【问题描述】：

我正在尝试按照此站点中的示例进行操作：http://codepen.io/rogie/pen/jgrIu

但是，我没有像示例中那样获得所需的结果，而是得到以下结果：（我无法在开始时单击，而是在开始的顶部获得开始和可点击的检查）

我真的很新，如果有任何帮助，我将不胜感激。

谢谢

我使用以下代码创建了 html 文件：

<html>

//just styling for the number

<!-- js -->

<script type="text/javascript" src="/js/rating.js"></script>

</head>

<body>

<span class="star-rating">
  <input type="radio" name="rating" value="1"><i></i>
  <input type="radio" name="rating" value="2"><i></i>
  <input type="radio" name="rating" value="3"><i></i>
  <input type="radio" name="rating" value="4"><i></i>
  <input type="radio" name="rating" value="5"><i></i>
</span>
<strong class="choice">Choose a rating</strong>

</body>
</html>

这是JS代码

$(':radio').change(
function(){
$('.choice').text( this.value + ' stars' );
 } 
 )

【解决方案1】：

您引用的示例使用LESS。除非您将其编译为常规 css，否则它将无法在 Web 浏览器中运行，如下所示：

.star-rating {
  font-size: 0;
  white-space: nowrap;
  display: inline-block;
  width: 250px;
  height: 50px;
  overflow: hidden;

谢谢！！！！现在可以了。对不起我的无知，但甚至不知道什么是LESS。我以为是 CSS 中的，实际上是示例中所说的
@S. Martin：如果您查看 codepen 链接中 CSS 部分的顶部，您会看到“CSS (LESS)”。还有一个按钮显示“查看已编译”。单击该按钮将为您提供直接的 CSS，这可能是您想要的。
