默认的‘<body>’边距有多宽? [英] How wide is the default `<body>` margin?
问题描述
HTML 为其 标签设置的默认 margin 是多少?我注意到有一些自动边距，但我想知道是否有人知道它是多少(以及它是在 px 还是 % 等中).
What’s the default margin that HTML sets for its <body> tag? I noticed that there’s some automatic margin, but I’m wondering if anyone knows how much it is (and whether it’s in px or %, etc.).
推荐答案
在大多数主流浏览器中，所有边的默认边距都是 8px.它由浏览器提供的 user-agent-stylesheet 以像素为单位定义.
In most major browsers, the default margin is 8px on all sides. It is defined in pixels by the user-agent-stylesheet your browser provides.
某些浏览器允许您创建和使用自己的user-agent-stylesheet，但如果您正在开发网站，我建议您不要更改此设置，因为您的用户很可能不会有一个修改过的样式表，然后会看到与您不同的页面.
Some browsers allow you to create and use your own user-agent-stylesheet, but if you are developing a website, I would recommend staying away from changing this, since your users most likely will not have a modified stylesheet and would then see a different page than you do.
如果你想改变它，你可以这样做:
If you want to change it, you can just do this:
body {
margin: 0px;
padding: 0px;
...
}
但是如果你有一个大项目并且想要更完整，使用normalize.css.它重置了许多默认值以在浏览器之间保持一致.
But if you have a large project and want to be more complete, use normalize.css. It resets a lot of default values to be consistent across browsers.
