CSS Box Model: The CSS box model is a fundamental concept of web design that defines the layout and positioning of HTML elements on a web page. Every HTML element is represented as a rectangular box, which consists of several components:
Content: This is the actual content of the HTML element, such as text, images, or videos.
Padding: This is the space between the content and the border of the element. Padding can be used to create spacing and improve the readability of the content.
Border: This is the line that surrounds the content and padding of the element. The border can be styled with different colours, thicknesses, and styles.
Margin: This is the space between the border of the element and the adjacent elements. Margins can be used to create spacing and improve the layout of the web page.
Note: The total width of an element is the sum of its content, padding, border, and margin. When we start designing a web page, it's important to consider the box model to ensure that elements are properly positioned and spaced. CSS provides several properties that can be used to adjust the box model, such as padding, border, and margin.
