Shannon_K on "Photolistic Theme Change Drop Down Menu Color"

I added a drop down menu to my navigation and now my menu has blue boxes around them. How can I remove the border/boxes around my navigation? (http://shannonkramp.com/) Also, how can I net my drop down menu under "Film", so the menu doesn't overlap it?

code in stylesheet.css:

.navigation {
	color: #888;
	font-size: 12px;
	line-height: 18px;
	overflow: hidden;
}
.navigation a:link,
.navigation a:visited {
	color: #888;
	text-decoration: none;
}
.navigation a:active,
.navigation a:hover {
	color: #ff4b33;
}
.nav-previous {
	float: left;
	width: 50%;
}
.nav-next {
	float: right;
	text-align: right;
	width: 50%;
}
#nav-above {
	margin: 0 0 18px 0;
}
#nav-above {
	display: none;
}
.paged #nav-above,
.single #nav-above {
	display: block;
}
#nav-below {
	margin: -18px 0 0 0;
}
