我使用 CSS3 在我的网站中为 :hover 设置动画 - 当我在 Firefox 中运行它时，导航动画很完美，文本从左侧滑入 - 但是在 Chrome 和 Safari 中，它似乎不像在 Firefox 中那样做动画. 在 chrome 中，它似乎来自底部？
你可以在这里看到我的例子（它是左侧导航）：http ://www.wearewebstars.dk/frontend/Navigation/boerneunivers.html
导航的 HTML 是：
<div class="left-navigation fixed">
<nav class="left">
<ul id="nav">
<li class="li-blue">
<div class="border-left"></div>
<a href="#page1" class="left-link nav-blue" data-page="page1">
<div class="nav-icon"><img src="assets/css/boerne-img/menu/icon-blue.png" alt="" title="" /></div>
<span class="nav-text">Myanmar</span>
</a>
</li>
<li class="li-darkred">
<div class="border-left"></div>
<a href="#page2" class="left-link nav-darkred" data-page="page2">
<div class="nav-icon"><img src="assets/css/boerne-img/menu/icon-darkred.png" alt="" title="" /></div>
<span class="nav-text">Storbyen</span>
</a>
</li>
<li class="li-orange">
<div class="border-left"></div>
<a href="#page3" class="left-link nav-orange" data-page="page3">
