javascript - 在 SLIDER 中将图像设置为背景图像的问题

转载作者：太空宇宙更新时间：2023-11-04 09:00:42

我发现了这个非常酷的图像 slider 插件(http://www.jqueryscript.net/slideshow/Fullscreen-Responsive-Image-Slideshow-with-jQuery-Phoenix-Slider.html)。但我想将图像设置为背景图像。我只是不知道该怎么做。

谁能帮帮我？

最佳答案

试试这个:

首先你可以在你的jquery中添加这个文件

$(document).ready(function(){

    $('.phoenix-slider').phoenix({
        fullscreen: true,
        height: '85%'
    });

});
