以下是一个使用HTML5、CSS和JavaScript编写的简单的3D圣诞树的代码示例:
```html
<!DOCTYPE html>
<html>
<head>
<title>3D圣诞树</title>
<style>
body {
background-color: #111;
overflow: hidden;
}
.tree {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
perspective: 800px;
}
.tree .branch {
position: absolute;
width: 20px;
height: 100px;
background-color: #006400;
transform-origin: bottom center;
transform-style: preserve-3d;
animation: swing 2s infinite alternate;
}
.tree .branch:before {
content: "";
position: absolute;
top: 0;
left: 50%;
width: 20px;
height: 100px;
background-color: #006400;
transform-origin: bottom center;
transform: rotateY(60deg);
}
.tree .branch:after {
content: "";
position: absolute;
top: 0;
left: 50%;
width: 20px;
height: 100px;
background-color: #006400;
transform-origin: bottom center;
transform: rotateY(-60deg);
}
.tree .branch:nth-child(1) {
transform: rotateY(0deg) translateZ(100px);
}
.tree .branch:nth-child(2) {
transform: rotateY(60deg) translateZ(100px);
}
.tree .branch:nth-child(3) {
transform: rotateY(120deg) translateZ(100px);
}
.tree .branch:nth-child(4) {
transform: rotateY(180deg) translateZ(100px);
}
.tree .branch:nth-child(5) {
transform: rotateY(240deg) translateZ(100px);
}
.tree .branch:nth-child(6) {
transform: rotateY(300deg) translateZ(100px);
}
@keyframes swing {
0% {
transform: rotateX(0deg);
}
50% {
transform: rotateX(30deg);
}
100% {
transform: rotateX(0deg);
}
}
</style>
</head>
<body>
<div class="tree">
<div class="branch"></div>
<div class="branch"></div>
<div class="branch"></div>
<div class="branch"></div>
<div class="branch"></div>
<div class="branch"></div>
</div>
</body>
</html>
```
这段代码使用CSS的3D转换和动画效果,通过旋转和平移来创建一个简单的3D圣诞树。在HTML文件中,我们使用`<div>`元素来表示树干和树枝,并使用CSS样式来设置它们的外观和动画效果。
