尽管类不同，但动画仅在一个复选框上发生

Question

我找到了一个我确实想要使用的复选框，但是当我添加多个复选框时，动画仅适用于第一个。

我尝试创建像.cbx2和.inp-cbx2之类的新类，并应用相同的样式，但是动画仍然仅适用于第一个复选框。

能否请您解释我要去哪里错了？

谢谢。

CSS中存在类的全部原因是使您的样式可在多个元素之间重用。无需复制CSS。

在使用与第一个相同的类时，第二个复选框不起作用的原因是因为您尚未更新第二个标签的for属性。此属性告诉浏览器id的单击标签时应生效的form元素。

您的情况下，第二个标签应如下所示：

<label class="cbx" for="cbx2"><span>

.cbx {
