问题 It's my first time experimenting with css3 animations and I have a question regarding the following setup: Link to codepen After item3 the animation rewinds to item1 .

HTML <div id="change"> <span>item1</span> <span>item2</span> <span>item3</span> </div> CSS #change { overflow: hidden; height: 58px; color:

问题 Using CSS and Javascript (preferably not jQuery as I don't understand as well) how do I set a CSS animation to go from a pause state to a play state triggered when the user clicks a text link (href) as opposed to a button? 回答1: It is very simple. Just set the animation-play-state to paused initially and then add a class which sets the animation-play-state to running when the anchor link is clicked. Add a return false to the event handler to prevent the default action of the anchor from

问题 I have developed the following simple HMTL and CSS code which you can also find in de JSFiddle here: body { margin: 0; } .header { width: 80%; height: 10%; margin-left: 10%; position: fixed; top: 0; box-sizing: border-box; border-style: solid; border-width: 1px; background-color: yellow; } .sub_header_01 { width: 100%; height: 100%; float: left; text-align: center; box-sizing: border-box; border-style: solid; border-width: 1px; background-color: blue; } .sub_header_02 { width: 100%; height:

问题 Is it possible to create an IE10 hack for the CSS animation property? I was using this: height: 70px\9; However this doesn't work for animation . The following will stop animations working for all browsers: animation: none\9; I want to do this in my existing stylesheet, without using JavaScript or conditional stylesheets. 回答1: This has got to be one of the most peculiar edge cases in CSS I've seen yet. I have to say, hats off to you for finding — well, stumbling across — this. The reason why

问题 I'm serving up Animate.css from this CDN to my WordPress site and would like to create some CSS class overrides that will allow me to delay the amount of time that occurs, before the animation repeats. Currently, the animations are set to "infinite" repeat. Here's a live example of how the animated image just keeps repeating, very quickly. I'd like to be able to apply class="delay4" for example, if I wanted there to be a 4s delay after an animation occurs. Then after those 4s the animation

问题 I have a scenario where I need to click on a div which will give me another div with some transition, but the problem is the clicked div is getting hidden upon the transition div . I need the clicked div to slide with the transition div with the same transition effect.

How to ensure that the iteration repeats immediately after the last row animation is completed? /

问题 Looking for some help on trying to achieve a certain animation. I'm trying to create a sequence similar to the infinite expanding rings seen here. (The example rings are contracting, I'm looking to go the other direction). I've got a pretty good start thus far, I'm just not sure how to go about making it loop "smoothly", or if it's even possible with only CSS. Any tips or ideas are greatly appreciated. Thanks!

问题 I created a basic slider with animation effect, I'm using transform: translate3d to move the slider left or right and have an issue and a bit lost on how to make it loop and slide either left or right infinitely. I'm trying to make it so when you click left or right it keeps showing and rotating the images. I also wanted to have a smooth transition with z-index, but it doesn't seem possible.
