CSS Animation Tutorial: Teach you step by step how to implement rotation effects

Introduction:
CSS animation is one of the important components of modern web design. CSS animation can Add interactivity and visual appeal to web pages. This article will teach you how to use CSS to implement a simple and beautiful rotation effect. Through simple code examples, you can easily master this technique.

1. Create HTML structure:
   First, we need to create an HTML structure to accommodate our rotation effect. In the HTML file, add the following code:

<div class="box">
  <div class="content">
    <!-- 在此处添加你的内容 -->
  </div>
</div>

Through the above code, we create a parent container .box and nest a child container ## inside it. #.content. You can add the content you want to display in .content, such as text, pictures, etc.

Add CSS styles:
2. Next, we need to add CSS styles to the HTML structure we just created to achieve rotation effects. In the CSS file, add the following code:
   

.box {
  width: 200px;
  height: 200px;
  position: relative;
  perspective: 1000px;
}

.content {
  width: 100%;
  height: 100%;
  position: absolute;
  top: 0;
  left: 0;
  transform-style: preserve-3d;
  animation: rotate 5s infinite linear;
}

@keyframes rotate {
  0% {
    transform: rotateY(0);
  }
  100% {
    transform: rotateY(1turn);
  }
}

Through the above code, we set the width, height and relative positioning for the parent container

.box. At the same time, we set the width, height, and absolute positioning of .content, and set the transform-style property to preserve-3d to enable the 3D effect.

In

@keyframes, we define an animation named rotate. This animation rotates the element from the initial state to the final state of 360 degrees, which is implemented through the rotateY method of the transform attribute. Apply the animation attribute to .content, and set the animation playback time to 5 seconds, loop playback, and specify a linear animation change method.

View the effect:
3. Open the HTML file in the browser, you will see a rotation effect. The content in
   .content will continue to rotate along the Y axis.
Further improvements:
You can adjust the width and height of
• .box to suit your needs.
If you want to change the direction of rotation, just modify the parameters of
• rotateY.
Adjust the animation playback time and loop mode to obtain different effects.

Through the tutorial in this article, we learned how to use CSS to implement a simple and beautiful rotation effect. By properly adjusting the style, you can create a variety of cool rotation animations. I hope this article will help you understand and use CSS animation!
