所以我有一個旋轉器,它的效果很好。但是主箱子是由最大的圖像決定的。所有圖像(如果較小等)應該漂浮在主框的中心。不過,我的保證金編輯似乎沒有在代碼中做任何事情。任何想法爲什麼他們不適用?動態元素絕對中心

[**定心 - 完整的導向**](http://css-tricks.com/centering-css-complete-guide/)注 - '頂部:50% ,左:50%'不居中......它將左上角置於中心。 – 2014-10-30 20:04:08
@Paulie_D請參閱代碼... jQuery是手頭的問題........我用'calc(50% - '+ parseInt(images.eq(imgcur))嘗試了頂部/底部。 height())+')''也無濟於事。 – WAS 2014-10-30 20:09:47
您正在將圖像錯誤地放置在第一位......也許Jquery **不是**問題。 – 2014-10-30 20:11:44
