In your CSS you have the followings styles that are setting list items:
ul li:first-child {
margin-left: 20px;
}
li {
border-left: 1px solid #C5C5C5;
display: inline;
float: left;
font-size: 0.9em;
margin: 3px auto;
text-align: center;
}
Add this CSS to over ride those styles in the content:
.DetailsPage li:first-child {
margin-left: 0;
}
.DetailsPage li {
border: 0 none;
display: list-item;
float: none;
text-align: left;
}
