我正在继续开发我的网站，但现在遇到了另一个问题。
当导航栏在较小的屏幕上折叠时，会出现一个滚动条，表明元素溢出。
我尝试使用 overflow:hidden 属性来消除 CSS 中的此问题，但它似乎无法正常工作。
请参阅下面的屏幕截图和代码片段以了解问题。

如何去掉这个滚动条？
最佳答案
事实上，这个问题比看起来更容易回答。
在Bootstrap中，bootstrap.css文件中确实默认启用了overflow - x属性。
.navbar-collapse {
padding-right: 15px;
padding-left: 15px;
overflow-x: visible;
-webkit-overflow-scrolling: touch;
border-top: 1px solid transparent;
-webkit-box-shadow: inset 0 1px 0 rgba(255, 255, 255, .1);
box-shadow: inset 0 1px 0 rgba(255, 255, 255, .1);
}
要解决这个问题，需要进行简单的属性更改。
溢出-x:隐藏
所以不再需要在折叠的导航栏上滚动!
关于javascript - Bootstrap Nav Collapse(导航)滚动 - 需要 overflow hidden ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34371819/
