效果介绍

液态玻璃（Liquid Glass）是一种极具现代感的UI视觉风格，常见于高端网站和操作系统界面。它通过多层叠加、模糊、光泽、滤镜等技术，模拟出玻璃的通透、折射和高光质感。苹果的这次系统设计更新，带火了这一设计效果，本教程将带你一步步实现一个带有3D灵动倾斜交互的液态玻璃登录卡片。

实际效果：

Vue实现一个“液态玻璃”效果登录卡片_3D

技术原理解析

1. 多层叠加

液态玻璃效果的核心是多层视觉叠加：

2. 3D灵动倾斜

通过监听鼠标在卡片上的移动，动态计算并设置 transform: perspective(...) rotateX(...) rotateY(...)，让卡片随鼠标灵动倾斜，增强交互体验。

3. 背景与环境

背景可以是渐变色，也可以是图片。玻璃卡片通过 backdrop-filter 与背景内容产生交互，形成真实的玻璃质感。

实现步骤详解

1. 结构搭建

<template>
  <div class="login-container animated-background">
    <!-- SVG滤镜库 -->
    <svg style="display: none">...</svg>
    <!-- 登录卡片 -->
    <div
      class="glass-component login-card"
      ref="tiltCard"
      @mousemove="handleMouseMove"
      @mouseleave="handleMouseLeave"
    >
      <div class="glass-effect"></div>
      <div class="glass-tint"></div>
      <div class="glass-shine"></div>
      <div class="glass-content">
        <!-- 登录表单内容 -->
      </div>
    </div>
  </div>
</template>

2. SVG滤镜实现液态扭曲

<svg style="display: none">
  <filter id="glass-distortion" x="0%" y="0%" width="100%" height="100%" filterUnits="objectBoundingBox">
    <feTurbulence type="fractalNoise" baseFrequency="0.001 0.005" numOctaves="1" seed="17" result="turbulence" />
    <feComponentTransfer in="turbulence" result="mapped">
      <feFuncR type="gamma" amplitude="1" exponent="10" offset="0.5" />
      <feFuncG type="gamma" amplitude="0" exponent="1" offset="0" />
      <feFuncB type="gamma" amplitude="0" exponent="1" offset="0.5" />
    </feComponentTransfer>
    <feGaussianBlur in="turbulence" stdDeviation="3" result="softMap" />
    <feSpecularLighting in="softMap" aceScale="5" specularConstant="1" specularExponent="100" lighting-color="white" result="specLight">
      <fePointLight x="-200" y="-200" z="300" />
    </feSpecularLighting>
    <feComposite in="specLight" operator="arithmetic" k1="0" k2="1" k3="1" k4="0" result="litImage" />
    <feDisplacementMap in="SourceGraphic" in2="softMap" scale="200" xChannelSelector="R" yChannelSelector="G" />
  </filter>
</svg>

3. 背景设置

.animated-background {
  width: 100vw;
  height: 100vh;
  background-image: url('你的背景图片路径');
  background-size: cover;
  background-position: center;
  background-repeat: no-repeat;
  position: fixed;
  top: 0;
  left: 0;
  z-index: -1;
}

4. 卡片多层玻璃结构

.login-card {
  width: 400px;
  border-radius: 24px;
  overflow: hidden;
  box-shadow: 0 4px 24px 0 rgba(0,0,0,0.10), 0 1.5px 6px 0 rgba(0,0,0,0.08);
  background: transparent;
  position: relative;
}
.glass-effect {
  position: absolute;
  inset: 0;
  z-index: 0;
  backdrop-filter: blur(5px);
  filter: url(#glass-distortion);
  isolation: isolate;
  border-radius: 24px;
}
.glass-tint {
  position: absolute;
  inset: 0;
  z-index: 1;
  background: rgba(0, 0, 0, 0.15);
  border-radius: 24px;
}
.glass-shine {
  position: absolute;
  inset: 0;
  z-index: 2;
  border: 1px solid rgba(255, 255, 255, 0.13);
  border-radius: 24px;
  box-shadow:
    inset 1px 1px 8px 0 rgba(255, 255, 255, 0.18),
    inset -1px -1px 8px 0 rgba(255, 255, 255, 0.08);
  pointer-events: none;
}
.glass-content {
  position: relative;
  z-index: 3;
  padding: 2rem;
  color: white;
}

5. 3D灵动倾斜交互

methods: {
  handleMouseMove (e) {
    const card = this.$refs.tiltCard
    const rect = card.getBoundingClientRect()
    const x = e.clientX - rect.left
    const y = e.clientY - rect.top
    const centerX = rect.width / 2
    const centerY = rect.height / 2
    const maxTilt = 18
    const rotateY = ((x - centerX) / centerX) * maxTilt
    const rotateX = -((y - centerY) / centerY) * maxTilt
    card.style.transform = `perspective(600px) rotateX(${rotateX}deg) rotateY(${rotateY}deg) scale(1.03)`
  },
  handleMouseLeave () {
    const card = this.$refs.tiltCard
    card.style.transform = 'perspective(600px) rotateX(0deg) rotateY(0deg) scale(1)'
  }
}
