The CSS Box Model is the foundation of web layout design. It treats every HTML element as a rectangular box made up of content, padding, border, and margin. Understanding it is essential for accurate sizing and spacing of elements.
Structure of the Box Model:
Content: The actual text, image, or other media inside the element.
Padding: Transparent space between the content and the border.
Border: A visible line surrounding the padding and content.
Margin: Transparent space outside the border, separating the element from others.
Example: Basic Box Model in CSS
div {width: 300px; /* Content width */border: 15px solid green; /* Border thickness */padding: 50px; /* Space inside border */margin: 20px; /* Space outside border */}Copied!✕CopyCalculation of Total Size:
Total Width = content width (300px) + left/right padding (100px) + left/right border (30px) = 430px
Total Height is calculated similarly by adding padding and border to the content height.
