CSS float div 在窗口调整大小时重叠。我该如何阻止呢？

Question

我刚刚重做了我的网站 www.chartoonz.com

我创建了一个包装器 div，我在其中放置了一个带有指向我在 vimeo 上的视频的链接的 div。我将这个 div 向左浮动，在它旁边我 float 了一个带有一些关于电影的文本的 div，然后将它向右浮动。列看起来没问题，直到窗口调整大小。然后它们重叠得非常厉害，我不明白为什么。在调整窄窗口大小时，我希望右侧 float 列跳到左侧 float 列下方。

相关的 HTML 如下所示:

<div id="CopyWrapper" >

        <div class = "copyFloatLeft">
        <p><strong>Use Video to Communicate.</strong></p>
        <p><iframe src="//player.vimeo.com/video/90334225" width="500" height="281" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe></p>
        <br />
        </p>
        <br /><br />
    </div>
    <div class = "copyFloatRight">
            <strong>Corporate Communications</strong> 
            <p> Corporate communications can be greatly enhanced through a well presented video. Ideas and concepts are easier to understand when they can be seen clearly and their meaning is made plain. Here, I present some of the work I did over the last few months, helping the Merrill Lynch digital advertising division get their message out.</p>
    </div>

    <br /> 
</div>
<br class="clearFloat" />

控制 CSS 如下所示:

#CopyWrapper{
background: center;
text-align: left;
display: block;
float: left;
width: 65%;
padding-left: 200px;
position: relative;
margin: 0 auto;
clear: both;
overflow: hidden;
}


.copyFloatLeft{
background: center;
width: 45%;
margin:5px;
padding: 15px 15px 5px 15px;
position: relative;
clear: right;
float: left;
display: block;
}



.copyFloatRight{
background: center;
width: 45%;
margin:5px;
padding: 15px 15px 5px 15px;
position: relative;
clear: right;
float: right;
display: block;

}

如有任何帮助，我们将不胜感激。

Answer 1

.copyFloatLeft 和 .copyFloatRight block 应该都向左浮动

对于 iframe，我会做类似的事情:

#CopyWrapper iframe {
    width: 100%;
}
