CSS Animation

Definition: CSS Animation is used to create animation on the webpage.

• With CSS animation, you can animate various properties of HTML elements, such as position, size, colour, opacity, and more.

• However in EduBlocks, there are no specific blocks for CSS animation. Instead, you can use an empty text block to specify the animation you prefer.

What Animation Does

• An animation gradually transforms an element from one style to another, allowing for the addition of multiple properties.
• The changes can be specified using Keyframe percentages, such as 0%, 50%, and 100%, indicating the animation's progress at different stages.

How CSS Animation Works

• CSS animation works by defining keyframes that specify intermediate steps and style changes at different points in time.
• These keyframes are defined using the @keyframes rule. Within the keyframes, you can specify the CSS properties and values that you want to animate.
• This can be done by specifying at least two properties:
  • The name of the animation
  • The duration of the animation

Animation Properties

Property	Description
@keyframes	Defines keyframes within CSS animations, specifying intermediate steps and style changes at different points in time.
animation	A shorthand property that combines multiple animation properties into a single declaration, including animation-name, animation-duration, animation-delay, animation-iteration-count, animation-direction, and more.
animation-direction	Specifies the direction of the animation playback, such as forward, backward, alternate, or alternate-reverse.
animation-duration	Sets the length of time for the animation to complete one cycle, specified in seconds (s) or milliseconds (ms).
animation-iteration-count	Determines the number of times the animation should repeat, using a specific number or the keyword "infinite" for infinite repetitions.
animation-timing-function	Defines the timing function for the animation. ease-in-out means the animation starts slow, accelerates, and then slows down towards the end.
animation-name	Specifies the name of the @keyframes rule that defines the animation's keyframes, binding the animation to a selector.

• It's important to consider performance implications when working with CSS animations, as complex animations or excessive use of animations can impact page load times and overall performance.

Transform: translateX() Property

• The transform: translateX() property in CSS allows you to move an element horizontally along the X-axis. It is commonly used in CSS animations to create sliding or moving effects.
• Here's an example of how to use transform: translateX() in a CSS animation:

With Transform: translateX()

Blocks	Output

• In this example, we have defined a CSS animation named slide-animation using the @keyframes rule.
• The animation moves the element from its initial position (0) to a translated position of 200px along the X-axis.

Without Transform: translateX()

• An example of without apply transform: translateX() in a CSS animation:

Block	Output

• Without using the transform: translateX() property or a similar transformation, it's not possible to achieve a smooth animation effect of horizontal movement.
• CSS animations primarily rely on properties like transform to create animations.
