The CSS box model is a concept used to control the layout of HTML elements. It treats each element as a rectangular box that consists of content, padding, border, and margin.

How does the content size affect the box model?

The content size is the width and height of the actual text or image. By default, browsers calculate this size based on the content itself, but developers can adjust it using CSS properties such as width, height, min-width, and max-width.
