Footer Issues with Centering Lists
I've been working on the footer for my website and have all the links I need underneath the headers, but when I try to center it the longer links move over to the side and down like there's an indent. The shorter links center fine, it's just the longer ones. I'm trying to create a column based footer, where each section of links make up a column that goes across the page. Has anyone seen this before?


.container .main-section .article3 {
width: 300px;
float: left;
color: #FFFFFF;
text-align: center;
margin-left: 50px;
margin-right: 90px;
position: absolute;
}
.main-section .article3 h3 {
font-family: Gotham, "Helvetica Neue", Helvetica, Arial, sans-serif;
}
.main-section .article3 .footer {
list-style-type: none;
text-align: center;
float: none;
font-family: Gotham, "Helvetica Neue", Helvetica, Arial, sans-serif;
padding-bottom: 0px;
margin-top: 10px;
margin-bottom: 10px;
width: 300px;
display: table;
font-size: medium;
position: absolute;
}
.article3 .footer li {
margin-bottom: 10px;
text-align: center;
width: 300px;
float: left;
list-style-type: none;
display: table-cell;
position: relative;
vertical-align: middle;
max-width: 300px;
}<article class="article3">
