Is the css in the head or the body?

CSS can be written in the head and body.

Written in the head can be used by the entire body, but written in the body may only be used by a certain DIV. It depends on how to use it. There's nothing inherently wrong with it. In terms of tidiness, the head is certainly better.

When discussing web standards, something that always comes up is the importance of separating structure and presentation. The separation of structure and presentation can bring us many benefits, such as style reuse, unified standards, etc. The first thing to separate the structure and tags is to extract all the statements that set the element style separately into a css file.

Therefore, it is more recommended to write the style sheet in a separate file and call it in the head to control the performance of the entire page.
