C# 调整窗口大小时网页内容被压缩

我正在开发asp.net web应用程序。 当我水平调整窗口大小时，所有的网页内容都集中在一起，但当我垂直调整窗口大小时，会出现垂直侧滚动

如何在重新调整大小时显示水平滚动

下面是我的.css代码

html {
    background-image: url("../Images/water2.jpg") ;
    -webkit-background-size: cover; /*for webKit*/
    -moz-background-size: cover; /*Mozilla*/

尝试

最小宽度

，如下所示：

body {
    min-width: 1000px;
}

一旦将页面主体调整到1000像素宽以下，这将向浏览器添加水平滚动条

以下是Try

min width
的文档，如下所示：

body {
    min-width: 1000px;
}
