不缩放整个页面正文部分的背景图片

我无法将MVC页面中的背景图片设置为全屏。我的屏幕上的输出是不缩放整个页面正文部分的背景图片

不遵循一定的问题是什么。我已经将body标签的背景图像设置为覆盖app.css文件。正如您在屏幕截图中看到的，图像位于网格后面，只在顶部可见。有一个在屏幕下方空白处，

我的CSS是如下

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; 

}

CSS：

html,body { 
    background: url(images/bg.jpg) no-repeat center center fixed; 
    -webkit-background-size: cover; /* For WebKit*/ 
    -moz-background-size: cover; /* Mozilla*/ 
    -o-background-size: cover;  /* Opera*/ 
    background-size: cover;   /* Generic*/ 
}

或：

background-size: 100% 100%;

我试过了。第一个不被css3喜欢。第二个向我展示的是与屏幕截图 – Tom

相同的内容我注意到的另一件事是，如果我评论index.html中的网格，图像就会消失。通常只有图像是预期的。我不明白发生了什么。 index.html中没有对图像的引用。 – Tom

你是否为html标签设置？ –
