美吧？想学怎么做吗？很简单，也是拷贝和黏贴代码罢了。首先，去layout--->edit html
First, go to layout ---> edit html在<head>和</head>之间贴入以下的代码
Paste the code below under <head>
<script type="text/javascript">

在红色var color 那边，贴入你要的"星星“颜色的代码。
You may change the color of the "star", by replacing the code in red color by the hex color code that you want.
