Question

我正在寻找一种解决方案，将光标悬停在Fancybox图像上时将光标更改为放大镜。

就像在Pinterest上一样，当你悬停图像时（使用chrome）。

到目前为止，我有这个没有跨浏览器支持。

.picture img {
    cursor:url(/img/layout/backgrounds/moz-zoom.gif), -moz-zoom-in;
}

有没有更好的方法来解决这个问题？

Answer 1

您可以使用：

.picture img{
    cursor: -moz-zoom-in; 
    cursor: -webkit-zoom-in; 
    cursor: zoom-in;
}

Answer 2

为此你需要使用游标文件.cur而不是 ~~.gif~~ 文件，所以它就像

.picture img {
    cursor:url(/img/layout/backgrounds/zoom.cur), -moz-zoom-in;
}

Answer 3

根据caniuse.com，相关浏览器现在都支持cursor: zoom-in;，当然除了IE。 w3schools的IE使用率下降到6.1％......时钟已经开始流行了IE！

.picture img{
   cursor: zoom-in;
}

Answer 4

我想出了一种让光标在图像上工作的方法，但它从来没有像光标一样工作
