我已经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。
但是，它们的大小正在调整为 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;">
我搜索了 CSS 和 JS 并没有找到 1440 的提及。
这个宽度在哪里设置？

Nivo Slider 默认是响应式的，如果你想限制滑块的宽度，在你的 CSS 中使用下面的类
.slider-wrapper.theme-default {
width: 800px; /* Desired width */
}
default如果您使用的是 nivo 滑块的主题，如果您使用的是其他主题，则上述方法将起作用，而不是简单地将分配给滑块包装器的主题更改.theme-default为特定主题。class

When you initial nivoSlide pass my new parameter backgroundSize:'your width size px your height size px';
Example:
$('#slider').nivoSlider({
backgroundSize:'687px 400px',
effect: 'random',
animSpeed: 500,
pauseTime: 3000,
directionNav: true,
controlNav: true,
controlNavThumbs: false,
pauseOnHover: true});
});
