    copied!<p>This little code that I've copied from a tutorial website explaining how to create a pure CSS horizontal menu, just when I thought I've finally understood how it worked, I discovered this thing and basically now I'm trying to reflect on all the things that I've learned in CSS, I'm stuck.</p> <p>So basically the code is like this, CSS.</p> <pre><code>#nav, .nav, #nav .nav li { margin:0px; padding:0px; } #nav li {float:left; display:inline; cursor:pointer; list-style:none; padding:0px 10px 0px 10px; border:1px #000 solid; position:relative;} #nav li ul.first {left:-1px; top:100%;} li, li a {color:#000; text-decoration:none;} #nav .nav li { width:100%; text-indent:10px; line-height:30px; margin-right:10px; border-top:1px #000 solid; border-bottom:1px #000 solid; border-left:none; border-right:none; background:#fff;} #nav li a {display:block; width:inherit; height:inherit;} ul.nav { display:none; } #nav li:hover &gt; a, #nav li:hover { color:#fff; background:#000; } li:hover &gt; .nav { display:block; position:absolute; width:200px; top:-2px; left:50%; z-index:1000; border:1px #000 solid; } li:hover { position:relative; z-index:2000; } </code></pre> <p>and the html,</p> <pre><code>&lt;ul id="nav"&gt; &lt;li&gt;Menu 1 &lt;ul class="nav first"&gt; &lt;li&gt;&lt;a href="#"&gt;Menu 1&lt;/a&gt;&lt;/li&gt; &lt;li&gt;Menu 2&lt;/li&gt; &lt;li&gt;Menu 3&lt;/li&gt; &lt;li&gt;Menu 4&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;li&gt;Menu 2&lt;/li&gt; &lt;li&gt;Menu 3&lt;/li&gt; &lt;li&gt;Menu 4&lt;/li&gt; &lt;/ul&gt; </code></pre> <p>Now this is where the problem begins, in the CSS, on the 9th line, yes, at the <code>li:hover &gt; .nav</code> part, when I change it to <code>#nav li:hover &gt; .nav</code>, the drop down menu just messes up, it won't behave like it should have, and I'm trying to uncover how a simple <code>#nav</code> can mess the layout, I've come up with some theories, but I can't seem to prove them since they contradict with some of the things that I've learned, I really need somehow who can explain this to me, I'm going nuts!</p> <p>If anyone, please, thank you.</p>
