CSS Box Model is a fundamental concept in web development that defines how HTML elements are displayed as boxes on a web page. It is a core concept that every web developer should understand to create visually appealing and well-organized web pages.
The box model consists of several properties, including padding, border, and margin. Each of these properties plays a crucial role in defining the size, spacing, and overall appearance of an HTML element.
Properties of Box Model
Content Box
The content box is the area that holds the content of an HTML element. This area is where developers can specify the content of an element using HTML tags. The width and height of an element are measured from the edge of the content, excluding the padding, border, and margin.
Padding Box
