保利卫视的云托管嵌套 wordpress，如何才能实现自适应？

后台给的代码：<script src='//player.polyv.net/script/polyvplayer.min.js'></script>
<div id='plv_03b32d7785c7ff0a41adbc08ec_0'></div>
<script>
var player = polyvObject('#plv_03b32d778ba4a67ff0a41adbc08ec_0').videoPlayer({
'width':'970',
'height':'0',
'vid' : '03b32d778ba4a6d5c7ff0a41adbc08ec_0'
});
</script>

但是浏览器的窗口一缩小，就会溢出来？如何才可以调整为自适应呢？
