Here's an example of a styled VerseClick link and popup.

These are the CSS rules applied:

.vcVerseLink {
	/* style the verse link with the color red and a dotted red underline. */
	color:#F00;
	border-bottom:1px dotted #F00;
	text-decoration:none;
}
.vcVerseLink:hover {
	/* style verse link hover so that it changes to blue */
	color:#00F;
	border-bottom:1px dotted #00F;
}
.vcPopupVerseText {
	/* Change the background color and font of the verse text area in the popup */
	background-color:#FFF2CB;
	color:#000;
	font-family:Georgia, "Times New Roman", Times, serif;
}
.vcPopupHeaderText {
	/* and change the styles for the header. */
	background-color:#d7c08b;
	color:#000;
	font-family:"Trebuchet MS", Arial, Helvetica, sans-serif;
	font-size:1.2em;
}
