Multiple transitions css - css

I'm trying to make multiple transitions on a hover state.
http://cssdesk.com/VbVTX
I want the image to first rotate to the left by 20deg, then back to the start, and then to the right by 20deg.
I've tried:
-webkit-transform: rotate(20deg, -20deg);
and
-webkit-transform: rotate(20deg);
-webkit-transform: rotate(-20deg);
Would I be best to use a before/after?
Thanks in advance

CSS3 Keyframe animation would be better suited to make this effect, they allow you to define several states and animate between these states.
The following demo rotates the image left 20 degrees, then back to normal state, pause and rotate 20 degrees left. The animation is launched on hover.
DEMO
.whatWeDo img {
margin:9% 0;
height: 102px;
width: 100px;
}
.whatWeDo img:hover {
-webkit-animation: rotation 4s;
animation: rotation 4s;
-webkit-transform: rotate(20deg);
transform: rotate(20deg);
}
#-webkit-keyframes rotation {
0% { -webkit-transform: rotate(0deg);}
25% { -webkit-transform: rotate(-20deg);}
50% { -webkit-transform: rotate(0deg);}
75% { -webkit-transform: rotate(0deg);}
100% { -webkit-transform: rotate(20deg);}
}
#-keyframes rotation {
0% { transform: rotate(0deg);}
25% { transform: rotate(-20deg);}
50% { transform: rotate(0deg);}
75% { transform: rotate(0deg);}
100% { transform: rotate(20deg);}
}

Oscilatory Animation CSS: How to avoid abrupt transition from 100% to 0%?

I am trying to make an Oscillatory animation using css as shown below:
Here's how I have created my animation:
#keyframes rotateFeather {
0% {
transform: rotate(0deg);
}
25% {
transform: rotate(-180deg);
}
50% {
transform: rotate(-90deg);
}
75% {
transform: rotate(90deg);
}
100% {
transform: rotate(180deg);
}
}
Here is my class: (Using sccs)
.logo {
height: 5rem;
transition: all 0.3s ease;
&box {
position: absolute;
top: 4rem;
left: 4rem;
}
&:hover {
animation-name: rotateFeather;
animation-duration: 1s;
animation-iteration-count: infinite;
animation-timing-function: linear;
}
}
Here I am facing this problem: When it reaches 180deg at 100% it abruptly resets to 0 which I want to make smooth.
How is it possible to do the same?
To ensure smooth transition, We need to make sure that transformation at 0 and 100% must match with the original state:
#keyframes rotateFeather {
0% {
transform: rotate(0deg); //-30
transform-origin: bottom;
}
20% {
transform: rotate(-30deg); //-60
transform-origin: bottom;
}
40% {
transform: rotate(0deg); //-30
transform-origin: bottom;
}
60% {
transform: rotate(30deg); // 0
transform-origin: bottom;
}
80% {
transform: rotate(60deg); //30
transform-origin: bottom;
}
100% {
transform: rotate(0deg); //30
transform-origin: bottom;
}
}
This helped me to solve my issue. I am not sure, if I need to add transform-origin in every stage, if someone can elaborate better on that, that would be helpful.
Here's a simplified version of your latest animation code (with a Codepen to see it in action):
#keyframes rotateFeather {
0% {
transform: rotate(0deg);
}
20% {
transform: rotate(-30deg);
}
80% {
transform: rotate(60deg);
}
100% {
transform: rotate(0deg);
}
}
.logo {
transform-origin: bottom;
&:hover {
animation: rotateFeather 1s linear infinite;
}
}
Some points about the above tweaks:
You don't need transform-origin at every keyframe. You can set it globally.
You can roll all of your animation properties into a single shorthand rule.
You can skip keyframes that are mathematically interpolating where the animation would be going anyway (notice I omitted 40% and 60% above and it looks the same).
You don't need any transition rules on elements that you are animating with keyframes. Unless you're using it for something else, but you want to be careful to avoid attempting to animate the same property on the same element with both animation and transition simultaneously, as it will break the animation in question.

rotate in animation doesn't animate when the order of transform is not the same, why?

Here's the demo: http://codepen.io/anon/pen/WGLGyY
the DIV doesn't rotate when the keyframe is:
#keyframes test1{
0% {
transform: rotate(0) scale(1, 1) translate(0,0)
}
100% {
transform: scale(2, 2) rotate(180deg) translate(200px,200px)
}
}
when I change the keyframe to:
#keyframes test1{
0% {
transform: rotate(0) scale(1, 1) translate(0,0)
}
100% {
transform: rotate(360deg) scale(2, 2) translate(200px,200px)
}
}
It rotate again.
So what's the reason here?
I know the order may affect the transform.
Maybe because rotate(360deg) equals rotate(0); But when I change the order of transform it comes back again....
Use transform: none for your first keyframe, and it will rotate.
Here it is in action:
#keyframes test1{
0% {
transform: none;
}
100% {
transform: scale(2, 2) rotate(360deg) translate(200px,200px)
}
}
#test{
width:200px;
height: 200px;
background: red;
animation: test1 3s infinite
}
<div id="test"></div>

Translate and scale animation issue

#keyframes my-animation {
0% {
transform: translate(0, 40%) scale(0);
}
10% {
transform: scale(1.1);
}
20% {
transform: scale(1);
}
100% {
transform: translateY(0%);
}
}
I'm trying to make my element pop then move on the Y axis, but the above fails to work.
Where am I going wrong?
Transform property gets overridden during your animation. So even though the keyframe at 0% says translate by 40% in Y-axis, the second frame at 10% nullifies it. There is a movement between 0% and 10% but that is almost invisible because the element is just then coming into view.
You need to retain the translate(0, 40%) till the time the element needs to remain translated by 40% in the Y-axis. In the below snippet, I have retained it at the translated position till 20% of the animation duration and then from between 20% to 100% it goes back to the original position.
#keyframes my-animation {
0% {
transform: translate(0, 40%) scale(0);
}
10% {
transform: translate(0, 40%) scale(1.1);
}
20% {
transform: translate(0, 40%) scale(1);
}
100% {
transform: translateY(0%);
}
}
div{
height: 100px;
width: 100px;
border: 1px solid;
animation: my-animation 4s linear forwards;
}

Grow circular image using keyframes and CSS

I'm trying to grow a circular image on hover, but can't get this code to work.
I can get the circle to grow using the CSS transform but it grows immediately and is a bit ugly. Ideally I'd want there to be a 2-3000ms delay with linear growth both on hover and mouse out.
I know I can do this with JS/D3 but need to do it with CSS if possible.
Have tried
.wpb_single_image .vc_single_image-wrapper.vc_box_circle:hover
{
animation: mymove 3s normal;
}
#-webkit-keyframes mymove {
0%
{
width:250px;}
25%
{
width:260px;}
75%
{
width:270px;}
100%
{
width:280px;
}
}
and
.wpb_single_image .vc_single_image-wrapper.vc_box_circle:hover
{
animation: mymove 3s normal;
}
#-webkit-keyframes mymove {
0%
{
-webkit-transform: scale(1);
-ms-transform: scale(1);
transform: scale(1);}
}
25%
{
-webkit-transform: scale(1.033);
-ms-transform: scale(1.033);
transform: scale(1.033);}
75%
{
-webkit-transform: scale(1.066);
-ms-transform: scale(1.066);
transform: scale(1.066);}
100%
{
-webkit-transform: scale(1.1);
-ms-transform: scale(1.1);
transform: scale(1.1);
}
But neither are working.
Is there a better way to do this?
I've created a pen based on your code
Using transform: scale is a better method since it increases both width and height.
The key thing you missed out on for creating a smooth animation is the transition attribute, this needs to be applied to the element in it's normal state not it's :hover state.
I've added this transition styling:
transition: 3s ease-in-out;
Note that it's the same length as your animation timing. ease-in-out is a standard easing function, if you'd like to get more in-depth try playing around with cubic-bezier
Animation delay can be added easily with this attribute:
animation-delay:2s
Another thing which makes keyframe animations smoother is having the 0% and 100% stylings the same, so in this example the circle returns to the original scale by the time it reaches 100% which creates a nice, smooth, repeatable animation.
I've also created an alternative animation which looks even smoother, this is done by simply setting scale for the 0% and 100% points in the animation:
0%{transform: scale(1)}
100%{transform: scale(2)}
Another thing you can do is change your animation loop setting from normal to infinite alternate, checkout my second example this is using infinite alternate which makes the circle grow and shrink with no sudden snaps.
You can delay the start of an animation with animation-delay
Such as
.delay {
animation-delay:2s
}
Reference # MDN
Demo showing the difference below
.circle {
border-radius: 50%;
display: block;
}
.circle:hover {
animation: mymove 3s normal;
}
.delay:hover {
animation-delay: 2s
}
#-webkit-keyframes mymove {
0% {
-webkit-transform: scale(1);
-ms-transform: scale(1);
transform: scale(1);
}
}
25% {
-webkit-transform: scale(1.033);
-ms-transform: scale(1.033);
transform: scale(1.033);
}
75% {
-webkit-transform: scale(1.066);
-ms-transform: scale(1.066);
transform: scale(1.066);
}
100% {
-webkit-transform: scale(1.1);
-ms-transform: scale(1.1);
transform: scale(1.1);
}
#-webkit-keyframes mymove {
0% {
-webkit-transform: scale(1);
-ms-transform: scale(1);
transform: scale(1);
}
25% {
-webkit-transform: scale(1.033);
-ms-transform: scale(1.033);
transform: scale(1.033);
}
75% {
-webkit-transform: scale(1.066);
-ms-transform: scale(1.066);
transform: scale(1.066);
}
100% {
-webkit-transform: scale(1.1);
-ms-transform: scale(1.1);
transform: scale(1.1);
}
}

You can delay the start of the transition by using the transition-delay property.
div {
-webkit-transition-delay: 2s; /* Safari */
transition-delay: 2s;
}

CSS3 animation iteration count 1 vs infinite chrome compatibility

Ok. I tried to search for this question. and it's very simple. I have a css swing animation working good in firefox but not in chrome. Of course, I added the webkit prefix. but still no luck. I changed the iteration count to infinite and finally it is working, but no I don't want it to run infinitely. Is this really a bug? does anybody find a solution? here's the link to the code I made in jsfiddle .. http://jsfiddle.net/7t1uvyup/2/ and here's the actual code.
.x{
height:50px;
width:50px;
background:#000;
position:fixed;
}
.x:hover
{
-webkit-animation: swing 1s ease;
animation: swing 1s ease;
/* change webkit iteration count to infinite and it will work on chrome but of course with infinite animation */
-webkit-animation-iteration-count: 1;
animation-iteration-count: 1;
}
#-webkit-keyframes swing
{
15%
{
-webkit-transform: translateX(5px);
transform: translateX(5px);
}

I did some research.. CSS is Hardware-Accelerated..
So this is not just a weird random bug.
I ran into this problem just now. To me it seems that the animation takes place in very short period of time and many times it is not noticable to human eyes; i.e. Chrome does not respect animation duration parameter when webkit-animation-iteration-count is not infinite.
To me it doesn't seem to be a random bug. It is reliably reproducible.
Try visiting http://www.w3schools.com/css/css3_animations.asp with different browsers. Chrome shows the worst performance; CSS3 animation box does not animate; it just stays.
