Transition

在鼠标悬停元素时，在两个状态之间创建平滑过渡。

用法

要在悬停或聚焦时切换过渡效果，为父元素添加 .uk-transition-toggle 类。同时添加 tabindex="0"，让动画可以通过键盘导航聚焦，并在触屏设备上生效。为任意子元素添加 .uk-transition-* 类之一，即可应用实际的过渡效果。

类	说明
`.uk-transition-fade`	让元素淡入
`.uk-transition-scale-up` `.uk-transition-scale-down`	元素放大或缩小。
`.uk-transition-slide-top` `.uk-transition-slide-bottom` `.uk-transition-slide-left` `.uk-transition-slide-right`	让元素从顶部的方向滑入
`.uk-transition-slide-top-small` `.uk-transition-slide-bottom-small` `.uk-transition-slide-left-small` `.uk-transition-slide-right-small`	元素以较小的距离从上、下、左或右方向滑入。
`.uk-transition-slide-top-medium` `.uk-transition-slide-bottom-medium` `.uk-transition-slide-left-medium` `.uk-transition-slide-right-medium`	元素以中等距离从上、下、左或右方向滑入。

该组件通常与 Overlay 组件配合使用，因为元素是从不可见状态过渡到可见状态。要将覆盖层放置在另一个元素（例如图片）之上，可使用 Position 组件。
