媒体未设置为自动播放。若需要，仅需在 audio 标签加入 autoplay 属性即可：
<audio id="aud" src="..." loop autoplay></audio> 帖子遥控器是一个单标签。单标签能具备如此丰富的功能，得益于mplayer两个伪元素的加持与JS对CSS的操作能力：荧屏与按钮使用用::before和::after实现，JS通过操控dataset和CSS变量令其动态变化。 #mplayer选择器的伪类 :active 用在这里效果不是特别明显。
在此，:active 伪类给元素设定一个效果，即，当遥控器处于活动中时，旋转 5 度——
#mplayer:active { transform: rotate(5deg); }
啥情况是处于活动之时？比如，点击操作。把点击动作放慢一点，这个旋转效果会明显看到。 欣赏学习老师佳帖！赞！！！{:4_187:} 这是极光吗？这小小的遥控器设计的真妙。 梦油 发表于 2023-3-24 10:26
这是极光吗？这小小的遥控器设计的真妙。

中午好 原来不是自动播放的，进帖子听不到声音还以为是我网的问题呢{:4_173:} 点击播放后，视频也出来了，很漂亮大气的制作。这个遥控器用在帖子里还挺漂亮的呢{:4_199:} 红影 发表于 2023-3-24 12:57

嗯，这是为了测试遥控器。生活中，通过遥控器才能启动什么。 红影 发表于 2023-3-24 12:59

还有这样的说法啊，有意思{:4_170:} 马黑黑 发表于 2023-3-24 13:01

而且还挺实用，一点击各种效果就都出来了{:4_173:} 极地极光，真美，小巧清秀的机体状控制器够打眼。点开了迷幻和惊艳，这设计给力！ 黑黑好棒，遥控器可以控制视频停止和播放 这个也是好玩的，很喜欢的效果{:4_178:} js操控css不懂，就觉得js可控视频，灵动短暂的5度旋归也很有创意，点赞问好！
