⚡ Performance Best Practices
Resource Loading Optimization:
<head>
{/* Preload critical resources */}
<link rel="preload" href="critical.css" as="style">
<link rel="preload" href="hero-image.jpg" as="image">
<link rel="preload" href="main-font.woff2" as="font" type="font/woff2" crossorigin>

<link rel="dns-prefetch" href="//analytics.example.com">
{/* Preconnect for critical external resources */}
<link rel="preconnect" href="https://fonts.googleapis.com" crossorigin>
{/* Async CSS loading */}
<link rel="stylesheet" href="styles.css">
<link rel="stylesheet" href="non-critical.css" media="print" onload="this.media='all'">
{/* Critical CSS inline */}
<style>
/* Critical above-the-fold styles */
body { font-family: Arial, sans-serif; }
.hero { background: linear-gradient(45deg, #007bff, #0056b3); }
</style>
</head>
<body>
{/* Lazy loading images */}
<img src="placeholder.jpg" data-src="actual-image.jpg"
alt="Description" loading="lazy" class="lazy">
{/* Picture element for responsive images */}
<picture>
<source media="(min-width: 768px)" srcset="large-image.jpg">
<source media="(min-width: 480px)" srcset="medium-image.jpg">
<img src="small-image.jpg" alt="Description">

{/* Scripts with loading strategies */}
<script src="analytics.js" async></script>
<script src="non-critical.js" defer></script>
<script>
// Inline critical JavaScript
document.addEventListener('DOMContentLoaded', function() {
// Critical functionality
});
</script>
</body>
Minification and Compression:
{/* Use minified versions in production */}
<link rel="stylesheet" href="styles.min.css">
<script src="script.min.js"></script>
{/* Enable compression via server headers */}
{/* These are set server-side, not in HTML */}
{/* Example: Content-Encoding: gzip */}
🔧 Code Organization Best Practices
Clean, Maintainable Code:
{/* Use consistent indentation (2 or 4 spaces) */}

🎯 Quick Quiz
Test Your Knowledge
Which meta tag should always be the first in the <head> section?
-
<title> -
<meta charset="UTF-8" /> -
<meta name="viewport" /> -
<meta name="description" />
Explanation: The character encoding meta tag should always be first to prevent character encoding issues.
Think About It
Why is proper heading hierarchy important for accessibility?
Answer: Screen reader users navigate pages by heading levels. Proper hierarchy ensures they can understand the document structure and navigate efficiently.
🛠️ Practice Exercise
Audit and Fix HTML Code
Task: Review and fix this poorly written HTML code:
Problem Code:

<h2>1. Use Semantic HTML5 Elements</h2>
<p>Semantic HTML provides meaning to your web content rather than just presentation. Using elements like <code><header></code>, <code><nav></code>, <code><main></code>, and <code><article></code> improves accessibility and SEO.</p>
<figure class="code-example">
<figcaption>Example of semantic HTML structure:</figcaption>
<pre><code><header>

<main>

<h1>Article Title</h1>
<p>Article content...</p>
</article>
</main></code></pre>
</figure>
</section>
<section class="article-section">
<h2>2. Ensure Proper Heading Hierarchy</h2>
<p>Maintain a logical heading structure (h1 → h2 → h3) to help screen readers and search engines understand your content hierarchy. Never skip heading levels.</p>
<div class="do-dont">
<div class="do">
<h4>✅ Do:</h4>
<pre><code><h1>Main Title</h1>
<h2>Section Title</h2>
<h3>Subsection Title</h3></code></pre>

<div class="dont">
<h4>❌ Don't:</h4>
<pre><code><h1>Main Title</h1>
<h4>Jump to H4</h4>
<h2>Back to H2</h2></code></pre>
</div>
</div>
</section>
<section class="article-section">
<h2>3. Add Alt Text to Images</h2>
<p>Every meaningful image should have descriptive alt text. For decorative images, use empty alt attributes (<code>alt=""</code>).</p>
