Question

enter image description here我有两个不同的对象，当我将鼠标悬停在每个对象上时，将出现一个巨大的文本框，该文本框与相对的对象重叠。当我将鼠标悬停在两个框上时，我需要将其z-index设置为2。我的问题是我可以一次操作其中一个框，但不能同时操作。

我将html放置在问题的左侧。

图片链接位于帖子的底部。我提供了3张不同的图片。enter image description here

安全利益充气不足的轮胎仍然是导致轮胎故障的第一大原因。在不适当的压力下运行会导致热量积聚，板层分离，侧壁/套管损坏等等，仅在美国，每年就导致40,000多起事故和600多人死亡。

此外，不适当的充气会削弱制动能力和车辆操纵性能，从而给驾驶员带来进一步的安全并发症。

保护您的操作员和设备。货币收益以最佳压力运行轮胎可为驾驶员和车队带来众多金钱优势，包括：
