The CSS Box Model and Layouts
Introduction:
Welcome to an insightful journey into the heart of CSS layout – the Box Model.
This concept is pivotal in understanding how to effectively style Web3 frontend applications.
Remember, watching the lesson video will offer a deeper understanding of this topic.
Learning Objectives:
By the end of this lesson, you will be able to:
- Comprehend the CSS Box Model’s components: margin, border, padding, and content.
- Apply the Box Model principles to control layout and design of web elements.
- Enhance the layout of the Token Minter dApp using Box Model properties.

The CSS Box Model Explained:
The CSS Box Model is a fundamental concept that dictates how elements are displayed and interact with each other on the page. It includes:
- Content: The actual content like text or images.
- Padding: Space around the content.
- Border: The boundary surrounding padding and content.
- Margin: Space outside the border. It is transparent and separates one HTML element from another.
Each element on a web page is considered as a box, and understanding this model allows for precise control over layout and spacing.
/* CSS Syntax */
selector {
property: value;
}
Applying the Box Model:
Let’s apply our knowledge to our ongoing project, the Token Minter dApp.
We’ll focus on enhancing the layout and design using the Box Model.
Example Codes for Practical Application:
Expanding the Capstone Project
Expanding on our Token Minter dApp, let’s enhance its features using what you learned from this lesson.
Existing Capstone Project Code from Previous Lesson:
CSS Code:
/* External CSS */
/* Basic styling for the body */
body {
font-family: Arial, sans-serif;
background-color: #f4f4f4;
}
/* Styling for the header using element selector */
header {
background: #333;
color: white;
padding: 10px;
text-align: center;
}
/* Styling navigation menu using child combinator */
nav > ul > li {
display: inline;
margin-right: 20px;
}
/* Styling links using attribute selector */
a[href^="#"] {
text-decoration: none;
color: white;
}
/* Targeting specific section with ID selector */
#mint {
background-color: #eaeaea;
padding: 15px;
margin-top: 10px;
}
/* Styling paragraph using adjacent sibling combinator */
h2 + p {
color: #630404;
}
/* Applying Box Model to the paragraph */
article p {
margin-bottom: 20px;
border: 1px solid grey;
padding: 15px;
}
