vue页面,背景色设置后不管用

我用了这几种设置方式

page{  
    background-color: #111111;  
}  

"globalStyle": {  
        "navigationBarTextStyle": "white",  
        "navigationBarBackgroundColor": "#111111",  
        "backgroundColor": "#111111",  
        "pageOrientation": "portrait",  
        "animationType":"pop-in",  
        "app-plus": {  
            "background": "#111111"  
        }  
}  

"path":"pages/art/class_list/styles-list",  
        "style": {  
            "navigationBarBackgroundColor":"#111111",  
            "backgroundColor":"#111111",  
            "backgroundColorTop":"#111111",  
            "backgroundColorBottom":"#111111"  
                 }  
}  

当我的vue页面中内容不满一页时,总是会露出底部的白色
而且当我进入vue页面时,屏幕会闪烁白色
