Simple css animations6/12/2023 ![]() ![]() If from/ 0% or to/ 100% is not specified, the browser starts or finishes the animation using the computed values of all attributes. Because these two times are so important, they have special aliases: from and to. 0% indicates the first moment of the animation sequence, while 100% indicates the final state of the animation. Since the timing of the animation is defined in the CSS style that configures the animation, keyframes use a to indicate the time during the animation sequence at which they take place. Each keyframe describes how the animated element should render at a given time during the animation sequence. This is done by establishing two or more keyframes using the at-rule. Once you’ve configured the animation’s timing, you need to define the appearance of the animation. Defining the animation sequence using keyframes ![]() animation-play-state Lets you pause and resume the animation sequence. animation-fill-mode Configures what values are applied by the animation before and after it is executing. animation-direction Configures whether or not the animation should alternate direction on each run through the sequence or reset to the start point and repeat itself. animation-iteration-count Configures the number of times the animation should repeat you can specify infinite to repeat the animation indefinitely. animation-delay Configures the delay between the time the element is loaded and the beginning of the animation sequence. animation-timing-function Configures the timing of the animation that is, how the animation transitions through keyframes, by establishing acceleration curves. animation-duration Configures the length of time that an animation should take to complete one cycle. The sub-properties of the animation property are: animation-name Specifies the name of the at-rule describing the animation’s keyframes. This does not configure the actual appearance of the animation, which is done using the at-rule as described in Defining the animation sequence using keyframes below. This lets you configure the timing, duration, and other details of how the animation sequence should progress. To create a CSS animation sequence, you style the element you want to animate with the animation property or its sub-properties. Letting the browser control the animation sequence lets the browser optimize performance and efficiency by, for example, reducing the update frequency of animations running in tabs that aren't currently visible.The rendering engine can use frame-skipping and other techniques to keep the performance as smooth as possible. Simple animations can often perform poorly in JavaScript (unless they’re well made). The animations run well, even under moderate system load.They’re easy to use for simple animations you can create them without even having to know JavaScript.There are three key advantages to CSS animations over traditional script-driven animation techniques: Animations consist of two components, a style describing the CSS animation and a set of keyframes that indicate the start and end states of the animation’s style, as well as possible intermediate waypoints. CSS animations make it possible to animate transitions from one CSS style configuration to another. ![]()
