Question

如果你看到任何YouTube视频https://www.youtube.com/watch?v=s8yznE7rkiM，当你重新调整页面尺寸时，视频播放器会根据宽高比而改变，而不仅仅是重新调整大小。这很有用，因为它不显示黑条。我对此的尝试并不那么成功。

<style type="text/css">
#actualvid {
width: 100%    !important;
height: auto   !important;
}
</style>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js"></script>   
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<div id="actualvid">
<div id="ytapiplayer" style="width: 620px; height: 480px;" >
You need Flash player 8+ and JavaScript enabled to view this video.
</div>
<script type="text/javascript">

var params = { allowScriptAccess: "always", allowfullscreen: "true" };
var atts = { id: "myytplayer" };

swfobject.embedSWF("http://www.youtube.com/e/s8yznE7rkiM?enablejsapi=1&playerapiid=ytplayer?rel=0&autoplay=1&rel=0","ytapiplayer", "640", "390", "8", null, null, params, atts);

function onYouTubePlayerReady(playerId) {
ytplayer = document.getElementById("myytplayer");
}
function play(el, videoid) {
  if (ytplayer) {
     ytplayer.loadVideoById(videoid);
  } 

// reset background-color for all divs which has class video
$('.video').css('background-color', '#222222');
$(el).css('background-color', '#3A3A3A');
}

</script>
</div>

我尝试这样做的一种方法是将视频放入div并以这种方式进行：http://css-tricks.com/NetMag/FluidWidthVideo/Article-FluidWidthVideo.php但是，我无法让它工作。有人可以帮忙吗？我喜欢YouTube的方式，但似乎它根据窗口大小重新调整大小。

这是一个只有CSS的解决方案：

.embed-container {
  position: relative;
  padding-bottom: 56.25%; /* 16x9 */
  height: 0;
  overflow: hidden;
  max-width: 100%;
  height: auto;
}
.embed-container iframe {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}

<div class='embed-container'>
  <iframe src='http://www.youtube.com/embed/C0DPdy98e4c' frameborder='0' allowfullscreen></iframe>
</div>
