Impact of Padding in the CSS Box Model
Padding adds space between the content of an element and its border. Increasing padding increases the total size of the element because padding is included inside the element's box according to the standard box model (unless using box-sizing: border-box, which includes padding within the specified width and height).
Increases the space between content and border.
Increases the overall size of the element (in standard box model).
Does not affect margin space between elements.
Can be included in width/height if box-sizing: border-box is used.
