基本上,我想做的是在 :hover:before 元素上应用转换并进行转换,这样当您将鼠标悬停在 ava.png 上时,:before 元素会平滑地出现,而不是立即出现。
我尝试将转换代码添加到 :hover:after 类中(如下面的代码所示),并且尝试了我在 StackOverflow 上找到的解决方案之一,将 :hover 更改为 :before 并添加内容 + 转换到那个类(class)。不用说我的尝试都没有成功,否则我现在就不会在这里。 (:D)
如果有人能花时间帮助我,我将不胜感激,谢谢!

最佳答案
要对过渡进行动画处理,您需要对元素属性进行某种更改。这意味着该元素应该是页面的一部分,显示(即没有 display: none
)和可见(没有 visibility: hidden
),但以某种方式不可见/透明(例如 opacity: 0
)。
就您而言,您不会创建 :before
元素,除非你想显示它。为了解决这个问题,渲染 :before
与 scale(0)
,然后将其更改为 scale(1)
