在css图像菜单中更改当前不透明度

时间:2022-12-30 18:53:20

I have a menu of images where the opacity changes to 1 in the hover state. I also want the "current" member of the list to have an opacity of 1. At this point, the hovering works fine (though I suspect the CSS is inefficient), but the "current" image of the mole remains at the same reduced opacity as the other images.

我有一个图像菜单,其中不透明度在悬停状态下变为1。我还希望列表中的“当前”成员的不透明度为1.此时,悬停工作正常(虽然我怀疑CSS效率低下),但痣的“当前”图像保持不变不透明度与其他图像一样。
