Why can't I just use div in css? Why do I have to use a id selector?

In the video he just typed

body{ background: orange }

If there is only one div on the page then the result would be the same, the advantage of assigning an id is that you are guaranteed to only select that specific div regardless of how many div elements are on the page.

When writing CSS rules you shouldn't just consider what will be selected on the current page but how the rule might affect the page in the future as well. Since it is common to place multiple div elements on a page it is generally a bad idea to use it as a sole selector for a rule when you actually just want to style a specific div element on the page.
