🔍 What Are HTML Semantic Tags?

Semantic tags are HTML elements that clearly describe their meaning in a human- and machine-readable way. Unlike non-semantic tags like <div> and <span>, which tell nothing about their content, semantic tags like <header>, <article>, and <footer> convey specific roles in a webpage layout.

💡 Think of semantic tags as labels that help both developers and search engines understand the structure and purpose of your content.

🧩 Why Are Semantic Tags Important?

Here’s why every modern developer should embrace semantic HTML:

✅ Better SEO:
Search engines like Google use these tags to understand your content and rank it better.

✅ Improved Accessibility:
Screen readers rely on semantic tags to navigate and interpret your website for users with disabilities.

✅ Clean & Organized Code:
Makes your HTML more readable and maintainable for both you and other developers.

✅ Faster Development with CSS & JS:
Easier to target specific parts of your page when your tags are meaningful.

💡 Example: Semantic vs Non-Semantic HTML

❌ Non-Semantic HTML:

html
<div id="header">
  <div id="nav">...</div>
</div>
<div id="main-content">...</div>
<div id="footer">...</div>

✅ Semantic HTML:

html
<header>
  <nav>...</nav>
</header>
<main>...</main>
<footer>...</footer>

See the difference? The semantic version is not only cleaner but also easier to understand.
