🎵 音乐播放器设计与实现

设计思路

我将创建一个响应式音乐播放器,核心功能包括:左右对称旋转的专辑图片、同步的音乐控制、实时进度条显示和歌词滚动效果。旋转效果将通过CSS动画实现,音乐控制则使用HTML5 Audio API,歌词同步通过JavaScript处理

    怎么添加歌曲和歌词呢??

      站长回复参照这个样式添加 src=歌曲 // 示例歌词数据(格式:时间(秒) + 歌词) const lyricsData = [ { time: 0, text: "欢迎使用音乐播放器" }, { time: 5, text: "这是一段示例歌词" }, { time: 10, text: "左右图片正在同步旋转" }, { time: 15, text: "享受音乐的魅力" }, { time: 20, text: "播放器设计精美" }, { time: 25, text: "功能齐全实用" }, { time: 30, text: "感谢使用本播放器" }, { time: 35, text: "更多功能等你发现" } ];
