javascript - 轮播正在与英雄图像和导航栏合并
问题描述
我正在制作一个有趣的小网站...我在https://www.w3schools.com的帮助下创建了 Hero Image 和 Navbar，还尝试添加 Carousel，但它似乎在 Navbar 和 Hero 之间合并图片...
参考： 没有旋转木马
使用轮播：合并！
我想要实现的是This但它应该在它下面，而不是合并到...
我尝试了很多方法并搜索了整个 StackOverFlow 站点，但似乎我有一个愚蠢的大脑，无法理解这个愚蠢的问题。
以下是一些源代码，以备不时之需： CSS

告诉我我做错了什么TT_TT
解决方案
我可以从这里看到的是您position:fixed在幻灯片容器上使用而不给它top属性。它会坚持top
尝试这个
/* 幻灯片容器 */
.slideshow-container {
max-width: 1000px;
position: fixed;
margin: auto;
z-index:4;
top:50px;
}
