Question

<style>
input[type=checkbox]{display:none}
label{color: black;}
input[type=checkbox]:checked + label{color:red;}
</style>

<label><input type="checkbox">Click</label>

我有一个复选框使用标签点击，当点击复选框时，标签应该改变颜色。我试图实现的是do it without for="id"。我将输入放在标签内，但颜色不会改变。

没有id，有没有办法做到这一点？

Answer 1

如果有人偶然发现了这个老问题，我想拿Vangel Tzo的答案进行一点优化。我建议将position:absolute;和position:relative;字段的label和input切换为允许较长的文本正确换行而不会在其下面重叠任何内容：

.hidden-checkboxes {
  font: 14px 'Open Sans', sans-serif;
}

.hidden-checkboxes input[type=checkbox] {
  position: absolute;
  left: 0;
  top: 0;
  display: inline-block;
  width: 100%;
  z-index: 1;
  opacity: 0;
  height: 30px;
}
.hidden-checkboxes label {
  position: relative;
  left: 0;
  top: 0;
  padding: 5px;
  display: inline-block;
  width: 100%;
}

.hidden-checkboxes input[type=checkbox]:checked + label {
  background: #3298dc;
  color: white;
}

.hidden-checkboxes div {
  position: relative;
  margin-bottom: 1px;
}

<div class="hidden-checkboxes" style="width:300px;">
  <div>
    <input type="checkbox"><label>Check me please.</label>
  </div>
  <div>
    <input type="checkbox"><label>Or how about me?</label>
  </div>
  <div>
    <input type="checkbox"><label>How about some long text that will cause wrapping of text?</label>
  </div>  
</div>

备注：字体和margin-bottom仅用于设计演示的样式。

这有点像黑客，但你可以使用这样的东西：

输入外部标签..

<input type="checkbox"><label>Click</label>

input[type=checkbox] { 
    display: inline-block;
    width: 100%;
    position: relative;
    z-index: 1;
    opacity: 0;
}
label {
    position: absolute;
    top: 8px;
    color: black;
}

input[type=checkbox]:checked + label {
    color: red;
}

复选框使用不带id的标签（标签css可以更改）
