# CSS怎么制作超萌吃豆豆加载动画效果  *图:最终实现的吃豆豆加载效果* ## 一、前言:为什么选择吃豆豆动画 在网页设计中,加载动画是改善用户体验的重要元素。经典的吃豆人(Pac-Man)游戏形象具有以下优势: - 高辨识度的怀旧元素 - 简单的几何形状易于CSS实现 - 动态效果能直观表达"加载中"的状态 本文将分步骤教你用纯CSS实现这个动画,包含: 1. 吃豆人主体造型 2. 豆子的绘制与运动轨迹 3. 嘴巴开合动画 4. 整体协调控制 ## 二、HTML基础结构搭建 ```html <div class="pacman-loading"> <div class="pacman"></div> <div class="dots"> <span></span> <span></span> <span></span> <span></span> </div> </div>
结构说明: - 外层容器.pacman-loading
控制整体定位 - .pacman
是吃豆人主体 - .dots
包含多个<span>
作为豆子元素
.pacman { width: 100px; height: 100px; border-radius: 50%; background: #FFD700; position: relative; margin-top: 20px; } /* 嘴巴开合效果 */ .pacman::before { content: ""; position: absolute; width: 100%; height: 100%; background: #000; border-radius: 50%; clip-path: polygon(100% 50%, 50% 0, 50% 100%); animation: eat 0.7s linear infinite; } @keyframes eat { 0% { clip-path: polygon(100% 50%, 50% 0, 50% 100%); } 25% { clip-path: polygon(100% 50%, 70% 20%, 70% 80%); } 50% { clip-path: polygon(100% 50%, 100% 30%, 100% 70%); } 75% { clip-path: polygon(100% 50%, 70% 20%, 70% 80%); } 100% { clip-path: polygon(100% 50%, 50% 0, 50% 100%); } }
关键技术点: - clip-path
实现嘴巴切割效果 - 关键帧动画控制嘴巴张合节奏 - 黄金色(#FFD700)还原经典配色
.dots { display: flex; position: absolute; top: 50px; left: 120px; gap: 20px; } .dots span { display: block; width: 20px; height: 20px; border-radius: 50%; background: #FFF; opacity: 0; animation: move 3s linear infinite; } .dots span:nth-child(1) { animation-delay: 0s; } .dots span:nth-child(2) { animation-delay: 0.3s; } .dots span:nth-child(3) { animation-delay: 0.6s; } .dots span:nth-child(4) { animation-delay: 0.9s; } @keyframes move { 0% { transform: translateX(0); opacity: 0; } 10% { opacity: 1; } 90% { opacity: 1; } 100% { transform: translateX(-150px); opacity: 0; } }
动画原理: - 多个豆子错开时间延迟(animation-delay) - 透明度变化实现渐现渐隐 - 水平位移模拟被吃掉效果
.pacman-loading { width: 300px; height: 150px; margin: 0 auto; position: relative; background: #222; border-radius: 20px; display: flex; justify-content: center; }
@media (max-width: 600px) { .pacman { width: 60px; height: 60px; } .dots span { width: 12px; height: 12px; } .dots { left: 80px; top: 30px; } }
.pacman { box-shadow: 0 0 10px #FF0, inset -5px -5px 5px rgba(0,0,0,0.2); } .dots span { box-shadow: 0 0 5px #FFF; }
.pacman::after { content: ""; position: absolute; width: 15px; height: 15px; background: #000; border-radius: 50%; top: 20px; right: 30px; }

场景化设计:
交互增强:
document.querySelector('.pacman-loading') .addEventListener('click', () => { alert('Loading...'); });
性能优化:
