Add arrow to the accordian

Here is some sample CSS that will add a + to indicate there is more content if clicked and a – to indicate an item is collapsible (when open). It will also add the pointer mouse cursor.

.accordion-title {
	cursor: pointer;
}

.accordion-title:after {
	content: "+";
	float: right;
}

.accordion-title.open:after {
	content: "\2212";
}
