代码在上面。我希望所有项目都在导航栏的中间。而导航品牌则处于中间位置。请有人支持。这些项目应该在导航栏中居中。
答案 0 :(得分:0)
目前, navbar-collapse
占用了所有可用空间。将 flex-grow: 1
覆盖为 flex-grow: 0
,以便占用所需的空间。使用 flex-grow-0
来执行此操作。
要对齐中心的所有导航项,请使用 justify-content-center
作为 navbar
。但是,如果您想在大屏幕中间对齐它们,请改用 justify-content-lg-center
。

除了jQuery
之外,大多数引导程序组件都需要popper.js
和bootstrap.js
,因此您需要添加所有这些组件。
