CSS Animations:

CSS animations allow you to smoothly transition between different states of an element without the need for complex JavaScript code. SEM Company Here's a simple example of how you can create a CSS animation:

css

Copy code

@keyframes slide-in {

  from {

    transform: translateX(-100%);

  }

  to {

    transform: translateX(0);

  }

}

.element {

  width: 100px;

  height: 100px;

  background-color: blue;

  animation: slide-in 1s ease-in-out;

}

}

.element:hover {

  width: 150px;

}

JavaScript Animation:

While CSS animations and transitions are powerful, JavaScript allows for more complex and interactive animations. Web Development agency  You can use JavaScript libraries like GreenSock Animation Platform (GSAP) to create sophisticated animations. Here's a basic example using GSAP:

javascript

const element = document.querySelector('.element');

gsap.to(element, {

  duration: 1,

  x: 200,

  rotation: 360,

  ease: 'power2.out',

});

In this example, the GSAP library is used to animate an element's position and rotation. The animation will take 1 second, move the element 200 pixels to the right, and rotate it 360 degrees with a specified easing function.
