CSS Box Model
You can think of all HTML components as boxes.
The CSS Box Model
“Box model” is the phrase used in CSS to refer to layout and design.
In essence, the CSS box model is a box that encircles each HTML element. Content, padding, borders, and margins are its constituent parts. The box model is shown in the following image:

An explanation of the many components:
- Content: The information displayed in the box, including any text and photos
- Padding: Makes space for the content. The cushion is clear.
- Border: A border encircling the text and padding
- Margin: Removes stuff beyond the boundary. The margin is observable.
We may define the spacing between pieces and build
Example
Demonstration of the box model:
div {
width: 300px;
border: 15px solid green;
padding: 50px;
margin: 20px;
}
Width and Height of an Element
Understanding the box model is necessary to set an element’s width and height accurately across all browsers.
Important: You are only setting the width and height of the content area when you use CSS to set an element’s width and height properties. You also need to factor in the padding and borders when figuring out an element’s overall width and height.
Example
This <div> element will have a total width of 350px and a total height of 80px:
div {
width: 320px;
height: 50px;
padding: 10px;
border: 5px solid gray;
margin: 0;
}
Here is the calculation:
320px (width of content area)
+ 20px (left padding + right padding)
+ 10px (left border + right border)
= 350px (total width)
50px (height of content area)
+ 20px (top padding + bottom padding)
+ 10px (top border + bottom border)
= 80px (total height)
The total width of an element should be calculated like this:
Total element width = width + left padding + right padding + left border + right border
The total height of an element should be calculated like this:
Total element height = height + top padding + bottom padding + top border + bottom border
Note: The margin is not part of the box’s actual size; rather, it just influences how much space the box will occupy overall on the page. The border marks the end of the box’s overall width and height.
