使用CSS

Question

是否可以仅使用CSS自定义收音机和复选框的外观？我看到有很多关于这一点，但大多数解决方案需要使用图像和JavaScript。

看起来bootswatch.com的工作人员用纯CSS定制输入做得很好。我在这里简化了他们的方法： https://jsfiddle.net/mthomas9261/qujbq4gs/

HTML：

<input type="radio" value="a" name="test">
<input type="radio" value="b" name="test">

<input type="checkbox" name="a" value="a">
<input type="checkbox" name="b" value="b">

CSS：

/*****************************************************
******************      Radio        *****************
******************************************************/

/* Hide Original Radio Button */
input[type="radio"] {
  position: relative;
  margin-top: 6px;
  margin-right: 4px;
  vertical-align: top;
  border: none;
  background-color: transparent;
  -webkit-appearance: none;
  appearance: none;
  cursor: pointer;
}
/* Remove standard blue selection outline */
input[type="radio"]:focus {
  outline: none;
}
/* New radio button */
input[type="radio"]:before,
input[type="radio"]:after {
  content: "";
  display: block;
  width: 14px;
  height: 14px;
  border-radius: 50%;
  -webkit-transition: 240ms;
  -o-transition: 240ms;

  top: -2px;
  background-color: red;
  -webkit-transform: scale(0);
  -ms-transform: scale(0);

input[type="radio"]:after {
