The CSS box model refers to how elements are modeled and their dimensions on an html page in css.

The difference between margin and padding is that margins encompass the entire page and padding encompasses a singular element like a box, section, or list.

The total height and width of an html element is determined by a measurement varying in pixels, inches or centimeters, and the font size. The browser then computes a value to create the correct height and width desired.

The padding: 25px 50px is the top and bottom margins are set to the first value and the right and left margins are set to the second.
