我正在为学校项目创建一个网站，我们被要求选择一家公司来设计一个模拟促销网站。我选择了CVS，但你可以选择任何人。我设法使用了一个模板，我已经完成了一些codecamdemy课程，但教程似乎没有帮助改变图像的长度。我想要做的是在整个幻灯片容器的长度上扩展名为“nyse”，“mentor”和“mountain”的图像，但到目前为止，当我更改它时，图像似乎没有做任何事情。任何人都可以告诉我它出错的地方或在哪里放置我的代码来扩展图像？我尝试了很多div但到目前为止没有运气。我的代码如下所示。

答案 0 :(得分：1)
继承人 DEMO FIDDLE （您只需将图片网址添加到CSS）
您需要做的第一件事是添加e.preventDefault（）;对你的点击偶像这样：
$('.arrow-next').click(function(e) {
e.preventDefault();
//..more code
});
$('.arrow-prev').click(function(e) {
e.preventDefault();
//..more code
});
然后你需要给每张幻灯片一个唯一的ID并给它一个背景图像，就像你有.slide功能的背景一样：
HTML：
<div id="nyce-slide" class="slide">
<!-- ...code.. -->
</div>
<div id="mountain-slide" class="slide">
<!-- ...code.. -->
</div>
<div id="mentor-slide" class="slide">
<!-- ...code.. -->
</div>
CSS：
.slide {
text-align: center;
height: 550px;
}
#nyce-slide{
background-image: url('nyce.jpg');
}
#mentor-slide{
background-image: url('mentor.jpg');
}
#mountain-slide{
background-image: url('mountain.jpg');
}
