Keyframe Animation Syntax. Learn Development at Frontend Masters Basic Declaration & Usage For the sake of brevity the rest of the code on this page will not use any prefixes, but real world usage should use all the vendor prefixes from above Multiple steps If an animation has the same starting and ending properties, one way to do that is to comma-separate the 0% and 100% values: Or, you could always tell the animation to run twice (or any even number of times) and tell the direction to alternate. Calling keyframe animation with separate properties Animation Shorthand Just space-separate all the individual values. Animation: test 1s 2s 3 alternate backwards Combine transform and animation Multiple animations You can comma-separate the values to declare multiple animations on a selector. Steps() The steps() function controls exactly how many keyframes will render in the animation timeframe.
If you use steps(10) in your animation, it will make sure only 10 keyframes happen in the allotted time. The math works out nicely there. CSS Sprite Sheet Animations with steps() There’s a little-known timing function in CSS animations that lets us break an animation into segments––or steps––instead of running it as one continuous animation from start to finish.
This function is useful for creating sprite sheet animations because we’re able to precisely display each sprite image as a frame without any easing effects inbetween. Animating with the steps() function With steps() we’re able to control the amount of keyframes rendered in an animation’s duration; it progresses the animation in equidistant steps based on the value we set. Knowing this, let’s use steps() to create a simple character sprite sheet animation. I used Illustrator artboards to create each animation frame as a separate 190×240 image, then took advantage of Compass’ spriting feature to quickly generate a horizontal sprite sheet containing all the exported images. The final animation sprite sheet Creating the animation Running the animation. CSS3 Animations with keyframes | Tizen Developers. Introduction The times when static websites were common have gone away a long time ago.
With introduction of Flash, websites became more vivid and interactive. However, Flash is being slowly replaced by HTML5 that has similar capabilities and is based on open standards. It is the future of the Web and mobile applications. To give developers possibility to create keyframe animations, W3C introduced CSS3 Animations. They allow animating HTML elements, specifically the CSS3 properties of elements. The CSS3 Animation specification is still a working draft and Tizen implements its version from March 20, 2009. Keyframes Very simple animations can be created using the CSS3 Transitions. In this sample code two frames are defined, one for the animation’s beginning (‘from’) and second for the animation’s end (‘to’). Having only two keyframes of animation is equal to using CSS3 Transitions. As you can see, we have replaced the ‘from’ keyframe with 0% and ‘to’ keyframe with 100%.
-webkit-animation. CSS3 Animations with keyframes | Tizen Developers. Transition. The transition property is a shorthand property used to represent up to four transition-related longhand properties: These transition properties allow elements to change values over a specified duration, animating the property changes, rather than having them occur immediately. Here is a simple example that transitions the background color of a <div> element on :hover: That div will take half a second when the mouse is over it to turn from red to green. Here is a live demonstration of such a transition: You can specify a particular property as we have above, or use a value of "all" to refer to transition properties. In this above example, both background and padding will transition, due to the value “all” specified for the transition-property portion of the shorthand. You may comma separate value sets to do different transitions on different properties: For the most part, the order of the values does not matter -- unless a delay is specified.

Everything here has been available in at least one browser since 2008. Firefox and Opera only started to add support in 2010, hence the reason this technology is becoming more mainstream.
