HTML 过渡不适用于 Grayfade

转载作者：行者123 更新时间：2023-11-28 00:01:04

我想做的是将鼠标悬停在我的图片上，然后使用 grayfade CSS 工具让它逐渐变灰。由于某种我不知道的原因，它不起作用，即使我已经在过渡上寻找了几个小时。请帮助我!

这是我的全部代码(尽管您想要查看的代码是样式标签中的 img 和 img:hover):

在此先感谢您帮助我解决过渡灰度渐变问题!

最佳答案

重新排序 transition 属性，似乎有一些干扰。放置 transition: filter 0.5s ease 首先似乎修复了它。我认为这与它正在覆盖其他前缀属性这一事实有关。

EXAMPLE HERE

img {
    transition: filter 0.5s ease;
    -moz-transition: -moz-filter 0.5s ease;
    -ms-transition: -ms-filter 0.5s ease;
    -o-transition: -o-filter 0.5s ease;
    -webkit-transition: -webkit-filter 0.5s ease;
}

img:hover {
    -webkit-filter: grayscale(100%);
    -moz-filter: grayscale(100%);
    -ms-filter: grayscale(100%);
    -o-filter: grayscale(100%);
    filter: grayscale(100%);
    filter: url(assets/grayscale.svg);
    filter: gray;
}
