Box Model: Margin, Padding, and Border

Understanding the CSS box model is crucial. It forms the foundation of how elements are displayed and positioned on a webpage. The box model consists of four main components: content, padding, border, and margin. In this documentation, we'll delve into each of these components, exploring their properties and how they interact with each other.

1. Content:

The content area of an element is where the actual content, such as text or images, is displayed. It is defined by the width and height properties. Any padding, border, or margin applied to an element does not affect the size of the content area.

.content-box {
    width: 200px;
    height: 100px;
    background-color: lightblue;
}

2. Padding:

Padding is the space between the content area and the element's border. It helps in controlling the spacing within an element. Padding can be set individually for each side (top, right, bottom, left), or all sides together.

.padding-example {
    padding: 20px; /* Applies 20 pixels of padding to all sides */
}

3. Border:

Borders surround the padding of an element and can be styled using various properties such as width, color, and style. Similar to padding, borders can be set for each side individually or for all sides together.

.border-example {
    border: 2px solid black; /* Applies a 2-pixel solid black border to all sides */
}

4. Margin:

Margins are the space outside the element's border. They define the distance between adjacent elements. Like padding and border, margins can be set for each side individually or all sides together.

.margin-example {
    margin: 10px; /* Applies a 10-pixel margin to all sides */
}
