CSS3 animations allows animation of most HTML elements without using JavaScript, Adobe Flash or any other software. CSS3 animation looks a little hard at first, but once you understand the basics, you will find it amazing and interesting.
The animation property in CSS can be used to animate many other CSS properties such as color, background-color, height, or width. Css3 animation is made of two component, a style describing the CSS animation and a set of @keyframes that indicate the starting and ending of the animation.
Understand the @keyframes
Simply, The @keyframes CSS at-rule lets you control the intermediate steps in a CSS animation sequence by establishing keyframes ( waypoints) along the animation sequence that must be reached by certain points during the animation.
Example:
@keyframes technig{
0%{
background-color: yellow;
}
100% {
background-color: red;
}
}
Here is a live example.
[codepen_embed height=”268″ theme_id=”0″ slug_hash=”Jksua” default_tab=”result” user=”see8ch”]See the Pen <a href=’http://codepen.io/see8ch/pen/Jksua/’>Generate @keyframes from Sass map and @mixin</a> by Chris Holder (<a href=’http://codepen.io/see8ch’>@see8ch</a>) on <a href=’http://codepen.io’>CodePen</a>.[/codepen_embed]
If you look at the above example, you will see that we have an name for our keyframe (technig). And inside that keyframe, we have 0% which define the starting point of animation. It means in 0% the background color should be yellow and till 100%, it should change to red. You can add others waypoints as well. it was just a simple example. You can learn more about keyframes here.
How CSS3 Animations Works?
An animation lets an element gradually change from one style to another. So you can use @keyframes to apply those changes on your elements. Here are all properties that you can use in you css3 animations.
| Property Name | Property Values |
| animation-timing-function | ease, ease-out, ease-in, ease-in-out, linear, cubic-bezier(x1, y1, x2, y2) (e.g. cubic-bezier(0.5, 0.2, 0.3, 1.0)) |
| animation-play-state | animation-play-state |
| animation-delay | xs or xms (replace the x with any number) |
| animation-iteration-count | x (any number) |
| animation-duration | xs or xms (replace the x with any number) |
| animation-fill-mode | forwards, backwards, both, none |
| forwards, backwards, both, none | normal, alternate |

How to use Css3 Animations?
Once you create a @keyframe and give it a name, now you can use that name the animation-name property. You can add the animation duration and other properties as well.
Example :
[codepen_embed height=”268″ theme_id=”0″ slug_hash=”Jksua” default_tab=”result” user=”see8ch”]See the Pen <a href=’http://codepen.io/see8ch/pen/Jksua/’>Generate @keyframes from Sass map and @mixin</a> by Chris Holder (<a href=’http://codepen.io/see8ch’>@see8ch</a>) on <a href=’http://codepen.io’>CodePen</a>.[/codepen_embed]
Press compile to see the compiled version. If you look at the example, we have created a @keyframes first, than we applied that @keyframes to body tag.
