Build the Web with

HTML, CSS, and JavaScript

Every website you visit is powered by three core front-end technologies: HTML, CSS, and JavaScript. Together, they form the foundation of modern web development—and learning them is the first step toward creating interactive, professional web pages.

HTML – Structure

HTML (HyperText Markup Language) is the language of web page content. It defines elements like headings, paragraphs, images, links, and forms, giving every page its basic structure. Think of HTML as the blueprint of a building: it describes what is on the page.

HTML on Wikipedia

HTML Example:

<form action="/action_page.php">
  <label for="fname">First name:</label><br>
  <input type="text" id="fname" name="fname" value="John"><br>
  <label for="lname">Last name:</label><br>
  <input type="text" id="lname" name="lname" value="Doe"><br><br>
  <input type="submit" value="Submit">
</form>

CSS – Style

CSS (Cascading Style Sheets) controls the appearance of that structure. Colors, fonts, spacing, and responsive layouts are all handled by CSS. It transforms plain HTML into a polished, attractive design that looks great on any screen.

CSS on Wikipedia

CSS Example:

form > * {
    width: 100%;
}

form {
    font-family: 'Lexend', sans-serif;
    color: #ffffff;
    background-color: #433f37;
    border: 1px solid #292524;
    border-radius: 16px;
    width: 100%;
    padding: 2rem;
}

input {
    color: #aaaaaa;
    background-color: #433f37;
    border: 1px solid #aaaaaa;
    font-family: 'Lexend', sans-serif;
    border-radius: 6px;
    padding: 1rem;
    margin-block: 1rem;
}

input[type="submit"] {
    color: #ffffff;
    background-color: #ea580c;
    border: none;
    margin: 0;
}

JavaScript – Interactivity

JavaScript adds logic and dynamic behavior. It responds to user actions, updates content in real time, validates forms, powers animations, and makes modern web applications come alive.

JavaScript on Wikipedia

JavaScript Example:

let count = 0;
const counter = document.querySelector('#counter');
const button = document.querySelector('#clickBtn');
const floatingNumbers = document.querySelector('#floatingNumbers');

button.addEventListener('click', () => {
  counter.textContent = ++count;

  const floating = Object.assign(document.createElement('div'), {
    textContent: '+1',
    className: 'floating-number'
  });

  const { offsetLeft: x, offsetTop: y } = button;
  Object.assign(floating.style, {
    position: 'absolute',
    left: `${x}px`,
    top: `${y}px`,
    opacity: '1',
    transform: 'translateY(0)',
    transition: 'transform 2s ease-out, opacity 2s ease-out'
  });

  floatingNumbers.append(floating);

  requestAnimationFrame(() => {
    Object.assign(floating.style, {
      transform: 'translateY(-100px)',
      opacity: '0'
    });
  });

  setTimeout(() => floating.remove(), 2000);
});
