title: Highlight selected tab in menu
body: <p>I have the following tabbed navigation setup in my master page:</p>
  
  <pre><code>&lt;div id="header"&gt;
              &lt;div id="logo"&gt;
                  &lt;a href="../default.aspx"&gt;Logo&lt;/a&gt;
              &lt;/div&gt;
              &lt;div id="menu"&gt;
                  &lt;div class="buttons"&gt;
                  &lt;ul&gt;
                      &lt;li&gt;&lt;a href="../default.aspx"&gt;Home&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="../books/books.aspx"&gt;Books&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="../contacts/aboutus.aspx"&gt;About Us&lt;/a&gt;&lt;/li&gt;
                      &lt;li&gt;&lt;a href="../contacts/contact.aspx"&gt;Contact Us&lt;/a&gt;&lt;/li&gt;
                  &lt;/ul&gt;
                  &lt;/div&gt;
              &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>For example when I click Home tab, I'd like it to remain highlighted (ex. <code>background-color: #1087a4;</code>). What is the recommended way to accomplish this? And does this have to be implemented in the Master Page?</p>
