Project - Portfolio Website (Part 1) using Bootstrap
Objective:
In this
class, we will begin building a personal portfolio website using Bootstrap,
a popular front-end framework. The website will showcase personal information,
skills, and projects, and will be structured using Bootstrap's responsive grid
system.
By the
end of this session, students will have:
- A
basic understanding of Bootstrap components like the header, navigation
bar, and grid-based layout.
- Started
building their personal portfolio website.
Introduction
to Portfolio Websites
A portfolio
website is a personal website that serves as a digital resume. It’s a
place to showcase your work, skills, experiences, and any projects you've
worked on. Portfolio websites are crucial for professionals in creative and
tech fields like web development, graphic design, and writing.
A
portfolio website typically includes:
1.
Home/Introduction Section:
A brief about you.
2.
Skills/Expertise Section:
What you can do.
3.
Project Gallery: Examples of your
work.
4.
Contact Information: How people can
reach you.
Overview
of Bootstrap
Bootstrap is an open-source front-end
framework for building responsive, mobile-first websites quickly. It comes with
pre-built components such as buttons, forms, navigation bars, and grids that
make web development faster and easier.
Key
Features of Bootstrap:
- Responsive Grid System:
Bootstrap's grid system helps structure your page and adjust layouts for
different screen sizes (mobile, tablet, desktop).
- Pre-designed Components:
Buttons, navigation bars, cards, forms, etc.
- Utilities:
Spacing, text alignment, background colors, and more.
Setting
Up the Project
Before we
start building the portfolio, let's set up a basic HTML page with the necessary
Bootstrap files.
Step 1:
Create the HTML Structure
1.
Create a new folder on your computer,
named portfolio_website.
2.
Inside this folder, create a file named index.html. This will be the
main HTML file for your website.
Here’s
the basic structure of an HTML file that will use Bootstrap:
html<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Your Portfolio</title> <!-- Bootstrap CSS --> <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.1/dist/css/bootstrap.min.css" rel="stylesheet"></head><body> <!-- Content will go here --> <!-- Bootstrap JS and dependencies --> <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.11.6/dist/umd/popper.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.1/dist/js/bootstrap.min.js"></script></body></html>
- The
metatags help the website be responsive by setting the viewport properties. - The
<link>tag links the Bootstrap CSS file for styling. - The
<script>tags include Bootstrap’s JavaScript and Popper.js, which are needed for some Bootstrap components like dropdowns and modals.
Building
the Header
A header
typically contains the website's title and navigation links. We will create a
header with the website's name and a navigation bar using Bootstrap's built-in
classes.
Step 2:
Add a Header and Navigation Bar
Inside
the <body>
tag, add the following code for the header and navigation bar:
html<header class="bg-dark text-white p-4"> <div class="container"> <h1>Your Portfolio</h1> <nav> <ul class="nav"> <li class="nav-item"> <a class="nav-link text-white" href="#home">Home</a> </li> <li class="nav-item"> <a class="nav-link text-white" href="#about">About</a> </li> <li class="nav-item"> <a class="nav-link text-white" href="#projects">Projects</a> </li> <li class="nav-item"> <a class="nav-link text-white" href="#contact">Contact</a> </li> </ul> </nav> </div></header>
Explanation:
class="bg-dark text-white p-4": This sets a dark background with white text and some padding around the header.<div class="container">: This is a Bootstrap class that provides a responsive fixed-width container for content.<nav>and<ul>: These elements create a navigation bar using an unordered list for links.class="nav-link text-white": This makes the links white and applies Bootstrap’s styles to the navigation links.
Grid-Based
Layout
Bootstrap’s
grid system allows you to create a flexible layout for your
portfolio website. The grid system is based on 12 columns, and you can divide
the page into rows and columns.
Step 3:
Add a Grid Layout
Now,
let’s add a grid-based layout to the main content area. We'll structure it in
rows and columns to display sections like "About Me",
"Skills", and "Projects."
html<main class="container my-5"> <div class="row"> <!-- About Section --> <div class="col-md-4"> <h2 id="about">About Me</h2> <p>Write a short introduction about yourself here.</p> </div> <!-- Skills Section --> <div class="col-md-4"> <h2>Skills</h2> <ul> <li>Web Development</li> <li>Graphic Design</li> <li>Project Management</li> </ul> </div> <!-- Projects Section --> <div class="col-md-4"> <h2 id="projects">Projects</h2> <ul> <li>Project 1</li> <li>Project 2</li> <li>Project 3</li> </ul> </div> </div></main>
Explanation:
- The
containerclass wraps the main content to provide a responsive layout. - The
rowclass defines a row for the grid. - The
col-md-4class defines a column that spans 4 out of the 12 available grid columns, meaning three columns will fit in one row on medium-sized screens and larger. - Inside
each column, we add headings and content (about, skills, and projects).
Final
Structure
Putting
everything together, the final structure of your index.html
file will look like this:
html<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Your Portfolio</title> <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.1/dist/css/bootstrap.min.css" rel="stylesheet"></head><body> <header class="bg-dark text-white p-4"> <div class="container"> <h1>Your Portfolio</h1> <nav> <ul class="nav"> <li class="nav-item"> <a class="nav-link text-white" href="#home">Home</a> </li> <li class="nav-item"> <a class="nav-link text-white" href="#about">About</a> </li> <li class="nav-item"> <a class="nav-link text-white" href="#projects">Projects</a> </li> <li class="nav-item"> <a class="nav-link text-white" href="#contact">Contact</a> </li> </ul> </nav> </div> </header> <main class="container my-5"> <div class="row"> <div class="col-md-4"> <h2 id="about">About Me</h2> <p>Write a short introduction about yourself here.</p> </div> <div class="col-md-4"> <h2>Skills</h2> <ul> <li>Web Development</li> <li>Graphic Design</li> <li>Project Management</li> </ul> </div> <div class="col-md-4"> <h2 id="projects">Projects</h2> <ul> <li>Project 1</li> <li>Project 2</li> <li>Project 3</li> </ul> </div> </div> </main> <script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.11.6/dist/umd/popper.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.1/dist/js/bootstrap.min.js"></script></body></html>
