css-animations

I have reviewed quite a few demos and have no idea why I can't get the CSS3 spin to function. I am using the latest stable release of Chrome. The fiddle: http://jsfiddle.net/9Ryvs/1/ div { margin: 20px; width: 100px; height: 100px; background: #f00; -webkit-animation-name: spin; -webkit-animation-duration: 40000ms; -webkit-animation-iteration-count: infinite; -webkit-animation-timing-function: linear; -moz-animation-name: spin; -moz-animation-duration: 40000ms; -moz-animation-iteration-count: infinite; -moz-animation-timing-function: linear; -ms-animation-name: spin; -ms-animation-duration:

I have several animations on my site that I just realized do not even show up in Firefox or Internet Explorer. I have the background-image within the keyframes. I do this because I have different images in different percentages with the animation. Why doesn't the background-image display within the keyframes in Firefox and Internet Explorer and is there a way to make this work? As per the specs , background-image is not an animatable or a transitionable property. But it does not seem to say anything about what or how the handling should be when it is used as part of transition or animation.

I have a bar chart that animates with CSS3 and the animation currently activates as the page loads. The problem I have is that the given bar chart is placed off screen due to lots of content before it so by the time a user scrolls down to it, the animation has already finished. I was looking for ways either through CSS3 or jQuery to only activate the CSS3 animation on the bar chart when the viewer sees the chart. <div>lots of content here, it fills the height of the screen and then some</div> <div>animating bar chat here</div> If you scroll down really fast right after page load, you can see

I'm new to animating SVGs & I've come across a problem that only seems to happen in Firefox. I've created a animation here - http://codepen.io/iamali/pen/txvpo - of a sky scene. The sun should rotate & fade in & out. It works fine in Chrome, but for some reason it appears to ignore the transform-origin value in Firefox and the sun goes AWOL. Does anyone know of such an issue in Firefox? Or could it be anything else? I've tried Google all sorts of terms but there doesn't seem to be much out there on it. Thanks! transform-origin with percentage units works from Firefox 43 onwards . 来源： https:/
