How to achieve the burning and flame effects of pictures in Vue?

In modern web development, in order to improve user experience, we often use various animation effects. Among them, the burning and flame effects of pictures are a relatively cool animation effect, which can bring more vivid and attractive visual effects to the website.

As a popular front-end framework, Vue provides rich functions and flexible scalability, and can easily achieve various animation effects. In this article, we will introduce how to use Vue to achieve the burning and flame effects of images.

First, we need to prepare a picture to be animated. You can choose a picture of a burning flame as an example. Next, we need to introduce Vue and related animation libraries.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Vue图片燃烧和火焰效果</title>
</head>
<body>
  <div id="app">
    <img  src="./burning_flame.jpg" :class="{'burning': isBurning}" alt="How to achieve the burning and flame effects of images in Vue?" >
  </div>

  <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>

  <script>
    // 在Vue中创建一个组件
    @Component
    export default class BurningFlame extends Vue {
      // 初始化数据
      isBurning: boolean = false;

      // 添加燃烧动画效果
      startBurning() {
        this.isBurning = true;
      }
    }

    // 创建Vue实例
    new Vue({
      el: '#app',
      components: {
        BurningFlame
      },
      template: '<BurningFlame />'
    });
  </script>
</body>
</html>

In the above code, we first introduced Vue and related animation libraries. Then, we created a component named BurningFlame through the @Component decorator provided by Vue. A variable named isBurning is defined in the component to control whether to display the burning animation effect.

Next, we created a Vue instance through Vue's new Vue() and registered the BurningFlame component to the instance. Finally, we mounted the Vue instance to the app element of the page.

Now, we can control the animation effect of the picture through the isBurning variable in the component. When the value of isBurning is true, the picture will display the burning animation effect.

In order to trigger the burning animation effect, we can call the startBurning method in the Vue instance. This method can be called in a button click event, or automatically after the page is loaded.

Next, we need to use CSS to achieve the burning and flame effects. We can do this by defining a CSS class called burning.

.burning {
  animation: burning 0.5s infinite alternate;
}

@keyframes burning {
  from {
    opacity: 0.5;
    transform: scale(1);
  }
  to {
    opacity: 1;
    transform: scale(1.2);
  }
}

In the above CSS code, we define a CSS class named burning and use the animation attribute to specify the animation effect. Among them, animation: burning 0.5s alternate infinite; means that the animation name is burning, the duration is 0.5 seconds, it plays in an infinite loop, and it plays in reverse after each playback is completed.

@keyframes burning defines the key frames of the animation. from represents the state at the beginning of the animation, and to represents the state at the end of the animation. In this example, we change the transparency by changing the opacity attribute, and change the size by changing the transform attribute.

Finally, we use the <img alt="How to achieve the burning and flame effects of images in Vue?" > tag to display the image to be animated. Through Vue's :class directive, you can dynamically add the burning class based on the value of isBurning.

Through the above code and CSS, we have achieved the burning and flame effects of the image. Just change the value of isBurning to control the animation effect of the picture.

Summary:

In this article, we introduced how to use Vue to achieve the burning and flame effects of images. By defining a CSS class named burning, and controlling whether to display the class through variables in the Vue instance, we can achieve the animation effect of the image. This method is not only simple and easy to use, but also can flexibly expand and adjust animation effects according to actual needs. I believe that by studying this article, you have mastered the method of realizing the burning and flame effects of images in Vue, and you can apply and display it in your own projects.
