}
ul ul{
display:none;
position:relative; /* updated */
z-index:2; /* updated */
}
ul li:hover ul{

}
HTML 代码，
<nav><ul class="fancyNav">
<li id="quemsomos" class="menlog"><a href="index.php"><img src="imgs/Logo.png" width="37" height="45" /></a></li>
<li id="quemsomos"><a href="quemsomos.php?web=1"><font face="din" size="4">QUEM SOMOS</font></a>
