How to build a Portfolio website with HTML, CSS & JavaScript

Hello everyone, today we are going to build a portfolio website with HTML, CSS & JavaScript.

We will not use any other library or framework, just vanilla CSS & JavaScript.

So, let’s get started.

If you prefer video content then check this one out.:

Prerequisite:

To follow along you don’t need to be a pro at anything, all you need is the fundamentals:

  1. The fundamentals of Html & CSS
  2. The fundamentals of JavaScript.

Setup:

Before we start we’ll have to set up the project. For the setup, you won’t have to do much.

Just create these files:

  1. Index.html
  2. Styles.css
  3. Script.js

and then include this code snippet in the Index.html file:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Document</title>
    <link
      href="https://fonts.googleapis.com/css2?family=Poppins:wght@200;300;400;500;700&display=swap"
      rel="stylesheet"
    />
    <link
      rel="stylesheet"
      href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.3.0/css/all.min.css"
    />
    <link rel="stylesheet" href="style.css" />
  </head>
  <body>

        <script src="./script.js"></script>
  </body>
</html>
Enter fullscreen mode Exit fullscreen mode

Then add this to the styles.css file:

* {
  box-sizing: border-box;
  margin: 0;
}

:root {
  --primary: #03011c;
  --secondery: #1c1847;
  --accent: #0cb8c2;
  --text: #fff;
}

html {
  scroll-behavior: smooth;
}

body {
  background: var(--primary);
  font-family: Poppins, sans-serif;
}

a {
  text-decoration: none;
  color: var(--text);
}

img {
  width: 100%;
}
Enter fullscreen mode Exit fullscreen mode

Also include the utility classes too:

/* utility classes */
.container {
  padding: 4rem 2rem;
  color: var(--text);
}

.highlighted {
  color: var(--accent);
}

.hidden {
  display: none;
}

.btn {
  background-color: var(--accent);
  color: var(--text);
  padding: 0.5rem 3rem;
  border-radius: 5rem;
  display: inline-block;
  margin-top: 2rem;
  border: 2px solid var(--accent);
}

.btn:hover {
  background-color: transparent;
  color: var(--accent);
}
Enter fullscreen mode Exit fullscreen mode

So, the setup is done!
Let’s start building.

The Sections:

Before we start let’s look at how I structured the project.

Our portfolio website has 5 sections.

  1. Home
  2. About
  3. Services
  4. Projects and
  5. Contact

1. Home:

This section includes the header and the hero section.

Let’s build the header first.

Header HTML:

The header consists of the logo, nav links, and mobile menu toggler.

    <header>
      <nav class="nav">
        <a href="/" class="logo"> <span class="highlighted"> O</span>liver</a>

        <div class="nav-links">
          <a href="#home" class="nav-item nav-item-active">Home</a>
          <a href="#about" class="nav-item">About</a>
          <a href="#services" class="nav-item">Services</a>
          <a href="#projects" class="nav-item">projects</a>
          <a href="#contact" class="nav-item">contact</a>
        </div>

        <div class="toggler">
          <span class="line"></span><span class="line"></span
          ><span class="line"></span>
        </div>
      </nav>
    </header>
Enter fullscreen mode Exit fullscreen mode

One quick note before we move on to CSS. We are going to follow the mobile-first approach here, we will at the desktop design at the end.

Header CSS:

/* Header style */
.nav {
  background-color: var(--secondery);
  display: flex;
  justify-content: space-between;
  padding: 0.5rem 1rem;
  position: fixed;
  width: 100%;
}

.logo {
  font-weight: 700;
  font-size: 1.5rem;
}

.nav-links {
  position: absolute;
  display: flex;
  flex-direction: column;
  top: 50px;
  background-color: var(--secondery);
  width: 100%;
  left: -200%;
  padding: 1rem;
  transition: left 0.5s ease;
}

.nav-active {
  left: 0;
}

.nav-item {
  font-size: 0.8rem;
  opacity: 0.7;
  display: block;
  text-align: center;
  margin-bottom: 1rem;
  text-transform: capitalize;
  position: relative;
}

.nav-item::after {
  content: "";
  display: block;
  width: 100%;
  height: 2px;
  background-color: rgb(56, 56, 56);
  margin-top: 0.5rem;
}

.nav-item:hover {
  opacity: 1;
}

.nav-item-active::after {
  background-color: var(--accent);
  opacity: 1;
}

.toggler .line {
  width: 30px;
  height: 2px;
  display: block;
  background-color: var(--text);
  margin: 5px;
}
Enter fullscreen mode Exit fullscreen mode

Header JavaScript:

We have to add the javascript to make the toggler and the nav-item’s active state work.
Here’s the code, add it to the script.js file.

const toggler = document.querySelector(".toggler");
const navLinks = document.querySelector(".nav-links");
const navItems = document.querySelectorAll(".nav-item");

// show and hide navbar in mobile
toggler.addEventListener("click", () => {
  navLinks.classList.toggle("nav-active");
});

// add active class on click to nav-items
navItems.forEach((item) => {
  item.addEventListener("click", function () {
    navItems.forEach((i) => i.classList.remove("nav-item-active"));
    this.classList.add("nav-item-active");

    navLinks.classList.toggle("nav-active");
  });
});
Enter fullscreen mode Exit fullscreen mode

That’s the section. Let’s add the hero section.

Hero HTML

<section class="hero container" id="home">
       <div class="hero-info">
        <h1 class="title">Oliver <span class="highlighted">Queen</span></h1>
        <p class="hero-description">Web developer based in Starling City.</p>
        <a href="#services" class="btn hero-btn">Services</a>
      </div>

      <div class="hero-img">
        <img src="./images/hero-img.png" alt="Oliver Queen" />
      </div>
 </section>
Enter fullscreen mode Exit fullscreen mode

Hero CSS:

/* Hero styles */
.hero {
  display: flex;
  flex-direction: column-reverse;
  justify-content: center;
  align-items: center;
  color: var(--text);
}

.hero-img {
  padding-top: 2rem;
}

.hero-info {
  text-align: center;
  padding-top: 3rem;
}

.title {
  font-size: 2.5rem;
}

.hero-description {
  opacity: 0.7;
}

  .description {
