Creating an efficient and visually appealing layout is crucial for any website. HTML provides a variety of elements and techniques to help structure content and layout web pages.

1. Key HTML Layout Elements

HTML5 introduced several semantic elements specifically designed for web layouts. These elements improve the readability of your HTML code and enhance accessibility.

a. <header>

Defines a header for a webpage or a section.

<header>
  <h1>My Website</h1>
  <nav>
    <a href="#home">Home</a>
    <a href="#about">About</a>
    <a href="#contact">Contact</a>
  </nav>
</header>

---

b. <nav>

Represents navigation links.

<nav>
  <ul>
    <li><a href="#home">Home</a></li>
    <li><a href="#services">Services</a></li>
    <li><a href="#contact">Contact</a></li>
  </ul>
</nav>

---

c. <main>

Specifies the main content of the document, which is unique and central to the page.

<main>
  <h2>Welcome to Our Site</h2>
  <p>This is where the main content goes.</p>
</main>

---

d. <section>

Groups related content together, typically with its own heading.

<section>
  <h2>Our Services</h2>
  <p>We provide high-quality web design and development services.</p>
</section>

---

e. <article>

Represents standalone content like blog posts, articles, or news.

<article>
  <h2>Latest News</h2>
  <p>Our company has launched a new product today!</p>
</article>

---

f. <aside>

Contains secondary or side content, such as a sidebar or advertisements.

<aside>
  <h3>Related Links</h3>
  <ul>
    <li><a href="#link1">Link 1</a></li>
    <li><a href="#link2">Link 2</a></li>
  </ul>
</aside>

---

g. <footer>

Defines the footer for a webpage or a section, often containing copyright or contact information.

<footer>
  <p>&copy; 2025 My Website. All rights reserved.</p>
</footer>

2. Common HTML Layout Techniques

a. Using <div> for Layout

Before semantic elements, <div> was commonly used for layout purposes. It’s still useful for grouping elements but should now be used with appropriate classes or IDs.

<div class="container">
  <div class="header">Header</div>
  <div class="content">Content</div>
  <div class="footer">Footer</div>
</div>

---

b. Grid-Based Layouts

Grids are popular for creating responsive designs. They divide the page into rows and columns.

CSS Grid Example

<div class="grid-container">
  <header>Header</header>
  <nav>Nav</nav>
  <main>Main Content</main>
  <aside>Sidebar</aside>
  <footer>Footer</footer>
</div>

<style>
  .grid-container {
    display: grid;
    grid-template-areas:
      "header header"
      "nav main"
      "nav aside"
      "footer footer";
    grid-gap: 10px;
  }
  header { grid-area: header; }
  nav { grid-area: nav; }
  main { grid-area: main; }
  aside { grid-area: aside; }
  footer { grid-area: footer; }
</style>

---

c. Flexbox Layout

Flexbox is ideal for one-dimensional layouts, such as aligning items in rows or columns.

Flexbox Example

<div class="flex-container">
  <div class="box">Box 1</div>
  <div class="box">Box 2</div>
  <div class="box">Box 3</div>
</div>

<style>
  .flex-container {
    display: flex;
    justify-content: space-around;
    align-items: center;
  }
  .box {
    background: lightblue;
    padding: 20px;
    margin: 5px;
    text-align: center;
  }
</style>

---

d. Responsive Design

Responsive design ensures the layout adjusts for different screen sizes using CSS Media Queries.

Media Query Example

<style>
  body {
    font-family: Arial, sans-serif;
  }
  .container {
    display: grid;
    grid-template-columns: 1fr 1fr;
  }
  @media (max-width: 768px) {
    .container {
      grid-template-columns: 1fr;
    }
  }
</style>

<div class="container">
  <div>Column 1</div>
  <div>Column 2</div>
</div>

---

3. Advanced Layout Techniques

a. CSS Frameworks

Frameworks like Bootstrap and Tailwind CSS provide pre-built classes for layout design.

<div class="container">
  <div class="row">
    <div class="col-6">Left Column</div>
    <div class="col-6">Right Column</div>
  </div>
</div>

---

b. Using CSS Variables for Consistent Layouts

<style>
  :root {
    --gap: 20px;
  }
  .layout {
    display: grid;
    gap: var(--gap);
  }
</style>
<div class="layout">
  <div>Item 1</div>
  <div>Item 2</div>
</div>

4. Example of a Complete HTML Layout

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Website Layout</title>
  <style>
    .container {
      display: grid;
      grid-template-areas:
        "header header"
        "nav main"
        "footer footer";
      gap: 20px;
    }
    header { grid-area: header; background: #f4f4f4; padding: 20px; }
    nav { grid-area: nav; background: #ddd; padding: 20px; }
    main { grid-area: main; background: #eee; padding: 20px; }
    footer { grid-area: footer; background: #ccc; padding: 20px; }
  </style>
</head>
<body>
  <div class="container">
    <header>Header</header>
    <nav>Navigation</nav>
    <main>Main Content</main>
    <footer>Footer</footer>
  </div>
</body>
</html>
