我正在尝试制作一个示例原型(prototype)，该原型(prototype)使用 Bootstrap 4 中的两张卡来显示表单中的信息，并在第二张卡中保存来自第二个相关表单的信息。现在，它看起来像这样:
Here is a JSFiddle with the code我已经采取了在样式标记中引入特定类和选择器的步骤。

需要更改哪些内容才能使两张卡具有正确的(图像顶部)样式？
最佳答案
您的 jsfiddle 第 83 行的 html 中有一个拼写错误:
<div="card-header wuformheader">
应该是:
<div class="card-header wuformheader">
您删除了“class”一词
关于javascript - 所有卡片均未设计样式，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48119224/
