我認爲它可能與僞元素有關,但我不確定。我在使用css3進行變換轉換時遇到了困難。在Firefox v24中,效果按照我的要求運行 - 請參閱CodePen http://codepen.io/patrickwc/pen/aKEec,但在Chrome和IE中,鏈接的邊框效果會生成動畫,然後突然切換回位置。這很難描述,所以最好的方法是在Firefox或IE或Chrome瀏覽器中查看效果。Firefox和Chrome和IE瀏覽器的CSS3變換區別

我有一種感覺,與變換原點搞亂可能修復它,但我一直無法得到那個工作。任何幫助或解釋的差異將不勝感激。
謝謝,這樣做更有意義。我從另一個網站上的教程複製了這段代碼([codrops](http://codrops.com)),所以我也會讓作者知道。雖然他們保持他們的線(寬度:)相同的大小,所以沒有意識到問題。 – patrickzdb
