我使用的引导程序4删除了附件插件,替换为使用位置:粘性。作为单独的插件附件

但是,铬不支持。当移回自举3整个我的布局是拧。推荐的scrollpos-styler与bootstrap结合使用可怕。 (https://github.com/acch/scrollpos-styler

所以我想知道,是否有可能将词缀插件分开,所以我仍然可以在bootstrap 4中使用它?

是的,可以。

您可以复制从引导3.插件不要忘了申报所需的CSS类:

.affix { 
    position: fixed; 
    top: 1rem; 
} 

.affix-bottom { 
    position: absolute; 
}
