How to use css3 to achieve image flipping effects

CSS3 is an integral part of web design. Among them, through the 3D conversion of CSS3, the flipping effect of pictures can be achieved, adding dynamics and fashion to the web page. Let’s take a look at how to implement CSS3 image flipping effects.

Implementation steps

1. First, you need to insert image elements through HTML code, as shown below:

<div class="container">
    <img src="image.jpg" alt="image" />
</div>

where container is the container used to contain images.

2. Next, set the style for container and img through CSS code, as shown below:

.container {
    perspective: 800px;
    /* 把container容器设置成3D透视 */
}
img {
    width: 100%;
    height: 100%;
    /* 设置图片的宽高 */
    position: absolute;
    backface-visibility: hidden;
    /* 隐藏图片的背面 */
    transition: transform .6s ease;
    /* 设置动画效果 */
}

Among them, the perspective attribute is to set the perspective distance of the container, and the backface-visibility attribute is to use To control whether to display the back of the element, and the transition attribute is used to achieve the animation effect of image flipping.

3. Then, set the flip effect for the picture. Set styles for the front and back respectively, as shown below:

img {
    transform-style: preserve-3d;
    /* 设置为3D */
}
img:hover {
    transform: rotateY(180deg);
    /* 翻转180度 */
}
img:after {
    content: '';
    position: absolute;
    width: 100%;
    height: 100%;
    top: 0;
    left: 0;
    backface-visibility: hidden;
    transform: rotateY(180deg);
    /* 翻转180度 */
}
img:hover:after {
    transform: rotateY(0deg);
    /* 返回原来的状态 */
}

Here the transform attribute is used to set the flip angle, and the content attribute is used to add a virtual "pseudo element" behind the element to enhance the style. flexibility.

4. Finally, set the container to perspective and set the flip effect for the image, as shown below:

.container:hover img {
    transform: rotateY(180deg);
    /* 翻转180度 */
}
.container:hover img:after {
    transform: rotateY(0deg);
    /* 返回原来的状态 */
}

In this way, when the mouse is hovering over the container, the image will Flip in 3D.
