Winning on the Web with Cascading Style Sheets (CSS) Animations

Web animations can be used to attract attention, engage people better, and communicate more clearly and effectively. It can engage and hold people's attention longer than just a static web page.

The

@keyframes

Rule

When you specify CSS styles inside the @keyframes rule, the animation will gradually change form the current style to the new style at certain times.

The animation is specified by using two types keywords: from - to and

0% - 100%

NOTE: By using per cent, you can add as many style changes as you like, For Example On (0%, 20%, 40%, 80% and 100%).

Example:

To get an animation to work, you must bind the animation to an element.

.content{ 
  width: 100px;
  height: 100px;
  color: orange;
  animation-name: false;
  animation-duration: 0.3s;
 }

 @keyframes fade {
   from{ opacity: 0; }
   to{ opacity: 1; }
  }

If the animation-duration property is not specified, no animation will occur, because the default value is 0s.

Delay an Animation

The

animation-delay

property specifies a delay for the start of an animation

Iteration of an Animation

The

animation-iteration-count

property specifies the number of times an animation should run.

Direction of an Animation

The animation-direction property specifies whether an animation should be played forwards, backwards or in alternate cycles.

The animation-direction property can have the following:

normal - default
reverse - The animation is played in reverse direction(backwards)
alternate - The animation is played forwards first, then backwards
alternate-reverse - The animation is played backwards first, then forwards

Specify the Speed Curve of the Animation

The

animation-timing-function

property specifies the speed curve of the animation.

The animation-timing-function property can have the following values:

ease - Slow start, then fast, then end slowly (default)
linear - Same speed from start to end
ease-in - slow start
ease-out - Slow end
ease-in-out - Slow start and end
cubicbezier(n,n,n,n) - Lets you define your own values in a cubic-bezier function.

Specify the Fill-Mode for an Animation

Animation does not affect an element before the first keyframe is played or after the last keyframe is played. The

animation-fill-mode

property is used to override this behavior.

The

animation-fill-mode

property specifies a style for the target element when the animation is not playing (before it starts after it ends, or both)

none - Animation will not apply any styles
forwards - The element will retain the style values that are set by the last keyframe
backwards - The element will retain style values that are set by the first keyframe
both - Retain style from first and last both.

Animation Shorthand Property

.content{
   width: 100px;
   height: 100px;
   color: orange;
   /*animation: name duration timing-function delay iteration-count direction filll-mode*/
   animation: fade 0.3s ease 1s 1 reverse forwards; 
 }
