Question

我想从bootstrap（下面的链接中的codepen）采用半页背景滑块模板，但是在桌面上调整页面大小时遇到了困难，因为背景图像没有相应地调整大小。半滑块的高度和重量设置的解释将非常感激。

目前的实施方案在移动设备和平板电脑设备上以横向视图挡住了照片的顶部，这就是我尝试调整半滑块照片大小的原因，因为页面的其余部分已调整大小。

好的你可能有两种解决方法：

1）制作你的navbar-fixed-top class == compute all four compute 1 compute 2 compute 3 compute 4 == compute first two compute 1 compute 2 == compute one only compute 1 == all as a list compute 1 compute 2 compute 3 compute 4

OR

2）为您的轮播班级position: relative
