I have searched for an answer but couldn't find it anywhere. My question is reasonably simple: I have a background color of my body, then a large margin, and now I want a different background color inside the margin.
我已经找到了答案,但无法在任何地方找到它。我的问题相当简单:我有一个背景颜色的身体,然后是一个很大的边缘,现在我想在边缘内有不同的背景颜色。
How do I do that with CSS?

If your margin is set on the body, then setting the background color of the html tag should color the margin area
如果在主体上设置了边距,则设置html标签的背景颜色应该为边距区域着色
html { background-color: black; }
body { margin:50px; background-color: white; }

Or as dmackerman suggestions, set a margin of 0, but a border of the size you want the margin to be and set the border-color
或者作为dmackerman的建议,设置一个0的边距,但是你想要边距大小的边框并设置边框颜色

Instead of using a margin, could you use a border? You should do this with <div>
, anyway.
你可以使用边框而不是使用边距吗?无论如何,您应该使用
Something like this?

I needed something similar, and came up with using the :before (or :after) pseudoclasses:
我需要类似的东西,并想出使用:before(或:after)伪类:
#mydiv {
background-color: #fbb;
margin-top: 100px;
position: relative;
}
#mydiv:before {
content: "";
background-color: #bfb;
top: -100px;
height: 100px;
width: 100%;
position: absolute;
}

That is not possible du to the Box Model. However you could use a workaround with css3's border-image, or border-color in general css.
对于Box模型来说,这是不可能的。但是,您可以使用css3的border-image或一般css中的border-color的变通方法。
However im unsure whether you may have a problem with resetting. Some browsers do set a margin to html as well. See Eric Meyers Reset CSS for more!
但是我不确定您是否可能在重置时遇到问题。有些浏览器也为html设置了边距。请参阅Eric Meyers重置CSS以获取更多信息!
html{margin:0;padding:0;}
