html - CSS 背景颜色不缩放 ASP.NET

Question

我有一个带有一些 CSS 作为背景的母版页，并且还使用另一个 div 来围绕我希望放置在页面上的内容提供一个内容框。但是，当我将内容 div 缩放为 1000px 时，背景 div 似乎没有看到我已经将内容 div 扩展到了当前高度之外。有人对此有任何想法吗？我认为这与母版页内容控件有关，但不确定。

我在这里拥有的一些东西是我在玩它。例如，我将内容框硬编码为 100% 的高度，但它不会有，因为我希望内容框根据其内容展开。但是硬编码的高度让我能够展示背景如何与内容不匹配的事实。

这是代码：CSS：

body
{
border: 0px none;
margin: 0px;
padding: 0px;   
}

.Button
{
font-family: Arial, Helvetica, sans-serif;

-moz-border-radius: 10px;

看起来您遇到的问题主要是由样式表中的子元素（ContentBox）和父元素（ContentBackground）都具有绝对定位引起的。

如果您稍微编辑您的 css，它应该可以解决您的问题。

删除height: 100%;和position: absolute;从.ContentBackground

和

position: absolute;从中删除.ContentBox

这里有一篇文章可以帮助你更多地了解定位：http ://www.barelyfitz.com/screencast/html-training/css/positioning/
