Box Model in CSS

3. Border Box
The border box is the layer that surrounds the padding box. It defines the visible boundary of the element. Borders can have different styles, colors, and sizes, specified using the border property.

The margin box is the remotest layer of the box and represents the space between the element and its neighboring elements. perimeters can be applied to all four sides of the border box, controlling the spacing between elements.
Box Model Properties
To manipulate and control the Box Model, CSS provides several properties that allow you to customize the size, distance, and appearance of elements.
1. Width and Height

2. Padding
The padding property sets the spacing between the content and the border box. It can be specified collectively for each side or using shorthand notation.
3. Border
The border property controls the appearance of the element’s border. You can set the border style, color, and range.
