Question

我甚至不确定为什么会发生这种情况，这是一个Css错误，但我不确定在哪里

正如你可以看到元素＆＃34;票＆＃34;隐藏在卡片后面（不知道为什么），我想要将图片放在图片上方，这样它就可以编辑了！

这是代码

的CSS

// Place all the styles related to the view controller here.

Answer 1

您的卡位于机票后面的.row div中。在DOM中向下的元素具有比DOM中它们上面的元素更高的z位置并且在它们的“前面”出现。要更改常规层次结构，请使用z-index属性。

.row {
    z-index: 1;
}

您还可以撤消HTML的层次结构，以便故障单位于.row之后。这可行，因为您的自然层次结构现在将票证置于.row之上。

Answer 2

要强制ticket元素转到上一个元素（新行）的底部，请尝试添加.ticket css：
