我希望這個棒球圖像位於贊助商名單後面的背景中。但是如果我在贊助商鏈接和贊助商頭上應用高z-index，則什麼都不會發生。z-index！important對我的分區沒有任何幫助
如果我嘗試在棒球上輸入負號z-index，它會落在我的主容器後面。然後我嘗試在我的主容器中添加一個更低的z-index，但那導致我的導航失敗。
爲什麼不z-index工作時，我把它應用到h2或a

您是否在span3上有更多的z-indexes？ – DiederikEEn 2013-05-01 14:27:32
我沒有看到你的班級「棒球」在任何地方使用。 – 2013-05-01 14:27:33
您的html中的元素與棒球類的位置在哪裏？你能否將棒球形象作爲span3的背景？ – 2013-05-01 14:27:40
