keyframe

I'm pretty new to WPF but I think what I need to do is relatively simple. I need to create an image "animation", where I am changing an image source every .25 of a second. I have a folder named "animation" with images 1 to 25 png live (named 1.png, 2.png... 25.png). Each image correlate to different frame of my animation. I want to write xaml to change the image from 1 to 2, from 2 to 3, for 3 to 4 etc every .25 seconds until it gets to the 25th image, then it should loop back to the start. I most likely will need to write some c# to do this. I want it to run on a thread that can interact with

I'm trying to do a pure HTML/CSS countdown animation but I'm struggling to make it work smoothly. For now I'm only covering minutes and seconds. Notice that I'm using animation-delay property for resetting my countdown to a certain initial time. For now everything is working fine, except the digit corresponding to the x10 minutes which is not changing sync with the rest of the digits. Following I will paste my code and two codepens, a first normal version with the correct timings for a normal behaviour and another one 10 times faster so you can quickly appreciate the problem. https://codepen

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! #recent-work div { position: relative; width: 300px; height: 168px; overflow: hidden; } #recent-work div

Is there any way to write keyframes in SASS? Every example I have found is actually SCSS, even when it says it's SASS. To be clear, I mean the one with no curly brackets. Here is how you implement css keyframes in the Sass syntax: @keyframes name-of-animation 0% transform: rotate(0deg) 100% transform: rotate(360deg) Here is a Sass mixin to add vendor prefixes: =keyframes($name) @-webkit-keyframes #{$name} @content @-moz-keyframes #{$name} @content @-ms-keyframes #{$name} @content @keyframes #{$name} @content Here's how to use the mixin in Sass syntax: +keyframes(name-of-animation) 0% transform

I have an element that is red in resting state, and green when the user hovers their cursor over it. I have it set to ease the transition for 0.4s . Instead of having the colour transition straight from red to green, I'd like it to pass through yellow at the midway point. So when the user mouses over it, it goes from red to yellow to green in one smooth transition. Is this possible? This is my current code. .element { background-color: red; -webkit-transition: all 0.4s ease; transition: all 0.4s ease; } .element:hover { background-color: green; } you could use keyframes for this: .element {

I want to create an animated HTML "marquee" that scrolls back and forth on a website: <div class="marquee">This is a marquee!</div> and the CSS: .marquee { position: absolute; white-space: nowrap; -webkit-animation: rightThenLeft 4s linear; } @-webkit-keyframes rightThenLeft { 0% {left: 0%;} 50% {left: 100%;} 100% {left: 0%;} } The problem is, the marquee doesn't stop when it reaches the right-hand edge of the screen; it moves all the way off the screen (making a horizontal scroll bar appear, briefly) and then comes back. So, how do I make the marquee stop when its right-hand edge reaches the
