背景图片不填充页面宽度

Question

我意识到这是以多种方式提出并回答的，但是在拍完我的大脑后，我无法弄清楚如何正确使用它。你可以看到背景图片并没有填充整个页面（它在两边都不会缩小约10px）。有什么建议？

添加margin:0;到你的身体标记的CSS。大多数浏览器上的默认值在边距上的默认值高达10px

body { 
    font-size: 16px; 
    line-height: 22px; 
    height: auto; 
    font-weight: 300; 
    font-family: 'Ubuntu', sans-serif; 
    color: #122632; 
    background-color: #afcbdc; 
    margin: 0; 
}
