打开Bootstrap模式时禁用滚动条

标签: html css twitter-bootstrap twitter-bootstrap-3 scrollbar

我使用以下代码使页面的滚动条始终可见:

html {
    overflow-y: scroll; 
}

但是,当打开Bootstrap模式时,主滚动条不可用(可见但禁用),当尝试某些代码时,如下所示无法解决问题。

.modal-open {    
    overflow-y: scroll !important; 
}

我想尝试以下方法:

1)我希望即使模态打开也启用主滚动条

2)我希望模态的滚动条自动可见,但是当我使用overflow-y时:滚动;模态体的高度不能自动增加,模态内容上的滚动条似乎被禁用(当我设置高度时,滚动条已启用,但ı想要使用自动高度)。有什么想法吗?

尝试更改此行:

.modal-open {    
   overflow-y: scroll !important; 
}

为:

body.modal-open {
  overflow: scroll; !important;
}

body.modal-open {
  overflow: scroll; !important;
