> These are things that you learn in a first week of doing web development tutorials. You meant CSS tutorials? Never read about "margins collapse" in web development tutorials. Web development tutorials I read (like 10 years ago) were usually about having a web server renders some data queried from a database into some basic HTML. And adding a form to create/edit rows in the database. Then perhaps adding some basic style like colors and paddings and some jQuery to validate the form. Finally moving that page from localhost to internet. Let's be honest, web development covers a very large area of knowledge and CSS is not the most interesting part (not saying CSS is not interesting!). I guess most people just skip the CSS documentation and learn it by inspecting other pages and copying rules, and searching "how to do X in CSS" and reading tutorials about their specific question.
