Question 1

How does padding affect the box size?

Accepted Answer

Padding increases the size of the box from the inside. If you add padding to an element, the total size increases by the amount of padding. For example, if an element has 20px padding, its content area becomes larger by 20px on each side.

Question 2

How does the Box Model affect the size of an element?

Accepted Answer

The size of an element is determined by its width and height plus the padding, border, and margin. For example, if you set an element’s width to 100px, and it has 10px padding, 5px border, and 15px margin, the total width will be 100px (content) + 20px (padding of two sides) + 10px (border of two sides) + 30px (margin of two sides) = 160px.

Question 3

What role does the margin play in the Box Model?

Accepted Answer

The margin is the space outside the border that creates separation between elements. It doesn't affect the size of the element itself but pushes neighboring elements away, creating space around the element.
