What is the default margin that HTML sets for its tags? I noticed there is some auto margin, but I was wondering if anyone knows what it is (and if it's in px or % etc.).

According to W3School’s CSS reference, The default attributes and values of the body tag are,
body{ display : block; margin : 8px; }
By accessing the Calculation Pane in Chrome Dev Tools.

In most major browsers, the default margins on all sides are 8px. It is defined in pixels by the user-agent-stylesheet provided by the browser.
Some browsers allow you to create and use your own user-agent-stylesheet, but if you are developing a website I recommend not changing this as your users most likely won't Make a modified stylesheet and you'll see a different page than you did.
If you want to change it, you can 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 many default values to be consistent across browsers.
