如何使这两个元素不重叠或 "collide"？

Question

所以我一直在使用 VideoJS 设置我自己的流媒体页面，我现在想要的只是并排聊天，在这种情况下，一个 Twitch 聊天 iframe。 This is what I have now.

问题出在聊天框下方的视频元素。我希望它在聊天框开始的地方结束，这样它们就可以很好地对齐。如果有人能帮我解决这个问题，我将不胜感激。

由于 Whosebug 迫使我也将代码放入此 post，我想这里是..

HTML:

<head>
  <link href="//vjs.zencdn.net/4.9.0/video-js.css" rel="stylesheet">

</head>
<div id="sidebar-wrapper">
    <iframe frameborder="0" scrolling="no" src="http://twitch.tv/test/chat?popout=" height="100%" width="350">
    </iframe>
        </div>
<div class="wrapper">
  <div class="videocontent">

</video>
<script>
videojs("videostream", {}, function(){
// Player (this) is initialized and ready.
});
videojs('videostream').ready(function() {
  this.hotkeys({
    volumeStep: 0.1,
    seekStep: 5,
    alwaysCaptureHotkeys: true
  });
});
</script>
</div>

        }

Answer 1

您已将视频容器的 width 设置为 100%，因此它占用了其容器（网页）width 的 100%。

您可以使用 calc 函数来获得预期的行为，因为您必须从容器的 width 的 100% 中休息 width 的聊天 (350px) .

#videostream{
    width: calc(100% - 350px) !important;
}
