keyframe

问题 I have the following HMTL and CSS : .parent{ height: 10%; width: 100%; float: left; } .content1{ height: 100%; width: 20%; background-color: blue; float: left; } .content2{ height: 100%; width: 20%; background-color: red; float: left; } .content3{ height: 100%; width: 20%; background-color:yellow; float: left; } .content4{ height: 100%; width: 20%; background-color: green; float: left; } .content5{ height: 100%; width: 20%; background-color: orange; float: left; } .parent { animation-name:

问题 I have a fiddle (Fiddle A) in which cross-fade gallery of images happen for 2 images (2 tiles). Here is the snippets of html/css which I have used. <div class="featured-block" style="display:flex; justify-content: center;"> <a href="https://www.google.com/" class="featured-block__item cf"> <div class="featured-block__item-inner"> <figure class="featured-block__image img-fit" itemprop="image" itemscope="" itemtype="http://schema.org/ImageObject"> <img class="default-opacity" src="https://i

问题 I am making keyframe animation in CSS. The animation seems to be working very well in Chrome as the -webkit syntaxes are supported. @-webkit-keyframes title_toggle { from { background-image:url(images/title.png); } 75%{ background-image:url(images/title_hover.png); } to { background-image:url(images/title.png); } } I tried the code below for Firefox, but its not working @-moz-keyframes title_toggle { from { background-image:url(images/title.png); } 75%{ background-image:url(images/title_hover

问题 I made this http://codepen.io/adamchenwei/pen/dOvJNX and I try to apply a certain way of moving for a dom so it move for a fixed distance and stop, instead of animate and move through the whole width of the dom. However, I don't really want to fix the distance inside the css keyframe because I need to detect that distance dynamically, since my div that got animated ideally will change the width dynamically as well since that is not going always be 100% or any specific px fixed. Is there way I

问题 This is my 'very first' foray into keyframe animation. I was put off before by the alleged inability to dynamically change hard coded CSS values on the fly via JavaScript. I Googled around a bit to find it 'can' be done but with a lot of fiddly work finding, removing and replacing parts of or whole stylesheets. Anyway, here's my effort. The eventual goal of this particular script is to be the bounce of clock hand. I can already do this with transition and cubic bezier but can only get one

问题 I need to animate height, and set overflow: hidden for the first keyframe, and overflow: visible (and keep it) for the last one. I'm trying this, but at the end, overflow is still hidden . How can I solve this issue? The 2 includes are merely SCSS polifill mixins. @include keyframes(open) { 0% { height: 0; overflow: hidden; } 100% { height: $main_menu_height; overflow: visible; } } #main-menu-box { overflow: hidden; height: 0; &.opened{ @include animation('open 200ms ease-out 0s 1 normal

问题 I have the following HTML and CSS code: .parent{ height: 10%; width: 100%; float: left; position: relative; } .content1{ height: 100%; width: 20%; background-color: blue; float: left; position: absolute; } .content2{ height: 100%; width: 20%; background-color: red; float: left; animation-delay: 1s; position: absolute; } .content3{ height: 100%; width: 20%; background-color:yellow; float: left; animation-delay: 2s; position: absolute; } .content4{ height: 100%; width: 20%; background-color:

问题 I'm looking for technical documentation on how Flash manages object instances with the same name across key frames. So far, I've noticed that when the play head moves to another frame, if an object with the same name has the same type, then the instance is preserved along with its dynamically set properties. On the other hand, as soon as the play head goes to a frame where the named instance is a different type, then it creates a new instance of the new type (with the original name), and the

问题 I'm setting up a simple animation that brings up a little additional information when you hover over an image. The jQuery backup part is written and works fine, though the issue I'm having trouble with is getting the CSS3 animation to go in reverse when the user hovers out. So when you hover in it works great, but as soon as you hover out the elements just disappear. What I'd like to know is if there's a way to get them to animate backwards when the mouse hovers elsewhere. Thanks a lot!

问题 I am currently working on keyframe extraction from videos. Code : while success: success, currentFrame = vidcap.read() isDuplicate = False limit = count if count <= 10 else (count - 10) for img in xrange(limit, count): previusFrame = cv2.imread("%sframe-%d.png" % (outputDir, img)) try: difference = cv2.subtract(currentFrame, previusFrame) except: pass This gives me huge amounts of frames. Expected ouput: Calculate pixel difference between frames and then compare it with a threshold value and
