keyframe

问题 How can I pre -populate an JSON-Object which contains some css-properties. Where I need to add all not-contained properties to the previous object and the same for all next up items? The statement I need: if (property is not in object) object[property] = $('.foo').css(property); We have for example an element with the following styling: .foo { top: 0; width: 100px; } And the following keyframe -alike object: var keyframe = { 0: { top: 0 }, 1000: { top: 100 }, 2000: { width: 100 } }; Here we

问题 I was hoping someone could offer a simple solution. I am trying to save a 'labeled' frame on the timeline by storing it as a SharedObject. The user can flip between various different backgrounds on the stage by clicking a button - button one corresponds to background one, background 2 corresponds to btn two and so on... For your reference these backgrounds are stored in a sub timeline. Any tips on how to get this to store..? //// ---------------- WINDOW SWAPPER ------------------- this.but

问题 I am able to extract keyframes using ffmpeg. Something like this that I have been using: ffmpeg -i input.mp4 -vf "select='eq(pict_type\,I)" -vsync vfr -qscale:v 2 I-thumbnails-%02d.png -vf "select='eq(pict_type\,B)" -vsync vfr -qscale:v 2 B-thumbnails-%02d.png -vf "select='eq(pict_type\,P)" -vsync vfr -qscale:v 2 P-thumbnails-%02d.png Now the issue is, I would like these extracted frames to be in encode order, if possible, the way they are extracted should have a timestamp or any way to know

问题 I'm calling an animation like this: document.getElementById('banner').className = "changeColorToIndigo"; Then I've got the CSS property: div.changeColorToIndigo { animation-duration: 1s; animation-name: changeColorToIndigo; animation-fill-mode: forwards; } And the keyframes animation: @keyframes changeColorToIndigo { from {background-color: #00BBD2;} to {background-color: #3F51B5;} } But the animation goes back to it's initial state after the animation has completed, why is that? I've set the

问题 I'm very happy with the way the marquee works on my website, it works in all browsers except of Safari. What am I doing wrong? Is there anything I can do in order to play the same in Safari as well? .marquee { width: 260px; margin: 0 auto; overflow: hidden; whitespace: nowrap; fontsize: 20px; position: absolute; color: #fff; text-shadow: #000 1px 1px 0; font-family: Tahoma, Arial, sans-serif } @-webkit-keyframes marquee { 0% { -webkit-transform: translate(0, 0); } 100% { -webkit-transform:

问题 I am having an issue with timing within a CSS keyframe animation. I have it 90% there, but am having a gap between each image on appearance. I know this is a timing issue, but I can't for the life of me get the gap to disappear without breaking the current functionality. Code so far: .slider { position: relative; height: 200px; width: 300px; background: gray; overflow:hidden; } .slide, .slide img { position: absolute; top: 0; left: 0%; height: 100%; width: 100%; } .slide h1 { position:

问题 I have a keyframe animation that changes color after certain events but I can't figure out how to stop the animation after the event is done? HTML (just to call up the events): <div id="prt1"></div> <div id="prt2"></div> <div id="prt3"></div> CSS (just the styles and keyframe animations): #prt1 { height:20%; width:5%; border:1px solid black; top:50%; left:0%; animation:prt1 2s infinite; -webkit-animation:prt1 2s infinite; display:none; } @keyframes prt1 { 0% {background-color:white;} 33%

问题 I did a slow infinite CSS3 animation. It animates from top:0; to top:40px; . The error is when the animate ends, it jumps to the start point. I think it should jump with ease or ease-in but that's not happening. I tried a lot to fix this, but I failed. I need the return transition to have an ease-in effect. My Code: span { margin-left: 200px; } /** Down Slow Animation **/ @-webkit-keyframes downSlow { from { top: 0px; } to { top: 40px; } } @-moz-keyframes downSlow { from { top: 0px; } to {

问题 I have a css overlay that covers the entire viewport when a button is clicked. It fadesIn from opacity: 0 to opacity: 1 using css keyframes. The overlay is dependent upon a js plugin adding a class to the <body> element. So when that class is applied, the overlay is set to display: block I'm trying to animate this effect in reverse. So when the class is removed, the overlay fades out. I understand that I can apply multiple animations to the .overlay class, but I'm unsure how to proceed. Any
