The CSS box model is essentially a box that wraps around every HTML element. It consists of: margins, borders, padding, and the actual content.
Explanation of the different parts:
- Content - The content of the box, where text and images appear
- Padding - Clears an area around the content. The padding is transparent
- Border - A border that goes around the padding and content
- Margin - Clears an area outside the border. The margin is transparent
The box model allows us to add a border around elements, and to define space between elements.
All HTML elements can be considered as boxes.
In CSS, the term "box model" is used when talking about design and layout.
Example
div {
width: 300px;
border: 25px solid green;
padding: 25px;
margin: 25px;
}
