Question

我想在我的页面中使用一个不占用整个屏幕的div，当它的内容溢出时使用屏幕边缘的滚动条。我知道这听起来令人困惑，所以这里有一个例子：http://www.csszengarden.com/?cssfile=/202/202.css&page=1

我会发布代码，但我不知道从哪里开始。有人可以用HTML＆amp; CSS？

Answer 1

一个技巧是覆盖一个或多个静态图像或框并修复它们的位置，然后调整整个页面的可滚动区域，内部<div>，使其宽度适合暴露在“可视区域” （即未覆盖）由您的覆盖区域（您可以使用填充来实现此目的）。

我做了demo page来说明这一点。根据我的建议，它确实涉及额外的标记;我打赌用CSS Zen Garden提供的相同基本标记来使用更复杂的CSS来实现相同的效果，但我的答案只是另一种更简单的方法。

源代码如下。该代码段是可运行的，但由于尺寸未经原始尺寸修改，因此您需要全屏查看尺寸以查看有效的内容。

body {
    margin: 0;
}

h1 {
    text-align: center;
}

#overlay div {
    position: fixed;
    width: 100%;
    height: 100%;
    background-color: gray;
}

/* The top and bottom "borders". */
#overlay .vert {
    height: 150px;
}

/* The left and right "borders". */
#overlay .hor {
    width: 300px;
}

/* Anchor the parts of your overlay boxes to the respective edges of the page. */
#overlay-top { top: 0; }
#overlay-bottom { bottom: 0; }
#overlay-left { left: 0; }
#overlay-right { right: 0; }

/* Your content has padding equal to the sizes of your overlay "borders". */
#content {
    padding: 150px 300px;
}

<!-- This acts as the overlay, or mask, of your content. -->
<div id="overlay">
    <div id="overlay-top" class="vert"></div>
    <div id="overlay-bottom" class="vert"></div>
    <div id="overlay-left" class="hor"></div>
    <div id="overlay-right" class="hor"></div>
</div>

<!-- The entire content of your page would go here. -->
<div id="content">
    <h1>Top of content</h1>

当div的周围环境始终固定时，BoltClock的答案很好，但是当你想要使用div（就像一个模态对话框）时，你想要使用页面的滚动条，它就无法使用。< / p>

对于这种情况，您可以通过将此样式应用于正文来禁用和隐藏页面滚动条：

body {overflow:hidden}

给定的div必须填满整个页面并有滚动条：

div {position:fixed; top:0; left:0; width:100%; height:100%; overflow-y:scroll}

现在div滚动条正好出现在页面滚动条的位置，它的内容可以滚动。

当div关闭时，必须重置主体溢出样式。
