title: Hamburger menu to close upon clicking links
body: <p>I have created a simple Hamburger menu I would like to close when you click on one of the links but I do not know how to do this. My HTML is:</p>
  
  <pre><code>&lt;nav&gt;
  
              &lt;div class="nav_top"&gt;
  
                  &lt;div class="nav_logo"&gt;
                      &lt;img src="images/nav_logo.png"&gt;
                  &lt;/div&gt;  &lt;!-- end of nav_logo --&gt;
  
              &lt;/div&gt; &lt;!-- end of nav_top --&gt;
  
              &lt;div class="hamburger" id="hamburger"&gt;
                      &lt;img src="images/hamburger.svg"&gt;
                  &lt;/div&gt;      
  
              &lt;div class="list-items"&gt;
                  &lt;ul&gt;
                      &lt;li&gt;&lt;a href="#welcome"&gt;WELCOME&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#venue"&gt;VENUE&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#accommodation"&gt;ACCOMMODATION&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#gifts"&gt;GIFTS&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#weekend"&gt;WEEKEND&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="#RSVP"&gt;RSVP&lt;/a&gt;&lt;/li&gt;
                  &lt;/ul&gt;
              &lt;/div&gt;
  
          &lt;/nav&gt; &lt;!-- end of navigation section --&gt;
  </code></pre>
  
  <p>My jQuery is:</p>
  
  <pre><code>jQuery(function($){
           $( '.hamburger' ).click(function(){
           $('.list-items').toggleClass('expand')
           })
      })
  </code></pre>
  
  <p>Is there something simple I can add to the jQuery to get this to work? Cheers</p>
