CSS - center everything within the body tag
提问by Ben
I am trying to center everything within the tag on the page without adding another container within it. My situation doesn't allow me to change the markup that is being generated but I am able to edit the CSS. My overall objective is to create css that allows me to use the zoom tag in IE for the print css (to zoom out), but the way it is currently working, this creates a lot of white space on the right side and I'd like to make sure the content is always centered in the middle.
我试图将页面上标记内的所有内容居中，而不在其中添加另一个容器。我的情况不允许我更改正在生成的标记，但我能够编辑 CSS。我的总体目标是创建允许我在 IE 中使用缩放标签打印 css（缩小）的 css，但它目前的工作方式，这会在右侧创建很多空白区域，我会喜欢确保内容始终居中。

If you're ok with giving the body a fixed width, you can center it by giving it a width and a margin of autofor the left and right margins:
如果你可以给主体一个固定的宽度，你可以通过给它一个宽度和auto左边距和右边距的边距来将它居中：
E.g:
例如：
body { width: 960px; margin: 0 auto; }
