我使用免费下载中包含的演示代码安装了Nivo Slider。
我在滑块中包含的所有图像都是800像素宽。
然而，它们被调整为1440像素宽。正在插入额外的代码：
<img src="images/bar.jpg" data-thumb="images/bar.jpg" alt="" title="" style="display: none; width: 1440px;">
我搜索过CSS和JS，但没有提到1440。
这个宽度在哪里设定？
答案 0 :(得分：5)
Nivo Slider默认是响应式的，如果你想限制滑块宽度，请在CSS中使用以下类
.slider-wrapper.theme-default {
width: 800px; /* Desired width */
}
如果您使用的是default主题的nivo滑块，如果您正在使用其他主题，则上述操作将有效，而不仅仅是将.theme-default更改为指定给主题的class主题滑块包装。

Use my custom nivo script code
