使用 width 属性
如果 width 属性设置为 100%,视频播放器会根据屏幕大小自动调整比例:
实例
<!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta charset="utf-8"> <title>php 中文网</title> <style> video { width: 100%; height: auto; } </style> </head> <body> <video width="400" controls> <source src="http://globalvideo.php.cn/xphp/11-10-3.mp4" type="video/mp4"> <source src="" type="video/ogg"> 您的浏览器不支持HTML5视频。 </video> <p>调整浏览器窗口大小查看视频播放器变化</p> </body> </html>

注意在以上实例中,视频播放器根据屏幕大小自动调整比例,且可以比原始尺寸大。更多情况下我们可以使用 max-width 属性来替代。
使用 max-width 属性
如果 max-width 属性设置为 100%, 视频播放器会根据屏幕自动调整比例,但不会超过其原始大小:
实例
<!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta charset="utf-8"> <title>php 中文网</title> <style> video { max-width: 100%; height: auto; } </style> </head> <body> <video width="400" controls> <source src="http://globalvideo.php.cn/xphp/11-10-3.mp4" type="video/mp4"> <source src="" type="video/ogg"> 您的浏览器不支持HTML5视频。 </video> <p>调整浏览器窗口大小,在宽度小于 400px 时,查看视频播放器的变化。</p> </body> </html>

在网页中添加视频
我们可以在网页中添加视频。以下实例视频根据 div 区域大小自动调整并占满整个 div 区域:
实例
<!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta charset="utf-8"> <title>php 中文网</title> <style> * { box-sizing: border-box; } video { width: 100%; height: auto; } .row:after { content: ""; clear: both; display: block; } [class*="col-"] { float: left; padding: 15px; width: 100%; } @media only screen and (min-width: 600px) { .col-s-12 {width: 8.33%;} .col-s-2 {width: 16.66%;} .col-s-3 {width: 25%;} .col-s-4 {width: 33.33%;} .col-s-5 {width: 41.66%;} .col-s-6 {width: 50%;} .col-s-7 {width: 58.33%;} .col-s-8 {width: 66.66%;} .col-s-9 {width: 75%;} .col-s-10 {width: 83.33%;} .col-s-11 {width: 91.66%;} .col-s-12 {width: 100%;} } @media only screen and (min-width: 768px) { .col-1 {width: 8.33%;} .col-2 {width: 16.66%;} .col-3 {width: 25%;} .col-4 {width: 33.33%;} .col-5 {width: 41.66%;} .col-6 {width: 50%;} .col-7 {width: 58.33%;} .col-8 {width: 66.66%;} .col-9 {width: 75%;} .col-10 {width: 83.33%;} .col-11 {width: 91.66%;} .col-12 {width: 100%;} } html { font-family: "Lucida Sans", sans-serif; } .header { background-color: #9933cc; color: #ffffff; padding: 15px; } .menu ul { list-style-type: none; margin: 0; padding: 0; } .menu li { padding: 8px; margin-bottom: 7px; background-color :#33b5e5; color: #ffffff; box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24); } .menu li:hover { background-color: #0099cc; } .aside { background-color: #33b5e5; padding: 15px; color: #ffffff; text-align: center; font-size: 14px; box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24); } .footer { background-color: #0099cc; color: #ffffff; text-align: center; font-size: 12px; padding: 15px; } </style> </head> <body> <h1>复制代码,在浏览器上运行,查看效果!</h1> <div class="header"> <h1>Chania</h1> </div> <div class="row"> <div class="col-3 col-s-3 menu"> <ul> <li>The Flight</li> <li>The City</li> <li>The Island</li> <li>The Food</li> </ul> </div> <div class="col-6 col-s-9"> <h1>The City</h1> <p>php中文网--弹性盒子布局flex</p> <video width="400" controls> <source src="http://globalvideo.php.cn/xphp/11-10-3.mp4" type="video/mp4"> <source src="" type="video/ogg"> 您的浏览器不支持HTML5视频。 </video> </div> <div class="col-3 col-s-12"> <div class="aside"> <h2>What?</h2> <p>Chania is a city on the island of Crete.</p> <h2>Where?</h2> <p>Crete is a Greek island in the Mediterranean Sea.</p> <h2>How?</h2> <p>You can reach Chania airport from all over Europe.</p> </div> </div> </div> <div class="footer"> <p>Resize the browser window to see how the content respond to the resizing.</p> </div> </body> </html>
