Question

我无法将MVC页面中的背景图像设置为全屏。我屏幕上的输出如下

不确定问题是什么。我已经在app.css文件中设置了body标签的背景图片。正如您在屏幕截图中看到的那样，图像位于网格后面，仅在顶部可见。屏幕底部有空白区域，

我的css如下

body {
    font-family: Helvetica, sans-serif, sans-serif;
    font-size: 13px;
    border-top: none;
    background-image: url('../Images/iNeed__waterfall_BG.jpg');
    background-repeat: no-repeat;
    background-size: cover;

}
