如何制作环形旋转木马/滑块（带箭头）？
[英]How to make a looping carousel/slider (with arrows)?
问题描述
我目前正在为学校的网站编写代码，但似乎无法使滑块/轮播工作。
我正在尝试实现以下外观：
单击按钮时，图像必须滑动1张图片，并且该图片应该循环播放（这意味着消失的第一张图片应该显示在另一侧）
淡入淡出效果供以后使用，不要介意。
我尝试了很多事情，有些使用纯CSS，有些使用JS ...我愿意接受建议。
.slideshow { height: 240px; background-color: grey; overflow: hidden; position: relative; } .slide_content { display: flex; flex-direction: row; overflow: hidden; height: 100%; } .fluidimg { max-width: 100%; }
<button class="button js-prev"> < </button> <div class="slideshow js-slide"> <ul class="slide_content"> <li class="slide_item"><img src="img.png" class="fluidimg"></li> <li class="slide_item"><img src="img.png" class="fluidimg"></li> <li class="slide_item"><img src="img.png" class="fluidimg"></li> <li class="slide_item"><img src="img.png" class="fluidimg"></li> <li class="slide_item"><img src="img.png" class="fluidimg"></li> <li class="slide_item"><img src="img.png" class="fluidimg"></li> </ul> </div> <button class="button js-prev"> > </button>

这是我也用于项目的轮播，效果很好。 使用html，css和js分别命名的文件。
