HTML 5 Semantic Elements

Welcome to the lecture on HTML 5 Semantic Elements. HTML 5 introduced a set of semantic elements that provide meaningful structure and improve the accessibility of web pages.

In this lecture on HTML 5 Semantic Elements, you'll learn about the importance of using semantic tags to enhance the structure, organization, and accessibility of web pages. You'll explore semantic elements such as <header>, <nav>, <main>, <article>, <section>, <aside>, and <footer>, and understand their purpose and usage.

Desired Outcomes:

By the end of this lecture, you should be able to:

  • Understand the importance of semantic elements in HTML 5
  • Identify and use semantic elements to improve web page structure and accessibility

The <header> element represents the introductory or navigational content at the top of a webpage or a specific section within a webpage.

Example:

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

In this example, the <header> element contains the website's main heading (<h1>) and a navigation menu (<nav>) providing links to different sections of the website.

The <nav> element represents a section of a webpage that contains navigation links allowing users to navigate through different areas or pages of a website.

Example:

<nav>
    <a href="/">Home</a>
    <a href="/about">About</a>
    <a href="/contact">Contact</a>
</nav>

In this example, the <nav> element contains links to the home, about, and contact pages of a website.

Main

The <main> element represents the main content of a webpage. It should contain unique content that is directly related to the purpose or central topic of the webpage.

Example:

<main>
    <h1>About Us</h1>
    <p>
       Welcome to our website! We are a company dedicated to 
       providing high-quality products and services.
    </p>
</main>

In this example, the <main> element contains information about the company, serving as the main content of the webpage.

Article

The <article> element represents a self-contained composition that can be independently distributed or reused. It can represent blog posts, news articles, forum posts, and more.

Example:

<article>
    <h2>10 Tips for Successful Web Development</h2>
    <p>
         Here are ten essential tips to improve your web development 
         skills and create successful projects.
   </p>
</article>

In this example, the <article> element contains a blog post or article with its title and content.

Section

The <section> element represents a standalone section within a document or a thematic grouping of content. It helps organize and structure the content of a webpage.

Example:

<section>
    <h2>Our Services</h2>
    <p>
         We offer a wide range of services, including web design, 
         development, and digital marketing.
    </p>
</section>

In this example, the <section> element represents a section dedicated to describing the services offered by a company.

Aside

The <aside> element represents content that is related to the main content of a webpage. It can contain sidebars, pull quotes, advertisements, or other supporting information.

Example:

<aside>
    <h3>Related Articles</h3>
    <ul>
       <li><a href="/article1">Article 1</a></li>
       <li><a href="/article2">Article 2</a></li>
       <li><a href="/article3">Article 3</a></li>
    </ul>
</aside>

In this example, the <aside> element contains a list of related articles, providing additional information to the main content.

The <footer> element represents the footer or the bottom section of a webpage. It typically contains copyright information, links to legal documents, and contact details.

Example:

<footer>
    <p>&copy; 2023 My Website. All rights reserved.</p>
    <nav>
       <a href="/privacy">Privacy Policy</a>
       <a href="/terms">Terms of Service</a>
    </nav>
</footer>

In this example, the <footer> element contains copyright information and links to the privacy policy and terms of service pages.

Figure and Figcaption

The <figure> element is used to encapsulate media such as an image, diagram, or chart along with a caption. The <figcaption> element is used within the <figure> element to provide a caption or legend for the content.

Example:

<figure style="margin: 0">
   <img src="https://placehold.co/600x400" alt="A placeholder image"/>
   <figcaption>A placeholder image</figcaption>
</figure>

Now, if we put all of this together to form an actual HTML page and add some CSS, we could get something like this:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <title></title>
    <style>
        main {
            overflow: hidden;
        }
        article {
            width:70%;
            float: left;
        }
        aside {
            width:25%;
            float: right;
        }
    </style>
  </head>
  <body>
    <header>
        <h1>Welcome to My Website</h1>
        <nav>
           <a href="/">Home</a> |
           <a href="/about">About</a> |
           <a href="/contact">Contact</a>
        </nav>
     </header>
     <main>
        <h1>About Us</h1>
        <p>Welcome to our website! We are a company dedicated to providing high-quality products and services.</p>  
          <article>
            <h2>10 Tips for Successful Web Development</h2>
            <p>Here are ten essential tips to improve your web development skills and create successful projects.</p>
            <section>
                <h3>Our Services</h3>
                <p>We offer a wide range of services, including web design, development, and digital marketing.</p>
             </section>
             <section>
                <h3>Our Clients</h3>
                <p>Lorem ipsum</p>
             </section>
         </article>
         <aside>
            <h3>Related Articles</h3>
            <ul>
               <li><a href="/article1">Article 1</a></li>
               <li><a href="/article2">Article 2</a></li>
               <li><a href="/article3">Article 3</a></li>
            </ul>
         </aside>
    </main>
    <footer>
       <p>&copy; 2023 My Website. All rights reserved.</p>
       <nav>
          <a href="/privacy">Privacy Policy</a>
          <a href="/terms">Terms of Service</a>
       </nav>
    </footer>
  </body>
</html>

Putting it all Together

        }
        aside {
