html - 导航栏( Bootstrap )在顶部占用空间 - 默认情况下我可以将它放在 slider 顶部吗

Question

可能是非常基本的问题，但我遇到了问题。我正在为我正在制作的网站使用 Bootstrap 设计。默认情况下，网站没有任何图像 slider 。

添加 img slider 后，我的导航栏似乎始终在其上方，而从不在 slider 上方，我不喜欢这种情况。这是示例:

这是您加载页面时的样子

这就是我希望它在您加载页面时的样子(请注意，当我向下滚动一点时它工作正常)

所以基本上我的导航工作得很好，它只是不在 slider 的顶部。

我将包括包含所有内容的整个 .css 文件，我将图像链接到 slider 并创建位于顶部的导航栏(不透明度为 0.7)。

我只是想让它在开始时位于 slider 的顶部，并在我滚动时继续位于所有内容的顶部(注意滚动在代码段中不起作用)。当滚动开始位置是我遇到的问题时，它工作正常。

也不要担心 slider 中图像上的蓝色东西。这是 WIP。

Answer 1

在 #header 上使用 position: absolute 会将其从静态布局流中取出， slider 应该“向上滑动”，可以这么说。您还需要指定宽度，因为它不在流程中:width: 100% 或 width: 100vw 应该有效。为了更好地衡量，您还应该添加 top: 0 和 left: 0。

您可能还需要设置一个 z-index。

请注意，我对 Bootstrap 不是很熟悉，可能有更多的“Bootstrap 方式”来完成此操作，但它应该可以工作。

另请注意，我不知道这是否会扰乱您使用的插件，使标题固定。
