Question

我有一个非常简单的问题，但是我找不到一个简单的答案。

我有一个如下复选框：

<input type="checkbox">

并且我想在选中此复选框时更改仅 背景色。

在CSS或JS中有一种简单的方法吗？

Answer 1

您可以简单地使用:checked伪类和:after伪元素为背景着色。

编辑：要获得复选框的完整背景，我们需要完全自定义该复选框。这是一个完整的CSS解决方案。

input[type="checkbox"]:checked {
  background: blue;
  color: white;
}

input[type="checkbox"] {
  cursor: pointer;
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;
  outline: 0;
  background: lightgray;
  height: 16px;
  width: 16px;
  border: 1px solid white;
  color: white;
}

input[type="checkbox"]:after {
  content: ' ';
  position: relative;
  left: 40%;
  top: 20%;
  width: 15%;
  height: 40%;
  border: solid #fff;
  border-width: 0 2px 2px 0;
  transform: rotate(50deg);
  display: none;
}

input[type="checkbox"]:checked:after {
  display: block;
}

<input type="checkbox" />

Answer 2

我编辑参考代码：reference
这是您至少需要编写的代码：

input[type="checkbox"] {
  visibility: hidden;
}
input[type="checkbox"] + label:before {
  border: 1px solid #333;
  content: "\00a0";
  display: inline-block;
  font: 16px/1em sans-serif;
  height: 16px;
  margin: 0 .25em 0 0;
  padding: 0;
  vertical-align: top;
  width: 16px;
}
input[type="checkbox"]:checked + label:before {
  background: red;
  color: green;
  content: "\2713";
  text-align: center;
}

      <input type="checkbox" id="Custom" name="Custom">
      <label for="Custom">Custom Check</label>
