推荐答案
code> + 选择器意味着两个元素之间不能有任何其他元素。原因 + label 的工作原因是您的标签紧接在单选按钮之后。然而，标签位于单选按钮和 div 之间，因此＃radio-
The + selector means there must not be any other elements coming between the two elements. The reason + label works is because your label comes immediately after your radio button. However, that label is standing between your radio button and the div, so #radio-one:checked + div won't work.
您需要使用
#radio-one:checked + label + div a
另请参阅，说明 + selector工作。
