/* ============ IE10 / IE11：flex 容器上的 min-height 在 IE10/11 不生效 ============ */
/* .content1-list-item 在页面上是 column flex 容器（class 带 d-flex flex-column justify-content-end），
   而这条规则只给了 min-height: 218px、没有显式 height —— IE10/11 下 flex 子项会「当作父级没有高度」计算，
   依赖容器高度的 justify-content: flex-end 就失效（内容本该贴底，IE 里会跑到顶部）。
   这里在 IE 专属块里用显式 height 顶替 min-height（取值与 min-height 一致），恢复贴底效果。
   仅 IE10/11 命中（-ms-high-contrast 为其专有媒体特性），现代浏览器完全不受影响。 */
