-in both;
}
.zoombox:hover img:nth-child(2) {
-webkit-animation: middle-in 1600ms 0ms 1 linear both;
}
.zoombox:hover img:nth-child(3) {
-webkit-animation: middle-in 1600ms 1200ms 1 linear both;
}
.zoombox:hover img:nth-child(4) {
-webkit-animation: last-in 400ms 2400ms 1 linear both;
}
#-webkit-keyframes first-in {
0% {
-webkit-transform: scale(1);
opacity: 1;
}
100% {
-webkit-transform: scale(1.5);
opacity: 0;
}
}
#-webkit-keyframes middle-in {
0% {
-webkit-transform: scale(0.5);
opacity: 0;
}
25%, 75% {
-webkit-transform: scale(1);
opacity: 1;
}
100% {
-webkit-transform: scale(1.5);
opacity: 0;
}
}
#-webkit-keyframes last-in {
0% {
-webkit-transform: scale(0.5);
opacity: 0;
}
100% {
-webkit-transform: scale(1);
opacity: 1;
}
}
Conic, I have created a JSFiddle that replicates most of what you want with css3 animations.
Here it is.
The code that makes this all possible in CSS is:
#-webkit-keyframes changeImage {
0% {background: url("http://maps.googleapis.com/maps/api/staticmap?sensor=false&size=300x300&maptype=hybrid&zoom=4&center=51.561998,-1.605100");}
33% {background: url("http://maps.googleapis.com/maps/api/staticmap?sensor=false&size=300x300&maptype=hybrid&zoom=7&center=51.561998,-1.605100");}
67% {background: url("http://maps.googleapis.com/maps/api/staticmap?sensor=false&size=300x300&maptype=hybrid&zoom=12&center=51.561998,-1.605100");}
100% {background: url("http://maps.googleapis.com/maps/api/staticmap?sensor=false&size=300x300&maptype=hybrid&zoom=16&center=51.562606,-1.605100");}
}
Right now the jsfiddle is having the image run through the animation on hover and return to the original image. Let me know if you need any over things to happen and by the way, this won't work on any touch devices as a result of a lack of hover state possibilities.
