CSS tweaks for list items in main content area

Don't know where else to put this. The left half of the bullets were getting cut off. I made the following adjustments to style:

#columns {
position: relative;
float: left;
width: 100%;
margin-top:-20px;
margin-right: -34em;
margin-bottom:15px;
padding-right: 2em;
padding-left: 3px;
overflow:hidden;
}

li {
margin-left:15px;
}
