📝 Meaningful HTML Markup
Everything is a div? Search engines confused, screen readers lost. Semantic HTML5 uses elements that describe their purpose: <header>, <nav>, <article>, <section>. Better SEO, better accessibility.
❌ Div Soup
<div class="header">
<div class="nav">
<div class="nav-item">Home</div>
</div>
</div>
<div class="main">
<div class="content">...</div>
</div>
✅ Semantic HTML5
<header>
<nav>
<a href="/">Home</a>
</nav>
</header>
<main>
<article>...</article>
</main>
🎯 HTML5 Semantic Elements
