功能说明

  1. 弹出表单触发:
    · 点击页面中央的"点击弹出表单"按钮
    · 表单以平滑动画效果弹出
  2. 表单关闭方式:
    · 点击右上角的关闭按钮
    · 点击表单外部遮罩层
    · 按ESC键
  3. 表单功能:
    · 包含姓名、邮箱、主题和留言内容字段
    · 所有字段均为必填项
    · 提交前进行基本验证
    · 提交成功后显示提示信息并重置表单
  4. 响应式设计:
    · 适配不同屏幕尺寸
    · 在移动设备上优化布局和交互
  5. 用户体验优化:
    · 平滑的过渡动画
    · 视觉反馈(悬停效果)
    · 防止背景滚动

这个实现使用了现代CSS技术(如flexbox、渐变、阴影和过渡动画)和原生JavaScript,没有依赖任何外部库,代码简洁且易于理解。
