<p>Stop Overusing Divs! A Practical Guide to Semantic HTML Best Practices

<p>This guide explores the advantages of using semantic HTML elements over divs. Let's examine a few practical examples.

<p>Why choose semantic tags over divs? The benefits are significant:

  1. Improved Readability: Well-structured semantic HTML is easier to read and understand.
  2. Enhanced SEO: Search engines readily index semantically correct content, boosting your search ranking.
  3. Better Accessibility: Screen readers and assistive technologies efficiently categorize and index your website.
  4. Overall Better Practice: It's simply a best practice for web development.
<p>Example: A Typical Semantic HTML Structure

<p>Here's a common HTML boilerplate showcasing semantic elements:

<header>
  <img src="/static/imghw/default1.png"  data-src="logo.png"  class="lazy"  alt="Stop Overusing Divs! A Practical Guide to Semantic HTML Best Practices">
  <nav>
    <ul>
      <li><a href="/">Home</a></li>
      <li><a href="/about">About</a></li>
    </ul>
  </nav>
</header>
<main>
  <h2>About Us</h2>
  <p>Lorem ipsum...</p>
  <h2>How It Works</h2>
  <p>Lorem ipsum...</p>
  <aside>Sidebar content...</aside>
</main>
<footer>
  <p>Terms & Conditions</p>
</footer>
<p>Explanation:

  • <header>: Contains the logo and primary navigation.
  • <nav>: Houses the main navigation links.
  • <main>: Encloses the primary content of the page.
  • <h2> and <p>: Structure the main content logically.
  • <aside>: Represents secondary content, like a sidebar.
  • <footer>: Includes less crucial information, such as terms and conditions.
<p>MDN Web Docs Example

<p>Observe the structure of MDN's JavaScript guide page:

<main>
  <h1>JavaScript Guide</h1>
  <p>Learn JavaScript...</p>
  <nav>
    <ul>
      <li><a href="#toc">Table of Contents</a></li>
    </ul>
  </nav>
</main>
<p>Key takeaways:

  • The <main> element clearly defines the core content. It's self-contained and reusable.
  • Navigation is appropriately placed within the <main> section as it's crucial to the guide's usability.
<p>When to Use divs

<p>Use divs only for styling or layout when no semantic element accurately reflects the content's meaning.

<div>
  <p>Why a div here?  The info-bar groups unrelated elements (breadcrumbs and a button) purely for layout; they lack a shared semantic purpose.</p>
  <h2>Summary</h2>
  <p>Use semantic tags when:</p>
  <ul>
    <li>Content is related (<article>).</li>
    <li>It's self-contained (<article>).</li>
    <li>It's critical navigation (<nav>).</li>
    <li>It's secondary content (<aside>).</li>
  </ul>
  <p>Use divs when:  You need a container solely for styling.</p>

What is 'render-blocking CSS'? What is 'render-blocking CSS'? Jun 24, 2025 am 12:42 AM

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
