CSS Animation Tutorial: Teach you step-by-step to implement the special effect of ball throwing

Introduction:
In modern Web design, CSS animation has become an indispensable element . It can add liveliness and interest to web pages and improve user experience. This tutorial will teach you how to use CSS to achieve a ball throwing effect. Through step-by-step demonstration, you can easily master this technique.

Step 1: Create HTML Structure

First, we need to create an HTML structure to hold our sphere. In the HTML file, add the following code:

<div class="container">
  <div class="ball"></div>
</div>

In this structure, the sphere is placed in a container called "container".

Step 2: Add CSS Styles

Now, we need to add styles to these HTML elements. Open the CSS file and add the following code:

.container {
  width: 500px;
  height: 500px;
  position: relative;
}

.ball {
  width: 50px;
  height: 50px;
  background-color: red;
  border-radius: 50%;
  position: absolute;
  top: 0;
  left: 0;
}

Here, we set the width and height of the container and position it relative. The sphere is set to absolute positioning and placed in the upper left corner of the container.

Step 3: Create CSS Animation

Now, we are going to create an animation effect for the sphere. Add the following code in the CSS file:

@keyframes throw {
  0% {
    top: 0;
    left: 0;
  }
  50% {
    top: 200px;
    left: 300px;
  }
  100% {
    top: 0;
    left: 0;
  }
}

.ball {
  animation-name: throw;
  animation-duration: 2s;
  animation-iteration-count: infinite;
}

In this code, we define a keyframe animation named "throw". At the 0% keyframe, the sphere's position is the initial position (top: 0; left: 0;). At the 50% keyframe, the sphere's position is set to the highest point of the throwing action (top: 200px; left: 300px;). Finally, at the 100% keyframe, the sphere returns to its initial position.

We apply this animation to the sphere and set the duration of the animation to 2 seconds and repeat it infinite times (animation-iteration-count: infinite;).

Step 4: Preview the effect

Save and load your HTML file, and preview the web page. You'll see the ball being thrown along the preset animated path and returning to its original position at the end. Adjusting the parameters in CSS can allow the ball to be thrown in other ways, or change the speed and number of throws.

Summary:
Through this tutorial, you have successfully used CSS to implement the sphere throwing effect. CSS animation is a very useful and interesting tool in web design. Mastering this technique will help you create more engaging and interactive web pages. Now, you can use this method to create other interesting animation effects and continue to explore more possibilities of CSS animation. I hope you can create more amazing works!
