Line Spacing

Any answers to above? I would like to reduce the line spacing of the post titles as well as the space between the post titles.

After a lot of searching and experimenting, this seems to be working for me:

.widget_ultimate_posts ul {
	font-size: 90%;}
.widget_ultimate_posts ul li {
	list-style-type: disc;}
.widget_ultimate_posts ul li {
	line-height: 1.5;
	margin: -15px -5px;
	padding: 0;}
