问题描述

HTML 结构

<div id="small_gal">
    <div><img src="images1.jpg" /></div>
    <div><img src="images1.jpg" /></div>
    <div><img src="images1.jpg" /></div>
    <div><img src="images1.jpg" /></div>
    <div><img src="images1.jpg" /></div>
    <div><img src="images1.jpg" /></div>
    <div><img src="images1.jpg" /></div>
    <div><img src="images1.jpg" /></div>
</div>

图像有阴影,所以 border 不是解决方案,因为它会在图像之外

The images are having dropshadows so border is not a solution, as it will be outside the image

边框有过渡,在 FF 上可以流畅运行,但在 chrome 或其他浏览器中不行

The border is having transition and it works smoothly on FF but not in chrome or other browsers

这是我使用的代码

#small_gal div:hover{cursor: pointer;}
#small_gal div:after {
    content: '';
    position: absolute;
    width: 112px;
    height: 81px;
    border: 3px solid #e27501;
    left: 9px; top: 9px;
    z-index: 9;

    opacity: 0;
    -webkit-transition: opacity 0.5s ease-in-out;
    -moz-transition: opacity 0.5s ease-in-out;
    -o-transition: opacity 0.5s ease-in-out;
    -ms-transition: opacity 0.5s ease-in-out;
    transition: opacity 0.5s ease-in-out;
}
#small_gal div:hover:after {
    opacity: 1;
}

注意:

#small_gal

只是容器每个图像都包含在一个 div 中,因此我们可以实现 :after

is only the container each image is wrapped in a div so we can implement :after

推荐答案

Firefox 4+ 是唯一支持 :before:after<等伪元素过渡的浏览器/代码>.

Firefox 4+ is the only browser that supports the transitioning of pseudo-elements such as :before and :after.
