</a>

Different Types of Links

<a href="https://www.google.com" target="_blank" rel="noopener">Google Search</a>
<a href="https://www.github.com" target="_blank" rel="noopener">GitHub</a>

Internal Links

<!-- Links within your website -->
<a href="about.html">About Us</a>
<a href="contact.html">Contact</a>
<a href="../index.html">Home</a>

Anchor Links (Same Page)

Anchor Links

<!-- Jump to sections on the same page -->
<a href="#introduction">Go to Introduction</a>
<a href="#conclusion">Jump to Conclusion</a>

<!-- Target elements need IDs -->
<h2 id="introduction">Introduction</h2>
<h2 id="conclusion">Conclusion</h2>

Communication Links

Email and Phone Links

<a href="mailto:info@example.com">Send Email</a>
<a href="mailto:support@example.com?subject=Help Request">Get Support</a>

<!-- Phone links -->
<a href="tel:+1234567890">Call Us: (123) 456-7890</a>
<a href="sms:+1234567890">Send SMS</a>

🌐 External Links

Use full URLs (http/https)
Add target="_blank" for new tab
Include rel="noopener" for security
Consider user experience

🏠 Internal Links

Use relative paths
Stay within your website
Faster loading (no new domain)

Navigation Menus

Good navigation helps users find content easily and understand site structure.

Build a Navigation Menu

    <title>Navigation Demo</title>
    <style>
        nav ul {
            list-style: none;
            padding: 0;
            display: flex;
            background: #2563eb;
            margin: 0;
        }
        nav li {
            margin: 0;
        }
        nav a {
