{display:none} 不使用复选框？

Question

选中“与送货地址相同”时，该部分下方的表单应该会消失。我放了 {display:none} 但它不起作用。当我摆脱 {div class="checkboxalign} 但它不再在中心对齐时它起作用了。我想知道如何让这个功能工作，但仍然保持中心对齐？谢谢。

.checkbox-custom, .radio-custom {

Answer 1

因为.input-box 元素不是复选框的兄弟。你的选择器是

.checkbox-custom:checked ~.input-box {
  display: none;
}

Answer 2

必须有包装器 div 来形成要隐藏的元素，然后你的 css 才能工作。
