闹鬼房间是怎么画出来的？
闹鬼房间用 div 拼出一面维多利亚风格的鬼屋墙：三幅肖像画、壁灯蜡烛、落地钟和游荡的小幽灵；时钟指针靠 JavaScript 实时走动，其余氛围全靠 CSS 动画。
说白了就三件事
HTML： .haunted-room里叠画框、烛台、落地钟与幽灵 emoji。CSS：条纹墙纸、画框金边、烛火摇曳、钟摆、幽灵飘动，多层 @keyframes营造阴森光感。JavaScript： updateClock()读取系统时间，平滑驱动时、分、秒针旋转。
改配色动 CSS，改时钟逻辑动 JS，结构保持分层别搅在一起。
颜色为啥长这样
墙纸：#2a1a20 / #251518 竖条纹，底部渐暗 画框：深棕木色 + 金色 #8b6914装饰边烛光：橙黄 #ff9933→#ff6600渐变，外圈暖色光晕钟面：象牙白 #f5f0e8，罗马数字深棕幽灵：emoji 👻，带半透明与飘动轨迹
动起来是啥感觉
整页铺满视口，像站在一间点着蜡烛的暗室里。三幅肖像微微泛光，两侧烛火持续摇曳，落地钟秒针顺滑转动、钟摆左右摆，小幽灵在房间里缓慢漂移并淡入淡出。
烛火 flicker动画随机感摇曳，照亮附近墙面钟摆以底部为轴左右摆动，与钟表古典造型配合 幽灵沿曲线路径漂浮，缩放与透明度同步变化 画框内角色 emoji 可替换，暗角 .portrait-vignette压暗四角
怎么一层层画出来
墙面与灯光
墙纸： repeating-linear-gradient竖纹 + 整体纵向渐暗。壁灯 .sconce：梯形装饰 + 阴影，左右对称摆放。蜡烛 .candle：柱体 +.flame椭圆火焰，多层 box-shadow 模拟光晕。
肖像画
画框 .picture-frame：外框、四角.frame-corner、内线.frame-inner-detail。画布 .portrait-canvas：居中 emoji + 暗角遮罩。
落地钟
顶部 .pediment：三角楣 + 卷草装饰。柱廊 .columns：左右柱身与柱头柱础。表盘 .clock-face：罗马数字定位 + 三根指针与中心 hub。钟摆 .pendulum：杆 + 摆锤，CSS 摆动；JS 只管指针。
幽灵
.ghost：大号 emoji，绝对定位 + 飘动 keyframes。
