之前看到有網站的游標長得像這樣，就一直很想用。這次花了些時間研究給弄好了。
這個原理其實很簡單，用兩個 div，border-radius: 50%; 呈現圓形。CSS 套用樣式，JavaScript 讓他跟隨滑鼠就完成。
在程式和樣式部分我參考了這個：
這是我修改後的程式與樣式，讓他更搭配我的主題，也另外增加了一些顏色與形狀的變化：

把以上兩個檔案存在 source 資料夾下，並且在設定文件中的 Inject 加入下面這行就可以，記得路徑要填對。

| <div id="cursor-border"></div><div id="cursor"></div><link rel="stylesheet" href="/css/custom_cursor.css"><script src="/js/custom_cursor.js"></script>
|
當然其他不是 butterfly，而是其他網站或主題也可以用。
