html - IE z-index 问题与 iframe

Question

我有一个 Youtube 视频 iframe 覆盖整个窗口(100% 宽度和高度)，我让其余元素在视频上滚动。 在 Chrome 和 Firefox 上一切正常，但 IE 似乎没有响应 z-index。

我在这里创建了一个 jsFiddle http://jsfiddle.net/RickyStam/42tLS/您可以在哪里看到问题。

HTML

    <div class="page-container">
        <div>
            <div class="header">
                <a href="/index.aspx"><img src="Images/logo.png" /></a>
                <div class="menu-container">
                    <ul>
                        <li><a href="#">solutions</a></li>
                        <li><a href="#">about us</a></li>
                        <li><a href="#">contact</a></li>
                    </ul>
                </div>
                <div class="clear"></div>
            </div>
            <div class="video-container">
                <iframe class="video-player" src="//www.youtube.com/embed/7x8BCbo45qA?autoplay=0&showinfo=0&controls=0" wmode="Opaque" frameborder="0" allowfullscreen></iframe>
                <div class="video-container-text">

                </div>
            </div>
        </div>
        <div style="width: 100%; height: 685px; z-index: 12"></div>
        <div class="aboutus-container">
            <h1>ABOUT US</h1>

        </div>
    </div>

任何帮助将不胜感激!

我设法找到我必须添加到 iframe &wmode=opaque

src 的答案

这是完整的 iframe:

<iframe class="video-player" src="//www.youtube.com/embed/7x8BCbo45qA?autoplay=0&showinfo=0&controls=0&wmode=opaque" wmode="Opaque" frameborder="0" allowfullscreen></iframe>
