javascript - 如何居中 gridster.js？

Question

我一直在玩 Gridster.js，但就我的生活而言，我似乎无法使网格居中，它总是左对齐，我已经尝试了很多次，但也许我遗漏了一些东西..

我制作了一个包含我的网格基础的 jsfiddle，我希望有人能解决它并帮助我将它居中，拜托:)

.gridster {
    background: #004756;
       margin: 0 auto;
    opacity: .8;

    -o-transition: opacity .6s;
    -ms-transition: opacity .6s;
    transition: opacity .6s;
    text-align: center;

.gridster > * {
    margin: 0 auto;

    overflow-y: hidden;

.gridAlignerWrapper {

    width: 100%;
    height: 100%;
}

.gridAligner {
    width: 100%;
    display: table-cell;
        }

body {
    background-color: #EEEEEE;
    font-family: 'Helvetica Neue', Arial, sans-serif;
    -webkit-font-smoothing: antialiased;
    font-size: x-small;
    color: #666666;
    text-align: center;
      vertical-align: middle;
}

ul, ol {
    list-style: none;
    margin:0 auto;
      text-align: center;
      vertical-align: middle;


}

h1 {
  margin-bottom: 12px;
  text-align: center;
  font-size: 30px;
  font-weight: 400; 
}

h3 {
  font-size: 25px;
  font-weight: 600;
  color: white; 
}

/* Uncomment this if you set helper : "clone" in draggable options */
/*.gridster .player {
  opacity:0;
}*/
