This will get what you want:

.general {
    background-color: rgb(255, 255, 255);
    border-radius: 8px 8px 8px 8px;
    box-shadow: 0px 0px 4px rgba(0, 0, 0, 0.3);
    margin-bottom: 30px;
    padding: 10px;
    text-align:center;
}

.list{
    margin-bottom: 20px;
    text-align: left;
    margin: 0 auto;
    display: inline-block;
}

It will also work with any width. See here: http://jsfiddle.net/KS4eS/8/
