How to achieve the projection and floating effects of images in Vue?

Introduction:
In modern web design, adding drop shadow and floating effects to pictures can make the page more vivid and attractive. Vue.js is a popular JavaScript framework that can be used to build interactive single-page applications. This article will introduce how to use Vue.js to achieve shadow and floating effects of images, helping you add more visual appeal to your website.

Achieving the shadow effect:
Adding a shadow effect to a picture is achieved by applying CSS styles to the picture elements. In Vue.js, you can use components to organize and manage code. The following is a simple example showing how to add a drop shadow effect to an image using Vue.js:

<template>
  <div>
    <img  class="image lazy"  src="/static/imghw/default1.png"  data-src="imageSrc"  : / alt="How to implement image projection and floating effects in Vue?" >
  </div>
</template>

<script>
export default {
  data() {
    return {
      imageSrc: 'path/to/your/image.jpg'
    };
  }
};
</script>

<style scoped>
.image {
  box-shadow: 0 0 10px rgba(0, 0, 0, 0.5);
}
</style>

In the above example, we defined a Vue component that contains an <img class="image lazy" src="/static/imghw/default1.png" data-src="imageSrc" alt="How to implement image projection and floating effects in Vue?" ># The ## tag binds the path of the image through the :src attribute. In the style section, we used the box-shadow property of CSS to add a shadow effect to the image. By adjusting the parameters of box-shadow, you can customize the color, size, and blur of the shadow.

Achieve floating effect:

To achieve floating effect for pictures, we can use the animation function of Vue.js. The following is an example showing how to use Vue.js to achieve the floating effect of an image:

<template>
  <div>
    <transition name="image-float" mode="out-in">
      <img  class="image lazy"  src="/static/imghw/default1.png"  data-src="imageSrc"  : :key="imageSrc" / alt="How to implement image projection and floating effects in Vue?" >
    </transition>
  </div>
</template>

<script>
export default {
  data() {
    return {
      imageSrc: 'path/to/your/image.jpg'
    };
  }
};
</script>

<style scoped>
.image-float-enter-active,
.image-float-leave-active {
  transition: transform 0.5s;
}

.image-float-enter {
  transform: translateY(100px);
  opacity: 0;
}

.image-float-leave-to {
  transform: translateY(-100px);
  opacity: 0;
}
</style>

In the above example, we use the transition animation function of Vue.js, in

# A transition effect is defined in the ## tag. Define the behavior of the transition by specifying the name attribute for the transition tag and using the corresponding CSS class. We specified the transition mode as 'out-in' using the mode attribute, which means that when the image changes, the old image is hidden first, and then the new image is displayed. In the style part, we use the

transform

property of CSS to achieve the floating effect of the image. Move the vertical position of the image by setting the value of the translateY attribute, and control the transparency of the image by setting the value of the opacity attribute. By adjusting the values ​​of these properties, you can customize the distance and speed at which the image floats. Summary:

By using the components and animation functions of Vue.js, we can easily add projection and floating effects to images to enhance the visual appeal of the web page. You can adjust the parameters of style and animation according to actual needs to achieve more effects and interactions.
