Assistance needed with CSS3 Animation Keyframes - html

You can see what I have so far here: http://codepen.io/joe/pen/mkjxi
My goal is to make the lines of text appear in a staggered way, giving a nice effect to the homepage of a site.
My problem is that the 3 bottom lines of text end up reverting back to white. The reason I had made the text transition from white to black is only because I couldn't get display:none or visibility:hidden; to work with the keyframes...
Any help is greatly appreciated! Thanks

The trick is to make use of the forwards value in the animation shorthand property. This changes the fill mode and keeps the last keyframe visible after the animation has run.
Also, there is no need to use separate animations, you could do it with only one. Here is how:
<!-- HTML -->
<div class="text1">Expert Electricians.</div>
<div class="text2">Serving all of Los Angeles,</div>
<div class="text3">Ventura and Orange Counties</div>
<div class="text4">For over 20 years</div>
​
/* CSS */
div {
color: #fff;
text-transform:uppercase;
}
.text1 {
-webkit-animation:text 2s .5s forwards;
-moz-animation:text 2s .5s forwards;
-o-animation:text 2s .5s forwards;
animation:text 2s .5s forwards;
}
.text2 {
-webkit-animation:text 2s 1s forwards;
-moz-animation:text 2s 1s forwards;
-o-animation:text 2s 1s forwards;
animation:text 2s 1s forwards;
}
.text3 {
-webkit-animation:text 2s 1.5s forwards;
-moz-animation:text 2s 1.5s forwards;
-o-animation:text 2s 1.5s forwards;
animation:text 2s 1.5s forwards;
}
.text4 {
-webkit-animation:text 2s 2s forwards;
-moz-animation:text 2s 2s forwards;
-o-animation:text 2s 2s forwards;
animation:text 2s 2s forwards;
}
#-webkit-keyframes text {
100% {color:#000;}
}
#-moz-keyframes text {
100% {color:#000;}
}
#-o-keyframes text {
100% {color:#000;}
}
#keyframes text {
100% {color:#000;}
}​

svg animation not displaying properly in Chrome

I've created a CSS SVG animation of a frame being drawn onto the stage. The animation works correctly, but there seems to be an issue mostly in Chrome. The stage should be blank before the animation begins and the frame, made up of 4 segments, "draws" in segment by segment. In some versions of Chrome, however, before the animation begins there are 4 dots on the stage. The dots are the beginning points of each segment of the frame and shouldn't be visible.
In a few versions of Chrome that I've tested it on (47.0.2526.106 on a Mac, 47.0.2526.83 on an Android phone, and 43.0.2357.130 for Windows), the dots are visible. In older versions of Chrome (43.0.2357.130 for Mac, for example) and in Safari and Firefox the dots are not visible. Has anyone else encountered a similar issue? Any help will be appreciated.
Here is a working example in a jsfiddle.

I don't necessarily think this is a bug, but it should certainly be fixed. Because there is a line with what seems to be a length of 0, you'd think it'd be invisible. But in these builds of Chrome, a line with a length of 0 and a positive stroke-width, will render. Just like how the browser will still render a div when it has been given a height of 0 but also a border thicker than 0.
If you want to solve the issue, You can add something like visibility: hidden; or opacity: 0; to .framePath, and then add the opposite to the animation (at 0% and 100%)

Accelerate image spinning on hover

I got an image
<div class="spin-image">
<img src="images/color-wheel.png" alt="" />
</div>
and its corresponding css
.spin-image {
-webkit-animation:spin 10s linear infinite;
-moz-animation:spin 10s linear infinite;
animation:spin 10s linear infinite;
-webkit-transition-duration: 2s; /* Safari */
transition-duration: 2s;
}
.spin-image:hover {
-webkit-animation:spin 2s linear infinite;
-moz-animation:spin 2s linear infinite;
animation:spin 2s linear infinite;
}
#-moz-keyframes spin { 100% { -moz-transform: rotate(360deg); } }
#-webkit-keyframes spin { 100% { -webkit-transform: rotate(360deg); } }
#keyframes spin { 100% { -webkit-transform: rotate(360deg); transform:rotate(360deg); } }
What I'm trying to do is to accelerate the image spinning on hover. The animation works, but the transition does not.
If you realise, this is like the animation and the hover animation are two different ones, and they reset to their virtual state of rotation in case they were running all the time you were or weren't hovering.
Unfortunatly, it is not posible to animate the transition between 2 different animation-durations.
Yet if you really really need a solution for this, you could program the animation using transition and a javascript interval that resets the positions for every turn. This way yo can reset the property and the duration of the transition at any time with javascript.
I made you a pen: http://codepen.io/vandervals/pen/aONmVL
This is the css you need:
.spin-image img{
transition: transform 2s linear;
transform: rotate(0deg);
}
.spin-image img.hover{
transition: transform 1s linear;
}
And the JS:
var vel = 2000;
var degs = 0;
var cat = document.querySelector("img");
function repeat(){
if(vel == 1000){
cat.classList.add("hover");
console.log("hover")
}else{
cat.classList.remove("hover");
console.log("nohover")
}
degs+=360;
cat.style.transform = "rotate("+degs+"deg)";
setTimeout(repeat, vel);
}
repeat();
document.querySelector("img").addEventListener("mouseenter",hovering);
function hovering(){
vel = 1000;
}
document.querySelector("img").addEventListener("mouseleave",nohovering);
function nohovering(){
vel = 2000;
}

hover and play animation once instead of looping

If you look at my code and run it.
#-webkit-keyframes circle {
from { transform:rotate(0deg); }
to { transform:rotate(180deg); }
}
#-webkit-keyframes inner-circle {
from { transform:rotate(0deg); }
to { transform:rotate(-180deg); }
}
#one {
position: absolute;
left: 500px;
top: 200px;
width:100px;
height:100px;
border-radius: 50px;
background-color: #000000;
}
#two {
width:100px;
height:100px;
margin: 0px auto 0;
color:orange;
font-size:100px;
line-height:1;
transform-origin:50% 200px;
}
#one:hover > div {
animation: circle 1s linear infinite;
-webkit-animation: circle 1s linear infinite;
}
#one:hover > div > div {
animation: inner-circle 1s linear infinite;
-webkit-animation: inner-circle 1s linear infinite;
}
</style>
<div id="one">
<div id="two"><div id="three">☻</div></div>
</div>
you will notice that the smile face keeps on looping the animation of rotating 180deg. I don't want this. I only want it to do the animation once every time I hover over the black circle. How do I do this?
If you don't want the animation to occur infinitely, remove infinite from the animation shorthand.
In addition, you will also need to add forwards in order to to prevent the animation from resetting each time. When adding forwards to the animation shorthand, you are essentially changing the property animation-fill-mode from the default value of none to forwards.
From MDN:
The animation-fill-mode CSS property specifies how a CSS animation should apply styles to its target before and after it is executing.
#one:hover > div {
animation: circle 1s linear forwards;
-webkit-animation: circle 1s linear forwards;
}
#one:hover > div > div {
animation: inner-circle 1s linear forwards;
-webkit-animation: inner-circle 1s linear forwards;
}
Change all the infinite values to the amount of times you want the animation to loop. In your case it will be once so you want to change infinite to 1.

CSS animation tricky bug in Chrome

I have the following CSS:
#-webkit-keyframes fade-out {
from { opacity: 1; }
to { opacity: 0; }
}
#-webkit-keyframes fade-in {
from { opacity: 0; }
to { opacity: 1; }
}
.intro-text-0 {
opacity: 0;
-webkit-animation: fade-in 1s linear 1s,
fade-out 1s linear 3s;
-webkit-animation-fill-mode: forwards;
}
.intro-text-1 {
opacity: 0;
-webkit-animation: fade-in 1s linear 2s,
fade-out 1s linear 4s;
-webkit-animation-fill-mode: forwards;
}
And the simple HTML code:
<div class="intro-text-0">Hello</div>
<div class="intro-text-1">Holla</div>
When I run it, "Hello" appear in 1 second and in 3 seconds instead of fading out for 1 second, it fades out instantly. Here it is on JSFiddle: http://jsfiddle.net/3er6y0df/
I tried switching it to this:
.intro-text-0 {
opacity: 0;
-webkit-animation: fade-in 1s linear 2s,
fade-out 1s linear 4s;
-webkit-animation-fill-mode: forwards;
}
And it works perfectly.
I must mention, that this bug appeared only in Chrome (Version 37.0.2062.120 Built on Debian 7.6, running on Debian 7.7 (281580) (64-bit)), I check it out in Firefox and IE11 and there is no problem there.
Not really a bugfix though it could be a alternative.
Instead of animating a element with keyframes + animation on the elements itself why not put it all in the keyframe animation?
#keyframes AnimateMe {
0% { opacity:0%; }
80% { opacity:100%; }
100% { opacity:0%; }
}
I have experimented a bit and found a much simpler solution:
-webkit-animation: fade-in 1s linear 1001ms,
fade-out 1s linear 3s;
-webkit-animation-fill-mode: forwards;
Using 1001ms instead 1s (=1000ms) will not be noticed by a regular human eye :)

css3 animation not working in chrome

I have a small animation that is working in firefox, but not in webkit browsers. Maybe someone sees the mistake cause i've looked for an hour... It is part of a impress.js presentation, similar to prezi.
Thanks!
css:
#its.step.present h5{
display: inline-block;
position:absolute;
animation: aia2 5s linear infinite alternate;
-moz-animation: aia2 5s linear infinite alternate;
-webkit-animation: aia2 5s linear infinite alternate;
-ms-animation: aia2 5s linear infinite alternate;
-o-animation: aia2 5s linear infinite alternate;
-moz-animation-delay: 4s;
-webkit-animation-delay: 4s;
-ms-animation-delay: 4s;
-o-animation-delay: 4s;
animation-delay: 4s;
}
#-moz-keyframes aia2{
0%{
left:120px;
-moz-transform:scale(1) rotate(0deg);
-webkit-transform:scale(1) rotate(0deg);
-ms-transform:scale(1) rotate(0deg);
-o-transform:scale(1) rotate(0deg);
transform:scale(1) rotate(0deg);
color: red;
}
90%{
left: 580px;
-moz-transform:scale(1) rotate(2000deg);
-webkit-transform:scale(1) rotate(2000deg);
-ms-transform:scale(1) rotate(2000deg);
-o-transform:scale(1) rotate(2000deg);
transform:scale(1) rotate(2000deg);
}
100%{
left: 580px;
}
}
html:
<div id="its" class="step" data-x="850" data-y="3000" data-rotate="90" data-scale="5">
<p>
<ul>
<li>Web Development,</li>
<li>Web Design,</li>
<li>Log<h5>o</h5> Design,</li>
<li>Web Marketing,</li>
</ul>
<ul class="doua">
<li><h6>e</h6> Commerce,</li>
<li>CMS (WP, J, D),</li>
<li>Cust m Apps</li>
<li>and others.</li>
</ul>
</p>
</div>
You have to put the general animation rule after the browser specific ones:
-webkit-animation: aia2 5s linear infinite alternate;
-moz-animation: aia2 5s linear infinite alternate;
-ms-animation: aia2 5s linear infinite alternate;
-o-animation: aia2 5s linear infinite alternate;
animation: aia2 5s linear infinite alternate; /* this comes last */
And since you have -webkit-animation: aia2, -moz-animation: aia2 etc. you have to set the animation for each browser like:
#-moz-keyframes aia2{
...
}
#-webkit-keyframes aia2{
...
}
#-o-keyframes aia2{
...
}
Chrome v43 dropped the -webkit- prefix for animation so if this worked before but not now, that's probably why.
One thing to check if you're developing in Firefox is Firefox will take an animation-name in quotes, but Chrome/Edge/Safari/Webkit will not.
Acceptable ONLY in Firefox:
animation-name: 'theAni';
Acceptable in all browsers (Chrome, Edge, Safari & Firefox):
animation-name: theAni;
for each property that you want add animation you need first determine its value then you can change it in keyframe.
here is a simple code that you can try it:
<!DOCTYPE html>
<head>
<style>
#forTest {
display: inline-block;
background-color: darkcyan;
width: 500px; /* here we determine the value of property that we want add animation */
height: 30px;
animation: a1;
animation-fill-mode: forwards;
animation-duration: 5s;
}
#keyframes a1{
to {
width: 100px;
}
}
</style>
</head>
<body>
<div id="forTest"></div>
</body>
</html>
