Answer 1

试试这个：

对于第一个span：

input:checked ~ span:first-of-type {
  color: red;
}

input:checked ~ span:first-of-type {
  color: red;
}

<input type="checkbox" name="">Click
<br><span>mohammedSerwan</span>
<br><span>Mohammed2</span>

对于所有span所以使用~：

input:checked ~ span {
  color: red;
}

input:checked ~ span {
  color: red;
}

<input type="checkbox" name="">Click
<br><span>mohammedSerwan</span>
<br><span>Mohammed2</span>
