Javascript 如何设置gridster.js的中心？

我一直在玩Gridster.js，但就我的一生而言，我似乎无法使网格居中，它总是左对齐，我尝试了又尝试，但可能我错过了一些东西

我已经制作了一个JSFIDLE，它具有我的网格的基础，我希望有人能够解决它并帮助我将其居中，请：）

谢谢

谢谢Paulie_D，我设法解决了这个问题并把它放在中心：）

它是居中的…但它也是100%宽的…不知道你在问什么。你说它居中是什么意思？当我查看JSFIDLE（和我的live站点）时，框都是左对齐的，右边有很多未使用的空间，因为我的网格只有5列，我希望5列网格位于彩色包装的中心。然后需要在包含的div上设置一个宽度，以便

边距：auto

将其置于包装内的中心。确定，我仍然不能按照我的预期工作，你能用你的意思更新JSFIDLE，让我看到它工作吗？
