<h1></h1>
<p></p>h是标签从h1~h6，没用h7,h8
p是段落
<a href="https://www.educoder.net">Educoder平台</a>href可以指定链接进行跳转
<img src="https://www.educoder.net/attachments/download/207801" alt="小狗走路"/>src是指图片地址，alt是未加载出来的时候显示的文字
<div align="center"><img src="./iTunesArtwork@2x.png" align="bottom" width="50" height="50" alt="50*50 应用图标"><img src="./iTunesArtwork@2x.png" width="100" height="100" alt="100*100 应用图标"><img src="./iTunesArtwork@2x.png" width="200" height="200" alt="200*200 应用图标"></div>div中可以指定align信息，img也可以
提供一段代码
<!DOCTYPE html><head><meta charset="UTF-8" /><title>HTML - 音频</title>
</head><body><h1 align="center">青石巷</h1><br><div align="center"><audio controls="controls" autoplay="autoplay" loop="loop" height="100" width="100"><source src="https://www.educoder.net/api/attachments/171686" type="audio/wav"/><source src="https://www.educoder.net/api/attachments/171685" type="audio/ogg"/><source src="https://data.educoder.net/api/attachments/171679" type="audio/mp3"/><embed width="100" height="100">你的浏览器不支持该音频格式。 Your browser does not support this audio format.</audio></div><br><p align="center" style="color:grey;">HTML5 audio 播放示例</p><p align="center" style="color:grey;"><small>注意：音频控件显示效果在不同浏览器中有些许差别。</small></p>
</body>
其中autoplay是页面加载出来就播放，loop是指播放完了重新播放
wav,ogg,mp3是音频的三种方式可以进行尝试播放如果不能成功就会尝试<embed>
接下来给出播放视频的代码
<!DOCTYPE html><head><meta charset="UTF-8" /><title>HTML - 视频</title>
</head><body> <h1 align="center">扬帆起航</h1><video width="550" control="control" autoplay loop><source src="./video/Sail-Away.mp4" type="video/mp4" /><source src="./video/Sail-Away.ogv" type="video/ogv" /><source src="./video/Sail-Away.webm" type="video/webm"/><object data="./video/Sail-Away.mp4" width="320" height="240"><embed src="./video/Sail-Away.swf" width="320" height="240" />你的浏览器不支持该视频格式。Your browser does not support this video format.</object></video><br><p align="center" style="color:grey;">HTML5 video 播放示例</p><p align="center" style="color:grey;"><small>注意：视频控件显示效果在不同浏览器中有些许差别。</small></p>
</div>
</body>
