What Are HTML5 Semantic Elements?

HTML5 semantic elements are specific HTML tags that define the meaning and structure of content on a web page. They provide additional meaning to the content they wrap around, beyond just the visual presentation, and help search engines, assistive technologies, and other web applications to better understand and process the page.

Here’s a list of HTML5 semantic elements and their usage:

<header>:

This element is used to represent the header of a document or section. It typically contains introductory content such as the title, logo, and navigation links.

<header>
  <nav>
    <ul>
      <li><a href="#home">Home</a></li>
      <li><a href="#about">About</a></li>
      <li><a href="#contact">Contact</a></li>
    </ul>
  </nav>
  <h1>Welcome to my website</h1>
</header>

<nav>:

This element represents a section of a page that contains navigation links, usually to other pages within the same website.

<header>
  <nav>
    <ul>
      <li><a href="#home">Home</a></li>
      <li><a href="#about">About</a></li>
      <li><a href="#contact">Contact</a></li>
    </ul>
  </nav>
</header>

<main>:

This element represents the main content of a document, and should only be used once per page. It should not include content that is repeated across multiple pages such as headers, footers, or navigation links.

  <p>I have experience with HTML, CSS, and JavaScript, and I am always looking to expand my skills and knowledge.</p>

<article>:

This element represents a standalone, self-contained piece of content, such as a blog post, news story, or forum thread. Each <article> element should be able to be independently syndicated or distributed without losing its context or meaning.

  <p>In this post, I will be discussing the latest trends in web development and how to stay up-to-date in this ever-changing field.</p>

</section>

  </ul>

<aside>:

This element represents content that is tangentially related to the main content and is typically displayed in a sidebar or aside area.
