The first step in using animation in CSS is the . When predefined transitions are not enough or just not suitable, there is CSS animation. transition property Note: No JavaScript is used in this post! The animation property has 2 parts: and . Keyframes define stages and styles of the animation and animation property assign keyframes to the element and specify how the animation will run out on the defined element. keyframes animation property Keyframes With defining keyframes you actually set steps for your animation. The syntax for this part of the animation is word followed with animation name followed by keyframe selectors and its style. @keframes @keyframes animation-name{ 0%{CSS} 50%{CSS} 100%{CSS}} An animation is created by gradually changing from one to another style set by keyframe selectors. These selectors can have value 0%-100% (or words “from” and “to” which stand for 0% and 100%). I believe it is perfectly clear that 0% presents the beginning of the animation and 100% the end. Properties you can animate are not infinite, so there is . a list of them Now, the most shocking thing about the @keyframes option: **!important** in CSS inside of the keyframes does not only make your code important but it also ignores the whole code line...! What a shock! Animation Property Once the keyframes are defined you better make sure that work pays off and use them. Inside of the selector you want to animate add property. This property is shorthand for eight animation properties. animation animation=animation-nameanimation-durationanimation-timing-functionanimation-delayanimation-iteration-countanimation-directionanimation-fill-modeanimation-play-state Main properties to add are **animation-name** and **animation-duration** . Without **animation-name** you can't link animation to keyframes and without **animation-duration** duration will be set to 0 and again, there is no animation. Other properties are used for better defining animation. The specifies the speed curve of the animation. It can be defined with pre-defined values (linear, ease, ease-in, ease-out, ease-in-out) or custom defined by or values. Animation-timing-function steps cubic-bezier property works pretty much the same as 一it defines the start of the animation. Animation-delay transition By default, the animation will be played one time. With you can change this to any number or define it as . animation-iteration-coun infinite property specifies animation cycle一whether it will be played forwards, backward or in alternate cycles. Options that define those states are , , (forward then backward) and (backward then forward). Animation-direction normal reverse alternate alternate-reverse property defines a style of the element when the animation ends or before it started. The default state is and in this state animation will not apply any styles to the animated element. The option will set the first keyframe value to the element until it starts, and last keyframe value after it ends. Options and defined separated options from . Animation-fill-mode none both forwards backwards both And finally, with you can pause the animation and play it again. So, it has 2 options, (which is default) and . animation-play-state running paused Even property is shorthand for all listed options, it is common to use it just for and and other properties list separated. animation animation-name animation-duration animation: icon-animation 2s;animation-timing-function:ease;animation-delay: 5s;animation-iteration-count:infinite;animation-direction:normal;animation-fill-mode:both;animation-play-state:running; Just for the record, it is possible to add more than one animation to the element. And just a short note about : with all animation properties and keyframes you should use . For few specific known issues check . prefixes -webkit- CanIUse Examples The animation to itself is not really a thing that has a specific purpose in the design. On the other hand, it can be used wherever, and it will always add a value. I will say that specific animation (defined with this property) is used on the special effects the most, and animation defined with the transition is used on more common elements like hover and other states. Also, some effects on hover effect, even just a line with unusual behavior is defined with animation property. So, if you need to add “that something” to your already finished design, you add a special effect to the background or on some specific elements (loader, scroll, hover…).

Animista Epilogue The animation property is, in my opinion, one of the highest CSS properties so if not because the wow effect, you need it to your “master CSS” goal.
