The Box Model is essential in controlling the spacing, borders, padding, and margin of elements on the page. We’ll design a simple, clean, and modern blog layout with a header, main content area, sidebar, and footer.
Project Overview
This project will include:
- A header with the blog’s title and navigation links.
- A main content area with a featured article and a grid of blog posts.
- A sidebar with a search bar, categories, and recent posts.
- A footer with some basic information and links.
Step 1: Project Structure
First, create the following files and directories:
blog-project/
│
├── index.html
├── styles.css
└── images/ (optional, for any images you may want to use)
Step 2: HTML Structure
Here’s the HTML structure for the blog layout:
<!DOCTYPE html>

Explanation of the CSS
Box Model Basics:
box-sizing: border-box;
is used globally to ensure that padding and borders are included within the element’s width and height.- Padding, margins, and borders are carefully used to control spacing and element sizes.
Header:
- The header has a dark background with centered text, using padding to create space around the content. Navigation links use padding and border-radius to enhance their hover effect.
Main Content:
- The main content is a flex container with a gap between its child elements. This layout makes it responsive, allowing the sidebar and content to adjust their sizes naturally.
- The
featured-article
andblog-posts
sections use padding, margins, and borders to separate content and create a clean, modern look.
Blog Posts Grid:
- The blog posts are arranged in a grid using
grid-template-columns
andgap
. Each post has padding, a light background, and a hover effect with a box shadow.
- The blog posts are arranged in a grid using
Sidebar:
- The sidebar contains a search bar, categories, and recent posts. Flexbox is used within the search bar to align the input and button. The categories and recent posts lists are styled with padding and hover effects.
Footer:
- The footer has a consistent background color with centered text. Links change color on hover, improving the user experience.

Experiment with Colors:
- Modify the background colors and text colors across the different sections to personalize the design to your taste.
Responsive Design:
- Add media queries to change the layout on smaller screens, such as stacking the sidebar below the content instead of beside it.
Step 4: Viewing the Project
- Save the
index.html
andstyles.css
files in your project directory. - Open the
index.html
file in your web browser to see your modern blog-style webpage in action.
This project provides a solid foundation for understanding and practicing the CSS Box Model in a real-world layout, allowing you to control spacing, borders, padding, and layout with precision.
Practice Task 1: Adjust Spacing
Objective: Experiment with the padding and margin values in the .main-content
, .post
, and .sidebar
sections to see how it affects the layout.
Solution:
- You can change the padding and margin values in the
.main-content
,.post
, and.sidebar
sections to see how they alter the spacing. Here are a few examples:
/* Adjusting the spacing in the main content */
.main-content {
display: flex;
gap: 40px; /* Increased gap between sections */
margin-top: 40px; /* Increased top margin */
}
/* Adjusting padding and margin in the post items */
.post {
background-color: #f8f9fa;
padding: 30px; /* Increased padding inside the post */
border: 1px solid #ddd;
border-radius: 8px;
margin-bottom: 20px; /* Added margin to separate posts vertically */
}
/* Adjusting spacing in the sidebar */
.sidebar {
flex: 1;
background-color: white;
padding: 30px; /* Increased padding inside the sidebar */
border: 1px solid #ddd;
border-radius: 8px;
margin-top: 20px; /* Added margin on top to separate from the content */
}
Outcome:
- By increasing the padding and margins, the content becomes more spaced out, providing a cleaner and less crowded layout.
Practice Task 2: Modify Border and Box Shadows
Objective: Change the border color, width, and style for .featured-article
, .post
, and .sidebar
to see how it impacts the design. Adjust the box-shadow
values on the .post
hover effect.
Solution:
- Here are some modifications to the border and box-shadow properties:
/* Modifying border and box-shadow for the featured article */
.featured-article {
flex: 2;
background-color: white;
padding: 20px;
border: 2px dashed #007bff; /* Changed border to dashed with blue color */
border-radius: 10px;
box-shadow: 0 4px 12px rgba(0, 123, 255, 0.2); /* Added a subtle box shadow */
}
/* Modifying border and box-shadow for the post items */
.post {
background-color: #f8f9fa;
padding: 20px;
border: 2px solid #555; /* Changed border color to a darker shade */
border-radius: 10px;
transition: box-shadow 0.3s ease;
}
.post:hover {
box-shadow: 0 6px 12px rgba(0, 0, 0, 0.2); /* Increased box-shadow on hover */
}
/* Modifying border for the sidebar */
.sidebar {
flex: 1;
background-color: white;
padding: 20px;
border: 3px dotted #ff6347; /* Changed border to dotted with tomato color */
border-radius: 10px;
}
Outcome:
- Changing the borders and box shadows creates a distinct style for each section. The dashed and dotted borders make the layout more playful, while box shadows add depth to the design.
Practice Task 3: Change Layout with Flexbox
Objective: Change the flex values (flex: 2
, flex: 3
, etc.) for the .featured-article
, .blog-posts
, and .sidebar
sections to see how they resize relative to each other.
Solution:
- Modify the flex values to control the relative size of each section:
.main-content {
display: flex;
gap: 20px;
margin-top: 20px;
}
/* Adjusting the flex values */
.featured-article {
flex: 3; /* Increased size of featured article */
background-color: white;
padding: 20px;
border: 1px solid #ddd;
border-radius: 8px;
}
.blog-posts {
flex: 2; /* Decreased size of blog posts section */
background-color: white;
padding: 20px;
border: 1px solid #ddd;
border-radius: 8px;
}
.sidebar {
flex: 1; /* Kept the sidebar size the same */
background-color: white;
padding: 20px;
border: 1px solid #ddd;
border-radius: 8px;
}
Outcome:
- The featured article now takes up more space, while the blog posts section is reduced. This change highlights the featured article more prominently in the layout.
Practice Task 4: Experiment with Colors
Objective: Modify the background colors and text colors across the different sections to personalize the design.
Solution:
- Here are some examples of color changes:
.header {
background-color: #282c34; /* Darker background color for header */
color: #61dafb; /* Lighter text color for contrast */
padding: 20px;
text-align: center;
}
.featured-article {
background-color: #f0f8ff; /* Light blue background for the article */
padding: 20px;
border: 1px solid #61dafb;
border-radius: 8px;
}
.post {
background-color: #ffe4b5; /* Soft orange color for the posts */
padding: 20px;
border: 1px solid #cd853f; /* Darker border for contrast */
border-radius: 8px;
}
.sidebar {
background-color: #fafad2; /* Light yellow color for the sidebar */
padding: 20px;
border: 1px solid #bdb76b;
border-radius: 8px;
}
.footer {
background-color: #282c34;
color: #61dafb;
text-align: center;
padding: 20px;
margin-top: 20px;
}
Outcome:
- The use of soft and contrasting colors gives the blog a fresh, modern look. This makes different sections stand out while maintaining a cohesive design.
Practice Task 5: Responsive Design
Objective: Add media queries to change the layout on smaller screens, such as stacking the sidebar below the content instead of beside it.
Solution:
@media (max-width: 768px) {
.main-content {
flex-direction: column;
}
.sidebar {
margin-top: 20px;
}
}
Outcome:
- When the screen width is below 768px, the layout switches to a vertical stack, with the sidebar moving below the main content. This ensures the layout remains user-friendly on smaller screens.
By completing these practice tasks, you’ve explored how to manipulate the Box Model and Flexbox properties to control layout, spacing, and design elements. These exercises will help you gain a deeper understanding of CSS layout techniques and how to apply them in your own projects.
