Introduction
CSS Keyframes Animation allows you to create smooth and controlled animations by defining stages of movement or style changes. It is useful for making websites more interactive and visually appealing without using JavaScript.<\/p>\n\n\n\n
What is Keyframes Animation
Keyframes define how an element changes style at different points during an animation. You can control properties such as position, color, size, opacity, and more.<\/p>\n\n\n\n
Basic Syntax
To create a keyframe animation, you define the animation using the at keyframes rule and then apply it to an element.<\/p>\n\n\n\n
Example
At keyframes exampleAnimation
From
transform translateX zero
To
transform translateX 200px<\/p>\n\n\n\n
Then apply it to an element<\/p>\n\n\n\n
div
animation name exampleAnimation
animation duration 2s<\/p>\n\n\n\n
How Keyframes Work
Animations are divided into stages using percentages. Each percentage represents a point during the animation timeline.<\/p>\n\n\n\n
Example with percentages
At keyframes moveBox
0 percent
left 0px
50 percent
left 100px
100 percent
left 200px<\/p>\n\n\n\n
