CSS Animation Guide: Teach you step by step how to create bouncing effects, specific code examples are required

Introduction:
In modern Web development, animation effects have become an important factor in improving users One of the important means to experience and attract attention. As a lightweight animation technology, CSS animation can achieve various cool effects through simple code. This article will provide you with a detailed CSS animation production guide. Through step-by-step teaching methods, it will lead you to create an animation with bouncing effects, so that you can better understand and use CSS animation technology.

Preparation work:
Before we start making animations, we need to prepare some basic working environment. First, we need a text editor, such as Sublime Text, Visual Studio Code, etc. Secondly, a modern browser is required to preview and debug animation effects. It is recommended to use Google Chrome or Mozilla Firefox. Finally, we need some basic knowledge of HTML and CSS. If you already know this knowledge, the next thing you need to do is to open your editor and prepare to write code.

Production process:

  1. Create HTML structure

Add a div element to the document and name the class "box". This div will be the carrier of our animation effects.

<div class="box"></div>
  1. Writing CSS styles

Add styles to the "box" element, set basic attributes such as width, height, background color, etc., and position it to the center of the screen.

.box {
  width: 200px;
  height: 200px;
  background-color: #ff0000;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
}
  1. Add animation keyframes

In CSS, we use the @keyframes rule to define the keyframes of animation. In order to achieve the bouncing effect, we need to define three key frames, namely the start frame, the middle frame and the end frame.

@keyframes bounce {
  0% {
    transform: translateY(0);
  }
  50% {
    transform: translateY(-200px);
  }
  100% {
    transform: translateY(0);
  }
}
  1. Apply animation effects

Add animation attributes to the "box" element and set the animation name, duration, delay time and number of animation plays.

.box {
  animation-name: bounce;
  animation-duration: 1s;
  animation-delay: 0.5s;
  animation-iteration-count: infinite;
}

Now, we have completed the animation. Save the file, open the HTML file with a browser, and you will see a red square box with a bouncing effect.

Summary:
Through the study of this article, we have understood the basic principles of CSS animation, and through a specific example, we have created a bouncing special effect animation step by step. After you master these basics, you can further study and try more complex animation effects, such as rotation, gradient, scaling, etc. I hope that through this article, you can have a deeper understanding of CSS animation and be able to use it in actual projects to improve user experience.
