Is there any comprehensive documentation on tag attributes for this HTML?

For example, body tag

You can set the pixels of the margin like this.
So are there ready-made attributes about tags?

For example, I clicked on the body tag, and then a series of settable attributes about the body tag were displayed next to it



Is there such a document?
If yes, please provide a download address.

The poster can look at the html tag list, and clicking on each tag will list more detailed information.

Such definitions are basically abandoned. css to write
body {
margin: 60px 0 0 40px;
}
