    copied!<p>I have different divs and a menuebar which constis out of LI-elements.</p> <pre><code>&lt;ul&gt; &lt;li&gt;&lt;a href="#first" id="nav1" title="Next Section"&gt;FIRST&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#second" id="nav2" title="Next Section"&gt;SECOND&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#third" id="nav3" title="Next Section"&gt;THIRD&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="#fourth" id="nav4" title="Next Section"&gt;FOURTH&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; </code></pre> <p>The names of the div are #first to #fourth.</p> <p>If one of the DIVs (or more) is/ are in the viewport I want to change the color of the bottom-border for the li-element which links to this DIV.</p> <p>For example: If DIV #third is in viewport the third LI-element (#nav3) should change its bottom-border to green. If it leaves the viewport it should change to white again.</p> <ul> <li>Just for the time the DIV is in the viewport. As soon it leaves the viewport I want to undo the color change.</li> </ul> <p>I tried it with jQuery Viewport: <a href="http://www.appelsiini.net/projects/viewport" rel="nofollow">http://www.appelsiini.net/projects/viewport</a></p> <p>My problem is that I can't figure out how to use this selector - I know it's basic stuff but I really can't figure it out.</p> <pre><code>$("#third:in-viewport").each(function() { $("#nav1, #nav2, #nav4").animate({ borderBottomColor: '#fff' },800); $("#nav3").animate({ borderBottomColor: 'green' },800); }); </code></pre> <p>Would be awesome if somebody could help me with this. Thanks a lot!</p>
