父容器 {
/*设置宽高*/ width: 100%; height: 100%; /*下面的属性是必须的*/ position: relative; background: radial-gradient(200% 100% at bottom center, #f7f7b6, #e96f92, #75517d, #1b2947); background: radial-gradient(220% 105% at top center, #1b2947 10%, #75517d 40%, #e96f92 65%, #f7f7b6); background-attachment: fixed; overflow: hidden; }
组件:
<template> <div class="star-bg"> <div v-for="i in stars" :key="i" class="star-bg-star" :style="{ transformOrigin:'0 0 '+(distance+Math.random()*300)+'px', transform:'translate3d(0,0,-'+(distance+Math.random()*300)+'px) rotateY('+(Math.random()*360)+'deg) rotateX('+(Math.random()*-50)+'deg) scale('+(0.2+Math.random())+','+(0.2+Math.random())+')' }"> </div> </div> </template> <script> export default { name: "star-bg", data() { return {} }, methods: {}, props: { stars: { type: Number, default: 1000 }, distance: { type: Number, default: 800 } }, } </script> <style scoped> body { } @keyframes rotate { 0% { transform: perspective(400px) rotateZ(20deg) rotateX(-40deg) rotateY(0); } 100% { transform: perspective(400px) rotateZ(20deg) rotateX(-40deg) rotateY(-360deg); } } .star-bg{ background-color: transparent; transform: perspective(500px); transform-style: preserve-3d; position: absolute; bottom: 0; perspective-origin: 50% 100%; left: 50%; animation: rotate 90s infinite linear; } .star-bg-star { width: 2px; height: 2px; background: #f8f8ee; position: absolute; top: 0; left: 0; transform-origin: 0 0 -300px; transform: translate3d(0, 0, -300px); backface-visibility: hidden; } </style>
使用: 向父容器添加css 然后注册组件,在父容器里使用
