html - 滚动条可见，无法滚动

Question

我有以下 HTML(此处演示:http://jsfiddle.net/49Phn/)，它有一个 ID 为 tabs 的内部 DIV:

<div data-role="page">
    <div id="header"></div>
    <div id="content">
        <div id="tabs">
            <div id="j1">
                <div class="letter">
                    <p>Section 1</p>
                </div>
            </div>
            <div id="j2">
                <div class="letter">
                    <p>Section 2</p>
                </div>
            </div>
            <div id="j3">
                <div class="letter">
                    <p>Section 3</p>
                </div>
            </div>
            <div id="j4">
                <div class="letter">
                    <p>Section 4</p>
                </div>
            </div>
        </div>
    </div>
    <div id="popup-container">
        <div id="popup">
            <div id="pheader">
                <a id="close-popup"></a>
            </div>
        </div>
    </div>
</div>

以及以下 CSS(抱歉太长了):

我的内容容器包含四个框，如果您缩小窗口高度 - 您会看到它们被隐藏，这是所需的行为。

但是，我需要这个容器 div 来滚动——它显示了滚动条(在 Windows 上)——它看起来围绕着正确的高度，但实际上并没有滚动。有什么想法吗？

它绑定(bind)到屏幕边缘的原因是因为它是一款设计用于在多种屏幕尺寸上运行的移动应用。

修复它。我删除了以下几行:

.hub ui-page, .hub .ui-body-c,
.ui-overlay-c ui-page, .ui-overlay-c .ui-body-c,
.ui-mobile-viewport ui-page, .ui-overlay-c .ui-body-c {
    z-index: -2;
}

并改变了:

.hub #content {
    z-index: -1;
}

收件人:

.hub #content {
    z-index: 1;
}

我不认为它喜欢负 z-indexes，大胆猜测。
