/* ========================================
   CSS Reset 和基础样式
   IE11 兼容性版本
   ======================================== */

/*
 * IE11 兼容性说明：
 * 1. 使用了 IE11 支持的 Flexbox 语法（-ms-flexbox）
 * 2. Grid 布局提供了 Flexbox fallback
 * 3. backdrop-filter 使用了更深的背景色作为 fallback
 * 4. CSS 渐变文字效果在 IE11 中使用纯色文字
 * 5. object-fit 使用背景图片方式实现
 * 6. 所有现代 CSS 特性都有相应的 IE11 兼容方案
