+<h1>Simple Navigation Setup in Jekyll 3.9.0</h1>
+<p>2020-09-29</p>
+<p>I have found that there is a lot of information on the internet in regards to setting up "dynamic" navigation in Jekyll. The problem I've noticed is that a good amount of these implementations are overly complex. Here is the simplest way that I tend to use when building out <code>nav</code> elements in Jekyll (3.9.0 as of this writing).</p>
+<h2>Creating the Directories &amp; Files</h2>
+<p>In your Jekyll project, at the top level, you need to create a directory called <code>_data</code>. Inside this folder we will be creating a new file called <code>navigation.yml</code>. The contents of this file will contain all your navigation links and they are rendered like so:</p>
+<pre><code>- title: Home
+url: /
+
+- title: Articles
+url: /articles/
+
+- title: About
+url: /about/
+</code></pre>
+<h2>Dynamically Rendering the Navigation</h2>
+<p>The next and final step is rendering out the navigation with a simple loop:</p>
+<pre><code>{% for item in site.data.navigation %}
+ &lt;li&gt;
+ &lt;a href=&quot;{{ item.url }}&quot;&gt;&lt;span&gt;{{ item.title }}&lt;/span&gt;&lt;/a&gt;
+ &lt;/li&gt;
+{% endfor %}
+</code></pre>
+<h2>Highlight Current Page</h2>
+<p>It's also very easy to extend this method to add a CSS class based on whether a user is on the currently selected page or not:</p>
+<pre><code>{% for item in site.data.navigation %}
+ &lt;li&gt;
+ {% if item.url == page.url %}
+ &lt;a class=&quot;active&quot; href=&quot;{{ item.url }}&quot;&gt;&lt;span&gt;{{ item.title }}&lt;/span&gt;&lt;/a&gt;
+ {% else %}
+ &lt;a href=&quot;{{ item.url }}&quot;&gt;&lt;span&gt;{{ item.title }}&lt;/span&gt;&lt;/a&gt;
+ {% endif %}
+ &lt;/li&gt;
+{% endfor %}
+</code></pre>
+<pre><code>/* Custom styling for active class */
+li a.active { color: red; }
+</code></pre>
+<p>Congrats! You now have fully functional, dynamic navigation on your Jekyll site.</p>
