Question

我正在使用Bootstrap 4开发一个项目。我想制作一个导航栏。但是我没有。我搜索并找到了一些bootstrap 3代码。我尝试了这些代码，但没有得到结果。我想执行与该链接上的导航栏相同的操作，但是要使用bootstrap4。我正在尝试添加导航栏。我没看见它。您能帮我制作类似此链接的导航栏吗？我希望轮播全屏显示，我可以做到。对不起，我的语言不好。（响应）

Answer 1

当然。

这很容易做到。看看他们网站上的Carousel示例页面。

https://getbootstrap.com/docs/4.1/examples/

从那里开始，您需要做的就是将主要部分/轮播（应该有一个名为main的角色标签）固定在顶部，并使导航栏上的z索引位于轮播的前面（我相信按照标准大约是1090）

更改导航栏的宽度就像更改样式或将其放入容器一样简单。

尝试一下，让我们知道是否遇到任何麻烦。
