<!-- Subdirectory -->
<a href="products/software.html">Our Software</a>

<!-- Parent directory -->
<a href="../contact.html">Contact</a>

Internal links keep users on your site:

Home | About | Services | Contact

External Links

Links to other websites

<!-- Basic external link -->
<a href="https://google.com">Google</a>

<!-- With security attributes -->
<a href="https://external.com"
   target="_blank"
   rel="noopener noreferrer">
  External Site
</a>

<!-- No-follow for SEO -->
<a href="https://partner.com" rel="nofollow">
  Partner Site
</a>

External links open other websites:

Google ↗ | GitHub ↗ | Stack Overflow ↗

Anchor Links (Page Sections)

⚓

Creating Anchors

Define target sections with id attributes

<h2 id="introduction">Introduction</h2>
<section id="features">
  <h3>Features</h3>
  ...
</section>
<div id="contact">...</div>
🔗

Linking to Anchors

Create links that jump to sections

<!-- Same page -->
<a href="#introduction">Go to Intro</a>

<!-- Different page -->
<a href="page.html#section">
  Specific Section
</a>

<!-- Back to top -->
<a href="#">Back to Top</a>
🎯

Smooth Scrolling

CSS for smooth anchor navigation

html {
  scroll-behavior: smooth;
}

/* Or for specific elements */
.smooth-scroll {
  scroll-behavior: smooth;
}

Anchor Links in Action:

Section 1 Section 2 Section 3 Back to Top

Section 1 Content

This is the first section. Anchor links jump directly to this content.

Section 2 Content

This is the second section. Notice how the URL changes when you click the links.

Section 3 Content

This is the third section. Anchor links are great for long pages and documentation.
