Read | Write | Execute

Many web developers never really get taught the difference between styling the html element and styling the body element. Browsers papered over that distinction for years, which made it easy to learn the wrong lesson.

But the distinction matters. One is the root of the document. The other is the container for the rendered page content. Once that clicks, a lot of layout weirdness stops feeling mysterious and starts feeling mechanical.

This is the kind of thing Bit by Bit exists for: small technical clarifications that make the craft cleaner.
