This article brings you examples of css3D animation (complete code attached), which has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
Preface
I recently played around with using CSS to create 3D effects and wrote several demos, so I will summarize them in this blog. Before reading this blog, please first understand the properties of css 3D, such as: transform-style, transform-origin, transform, perspective.
Write a simple cube
1. We first use css to implement a cuboid. A cuboid has 6 sides. We write 6 li and wrap it with an ul. According to My experience in writing 3D animation is that it is best to have a parent element to wrap
<p> </p>
2. First set the width and height for .parent, and set the viewing distance and base point position for it.
.parent{
width: 800px;
height: 400px;
border: 1px solid #000;
margin: 0 auto;
perspective: 2000px;
perspective-origin: -40% -80%;
background: #000;
}3. Set the width, height and preserve-3d attributes of ul to retain the 3D transformation of the sub-element. All sub-elements li are absolutely positioned
ul{
width: 50px;
position: relative;
margin: 100px auto;
transform-style : preserve-3d;
}
li{
width: 100px;
height: 100px;
background: rgba(255, 255, 0, 0.3);
position: absolute;
text-align: center;
border: 3px solid greenyellow;
}The effect is as shown below As shown:
4. First write a face and set background for its background: rgba(255, 255, 0, 0.3 );
li:nth-child(1){
background: rgba(255, 255, 0, 0.3);
transform: translateY(50px) rotateX(90deg);
}The effect is as shown below:
5. We have written the first face, and then we adjust the other 6 faces to become as shown in the picture below. The rotation direction of rotate will not be explained here. Friends who do not understand can check other documents by themselves.
/*上面*/
li:nth-child(1){
transform: translateY(-50px) rotateX(90deg);
}
/*下面*/
li:nth-child(2){
transform: translateY(50px) rotateX(90deg);
}
/*左面*/
li:nth-child(3){
transform: translateX(-50px) rotateY(90deg);
}
/*右面*/
li:nth-child(4){
transform: translateX(50px) rotateY(90deg);
}
/*前面*/
li:nth-child(5){
transform: translateZ(50px);
}
/*后面*/
li:nth-child(6){
transform: translateZ(-50px);
}The effect is as shown below:
1. The code is as follows:

perspective-origin: 10% 20%;
}
.cube{
width: 200px;
height: 300px;
transform-style: preserve-3d;
margin:100px auto;
position: relative;
transform: rotateX(30deg);
border-radius: 50%;
padding: 60px;
}
.mian{
width: 200px;
height: 300px;
background-image: url(1.jpg);
background-position:400px 0;
position: absolute;
border: 1px solid #ccc;
transition: 2s;
}
/* .mian1:hover{
transform-origin: right;
transform: rotateY(-60deg);
} */
.mian1{
transform-origin: right;
transform: translateX(-200px) rotateY(45deg);
background-position: 0 0;
}
.mian3{
transform-origin: left;
transform: translateX(200px) rotateY(45deg);
background-position: 200px 0;
}
.mian3:hover{
transform: translateX(200px) rotateY(0deg);
}
.mian1:hover{
transform: translateX(-200px) rotateY(0deg);
}
