如何使用带有 img 标签的 CSS 过渡获得圆形悬停效果？答案

【问题标题】：How to get Circle Hover Effects with CSS Transitions with img tag?如何使用带有 img 标签的 CSS 过渡获得圆形悬停效果？
【发布时间】：2016-05-24 10:35:40
【问题描述】：

我想要在 <img> 标签上使用 CSS 过渡的圆形悬停效果而不将图像称为背景图像。

我已经创建了我想要的效果的JSFiddle。但是在这个小提琴中，图像被用作背景图像。我想要同样的效果，但在 img 标签中使用图像，而不是作为背景图像。

【问题讨论】：

添加您的代码以及到目前为止您尝试过的内容，天哪，我也想要这么多东西 ;)
能不能换个说法，太难理解了！！
现在能看懂了吗？？？ :) 请帮忙

标签： html css effects

【解决方案1】：

我在这里编辑了你的小提琴：http://jsfiddle.net/pedwf80h/7/

基本上我已经将 img url 从背景移到了 li 元素中。然后绝对定位 img 并使用 z-index 将其移到后面。然后 li 元素使用 overflow: hidden 和 border-radius: 100% 隐藏任何超出我们的 li 元素的图像。

希望这会有所帮助！
