今天为大家收集了几种不同风格的登录页，搭配动态渐变背景，效果绝对惊艳！

CSS3实现动态渐变+玻璃拟态登录页

一、开篇语

纯CSS实现当下最火的玻璃拟态(Morphism)风格登录页，搭配动态渐变背景，效果绝对惊艳！

二、设计特色

✅ 流动渐变背景
✅ 毛玻璃视觉效果
✅ 动态标签动画
✅ 按钮流光特效

三、关键技术

CSS渐变背景：background: linear-gradient()
背景模糊：backdrop-filter: blur()
形状动画：@keyframes控制渐变运动
边框技巧：利用mask实现内边框

四、完整代码

<!-- 方案二：动态渐变 + 玻璃拟态 -->

</head>
<body><div class="bg-blob"></div><div class="bg-blob" style="right: -200px; bottom: -200px;"></div><div class="login-container"><h2 style="color: white; text-align: center; margin-bottom: 30px;">系统登录</h2><div class="input-box"><input type="text" required><span class="floating-label">用户名</span></div><div class="input-box"><input type="password" required><span class="floating-label">密码</span></div><button class="login-btn">立即登录</button></div>
</body>
</html>

五、实现要点

使用伪元素创建流动背景
巧用CSS滤镜实现磨砂效果
输入框焦点状态控制
按钮悬停动画实现

六、浏览器兼容性

⚠️ 注意：backdrop-filter在Firefox中需要开启实验特性

粒子特效+浮动动画

一、技术亮点

粒子动画系统：使用particles.js实现可交互的粒子背景
玻璃拟态设计：半透明背景+模糊效果
动态输入框：标签浮动动画
悬停交互：卡片悬浮效果
