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.
