In this section, we will delve into two fundamental concepts of the CSS Box Model: margin and padding. Understanding these properties is crucial for controlling the spacing and layout of elements on a webpage.
What are Margin and Padding?
- Margin: The space outside the border of an element. It creates space between the element and its neighboring elements.
- Padding: The space inside the border of an element. It creates space between the content of the element and its border.
