The CSS Box Model is the fundamental layout concept describing how every HTML element is rendered as a rectangular box composed of content, padding, border, and margin layers. Web developers rely on it to calculate element sizing and spacing precisely, and to understand how properties like box-sizing affect total width and height. Mastery of the box model is essential for debugging layout issues and building consistent page designs.
