默认的 `<body>` 边距有多宽? [英] How wide is the default `<body>` margin?
问题描述
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.).
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.
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.
If you want to change it, you can just do this:
body {
margin: 0px;
padding: 0px;
...
}
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.
